DIRECT TESTIMONY OF DR. DON READING
May 4, 2012
I INTRODUCTION
2
3 Q. PLEASE STATE YOUR NAME AND BUSINESS ADDRESS.
4 A. My name is Don Reading and my business address is 6070 Hill Road, Boise, Idaho. I am
5 a principal with Ben Johnson Associates.
6 Q. HAVE YOU PREPARED AN EXHIBIT OUTLINING YOUR QUALIFICATIONS
7 AND BACKGROUND?
8 A. Yes. Exhibit No. 501 serves that purpose.
9 Q. On whose behalf are you testifying?
10 A. I have been retained by the Clearwater Paper Corporation, the J. R. Simplot Company
11 and Exergy Development Group of Idaho.
12 Q. WHAT ARE THE INTERESTS OF THOSE THREE ENTITIES IN THIS
13 DOCKET?
14
15 A. Clearwater Paper Corporation owns a large paper manufacturing facility near Lewiston,
16 Idaho. As part of its operations it generates electricity and sells that electricity to Avsita as a
17 qualifying facility (QF) under the Public Utility Regulatory Policies Act of 1978 (PURPA).
18 Cogenerating power at the Lewiston facility helps make it more profitable and stable. This is
19 important because Clearwater is Nez Perce County's single largest employer. Clearwater
20 directly employs about 1,300 people in Lewiston, almost seven percent of the total Nez Perce
21 County workforce. If it were to close, Nez Perce County's unemployment rate would double
22 from six and a half percent to almost fourteen percent. Clearwater is in the process of

1 negotiating an extension of its existing contract with Avista. That contract expires next year. So
2 it is very interested in the outcome of this dock
3 The J. R. Simplot Company generates electricity at its Pocatello, Idaho phosphate
4 fertilizer facility. It sells its electricity to Idaho Power under a PURPA contract that is set to
5 expire next year. Like Clearwater in Lewiston, Simplot is a major employer in Pocatello. It
6 employs almost 350 people directly in the facility and another 200 at its Smokey Canyon Mine
7 All of the Smokey Canyon Mine's production is delivered to the Simplot Pocatello facility.
8 These five hundred and fifty jobs are made more secure and stable due to Simplot's ability to sell
9 its electricity to Idaho Power.
10 Exergy Development Group of Idaho is a successful renewable energy developer
11 throughout the country. Its main office is in Boise, Idaho. It is responsible for bringing
12 hundreds of megawatts of wind energy projects on line in Idaho over the past several years It
13 developed the very first utility scale wind project in the state. Exergy is obviously very
14 interested in the outcome of this docket as its business model is, in part, based on PURPA.
15 Q. WHAT IS THE PURPOSE OF YOUR TESTIMONY IN THIS CASE?
16 A. My testimony will address both to the avoided cost methodologies that I recommend
17 should be utilized by the Idaho Public Utilities Commission (Commission) to set standard and
18 non-standard avoided cost rates, as well as other QF issues. In Part 1 of my testimony, I will first
19 address why I believe the Commission should not make significant revisions to the surrogate
20 avoided resource (SAR) methodology for standard or published rates, and then I will address the
Reading DI
Clearwater, Simplot, Exergy
-2
I Commission's implementation of IRP Methodology rates for projects above the eligibility cap
2 for published rates. In this section of my testimony I recommend to the Commission:
3 (1) That no deficit period be allowed and that QFs should receive capacity
4 payments for the full term of their contract;
5 (2) That if the IRP is going to be used for setting rates that it needs to be
6 litigated before the Commission through the hearing process;
7 (3) That input variables not be allowed to change between approved IRPs
8 with the exception of natural gas prices forecasts from a third party transparent
9 source; and
10 (4) That the single model run method proposed by Idaho Power be rejected.
11 In Part 2 of my testimony, I will address other issues related to PURPA and QF contracts.
12 I will explain why I recommend the Commission adopt or reaffirm the following QF policies:
13 (1) That liquidated damages provisions in QF contracts be tied to an estimate
14 of a utility's actual damages, and that QF contracts should likewise contain terms
15 protecting QFs in the event of a utility default;
16 (2) That QFs not be required to achieve on line status within 2 years of
17 signing a contract;
18 (3) That the standard term available for QF contracts remain at 20 years;
19 (4) That Idaho Power's economic curtailment tariff proposed for existing and
20 new QFs not be approved;
Reading DI
Clearwater, Simplot, Exergy
-3
1 (5) That a QF contracting tariff contain meaningful contract negotiation
2 guidelines and fair standard contracts for QFs choosing to sell their output on a
3 nonfirm basis and those choosing to sell pursuant to a legally enforceable
obligation;
(6) That QFs own environmental attributes in Idaho QF contracts because the
avoided cost rates do not compensation the QFs for more than the energy and
7 capacity alone; and
8 (7) That QFs will receive the same credit for transmission level upgrades
9 necessitated for their interconnection as non-QF generators and utility-owned
10 resources.

12 PART 1: AVOIDED COST RATE CALCULATIONS
13 I. PUBLISHED RATES
14 Q. DO YOU BELIEVE THERE ARE ANY COMPELLING REASONS FOR THE
15 COMMISSION TO CHANGE COURSE BY USING THE INTEGRATED RESOURCE
16 PLAN (IRP) METHODOLOGY INSTEAD OF THE SURROGATE AVOIDED
17 RESOURCE (SAR) FOR SMALLER PROJECTS?
18 A. No. The proxy or SAR method for determining a utility's avoided cost rates was the
19 method adopted by the Commission in 1980 when it first addressed its obligation to implement
20 the then new federal law. In my opinion, the SAR methodology has been a successful,
Reading DI
Clearwater, Simplot, Exergy
-4
transparent and effective method for estimating a utility's avoided cost rates.
2 Q. WHAT DID THE COMMISSION SAY ABOUT THE SAR METHODOLOGY
3 WHEN IT FIRST ADOPTED IT?
4 A. The Commission made it clear that it was laying a solid foundation for determining
5 avoided cost rates for the utilities it regulates by saying:
6 This Commission endorses the policy of having each utility pay its full avoided cost
7 when purchasing power from cogenerators and small power producers. Such a price will
8 bring about the equilibrium solution typical of a competitive market where the marginal
9 cost of all firms producing a like product is equal. Anything less will fail to bring about
10 the condition of a free, competitive market and will leave the utility, as the sole buyer, in
11 a position to dictate price as it sees fit.'
12
13 In this Order the Commission stressed that the price offered to QFs must be set at level that
14 would foster a competitive market or the utility would be left to dictate the price. The SAR or
15 proxy methodology was re-litigated in 1989 in Case No. U-1500-170. In that case the
16 Commission stated:
17 We find no avoided cost methodology presented in this case that is pragmatically
18 superior to the existing surrogate avoidable resource (SAR) method. Nor do we find a
19 method for determining the estimated time of load-resource balance that is superior to
20 using each specific utility's most recent load- resource plan (as incorporated in its Resource
21 Management Report) as the basis for a Commission determination establishing surrogate
22 utility specific resource plans following public hearing. Furthermore, we find that the most
23 appropriate surrogate resource for determining avoidable long term costs for utilities
24 operating in Idaho is a single hypothetical coal-fired steam plant with state of the art
25 emission controls. A surrogate resource is merely a means of estimating the value of energy
26 and capacity. The proxy unit need not actually be within a utility's resource plan.2
27
28 In that case none of the parties opposed the use of the proxy method and, indeed, all supported
1 IPUC Order 15746, Case No. P-300-12 (1980).
2 IPUC Order 22636, pp. 67-68, Case No. U-1500-179 (1989).

the SAR methodology. Commission Staff in particular was helpful, as the Commission observed
2 in its order,
Staff admits that any method of administratively establishing avoided costs is "based, at
least in part, upon a fiction." In no small part, this is due to the vagaries of forecasting. One
of the advantages cited by Staff in the present SAR methodology is that it does not require a
detailed analysis of utility planned resources. Staff contends that a single Idaho avoided cost
rate would have the advantage of simplicity of application and administration. Although the
SAR method was described as consisting of seven steps, implementation of those steps
requires the Commission to establish at least 29 variables for computing avoided costs. The
set-point for most variables is selected from a range of reasonable values.
Staff recommends (1) maintaining the existing method of computing avoided costs,
(2) establishing a single avoided cost rate for all Idaho [sic.], and (3) establishing an
automatic method of periodically revisiting the variables.3
Numerous IPUC cases can be cited describing the rational for using the SAR methodology as a
reasonable and transparent method for determining avoided cost rates for the state's investor-
owned utilities.
Q. HAVE THERE BEEN ANY MAJOR CHANGES TO THE SAR METHODOLOGY
SINCE IT WAS FIRST ADOPTED BY THE COMMISSION IN 1980?
21 A. Yes. The one major change was in a 1993 case.4 In that case, the Commission
22 concluded that the avoidable resource should be changed to a natural gas-fired combined-cycle
23 combustion turbine rather that a coal-fired generating plant.
24 Q. IT HAS BEEN THIRTY TWO YEARS SINCE THE SAR WAS FIRST ADOPTED

1 BY THE COMMISSION, HAVE CONDITIONS CHANGED SUCH THAT IT IS NO
2 LONGER RELEVANT FOR ESTIMATING AVOIDED COST RATES?
3 A. No. Quite the opposite, in fact. Idaho's energy picture has vacillated dramatically over
4 the past three decades. We have had periods of surplus and periods of deficit. We have
5 experienced periods of high load growth and low or even at times negative load growth. We
6 have had periods of high inflation and low inflation. We have had droughts and record water
7 years. The SAR methodology has been robust through all of those changes and has produced
8 avoided cost rates that have proven to be remarkably accurate in hindsight. Currently, I do not
9 see any conditions that would constitute a compelling reason to change Commission precedent at
10 this time by abandoning the SAR for setting avoided cost rates.
11 Q. WHAT POSITION HAVE THE UTILITIES TAKEN IN THIS DOCKET
12 RELATIVE TO THE SAR METHODOLOGY?
13 A. In addition to my testimony discussing the utilities positions, I have also included
14 Exhibit No. 502, which includes several discovery responses regarding the avoided cost rates.
15 Idaho Power is an outlier in that it is the only utility recommending the SAR methodology be
16 abandoned. Both Rocky Mountain Power and Avista advocate maintaining the SAR
17 methodology for standard contracts while supporting a cap of 100 kw for wind and solar
18 projects to be eligible for published rates. According to the testimony of Rocky Mountain
19 Power's witness Kelcey Brown:
Reading DI
Clearwater, Simplot, Exergy
-7
The Company's position is that the current implementations of the SAR and IRP
methodologies are appropriate for the published and negotiated avoided cost rates,
respectively, as long as the 100 kW eligibility cap threshold for wind and solar
QFs is maintained for published SAR rates. The SAR methodology used for
calculating published avoided cost rates for smaller QFs continues to provide a
simple and transparent means of pricing that minimizes transaction costs a very
small QF might incur to negotiate a power purchase agreement. However, the
SAR methodology is not the best methodology as the QF project capacity
increases since it does not take into consideration the value a specific QF project
would provide to each utility's unique power system and does not account for the
characteristics of each individual QF.5
I certainly agree with Ms. Brown in that the SAR methodology continues to provide a simple and
transparent means of pricing and that it helps to keep the transaction costs down. I would add,
however, that the benefit of reduced transaction costs inures to both the QF developer AND the
utility.
Q. IS THE SAR METHODOLOGY WIDELY ACCEPTED?
A. Yes, even Idaho Power witness William Hieronymus seems to agree. He cites a 1992
National Economic Research Associates (NERA) survey that he states might be 20 years old but,
"still is representative of administratively determined avoided methods in use today. ,6 This
survey indicated that 14 states, out of 49 surveyed used some form of the proxy method in
determining avoided cost rates for PURPA projects. This indicates the SAR method is widely
accepted as valid method for determining avoided cost rates.

1 HISTORY AS IT RELATES TO A COMBINED CYCLE COMBUSTION TURBINE?
2 A. Yes. Each of the three utilities have either recently added or will add a CCCT to their
3 generating system. It is clear that a CCCT is the resource of choice. Idaho Power is planning to
4 bring Langley Gulch on line in June 2012, with its next thermal unit being a combustion turbine in
5 2022 followed by a CCCT in 2025 .7 Avista purchased the output of the Lancaster combined-cycle
6 generating station through a tolling agreement in 2007 and while the Company's next CCCT is not
7 planned until 2023 there is a combustion turbine in their preferred strategy in 2018 .8 PacifiCorp has
8 a CCCT F Class scheduled to come on-line in 2014 and a CCCT H Class planned for 2010 For
9 the three investor-owned electric utilities in Idaho, as well as most of the rest of the country, a
10 CCCT is the resource of choice for base load plants for planning purposes and hence it remains the
11 reasonable choice for the proxy unit for the SAR.
12 Q. BEFORE YOU DISCUSS THE UTILITIES' RECOMMENDATIONS IN THIS
13 DOCKET WOULD YOU PLEASE DISCUSS SOME OF THE UNIQUE ASPECTS OF
14 AN ELECTRIC UTILITY'S AVOIDED OR MARGINAL COSTS AS ITS POWER
15 SYSTEM GROWS?
16 A. Yes. Due to required lead times, economies of scale, efficiency, etc., utilities tend to add
17 plant in relatively large increments. This means in actual practice, generation capacity is
18 periodically added in a "lumpy" fashion. Hence, at any given time, an actual system will have a

1 bit more, or a bit less, than the optimal amount of generating capacity. Because generating
2 resources tend to be added to actual systems in relatively large MW increments (e.g. 100 MW or
3 more), and even if units are carefully sized to correspond to the system size, and expected rate of
4 load growth, it is too much to expect the mix of different types of generating plants to be
5 precisely optimum.
6 As Commissions around the county were struggling with the implementation of PURPA,
7 NERA produced a series of publications that became known as the "Grey Books." Although
8 these Grey Books were published just prior to the passage of PURPA, commissions and utilities
9 around the country used them in implementing PURPA because they set forth the theoretical
10 basis for quantifying a utility's marginal costs. These "Grey" books provided much of the
11 theoretical background that was used in establishing avoided cost rates by regulatory
12 commissions. As explained by NERA in one of the "Grey Books", because capacity is added in
13 discrete blocks with long lead times, marginal costs fluctuate around the utilities long-run least
14 cost growth path.
15 Because of this fluctuation, in some years the short run operating costs may fall short of
16 what is needed to recover the total cost of building and operating a new generating unit - but in
17 other years, particularly just before the time when a new base load generating plant needs to be
18 added to the system, one would expect the marginal running costs of the system to be much
19 higher. This phenomenon is critical in defming avoided costs for a utility because of the way it
20 affects avoided or marginal costs in various time periods.
Reading DI
Clearwater, Simplot, Exergy
-10
Q. COULD YOU DESCRIBE WHAT YOU MEAN WHEN YOU STATE THAT
2 VARIOUS TIME PERIODS NEED TO BE CONSIDERED IN THE
3 DETERMINATION OF AVOIDED COST RATES?
4 Consideration of the time dimension in the consideration of marginal generating capacity
5 costs are outlined in the Topic 4 "Grey Book" referenced above. The publication discusses the
6 implications of using long-run and short-run marginal capacity costs
7 A. The long-run marginal generating capacity cost is the cost of the generating
8 unit that, in an optimal (least total cost generating mix) system, would be
9 added to accommodate increased peak-period demands. Depending upon the
10 utility's load duration curve and the natural resources available to the utility,
11 this unit will most likely be a combustion turbine, a pumped storage project, a
12 cycling (daily) fossil unit or an additional water wheel at an existing hydro
13 site.
14
15 B. The short-run marginal capacity cost will be the shortage cost for hours not
16 served. Theoretically, on an annual basis, if the expected shortage cost equals
17 or exceeds the cost of peaking capacity, system expansion will occur.
18
19 C. Due to the fact that capacity is acquired in discrete blocks and long lead times
20 are required, utilities will oscillate around the least total cost expansion curve.
21 Rather than follow the short-run costs in their oscillations around equilibrium,
22 it is recommended that, Lormarginal costing purposes, the long-run marginal
23 costs gf generating capacity be used except in chronic cases of imbalance.
24 (emphasis added)10
25
26 In practical terms what this means is, over time, a utility will in the normal course of
27 building plant to meet load almost always have surplus generating capacity. Because generation

plant will be added in chunks that will exceed its shorter-term load needs it will thus almost

1977).

-11
I always have a capacity surplus. Unless QFs are credited for long-run capacity costs they will
2 never by compensated on an equal basis relative to what the utilities receive in rates to build
3 plant.
4 Q. YOU HAVE STATED THE NEED FOR THE TIME DIMENSION TO BE
5 TAKEN INTO ACCOUNT IN THE DETERMINATION OF AVOIDED CAPACITY
6 RATES. IS THE SAME TRUE FOR DETERMINING AVOIDED ENERGY COSTS?
7 A. Yes. That same NERA Topic 4 "Grey Book" explains why the calculation of marginal
8 energy costs should also take into account the oscillations around a utility's least cost planning
9 path.
10 In the case of systems oscillating around an optimal generating mix equilibrium, it
11 is desirable to analyze marginal energy costs over a full cycle of oscillation,
12 usually five to ten years into the future. (emphasis added)"
13
14 Idaho Power's proposed method for determining avoided energy costs (discussed in more detail
15 below) uses a very short-run hourly marginal cost calculation.
16 Q. Are there times when the incremental cost calculated with Idaho Power's
17 proposed methodology goes to zero?
18 A. Yes, and this is not unrealistic. Considering the minimum load levels
19 established for the thermal generating resources, and the amount of non-
20 dispatchable QF generation on Idaho Power's system, there may be hours during
21 low load periods when Idaho Power's avoidable incremental costs are zero. In
22 fact, there could be times when Idaho Power's avoided incremental costs would
23 be negative. 12

1 Including these "avoidable incremental costs" as part of the calculation of avoided energy cost,
2 as in the case of avoided capacity costs described above, does not put the QF on an equal cost
3 footing with the utility's own resources. In any given hour the utility is incurring energy costs to
4 produce power to serve loads that are being passed on to customers. When the utility requests a
5 certificate from the Commission to build plant it includes its expected fuel costs for the plant at
6 an assumed capacity factor. What the utility does not do is add the plant to its resource stack and
7 then ask for recovery based on the highest cost resource it may be replacing on an hourly basis.
8 Q. EACH OF THE UTILITIES IN THIS DOCKET ARE ADVOCATING THAT QFs
9 SHOULD NOT BE ELIGIBLE FOR CAPACITY PAYMENTS WHEN THE UTILITY'S
10 FORECASTS DETERMINE THAT CAPACITY IS NOT NEEDED. GIVEN YOUR
11 EXPLANATION OF THE "LUMPY" NATURE OF A UTILITY'S INVESTMENTS, DO
12 YOU HAVE A POSITION ON THAT ISSUE?
13 A. Yes. As I have explained above, a utility will add plant in increments that will exceed its
14 short term needs to serve load. Therefore, unless due to some unforeseen factor or under-
15 forecasting, a utility will almost always be surplus for the next few years. As noted in Avista
16 witness Clint Kalich's Direct Testimony, the Commission explicitly dealt with first deficit year
17 or surplus period issue in Order 29124. In that Order the Commission concluded:
18 The continued importance of a first deficit year in avoided cost
19 calculations has to be weighed against the improbability of settling on a surplus
20 period in which anyone has confidence. Utilities have had the opportunity to
21 instill confidence in the first deficit year but in failing to update for changes in
22 load/resource balance have compromised the public confidence in the
23 reasonableness of its continued use. It is a factor in avoided cost calculation, the
Reading DI
Clearwater, Simplot, Exergy
-13
I Commission finds, that needs to be taken into account only to the extent
2 practicable. Reference 18 C.F.R. 292.304(e). The record supports a finding that
3 continued use of the first deficit year is administratively burdensome and no
4 longer practicable. ....We find it appropriate to create an avoided cost that
5 contains the full value for both energy and capacity. 13
6
7 The Commission also noted in that same Order that one of the intervenors, Plummer Forest
8 Products, offered a metaphor for a utility's surplus period:
9 It was also suggested by Plummer that it poses a "Catch 22" dilemma - i.e., a
10 utility only has to purchase if it's deficit; however, a utility can extend its surplus
11 by constructing its own resources, so a utility is never deficit and never has to
12 purchase. 14
13
14 A "Catch 22" dilemma is an apt phrase for the trap that a QF faces when it is denied capacity
15 payments when a utility claims it is in surplus. As pointed out above the denial of capacity
16 payments during a period of claimed surplus does not put a QF facility and a company owned
17 generating plant on an equal footing.
18 Q. IN HIS DIRECT TESTIMONY AVISTA'S WITNESS KALICH INDICATES
19 THINGS ARE DIFFERENT NOW THAN THEY WERE IN 2002 WHEN THE
20 COMMISSION ISSUED ORDER NO 29124 AND GOES ON TO REBUT THE NINE
21 REASONS OUTLINED BY STAFF FOR THE ELIMINATION OF THE DEFICIT
22 PERIOD. DO YOU HAVE ANY COMMENTS REGARDING MR. KALICH'S
23 TESTIMONY?

IPUC Order No. 29124, GNR-E-02-01 (2002).
14 Id..

I arguments do not justify eliminating capacity payments to a QF during surplus periods. I will
2 focus on three points; first his assumed definition of "true avoided cost," second the difference
3 between "surplus" energy rates and rates identified in an SAR, and third that the utilities' IRPs
4 are subject to "significant oversight."
5 Mr. Kalich addresses the point that utilities are likely to be surplus in the near term (point
6 7). Mr. Kalich States:
7 The seventh concern was that utilities tend to be surplus in the near term,
8 and that avoided cost rates should not provide incentives for a utility to increase
9 its length to avoid having to purchase PURPA power. It is often true that utilities
10 are surplus in early years; being so is an essential part of providing reliable utility
11 service. It also is true that QF developers would be affected by these surpluses
12 were they to receive lower early-year payments during surplus years. But this
13 effect is a reflection of true avoided costs. (emphasis added)15
14
15 Given the discussion above about "lumpy" utility investment, I certainly agree with the first part
16 of the above statement that utilities tend to be surplus in the near term. However, also as
17 discussed previously, I strongly disagree that QFs receiving lower early-year payments are a
18 reflection of "true avoided costs." Avista apparently believes "true avoided costs" means QFs
19 seldom are compensated for capacity payments for their facilities in the early years while the
20 Company's own generation plant receive recovery of full capacity for the full term of the plant
21 life.
22 Q. THE SIXTH CONCERN EXPRESSED BY STAFF WAS THAT THE
23 DIFFERENCE BETWEEN PURPA RATES AND "SURPLUS" ENERGY HAD
15 Direct Testimony of Avista Witness Clint Kalich, GNR-E-1 1-03, pp. 1 3-14.
Reading DI
Clearwater, Simplot, Exergy
-15
I NARROWED AND HENCE THERE WAS LESS JUSTIFICATION FOR
2 DISTINQUISHING THE DIFFERENCE. DO YOU AGREE WITH THAT
3 CHARACTERIZATION?
4 A. Yes and no. At this time there are significant differences between SAR set rates and the
5 surplus energy rates. However over the past 30 years that PURPA rates have been in place in
6 Idaho there have been periods where market rates have been both less than and greater than SAR
7 set rates. At this time, the price of natural gas tends to drive electric rates. While current gas
8 rates are very low, natural gas rates have tended to be extremely volatile over time and, as
9 pointed out above, avoided cost rates should reflect the long-run marginal costs for a utility.
10 Mr. Kalich believes this concern is made moot if his recommendation for bifurcating
11 energy and capacity payments to a QF is adopted. He proposes capacity payments for a QF
12 calculated on a per-MW "on-peak contribution" basis. Mr. Kalich's proposal seems to disregard

I A. I would agree if the utilities IRP's were, in fact, "subject to significant oversight" in their
2 development and submission. The Idaho Commission only accepts each utility's IRP for filing;
3 it does not approve the utility's conclusions. The following Commission statement is taken from
4 Idaho Power's 2011 IRP. It is typical for all Idaho IOUs:
5 Based on our review, we find it reasonable to accept for filing and to
6 acknowledge Idaho Power's 2011 Electric Integrated Resource Plan. Our
7 acceptance of the 2011 IRP should not be interpreted as an endorsement of any
8 particular element of the Plan, nor does it constitute approval of any resource
9 acquisition contained in the Plan. 17
10
11 It is significant that the Commission states it's acceptance for filing of the IRP does not
12 constitute approval of any resource acquisition nor even an endorsement of any particular
13 element in the plan. It is true the utilities have instituted a public process in the development of
14 their IRPs along with forming consumer advisory groups. However, an IRP contains a large
15 number of very complex and technical aspects that lay advisory groups do not have the time or
16 expertise to thoroughly critique.
17 Q. DR. READING, WHAT DO YOU RECOMMEND IN THE FUTURE FOR
18 DEVELOPMENT OF IRPs?
19 A. IRPs are becoming increasingly relied upon for a wide number of important regulatory
20 issues. These uses include justifying adding resources, establishing avoided costs, determining
21 periods of deficit and surplus, projecting load growth, and measuring cost effective DSM, etc.

I Given the importance of the IRP in justifying utility expenditures and its ultimate impact on
2 customer rates it is essential that the IRP be subject greater scrutiny and subjected to a litigated
3 hearing and ultimately approval by the Commission. Only after the IRP is subjected to thorough
4 examination should its various conclusions be accepted for rate setting purposes.
5 Q. HOW DOES AVISTA RECOMMEND CALCULATION OF CAPACITY COSTS?
6 A. As discussed in the last section, Avista's Mr. Kalich is recommending bifurcating energy
7 and capacity payments to QFs. He proposes capacity payments for a QF be calculated on a per-
8 MW "on-peak contribution" basis. This is accomplished by converting the SAR per MW1I
9 payment level to a total annual capacity payment that is divided by the expected annual capacity
10 factor. For PURPA projects eligible for published avoided cost rates, rather than using capacity
11 based on the SAR, he advocates calculating capacity payments based on the nature of the project.
12 In addition he recommends these separate capacity amounts based on the type of project be
13 calculated on a per MW basis and then "translated" to a dollars per MWh that is added to the per
14 MWh energy rate to determine avoided cost. He also asks that once the SAR capacity payment is
15 calculated it serve as a cap on total payments for any given year to prevent a QF from
16 underestimating its energy output.
17 Q. DO YOU AGREE WITH THESE CHANGES AVISTA IS ADVOCATING FOR
18 THE CALCULATION OF CAPACITY PAYMENT FOR QFs ELIGIBLE FOR
19 PUBLISHED RATES?
Reading DI
Clearwater, Simplot, Exergy
-18
I A. The process adds unneeded and unnecessary complexity to the calculation of avoided
2 costs for published rates. As pointed out above, especially for smaller QFs eligible for published
3 rates the computing of avoided costs should be as simple and straight forward as possible. It
4 should be transparent and understandable. In my opinion, he is solving problems that do not
5 exist.
6 Q. DO YOU AGREE WITH ANY OF MR. KALICH'S RECOMMENDATIONS?
7 A. I agree with his recommendation that the Commission should use the regularly updated
8 gas forecast generated by the Energy Information Administration (EIA) in its Annual Outlook
9 Report as the forecast by which the Commission updates the published gas SAR avoided cost
10 rates. 18 The Commission currently uses the irregularly published gas forecast generated by the
11 Northwest Power and Conservation Council.
12 Although the Northwest Power and Conservation Council's forecast can provide a stable
13 rate for QFs, it can be difficult for QFs to know when to expect the rates to go up or down. I
14 believe all parties, including QFs, the Commission, and the utilities, could benefit from a
15 predictable rate change at a predetermined date each year occurring within a reasonable time
16 period of the regularly released EIA Outlook Report. The full report appears to be released in
17 the spring. I recommend that the Commission clearly state that the rates each year will be
18 updated on a specific date each year, such as on June 1, whether the rates are going up or down.
19 I believe this recommendation addresses the utilities' concern that the existing gas price updates

2 II. NON-STANDARD RATES FOR QFs ABOVE THE ELIGIBILITY CAP
3 Q. THE THREE IDAHO IOUs IN THIS DOCKET HAVE FILED WHAT THEY
4 CHARACTERIZE AS THE COMMISSION APPROVED "IRP METHODOLOGY" FOR
5 THE DETERMINATOIN OF AVOIDED COST RATES. WOULD YOU PLEASE
6 DISCUSS THE APPROACH EACH UTILITY HAS RECOMMENDED TO THE
7 COMMISSION FOR APROVAL?
8 A. I examined the three proposals and compared them against the Commission Staffs "IRP
9 Methodology" for determining a utility's avoided cost for PURPA projects in Idaho that the
10 Commission approved in Case No IPC-E-95-09 The methods put forth by the utilities vary
11 significantly. RMP follows the approved methodology fairly closely. Idaho Power, however,
12 takes an entirely different approach.
13 Q. WOULD YOU PLEASE EXPLAIN IN MORE DETAIL WHAT YOU MEAN
14 WHEN YOU STATE THAT THE APPROVED IRP METHODOLOGY IS NOT BEING
15 FOLLOWD BY ALL OF THE UTILITIES?
16 A. Before analyzing each of the utilities' proposals, an examination of the generally
17 accepted approaches to calculating avoided costs needs to be considered. Idaho Power witness
18 William Hieronymus in this direct testimony reviews what he refers to as the taxonomy of
19 administrative methods for setting avoided costs as set forth in a report by the Edison Electric
Reading DI
Clearwater, Simplot, Exergy
-20
1 Institute (EEl) that examined the setting of avoided costs. 19 The paper was prepared by the
2 Brattle Group. The three methods found in the EEl paper also match those found in the survey
3 by NERA discussed above.
4 Q. COULD YOU PLEASE BRIEFLY DESCRIBE THESE THREE METHODS
5 THAT HAVE BEEN USED BY REGULATORY COMMISSIONS IN THE
6 DETERMINATION OF AVOIDED COST RATES FOR PURPA PROJECTS?
7 A. State public utility commissions have used three basic approaches for determining
8 avoided costs since the enactment of PURPA in 1978. Various states have employed various
9 incarnations of these three basic approaches, as pointed out in the NERA survey for finding
10 avoided costs for utilities under their jurisdiction. The three methods are: 1) the Peaker Method,
11 2) the Proxy Method, and the 3) Differential Revenue Requirement Method.
12 Q. WOULD YOU PLEASE DESCRIBE THE PEAKER METHOD?
13 A. Yes. When using the Peaker Method, the utility's power supply model is run with and
14 without the given facility, at zero cost, to produce variable costs. Then, the capital costs of a
15 peaking unit on a MWh basis is added to variable costs to find a utility's avoided costs.
16 Q. WHAT IS THE PROXY METHOD?
17 A. Under the Proxy Method (which is currently used in Idaho for published rates), the
18 capital costs of the proxy unit are included, along with operation and maintenance expenses
19 including fuel, as part of the calculations to find the utility's avoided cost. The assumption is

Reading DI

-21
I these calculated costs are a "proxy" for what the utility would incur to build the unit and
2 therefore are a reasonable estimate of its avoided cost.
3 Q. THE THIRD APPROACH YOU MENTIONED IS THE DIFFERENTIAL
4 REVENUE REQUIREMENT METHOD. WOULD YOU PLEASE EXPLAIN THIS
5 METHOD?
6 A. Yes. The Differential Revenue Requirement Method calculates the utility's total
7 generation costs (or revenue requirement) with, and without, the proposed facility. This method
8 first uses an expansion plan model to generate expansion plans with and without the proposed
9 facility. The method then uses the two different expansion plans as inputs to a financial planning
10 model to produce the utility's revenue requirement with and without the proposed facility's
11 output provided as free energy. That financial model would include items such as interest costs,
12 taxes, allowed rate of return on the change in rate base and capital and other "rate case" inputs
13 for the facility. The difference in the present value of the revenue requirement is the avoided
14 revenue requirement component and is, in theory, the utility's full avoided cost, including
15 avoided energy and capacity costs, as well as taxes and other cost factors.
16 The Commission accepted the Differential Revenue Requirement Method for finding
17 avoided cost rates for QFs larger than 1 MW in Case No. IPC-E-95-9. The Commission
18 approved a stipulation in that case that was signed by the three utilities, Commission Staff, and
19 Rosebud Enterprises, Inc. Other parties in that docket chose not to sign the stipulation, but they
20 did not oppose the methodology. Attached to Commission Staff witness Sterling's Direct
Reading DI
Clearwater, Simplot, Exergy
-22
1 Testimony filed in that case is Exhibit 101 that contains Staffs proposed avoided cost
2 methodology that was accepted by the Commission. This is the approach that is being commonly
3 referred to as the "IRP Methodology" for Idaho utilities.
4 Q. WHY DO YOU SAY THE DIFFERENTIAL REVENUE REQUIREMENT
5 METHOD IS ESSENTIALLY THE METHOD APPROVED BY THE COMMISSION IN
6 CASE NO. IPC-E-95-09?
7 A. The essence of Staffs methodology is employing the Differential Revenue Requirement
Method described above comparing the present value of the revenue requirements (PVRR) of the
base case with one that includes the utility's system including the QF. Items 6 and 7 of the
Stipulation state:
6.Finally, the present value of the QF project avoided cost is calculated by
subtracting the PVRR of the modified plan, with the costs of the QF set
to zero, from the PVRR of the base case resource plan.
7.Rates for capacity and energy from the QF project can then be developed for
which, on a present value basis, the expected payments to the QF are equal to the
project's avoided cost over the life of the contract .20
Note that item 7 states that the avoided cost rate for a QF is found by using both capacity and
energy. The end result is that Idaho has two methods for calculating avoided costs, the Proxy
method for smaller projects, and the Differential Revenue Requirement Method for larger
projects

I Q. COULD YOU REVIEW THE "IRP METHOD" PROPOSED BY EACH IOU IN
2 THIS DOCKET?
3 A. Rocky Mountain Power appears to follow differential revenue requirement method
4 proposed by Staff and approved by the Commission. RMP Company witness Kelcey Brown, in
5 describing that Company's approach, first reviews the seven steps outlined in Staff's "IRP
6 Methodology" and then outlines how the Company follows each of those steps .
21 For the energy
7 component of avoided costs, the Company uses a "GRID" model for two simulations. One using
8 the preferred portfolio, and the second for the QF at no cost that finds the PVRR and then
9 calculates the difference between the two.
10 Q. HOW DOES RMP FIND THE CAPACITY COMPONENT OF AVOIDED
11 COSTS?
12 A. To calculate the capacity component of avoided costs, Rocky Mountain Power first
13 determines the level of deferrable capacity measured by the next deferrable CCCT found in its
14 latest IRP, plus the impact of capacity from the requesting QF. Also, when a QF makes a request
15 for avoided cost prices the Company updates the GRID with its latest forecasts for a set of
16 variables they assume have changed since the IRP was filed. According to Ms. Brown:
17 The Company updates the GRID model based on the most recently available
18 information each time a QF requests avoided cost pricing. This includes updates
19 related to new contracts, fuel prices, forward price curves, load forecasts and
20 other assumptions. However, the underlying IRP preferred portfolio does not
21 change and is consistent with the most recently filed RP.22

2 This means the price offered to the QF is calculated on a different basis than what the
3 utility used in the development of their preferred portfolio in their IRP -- which is used to justify
4 the construction of their own resources among other things. In addition, this means the QF
5 requesting a price has the burden of vetting RIvIP's latest view of loads, fuel prices, and other
6 variables. These "updated" variables have not had even a cursory review by the Commission or
7 stakeholders as have these inputs found in the IRP. In addition, because the outputs of the GRID
8 model run for QFs are being subtracted from the base case with different underlying input
9 assumptions, the results are confounded by whatever changes in these variables the utility
10 assumes have occurred. As discussed above, the IRP's need greater scrutiny if they are to be
11 used for the calculation of avoided cost rates, these unilateral interim adjustments are a step
12 further away from the vetting process and should not be allowed.
13 Q. DR. READING, WOULD YOU PLEASE COMMENT ON AVISTA'S APROACH
14 TO THE CALCULATION OF AVOIDED COSTS?
15 A. According to Avista's response to a production request, under the IRP Methodology,
16 assumptions are first reviewed and updated where appropriate (e.g., natural gas, loads and
17 resources). Where assumptions affecting the wholesale marketplace have changed (e.g., natural
18 gas prices) the AURORA IRP model is re-run and Avista's PRiSM model is updated with the
19 new wholesale market data (i.e., value of the new generation resource options). The Company
Reading DI
Clearwater, Simplot, Exergy
-25
I then produces two new PRiSM runs to determine capacity and energy values. In the first new
2 PRiSM run, the capacity component of the QF resource is added to the load and resource
3 tabulation (L&R). The difference between the two economic values (i.e., revenue requirement
4 between the pre-QF PRiSM run and PRISM run containing the QF capacity) determines the
5 avoided capacity value available for the QF contract. A second PRiSM run is then performed
6 where both the expected capacity and energy contributions of the QF resource are added to loads
7 and resources. The difference between the first PRISM run and the second PRiSM run
8 determines the energy payments available to the QF contract.
9 This procedure is somewhat similar to that used by RMP. Loads, natural gas prices, etc.
10 are updated, the QF capacity is added to the resources of the utility and the difference between
11 two PRiSM runs, one with and one without the QF, is calculated to find the avoided cost of
12 energy. As discussed above the input variables that are updated from the IRP by the utility are
13 not subject to any regulatory or stakeholder review and therefore should not be allowed to be
14 used in the calculation of avoided energy costs.
15 Q. AVISTA IS RECOMMENDING ONE OF THOSE INPUT VARIABLES,
16 NATURAL GAS PRICE, BE UPDATED ANNUALLY FROM RATES PUBLISHED BY
17 THE ENERGY INFORMATION ADMINSTRATION (EIA) IN ITS ANNUAL ENERGY
18 REVIEW. DO YOU AGREE WITH THIS RECOMMENDATION?
19 A. Yes, because this gas forecast is published by a neutral source on an annual basis and
20 because it is assessable and transparent for all parties. Therefore, for this input from this source it
Reading DI
Clearwater, Simplot, Exergy
-26
I is reasonable to change natural gas prices between the utilities' IRPs. This is consistent with my
2 agreement discussed above with Mr. Kalich's recommendation to use the EIA forecast to
3 annually update published rates in the SAR. Other third party transparent sources for natural gas
4 prices could also be acceptable, so long as a predetermined date is set by the Commission for the
5 update to allow for parity in input changes that will result in rate increases and rate decreases.
6 Q. COULD YOU NOW DESCRIBE HOW IDAHO POWER IMPLEMENTS THE
7 "IRIP METHOD" APPROACH APPROVED BY THE COMMISSION?
8 A. Yes. Idaho Power recommends abandoning the Commission approved method entirely.
9 It is recommending a peaker method (although it is still being called a modified "IRP
10 Methodology"). The Company is recommending the use of a SCCT rather than a CCCT. In
11 addition, it has abandoned the two model run approach (one with and one without the QF
12 requesting avoided cost pricing), for a single model run method that attempts to replicate the
13 Company's operation of its resource stack during each hour for all hours of the QFs contract
14 term.
15 Q. COULD YOU PLEASE EXPLAIN IN GREATER DETAIL HOW IDAHO
16 POWER PROPOSES TO DETERMINE THE AVOIDED COST OF ENERGY THAT
17 WILL BE OFFERED TO A QF?
18 A. Idaho Power is proposing a single run of the AROURA model that calculates avoided
19 energy costs equal to the cost of the Company's most expensive unit forecasted to be on-line for
20 each hour of the year for the contract term. As discussed in the last section, this is estimating
Reading DI
Clearwater, Simplot, Exergy
-27
I avoided cost on a jLea short-run hourly basis. According to the direct testimony of Company
2 witness Karl Bokenkamp:
3 Once the highest displaceable incremental cost is identified for a given hour, any amount
4 of displacement available from that resource (generator, longer-term firm purchase or
5 market purchase) sets the incremental cost for that hour regardless of the volume actually
6 available to be displaceable; e. g., if there are no purchases, and all thermal plants are
7 either off or at their minimums except for one Bridger unit which is at 10 MW above
8 minimum and its incremental cost is $17 /MWh even if the "new" QF that the analysis is
9 being run for is expected to produce 20 MW during that hour. This simplification may
10 introduce some error, but it will always be in favor of the QF since Idaho Power begins
11 with the highest incremental cost resource that is displaceable to set the avoided cost for
12 any hour.23
13
14 However Idaho Power makes another "simplification." This "simplification" of the model run
15 assumes that each of the Company's thermal units has a heat rate equal to its full load operation:
During many hours of the year, Idaho Power's highest displaceable incremental cost will
be set by one of its thermal resources. And because a thermal plant's heat rate changes
with load, the incremental costs also change with load. However, to simplify the analysis,
Idaho Power proposes use of the following assumptions:
1. Each thermal unit is assigned one incremental cost, which will be based on full load
operation, which applies all year long regardless of the loading level determined in the
AURORA analysis[.] (emphasis added)24
The problem with this approach, as Mr. Bokenkamp points out, is that heat rates change as
thermal units are ramped up and down. As the generating unit is backed down to follow load its
heat rate goes up and its efficiency goes down. Therefore, the cost per MWh of output goes up.
Assuming all units in the Company's resource stack are operating at full load, reduces the

1 avoided cost assumption from how the Company actually operates. According to a Response to a
2 Production Request the $/MWh difference in incremental energy cost between maximum and
3 minimum load for a unit can be as much as 20%.25 This process results in an unrealistically low
4 avoided cost rate. In addition, the incremental cost for each thermal unit is updated each year
5 based on the fuel forecasts which, as discussed above, are not subject to any analysis other than
6 the Company's own estimates.
7 Q. WHAT CONCLUSIONS CAN YOU DRAW FROM YOUR ANALYSIS OF
8 IDAHO POWER'S APPROACH TO CALCULATING AVOIDED ENERGY COSTS
9 THAT WILL BE OFFERED TO A QF?
10 A. Idaho Power's approach is fatally flawed. As pointed out above, the approach incorrectly
11 assumes avoided costs should be based on a M short-run hourly basis. The Company also
12 makes additional "simplifying" assumptions that lower the price that will be offered to a QF. It
13 certainly does not put a PIIRPA project and the Company's own resources on an equal cost
14 basis. The Company does not, when it wants to build one of its own resources, add that resource
15 to its AURORA model runs, and then ask the Commission for recovery based only on the value
16 of the highest cost resource in the stack in every given hour over the life of the plant. What the
17 Company does is estimate the costs of the resource at a given capacity factor -- which closely
18 approximates the SAR method currently in place.

1 Q. HOW DOES IDAHO POWER RECOMMEND CAPACITY COSTS BE
2 CALCULATED?
3 A. According to the testimony of the Company's witness:
4 The proposed modifications to the IRP-based methodology produce a
5 lower avoided cost of energy for each project. This is expected because the
6 proposed modifications (which are based on identifying the incremental costs to
7 the utility for energy or capacity which, but for the QF purchase, the utility would
8 generate itself or purchase) produce an avoided cost that is based on the
9 incremental cost avoided by displacing one of Idaho Power's thermal generating
10 resources, or avoiding a market purchase. This is in contrast to the current
11 implementation of the IRP methodology which uses the QF output to support
12 market sales or displace purchases which results in a market-based valuation as
13 opposed to a valuation based upon the definition of avoided cost.
14 The proposed modification to the type of resource used in the avoided cost
15 of capacity calculation results in an avoided cost of capacity that is about 55
16 percent of that produced by using a CCCT. This is also expected because the
17 capital costs of a SCCT are quite a bit less than the capital costs of a CCCT. The
18 total investment costs for a SCCT and CCCT as identified in Idaho Power's 2011
19 IRP are $790/KW and $1,380/kW, respectively.26
20
21 As pointed out above, the Company is proposing to use the "peaker method" in the calculation of
22 avoided costs to be offered to QFs. It should be pointed out once a utility is allowed to put one of
23 their own resources in rate base it will receive full recovery of the capital cost irrespective of
24 whether or not the unit runs. The Company also expresses concerns that ratepayers will get stuck
25 with a PURPA project for a 20 year period without acknowledging that once one of their own

1 plants is placed in rate base that ratepayers will pay the for the capital costs of the facility even if
2 the plant is seldom run.
3 Q. DR READING DO YOU HAVE ANY CONCLUDING REMARKS ABOUT THE
4 AVOIDED COST PROPOSALS AND THE UTILITIES' "IRP METHODOLOGY" VS
5 THE SAR METHODOLOGY?
6 A. Yes. All accepted methods (as described above) for calculating avoided costs have pluses
7 and minuses. One of the major pluses for the SAR method is its simplicity and transparent
8 nature. Idaho Power's witness Hieronymus's direct testimony references a report by Ms. Carolyn
9 Elefant. In that report she lists the "Pros" and "Cons" of the various avoided cost methodologies.
10 The "Pro" for the Proxy Method is that it is "Simple and transparent. ,27
11 One of the problems with what each of the utilities is proposing is that each company
12 uses different models, each of which has thousands of input assumptions and algorithms that
13 neither a requesting QF nor the Commission have the resources to examine thoroughly. On the
14 other hand the SAR methodology has few enough variables that the parties and Commission
15 Staff can analyze and present their case to the Commission as to the reasonableness of the
16 utility's assumptions. The proposals offered by the IOUs put the utilities in the driver's seat for
17 the determination of avoided cost rates offered to potential PURPA projects. Added to this
18 complexity, is the number of variables the utilities propose to make between IRP's (as discussed

1 above) that are changed at the discretion of the utilities and not properly vetted by the
2 Commission or the parties.
3 Q. DR. READING HAVE YOU LOOKED AT THE RATE IMPACT FOR VARIOUS
4 TYPES OF PROJECTS USING THE PROPOSALS BY THE UTILITIES IN THIS
5 DOCKET?
6 A. Yes. For all types of QF projects modeled for all three utilities the proposed methods
7 have the effect of significantly lowering avoided cost rates from the current posted rates. One of
8 more curious aspects of the utilities' approach is that their proposed avoided cost rates from their
9 "IRP Method" are significantly lower than the costs of building the utilities' own resources, as
10 well as, the costs presented in their recently filed IRPs. This result should not be a surprising
11 given the above discussion about how their proposed method measures only short-run avoided
12 costs and contain updated lower natural gas prices and loads. What is obvious in comparing these
13 rates is that the utilities want to offer QFs significantly lower rates than what they think it costs
14 to build their own generating capacity. These comparisons clearly point out the fallacies in their
15 approach and show the difference between the "avoided costs" of their own resources and what
16 they claim is fair to offer a QF.
17 Q. COULD YOU BE MORE SPECIFIC AND DEMONSTRATE WHAT YOU MEAN
18 WHEN YOU SAY AVOIDED COSTS ARE SIGNIFICANTLY DIFFERENT BETWEEN
19 WHAT THE UTILITIES BELIEVE IT COSTS THEM TO BUILD A RESOURCE AND
20 THE AVOIDED COSTS PROPOSED TO BE OFFERED TO QFs?
Reading DI
Clearwater, Simplot, Exergy
-32
I A. I will look at each utility in turn, and start with Idaho Power's calculations. The
2 Company has developed its avoided costs estimates for four hypothetical QFs each with a
3 different motive force. The four types are Baseload, Canal-drop Hydro, Fixed PV, and Wind.
4 The following four Charts depicts each of these four types with the levelized 20 year MWh costs
5 calculated by Idaho Power based on $/MWh basis. The comparison costs in $IMWh for each
6 type are based on the Company's 2011 IRP that was officially noticed by the Commission in
7 December 2011, along with the current and proposed IRP Method avoided cost calculations. For
8 Baseload comparisons Langley-Gulch values are included based on cost estimates filed by
9 Commission Staff.
10 As can be seen in the following Chart 1, the costs vary between a high of $111.13 per
11 $/MWh for Langley Gulch to a low of $47.40 per $/MWh for the Company's proposed IRP
12 Method. Langley Gulch is included in the baseload comparisons because it is entering the
13 Company's resource stack in June of this year. From a theoretical basis, it can be argued that
14 either the next or last generation plant is an accurate measure of the utility's marginal costs.

2 While it might be argued each of four cost estimates are not precisely comparable, the
3 order of magnitude of the difference between the utility's baseload load plant currently coming
4 on line, and what it proposes to offer a baseload QFs, is so dramatically different it calls into
5 question the claims that the proposed method is a realistic estimate of the Company's avoided
6 cost. It is also important to note all four of these estimates can be considered falling within the
7 same time frame and are therefore comparable.

2 With the exception of Hydro at $114.48 per MWh the highest proposed avoided cost offered is
3 $75.30 per MWh for Solar with the lowest being $42.51 for Wind.29 A similar comparison for
4 Rocky Mountain Power could not be made because matching the resource types between the
5 avoided costs presented in the Company's testimony and its latest IRP did not match up well.
6 However, a general comparison between the five hypothetical types are significantly lower than
7 those numerous resource types presented in RrvlP' s latest IRP.3° These divergent prices again
8 demonstrate that prices offered to QFs do not match what the utility believes it would cost to
9 build the type of resource and hence is not reasonable to be used as an accurate estimate of
10 avoided cost.
11 Q. COULD YOU SUMMERIZE YOUR RECOMMENDITIONS BASED ON THE
12 DISCUSSION ABOVE?
13 A. Published rates should be available for all types of QF projects less than 10 aMW based
14 on the SAR method. I do support Avista's proposal to update published rates utilizing the gas
15 SAR utilizing the EIA's Annual Outlook Report, provided that the Commission sets a
16 predetermined date applicable for the rate change. For projects over 10 aMW, what is called the
17 "IRP Method" should be used only when each utility's IRP is filly considered and approved
18 through the hearing process. Changes to variable inputs in the IRP Methodology should not be

I allowed between approved IRP's with the exception of natural gas prices based on EIA's annual
2 updates or from another publicly available third party source on a predetermined date. The
3 single model run approach advocated by Idaho Power should be rejected, and the models should
4 instead be run twice - once with the QF at zero cost and once without the QF. QF projects
5 should be eligible for capacity payments for the full term of their contract with no deficit period
6 allowed, and a 20 year contract term should remain the standard which is discussed further

9 PART 2: OTHER QF ISSUES
10 I. LIQUIDATED DAMAGES AND DELAY SECURITY
11 Q. AVISTA COMPANY WITNESS CLINT KALICH STATES QF CONTRACTS
12 SHOULD CONTAIN A PROVISION WITH "MEANINGFUL" DELAY DEFAULT
13 LIQUIDATED DAMAGES IN HIS DIRECT TESTIMONY. DO YOU HAVE ANY
14 COMMENTS ON HIS DISCUSSION ON PAGES 31 THROUGH 33?
15 A. Yes. In addition to my comments, I have also included discovery responses by Avista
16 addressing this issue as Exhibit 503 to my testimony. "Meaningful" of course is another term
17 that is in the eyes of the beholder. Mr. Kalich recommends the Commission authorize utilities to
18 require QFs to post a security deposit equivalent to $45 per kilowatt of nameplate capacity, and
19 allow the utility to terminate the contract and keep the $45 per kilowatt deposit if the actual on

-36
1 line date is more than 180 days beyond that stated in the contract.31 The rationale for the 180
2 day termination condition is the Company fears a developer may simply hold off bringing the
3 project on line if prices are falling and waiting for prices to hopefully increase. Mr. Kalich
4 supports the security provision because it creates a meaningful deterrent to delay in achieving the
5 proposed on line date. There are two major issues with what Avista (or any other utility) is
6 proposing for liquidated damages for a QF.
7 Q. WHAT IS THE FIRST ISSUE?
8 A. The first issue is that no Idaho utility has provided the Commission with any analysis on
9 a utility's likely actual damages in the event that a PURPA project either did not come on line at
10 the stated contract date or failed to come on line completely. Instead, the $45 per kilowatt delay
11 security amount appears to be an amount that the utilities have decided will provide adequate
12 deterrent to a breach. Avista simply conducted a survey of what other utilities have been able to
13 demand as a delay security in PPAs with independent power developers and states it has not
14 estimated the likely costs to Avista or any other utility should a QF default. 32 This is out of line
15 with Commission orders, which I presume are based upon the Commission's understanding of
16 Idaho contact law.
17 With regard to a recent contract containing a delay liquidated damage security, the
18 Commission stated "the Commission is concerned that such provisions will have a potentially
19 deleterious effect upon future PURPA projects. Quite often, operators of qualified small power

-37
1 production facilities do not have ready access to the necessary amount of security or capital
2 delineated in this Agreement." 33 The Commission declared:
3 Therefore, the Commission finds that such provisions calling for delay security
4 should not be punitive in nature. Rather, the amount of delay security ultimately provided
5 in this case, as well as future energy sales agreements with other PURPA suppliers,
6 should constitute a fair and reasonable offset of a regulated utility's estimated increase in
7 power supply costs attributable to the PURPA supplier's failure to meet its contractually
8 scheduled operation date. '
9
10 In other words, a liquidated damages provision should not operate merely as a one-way penalty
11 to deter one party from breaching the agreement. It should not be derived from a canvassing of
12 terms required by other utility purchasers because the traditional utility market is essentially a
13 monopsony market with only very limited number of purchasers in the region of any independent
14 power project. Standard terms in such a monopsony market place should not be assumed to be
15 fair. Instead, the liquidated damage provision should be an actual estimate of the likely damages
16 the non-breaching party (here, the utility) would incur. The intent should be to keep the utility
17 and its customer's whole in the event of a default. Otherwise, the provision is simply a penalty
18 provision unilaterally imposed by the party with superior bargaining strength. Avista has
19 admitted that it has made no effort to approximate its likely actual damages in the event of a QF
20 delay default. 35

-38
1 EVENT OF A QF'S DELAY DEFAULT?
2 A. One easy way to estimate a purchasing utility's actual damages in the event of a QF delay
3 default is to require the QF to pay the difference between the rate the utility would pay in the QF
4 contract and the actual cost for replacement power during the period the QF's delay default
5 forces the utility to secure replacement power. The replacement price would include the cost at
6 the relevant market hub plus the necessary transmission and administrative costs to secure that
7 replacement power. The period during which the utility would need to secure replacement
8 power should not last for the entire term of the power purchase agreement, which could be up to
9 twenty years, because the utility could obviously make alterative arrangements to meet its load
10 needs prior to the expiration of the 20-year contract term. The period during which the
11 breaching QF should be liable should be limited to a reasonable amount of time for the utility to
12 make alternative long-term arrangements to secure that amount of power. I understand that
13 Idaho QF power purchase agreements have in the past contained provisions tied to the
14 replacement price of electricity and capacity. The market price for replacement power in the
15 event of a QF default is quite low at the present time, and $45 per kilowatt is an excessive
16 amount for a QF to automatically forfeit in the event of a delay. For example, at $45 per
17 kilowatt, a 10 MW QF must provide $450,000 to the utility at the time the contract is approved.
18 Under Mr. Kalich's proposal, the utility would receive $450,000 for a 180 day delay in a QF's
19 achievement of its committed on line date. This appears far in excess of the utility's actual cost
20 for replacement power at the present time.
Reading DI
Clearwater, Simplot, Exergy
-39
I It is only in the last few years that the utilities began unilaterally imposing the $45 per
2 kilowatt delay security liquidated damages provision for QF contracts. Although I am aware of
3 complaint cases where QFs have alleged that a $45 per kilowatt delay damage provision is
4 unfair, I am not aware of any QFs having fully litigating such a complaint at the Commission. 36
5 The Commission should not consider the absence of a fully litigated challenge to be
6 representative of a belief that these clauses are a fair estimation of the utility's actual damages, as
7 required by the Commission order cited above. Even for a QF with the financial resources to
8 litigate the legality of the clause, a delay caused by filing a complaint at the Commission could
9 compromise the viability of the entire project because the timing of tax credits, financing and
10 equipment supplies are critical in development of a generation project.
11 Mr. Kalich even recommends requiring the $45 per kilowatt security amount be provided
12 by the QF simply to exercise the QF's right to create a legally enforceable obligation, i.e. a
13 binding contract that would lock in the fixed avoided cost rates. Many QFs cannot secure
14 financing and access to such large amounts of money until after the PPA is signed and approved
15 by the Commission. Thus, Mr. Kalich's proposal would create a timing problem for many QFs,
16 and would obviously be a substantial hurdle for all but the most well-funded QFs.
17 For all of these reasons, if such a requirement is to be authorized by the Commission, it
18 should not be based on a flawed method of calculating the utility's actual damages, so as to
19 unnecessarily deter otherwise viable QF projects. The Commission should take the opportunity
36 See IPUC Case Nos. IPC-E-1O-29 and -30; PAC-E-10-05.
Reading DI

-40
1 in this case to require the utilities to tie the delay default provision to a utility's actual damages.,
2 Q. WHAT IS THE SECOND ISSUE YOU WOULD LIKE TO MENTION WITH
3 DELAY SECURITY AND LIQUIDATED DAMAGES PROVISIONS?
4 A. Mr. Kalich notes in his testimony that the Company wants to "ensure a level playing
5 field" between the QF and the utility. 37 A true level playing field would be where the utility-
6 owned plants must be held to the same standard and issue rate payer refunds when their own
7 plants experience failures or delays. A good example is Avista's Reardan wind project that was
8 in the utility's Preferred Resource Strategy in its 2009 IRP. It was slated to come on line in 2010
9 or 2011, but now is not scheduled until 2014 or beyond. This is not to say that Avista
10 necessarily acted irrationally to replace this project with the Palouse wind RFP. I simply intend
11 to point out that utilities regularly incur expenditures for generation plants that either never come
12 on line or are delayed. If there are real costs to a utility and its customers that warrant a delay
13 default provision in a QF PPA, then there should likewise be compensation to the utility's
14 customers for a similar delay occurring at a utility-owned generation project. Avista's proposal
15 provides for unfair treatment to QFs and deprives the utilities' customers of a comparable market
16 check to the utilities' proposals to build their own generation resources.
17 Q. IS THERE ANYTHING ELSE THAT WOULD LEVEL THE PLAYING FIELD?
18 A. Yes, Mr. Kalich proposes only a provision that would address a default by the QF. But
19 there is the possibility that the QF could be harmed by a utility under certain circumstances, and
Direct Testimony of Avista Witness Clint Kalich, GNR-E-11 -03, p. 33.
Reading DI
Clearwater, Simplot, Exergy
-41
1 therefore QF contracts should provide for compensation to the QF in the event of a utility
2 default. For example, a delay in achieving an on line date could occur solely because the utility
3 failed to complete interconnection construction as scheduled. The QF could be damaged by such
4 a delay because it could delay the project's schedule and the time by which the project would
5 start generating revenue. Such a delay by the utility in completing interconnection should not
6 result in the QF being in default on its power purchase agreement. Another potential cause of
7 damage to a QF is if the utility experiences a disruption on its system that requires curtailment of
8 the QF for a lengthy period of time. The QF should be compensated for the lost revenue and
9 other damages it might incur by the unscheduled outage. Further, as I will discuss below, Idaho
10 Power's proposed Schedule 74 curtailment provision would allow Idaho Power to curtail QFs
11 under certain circumstances. But Idaho Power's provision provides no express remedy to QFs if
12 Idaho Power implements the curtailment at an inappropriate time or in a manner that harms the
13 QF.
14 If Idaho QF PPAs will include damage provisions, they should address the possible
15 damages to the QFs also, not just the potential damages to the utilities.
16 II. AVISTA'S PROPOSAL THAT QFs MUST ACHIEVE ON LINE STATUS
17 WITHIN 2 YEARS TO OBTAIN FIXED RATES.
18 Q. DO YOU HAVE ANY COMMENTS ON AVISTA COMPANY WITNESS
19 KALICH'S RECOMMENDATION THAT QF CONTRACTS NOT BE SIGNED
20 EARLIER THAN FIVE YEARS BEFORE COMMERCIAL OPERATION AND THAT
Reading DI
Clearwater, Simplot, Exergy
-42
I FIXED PRICES SHOULD BE MADE AVAILABLE NO EARLIER THAN TWO YEARS
2 BEFORE COMMERCIAL OPERATION?
3 A. Yes. A QF that is building a new project will need to secure financing before
4 commencing construction. A bank or lender is unlikely to agree to provide the money to build
5 the project until there is a guaranteed revenue stream if the project is successfully built. Mr.
6 Kalich's proposal essentially would give a new QF a maximum of two years after signing the
7 PPA within which to secure financing, and achieve on line status. For many types of generation
8 projects, it could take much longer than two years to complete construction alone. Mr. Kalich's
9 testimony contains no analysis of the impact of this 2-year requirement on a party attempting to
10 build a generation project. If adopted, the requirement would certainly deter some QF projects.
11 Q. WHAT IS MR. KALICH'S REASONING FOR THIS 2-YEAR REQUIREMENT?
12 A. Mr. Kalich states: "Too many things affecting price can change over a five-year term,
13 both for the QF developer and the utility."38 Apparently, Avista's concern is that the avoided
14 costs may decrease between the time of contract execution and the time the QF project is built.
15 This is another example of the utilities attempting to require QFs to provide greater assurances to
16 ratepayers than the utilities themselves would ever agree to provide.
17 Q. PLEASE EXPLAIN.
18 A. While the Company recommends this 2-year condition for a QF, the condition is
19 demonstrably inapplicable for a utility-built plant. Idaho Power received its CPCN with the
38 Direct Testimony of Avista Witness Clint Kalich, GNR-E- 11-03, p. 31.

I costs approved for Langley Gulch in September of 2009 but will not be on line until June of
2 2012. It is interesting to apply both Mr. Kalich's delay security provision proposal and his 2-
3 year on line status proposal to the Langley Gulch plant. For Langley Gulch to receive
4 guaranteed fixed rates, Mr. Kalich's proposal would require it to provide a guaranteed on line
5 date within two years of September 2009 when the Commission issued the CPCN. To obtain
6 guaranteed rate recovery for the estimated capital costs of the plant (which the Commission
7 essentially granted subject to a price cap in IPC-E-09-03), a Langley Gulch QF would have to
8 agree to an on line date no later than September 2011. Mr. Kalich would require a QF to post
9 $45 per kilowatt. For the 330 MW Langley Gulch plant approved in Order No. 30892, Idaho
10 Power would have had to post $14.8 million in September 2009 as a guarantee it would be on
11 line by September 2011. Mr. Kalich's delay default proposal would allow termination of the QF
12 if it were not on line within 180 days of the proposed on line date. A "Langley Gulch QF"
13 would forfeit its $14.8 million security if not on line by March 2012. Langley Gulch is still not
14 on line today in May 2012, and is not even scheduled to be on line until at least June 2012. Its
15 approval could therefore be terminated.
16 If the Commission were to apply Mr. Kalich's proposal for QFs to the Langley Gulch
17 project, ratepayers could terminate the approval of the plant today and walk away from the
18 project altogether for any reason. If Langley Gulch were no longer needed because loads had not
19 materialized as predicted by Idaho Power, or if a less expensive offer materialized in the interim,
20 the Commission and the ratepayers could walk away from project, and Idaho Power's
Reading DI

1 shareholders would be responsible for any sunk costs. The prudence of Idaho Power's decision
2 in 2009 would be completely irrelevant once it went beyond the 2-year and 180 day period to
3 achieve on line status. This is not such a hypothetical situation because Idaho Power's load
4 needs are currently less than it projected when it sought approval of Langley Gulch in 2009.
5 Q. ARE THERE ANY OTHER RECENT EXAMPLES OF UTILITY PLANTS
6 TAKING LONGER THAN TWO YEARS TO ACHIEVE ON LINE STATUS?
7 A. Yes. In the case of Avista's proposed Reardan wind project, the Commission allowed
8 Construction Work in Progress (CWIP) and Accounting for Funds Used During Construction
9 (AFUDC) for the facility when the land was purchased in 2008. This treatment covered the
10 costs associated with the wind generation site land, land rights, reservation costs, and other
11 incremental costs associated with site evaluation, selection and acquisition to be accounted for as
12 construction work in progress. In its application requesting this preferential ratemaking
13 treatment, Avista represented that it intended for the project to be on line in 2011. To date,
14 Reardan is not on line. As pointed out above should the Reardan project ever be build, the utility
15 would request rate recovery for these costs that are on the Company's books and accruing
16 interest. The utility was able to obtain preferential accounting treatment that a QF would never
17 get, and provided no meaningful guarantees to ratepayers in exchange.
18 These two examples demonstrate that it is not at all out of the ordinary for it to take more
19 than two years from Commission-approval to bring a utility-owned generation project on line. I

1 recommend that the Commission reject this unfair 2-year requirement. If the Commission finds
2 that a 2-year requirement is needed for QF projects to protect ratepayers, the same requirement
3 must also be imposed and enforced for utility-built projects.
4 III. IDAHO POWER'S PROPOSAL FOR 5 YEAR CONTRACT TERMS
5 Q. DO YOU HAVE ANY COMMENTS ON IDAHO POWER'S
6 RECOMMENDATION THAT THE STANDARD TERM OF A QF CONTRACT BE
7 REDUCED FROM THE CURRENT TWENTY YEARS TO FIVE YEARS?
8 A. Limiting PURPA contract terms to five years would preclude the vast majority of QF
9 developers from being able to secure financing for their projects. FERC rules, in 18 C.F.R. §
10 292.304(b)(5), (d)(2)(ii), allow a QF to lock in long term rates for the term of a contract or
11 legally enforceable obligation with estimated avoided costs calculated at the time the obligation
12 is incurred. In establishing this option, FERC stated:
13 Paragraphs (b)(5) and (d) are intended to reconcile the requirement that the rates for
14 purchases equal the utilities' avoided cost with the need for qualifying facilities to be able
15 to enter into contractual commitments based, by necessity, on estimates of future avoided
16 costs. Some of the comments received regarding this section stated that, if the avoided
17 cost of energy at the time it is supplied is less than the price provided in the contract or
18 obligation, the purchasing utility would be required to pay a rate for purchases that would
19 subsidize the qualifying facility at the expense of the utility's other ratepayers.
20
21
22 Many commenters have stressed the need for certainty with regard to return on
23 investment in new technologies. The Commission agrees with these latter arguments, and
24 believes that, in the long run, "overestimations" and "underestimations" of avoided costs
25 will balance out.
26
27
28
Reading DI
Clearwater, Simplot, Exergy
-46
I Paragraph (b)(5) addresses the situation in which a qualifying facility has entered into a
2 contract with an electric utility, or where the qualifying facility has agreed to obligate
3 itself to deliver at a future date energy and capacity to the electric utility. The import of
4 this section is to ensure that a qualifying facility which has obtained the certainty of an
5 arrangement is not deprived of the benefits of its commitment as a result of changed
6 circumstances.40
7
8 FERC intended to provide a framework within which QFs would be able to obtain financing.
9 FERC provided for rates "to deliver at a future date," and agreed with commenters who
10 suggested there was a "need for certainty with regard to return on investment in new
11 technologies." No utility-owned generation resource will be paid off within five years, and a
12 five-year term cannot provide certainty on the return on investment.
13 Q. DID IDAHO POWER PROVIDE ANY BASIS FOR ITS PROPOSED 5-YEAR
14 CONTRACT TERM LIMIT?
15 A. Company witness Mark Stokes rationalizes this proposed reduction in term as a measure
16 to protect customers. Mr. Stokes testified:
17 Finally, in order to limit the risk customers are exposed to through longer-term contracts,
18 Idaho Power urges the Commission to reduce the standard contract term from 20 years to
19 five years. Idaho Power believes all of these proposed changes will resolve several
20 problems that exist with the current implementation of PURPA in the state of Idaho, and
21 protect utility customers from further harm. 41
22
23 Mr. Stokes's reasoning sounds much like that of the rejected comments in the FERC rulemaking
24 cited above. The Company's proposal is at odds with the intent of FERC, and would discourage
25 QF development.

-47
1 Q. DO YOU HAVE ANY OTHER COMMENTS ON THE PROPOSED 5-YEAR
2 CONTRACT TERM?
3 A. Yes. As discussed above in the Section dealing with the IRP methodology, when the
4 utility receives rate base treatment for one of its own generation facilities, the utility commits its
5 ratepayers to reimbursing the utility for its costs for the depreciated life of the project. The
6 capital cost recovery is guaranteed through rate base treatment and the majority of energy costs
7 are recovered annually through an annual power cost adjustment mechanism. Unlike a QF
8 project, those energy costs are not fixed and can go up dramatically from year to year. For
9 example, the price to supply Idaho Power's and PacifiCorp's jointly owned Bridger Coal Plant
10 increased significantly in 2010, and that cost increase was passed on directly to ratepayers.42
11 Utility customers are subject to fuel cost risks for utility-owned resources, but are protected from
12 the volatility of natural gas and coal prices when a fixed term QF contract is signed. I am certain
13 Idaho Power would not have been willing to build Langley Gulch if was assured of rate recovery
14 at a set rate for only a five year term rather than for the life of the project. This is yet another
15 example where the utilities propose that the Commission deprive QFs of similar treatment to the
16 utility's own generation resources.

1 IMPLEMENT AN ECONOMIC CURTAILMENT TARIFF APPLICABLE TO
2 EXISTING AND NEW QFS, WHICH IS ITS PROPOSED SCHEDULE 74?
3 A. Yes. In addition to my testimony below, I have attached as Exhibit 504 to my testimony
4 several discovery responses produced to date by the Company on the topic, and Exhibit 505,
5 which is a recent decision by the Montana Public Service Commission rejecting an economic
6 curtailment proposal by NorthWestern Energy for new QF contracts.
7 Idaho Power already possesses the right through its existing Schedule 72 to curtail QFs
8 for operational concerns to protect system reliability. In this case, the Company proposes to
9 implement economic curtailment of QFs under a proposed Schedule 74. Company witness
10 Tessia Park explains why she believes a FERC rule, 18 C.F.R. § 292.304(f), allows for the
11 Commission to approve the Company's proposal, even for existing QFs with long-term contracts
12 with fixed avoided cost rates and existing curtailment provisions. Ms. Park explains that she
13 believes the federal regulation and associated orders allow that "utilities may curtail higher cost
14 QF energy if the utility would have to dispatch less efficient, higher cost units (other than base
15 load units) to meet system load."43
16 In general, Ms. Park advocates for the right to curtail QFs during certain light loading
17 periods so as to avoid uneconomic operation at several Company-owned facilities that the
18 Company characterizes as "base load." The proposed Schedule 74 tariff attached to Ms. Park's
19 testimony includes the following as "base load" resources: Company-owned hydroelectric

1 resources, including all run-of-river generators and the Hells Canyon Complex, coal-fired
2 generating resources (Jim Bridger generating plant, Valmy generating plant, and the Boardman
3 generating plant), and the Langley Gulch power plant .44
4 Q. DO YOU HAVE ANY COMMENTS ON THE COMPANY'S PROPOSAL?
5 A. Yes. First, I am not an attorney, so I will not provide a legal opinion. However, it strikes
6 me as out of the ordinary to reach back in time to revise existing contracts. QFs have built and
7 secured financing of their projects based on assurance that the contractual provisions would be
8 honored by Idaho Power.
9 Also, Idaho Power appears to take issue primarily with intermittent QFs in its testimony.
10 But the issue identified by Idaho Power is already addressed in the existing contracts through a
11 wind integration charge. The Commission approved a wind integration charge for Idaho Power,
12 which reduces the otherwise available avoided cost rates for wind QFs and was developed
13 through a lengthy process, and ultimately a settlement of a contested case, to compensate the
14 Company and its customers for the estimated costs of wind integration. The wind integration
15 charge was a component of the estimate of future avoided costs at the time of contracting.
16 Ms. Park's attempts to explain why the Company's proposed curtailment provision
17 addresses different circumstances from the wind integration charge is not very convincing. In
18 response to the question of whether the $6.50 per MWh wind integration charge covers the cost
19 of balancing services, she testifies: "Partially. As an initial matter, it is important to point out
Id., Exhibit No. 5, p.1.
Reading DI
Clearwater, Simplot, Exergy
-50
I that the $6.50 wind integration charge was the result of a negotiated settlement and is not
2 reflective of the Company's actual integration costs."45 Idaho Power appears to take the position
3 that it can change the terms of its prior settlement agreement which has now been incorporated
4 into the avoided cost rates in many QF contracts. Idaho Power appears to believe that the
5 "actual" wind integration charges are different from those set forth in the existing PPAs, and
6 therefore an additional economic curtailment provision is necessary to make up the difference.
7 If the wind integration charge of $6.50 per MWh in existing contracts were found by the
8 Commission to be in excess of Idaho Power's actual wind integration costs, I doubt that Idaho
9 Power would agree (or the Commission would require it) to adjust the avoided cost rates in those
10 contracts upwards. The same is true of any other component of the avoided cost rates. The
11 avoided costs and all components thereto are estimates of actual avoided costs, which could be
12 higher or lower than actual projected costs. It does not appear fair to me for Idaho Power to try
13 to essentially impose additional wind integration charges through an economic curtailment
14 provision, any more than it would be fair for Idaho Power revise the avoided cost rates in any
15 other manner in any existing QF contract.
16 Q. DOES THE COMPANY'S PROPOSAL APPEAR TO DESCRIBE A SITUATION
17 SIMILAR TO THAT DESCRIBED IN THE FERC ORDERS THE COMPANY CITES?
18 A. I do not believe so. In developing 18 C.F.R. § 292.304(f), FERC stated:

1 This section was intended to deal with a certain condition which can occur during light
2 loading periods. If a utility operating only base load units during these periods were
3 forced to cut back output from the units in order to accommodate purchases from
4 qualifying facilities, these base load units might not be able to increase their output level
5 rapidly when the system demand later increased. As a result, the utility would be required
6 to utilize less efficient, higher cost units with faster start-up to meet the demand that
7 would have been supplied by the less expensive base load unit had it been permitted to
8 operate at a constant output.46
9
10 This language discusses a circumstance where a utility that operates only slow-ramping base
11 load facilities, such as a coal plants, would have to be back down those units during light loading
12 periods to accept QF output, but could not then start those units back up quickly enough to meet
13 the utility's next peak. The FERC regulation would apply if the utility had to instead meet the
14 next peak with a more expensive peaking resource, such as a less efficient gas peaking unit.
15 This does not appear to apply to Idaho Power for several reasons.
16 Idaho Power does not meet its load solely with slow-ramping base load coal plants. It
17 also meets its load with its hydroelectric plants and will soon meet load with its Langley Gulch
18 Plant, which it specifically described at the time of its request for its CPCN as being useful for
19 wind integration.
20 Q. HAS IDAHO POWER ADEQUATELY DEMONSTRATED THAT ITS SYSTEM
21 CONFIGURATION IS SIMILAR TO THE SCENARIO CONTEMPLATED BY THE
22 FERC RULE?

I A. No. The Company's discovery responses have not demonstrated that the circumstance
2 described by FERC would ever exist for Idaho Power. The Company's whole proposal hinges
3 on Idaho Power's position that it has a certain level of "must-run" generation, which cannot be
4 scaled back to accept the QF output it is contractually obligated to accept and buy when it is
5 provided. According to the Company, it must therefore curtail QFs.
6 Specifically, the Company lists the following resources as having the following "must-
7 run" output during typical low loading times of the year: Hells Canyon Complex (no less than
8 350 MW), Mid-Snake "run-of-river" hydroelectric projects (450 MW), the Bridger and
9 Boardman thermal units "that are 'in the money" (300 MW), and non-intermittent PURPA
10 generation (50 MW).47 That totals 1150 MW. Ms. Park testifies: "If Idaho Power were to cycle
11 off its thermal units in the middle of the night to accommodate PURPA generation, the Company
12 would need to start up its higher cost, less efficient natural gas peaking units or make more
13 expensive market purchases (assuming transmission would be available) to meet system load
14 during heavy load hours during the next day. ,48 There are several gaps in Idaho Power's logic.
15 Q. WHAT ARE THE GAPS IN IDAHO POWER'S LOGIC?
16 A. First of all, FERC 's description does not state that curtailments would occur when the QF
17 purchases may cause the utility to enter into more expensive market purchases; it refers to
18 operational circumstances at specific utility plants.

I Second, Ms. Park appears to state that its coal plants can be taken off-line and brought
2 back on line provided that Idaho Power gives the plant's operating utility up to one week
3 notice .
49 Thus, if Idaho Power can go a week without needing its coal plants during these light
4 loading periods, it appears to have no need to have them on line to begin with for operational
5 purposes. Idaho Power seems to suggest that it typically has such large load swings day-to-day
6 during these light loading times of the year that it must keep its Bridger and Boardman coal
7 plants on line to meet its peak loads during these times of the year. The actual load swings
8 within the weeks following light loading events of less than 1100 MW in the years 2010 to 2011
9 are contained in Idaho Power's Response to Exergy Production Request No. 22, contained in my
10 Exhibit 504. Although I am not an operations expert, it does not appear to me that Idaho Power
11 has fully considered whether it would really need to run gas peakers if it were to take more units
12 at the coal plants off-line during weeks where it expected a light loading event. Without the full
13 300 MW of minimum generation coal on line, as Idaho Power assumes there must be, there is a
14 reduced need to curtail QFs during a minimum loading event.
15 Another problem with Idaho Power's analysis is that it assumes it must run and accept
16 output from its run-of-river hydroelectric projects, and must curtail existing QFs to do so during
17 light loading periods. Idaho Power takes the position that this 450 MW of generation cannot be
18 taken offline to accommodate QF deliveries. However, Idaho Power stated in discovery that it
19 has the operational capability to run water through those projects (or spill it) without generating

-54
I electricity. 50 Idaho Power has not asserted that the FERC licenses prohibit it from taking the
2 plants offline in order to accommodate system reliability concerns such as a light loading event
3 where it has excess generation. Nor has Idaho Power asserted that the plants cannot be brought
4 back on line quickly if QF generation were to drop off or loads were to pick up.
5 Q. ARE THERE ANY OTHER FLAWS IN THE LOGIC OF IDAHO POWER'S
6 PERCEIVED RIGHT TO ECONOMIC CURTAILMENT?
7 A. Yes. Idaho Power appears to assume that it must keep the Bridger and Boardman Coal
8 plants on line during these periods where it experiences light loading. Its statement that it cannot
9 take coal plants offline is inconsistent with its statement that it does in fact take Valmy offline
10 during these periods "because of its relatively high dispatch cost and because it is not needed to
11 serve load during these low load times of year."51 Idaho Power appears able to take its coal
12 plants offline when it chooses to do so for its own reasons. Idaho Power appears to be
13 predetermining that certain coal plants will be "in the money" and therefore are "must run"
14 during a light loading event, even if running the coal plants to facilitate off-system sales means
15 Idaho Power must curtail QFs for general economic purposes. Idaho Power will soon have
16 Langley Gulch on line, and part of Idaho Power's justification to the Commission for that plant
17 was that it would be useful for integrating wind. It is not clear why Langley Gulch, the Hells
18 Canyon, and Mid-Snake hydroelectric projects, supplemented by occasional market purchases,
19 cannot be used to integrate wind during these light loading periods.

I Q. WOULD IDAHO POWER'S PROPOSAL APPLY TO ALL QFS?
2 A. No. Idaho Power has only requested that the proposal apply to any QFs over 10 MW
3 with a generator limiting device Idaho Power can use remotely (regardless of resource type).
4 Although Idaho Power designated the list of such QFs to be confidential, one can conclude from
5 the testimony that it would only affect more recently built QFs, for the time being. However, it
6 is also apparent that Idaho Power's economic curtailment provision would not apply to the four
7 QF projects owned by Idaho Power.
8 Q. DID YOU SAY IDAHO POWER OWNS QF PROJECTS THAT SELL TO
9 IDAHO POWER?
10 A. Yes. Idaho Power is a 50% owner, through a subsidiary named Ida-West Energy, of
11 four hydroelectric projects that sell QF output to Idaho Power. Those projects are South Forks
12 (8.2 MW), Hazelton B (7.7 MW), Wilson Lake (8.4 MW), and Falls River (9.1 MW). Idaho
13 Power's QFs are all under 10 MW, and therefore Idaho Power's QF projects would not be
14 subject to Idaho Power's economic curtailment tariff that applies to other QFs.
15 Q. DO YOU HAVE ANY OTHER COMMENTS ON THE CURTAILMENT
16 PROPOSAL?
17 A. Yes. Idaho Power provided the Commission with state utility commission orders from
18 Nevada and Florida implementing FERC 's curtailment rule. I am aware of a more recent state
19 commission order addressing this curtailment issue. Just last year, the Montana Public Service
20 Commission rejected a request by North Western Energy to prospectively include an economic
Reading DI
Clearwater, Simplot, Exergy
-56
I curtailment provision in future QF contracts. That decision is attached as Exhibit 505. The
2 Montana Commission found that the FERC regulation allowed for curtailment only in very
3 limited circumstances. The Montana Commission stated: "If market conditions occasionally
4 result in prices less than NWE's tariffed avoided costs, that is not in itself a sign that the
5 principle of consumer indifference is unlawfully being violated—no more than if a long-term
6 acquisition of NWE's own were to result in a fixed-and-variable cost-per-unit which were higher
7 than prices available on the spot market."52
8 That order also cited to the Montana regulation on the subject, which states: "Failure to
9 properly notify the qualifying facilities and the commission or incorrect identification of such a
10 period will result in reimbursement to the qualifying facility by the utility in an amount equal to
11 that amount due had the qualifying facility's production been purchased. ,53 This is consistent
12 with FERC 's description of its own provision, which stated: "any electric utility which fails
13 to provide adequate notice or which incorrectly identifies such a period will be required to
14 reimburse the qualifying facility, for energy or capacity supplied as if such a light loading period
15 had not occurred. ,54 In contrast, Idaho Power does not propose any provision whereby it would
16 be required to compensate QFs for inadequate notice, or for an improperly implemented
17 curtailment.

I The Commission may find this more-recent Montana order addressing a proposal for new
2 QF contracts useful in evaluating Idaho Power's proposal for existing QF contracts.
3 Q. DO YOU HAVE ANY CONCLUDING REMARKS ON THE CURTAILMENT
4 ISSUES?
5 A. Idaho Power acknowledges that it already possesses a tariff that allows for curtailment
6 for system integrity purposes, Schedule 72. Existing QFs agreed to circumstances under which
7 Idaho Power could curtail them for operational purposes when they decided to proceed with
8 building and operating their QF projects. I will let the lawyers debate the legality of unilaterally
9 amending contracts. However, I believe Idaho Power's proposal to alter the settled relationships
10 in PPAs would not be a policy that would encourage QF development. I am not convinced Idaho
11 Power meets FERC 's criteria for limited operational curtailment, even for new QF projects. I
12 recommend that the Commission not approve Idaho Power's proposed economic curtailment for
13 any QFs.
14 V. OWNERSHIP OF ENVIRONMENTAL ATTRIBUTES
15 Q. DO YOU HAVE ANY COMMENTS ON OWNERSHIP OF ENVIRONMENTAL
16 ATTRIBUTES?
17 A. I have very limited comments on ownership of environmental attributes, and have
18 included Exhibit 506 which contains a discovery response on the topic. Idaho utilities have
19 attempted at least twice to obtain a Commission order declaring the utility the owner of
Reading DI
Clearwater, Simplot, Exergy
-58
1 environmental attributes in Idaho QF contracts. 55 The Commission has never allowed the
2 utilities to insist on such a provision, and Idaho Power affirmatively disclaimed ownership in its
3 QF PPAs until recently. Some Idaho utilities have recently begun insisting on a contract
4 provision that clouds a QF's title to the environmental attributes by declaring ownership to be
5 governed by controlling law as it may exist at some future time during the term of the agreement.
6 This unilateral insistence on a term that QFs disagree with is a good example, like the delay
7 security issue addressed above, of an issue the Commission should resolve to provide
8 predictability in the QF market place. Idaho Power has described in a discovery response in this
9 case how it has been able to obtain certain QFs' agreement in last year to give Idaho Power some
10 of the QFs environmental attributes for no additional compensation, after Idaho Power first
11 insisted on a contract clause that clouded the QF's title to the environmental attributes. 56
12 Only Rocky Mountain Power witness Paul Clements has proposed to address ownership
13 of environmental attributes in this case. 57 He believes that the utilities should own the
14 environmental attributes without providing any additional compensation to the QF over and
15 above the avoided costs of energy and capacity. Neither Idaho Power nor Avista requested any
16 specific order on the issue in this docket.
17 Q. WHAT IS YOUR OPINION DR. READING?
18 A. In my opinion, insisting on utility ownership of RECs or insisting on a PPA clause

I clouding a QF's title and is not fair. The avoided costs in Idaho compensate QFs only for the
2 energy and the capacity provided. It appears the utilities' are making every effort in this case to
3 keep the compensation to QFs as low as possible. To also assert that the utility owns the non-
4 energy attributes of QF generation without any additional compensation is unreasonable. The
5 legal issues regarding ownership of environmental attributes are currently being litigated in
6 another docket, and I understand that it has been fully submitted with legal briefing for a few
7 months now.58 I recommend that the Commission resolve this dispute as soon as possible by
8 requiring the utilities to disclaim ownership of the environmental attributes for which they refuse
9 to compensate QFs.
10 VI. QF CONTRACTING PROCESS TARIFF
11 Q. DO YOU HAVE ANY COMMENTS ON ROCKY MOUNTAIN POWER'S AND
12 IDAHO POWER'S PROPOSALS THAT THE COMMISSION ADOPT A TARIFF THAT
13 WOULD ESTABLISH A CONTRACTING PROCESS?
14 A. Yes. Both utilities have expressed support for a contracting tariff so far in this case, but
15 only Rocky Mountain Power has actually proposed a specific tariff. Rocky Mountain Power
16 witness Paul Clements provided a proposed Schedule 38 for non-standard QF contracts, which
17 he states is based on tariffs used in Wyoming and Utah.59 Idaho Power witness Mark Stokes
18 expressed the Company's support for a contracting tariff, but he provided no specific tariff upon

I which any party can comment. The Company stated in discovery that it thought providing a
2 tariff with its initial filing would be premature. That is of course entirely inconsistent with its
3 submittal of a curtailment tariff proposed as its Schedule 74.
4 Q. DO YOU BELIEVE THAT A QF CONTRACTING TARIFF WOULD BE
5 USEFUL?
6 A. Yes, but only if the process is designed to prevent a utility from imposing unnecessary
7 delays in negotiations and only if the tariff requires meaningful deadlines with which the utility
8 must comply. Rocky Mountain Power's tariff fails on both of these requirements.
9 Q. WHAT ARE THE PROBLEMS WITH ROCKY MOUNTAIN POWER'S
10 PROPOSED TARIFF?
11 A. First of all, it only addresses a contracting process for non-standard QFs seeking
12 individually calculated avoided cost rates, and therefore provides no assurance that any particular
13 process will be followed for small QFs seeking published rates and standard contract terms.
14 Second, as Mr. Clements acknowledges, the deadlines for the utility to respond to QF
15 requests are far longer than deadlines authorized by the other states' tariff from which Mr.
16 Clements supposedly developed the proposed Idaho tariff. Specifically, Mr. Clements proposes
17 a 45-day response period for the utility to provide a draft contract after indicative pricing is
18 provided and all required information is submitted by the QF. This is an unnecessary and
19 excessive delay in the negotiating process. It is very difficult to believe that a sophisticated
20 utility like PacifiCorp cannot easily complete what should be a standard draft contract within a
Reading DI
Clearwater, Simplot, Exergy
-61
I shorter timeframe than 45 days.
2 Q. DO YOU HAVE AN ALTERNATIVE PROPOSAL?
3 A. I orouose using the standard contracting tariffs arrnroved by the Public Utility
4 Commission of Oregon. These tariffs were developed in a fully litigated proceeding (Oregon
5 Commission Docket No. UM 1129), not by a utility's own efforts to improve the tariffs of
6 another commission. Both Rocky Mountain Power (operating as PaciflCorp doing business as
7 Pacific Power and Light in Oregon) and Idaho Power already have experience using these
8 standard contracting procedures. PacifiCorp's Oregon Schedule 37 for standard QF contracts
9 and Schedule 38 for large QF contracts are both available on line. 60 Idaho Power's Oregon
10 Schedule 85, which addresses both standard and non-standard contracting practices, is also
11 available on line. 61
12 The Oregon tariffs for small QFs include a reasonable list of required information the QF
13 must provide to obtain a draft PPA, and require the utility to respond to QF inquiries within 15
14 business days. For large QFs, the utility must respond to inquiries within 30 days, and must
15 provide a final contract within 15 business days of agreement to all terms. This is a more
16 reasonable turn-around time than the 45 days proposed by Rocky Mountain Power. Each tariff
17 also includes a standard tariff contract for small QFs to limit the need to engage in protracted
18 negotiations for small QFs. The Oregon standard contracts in the Oregon tariffs may contain
19 some terms inconsistent with existing Idaho Commission precedent on certain terms, such as the
60 httlx//www.Dacificorp.cornles/cg/egfp.htrnl.
61
Reading DI
Clearwater, Simplot, Exergy
-62
1 90/110 band. Thus, I believe a standard Idaho contract should be developed and made publicly
2 available based upon existing Idaho orders, which already address many of the material terms of
3 aQFPPA.
4 I recommend the Commission adopt these standard tariff requirements based on the
5 Oregon tariffs, or some form of reasonable substitute with similar requirements.
6 Q. DO YOU HAVE ANY SUGGESTED IMPROVEMENTS IN THE EVENT THAT
7 THE COMMISSION DOES NOT UNDERTAKE TO MAKE AVAILABLE A
8 STANDARD CONTRACT DELINEATING ALL TERMS AND CONDITIONS?
9 A. Yes, even without a publicly available standard contract setting forth all terms, many
10 terms in QF PPAs have been set by the Commission through its history of implementing
11 PURPA. In the past, when the utilities have sought to implement a new condition in QF
12 contracts, the utilities have filed an application seeking Commission approval prior to
13 implementing such new conditions. For example, Case No. IPC-E-04-2, where Idaho Power
14 sought, but did not receive, approval to start including a term in QF contracts that declared Idaho
15 Power would have a right of first refusal to purchase any renewable energy credits generated by
16 a QF selling at avoided cost rates. Also, in Case No. IPC-E-03- 16, Idaho Power filed an
17 application to modify insurance and lien rights authorized as satisfactory risk mitigation
18 measures in levelized QF contracts. In Case No. IPC-E-07-04, Idaho Power applied for
19 Commission approval of its proposal to implement daily load shape pricing in QF contracts. In
20 each of these cases, interested parties had the opportunity to comment on the utility's proposal,
Reading DI
Clearwater, Simplot, Exergy
-63
I and the Commission approved a term that was less onerous on QFs than that initially sought by
2 the utility.
3 More recently, the utilities have simply begun inserting major new terms into QF
4 contracts when QFs have requested PPAs, without first obtaining Commission approval in
5 proceeding where all parties can comment. Recent contract terms implemented in this manner
6 include the delay security liquidated damages provisions and the terms clouding the QF's title to
7 environmental attributes, discussed above. The utilities then rely upon the Commission orders
8 approving contracts that contain such clauses as though the clauses were fully vetted with
9 comments by all interested parties in an open process. Vetting new contract terms in an
10 individual contract approval case is inappropriate because few QFs are likely to comment in
11 opposition to approval of the contract, knowing that the developer at issue must be anxious to
12 secure Commission approval. I recommend that the Commission admonish this new utility
13 practice of unilaterally inserting clauses into QF contracts without first seeking Commission
14 approval that the term is fair.
15 Q. DO YOU HAVE ANY OTHER SUGGESTIONS FOR QF TARIFFS?
16 A. Yes. FERC's regulations allow QF to choose to sell to a utility on an "as available" or
17 nonfirm basis, rather than pursuant to a legally enforceable obligation over a specified term. 62
18 The rates are calculated at the time of delivery, rather than at the time that the QF obligates itself
19 to a legally enforceable obligation. In today's market, the "as available" rates will be lower than
62 18 C.F.R. § 292.304(d)(1).
Reading DI
Clearwater, Simplot, Exergy
-64
I those in a contract over a specified term because market prices are lower than the cost to procure
2 a new resource. However, an "as available" contract option is useful to many QFs, and would
3 provide the utility with low-cost power in certain circumstances.
4 For example, if a QF is unable to resolve a dispute with a utility prior to its project
5 coming on line, an "as available" contract can provide the QF with the opportunity to complete
6 construction and achieve commercial operation prior to resolving the dispute. This may also be a
7 useful option for QFs who would prefer to use their generation to serve their own load during
8 most of the time, but sell to the utility "as available" when the output is not needed or desired to
9 meet the QF's host load.
10 Q. WHAT IS YOUR RECOMMENDATION?
11 A. Idaho Power has a tariff contract for nonfirm or "as available" deliveries in its Schedule
12 86, but neither Avista nor Rocky Mountain Power have such a tariff standard contract for
13 nonfirm deliveries. A tariff contract is important for QFs seeking to exercise this element of
14 FERC's regulations because a QF may want to exercise this option to make nonfirm deliveries
15 on short notice, such as in my example where the QF is unable to reach agreement with the
16 utility on the terms of a long term contract. I recommend that Avista and Rocky Mountain
17 Power also file a nonfirm standard contract similar to Idaho Power's Schedule 86. QFs should
18 have the opportunity to comment on the proposed standard contracts prior to Commission
19 approval.
20 VII. TRANSMISSION AND INTERCONNECTION ISSUES
Reading DI
Clearwater, Simplot, Exergy
-65
I Q. DO YOU HAVE ANY RECOMMENDATIONS WITH REGARD TO QF
2 TRANSMISSION AND INTERCONNECTION ISSUES?
3 A. I believe this is another issue where QFs are providing benefits to ratepayers in excess of
4 what a utility's own resources will provide. Under the existing Idaho precedents, PURPA QF
5 projects are solely responsible for the interconnection costs required to interconnect their
6 proposed projects to the utilities' systems, and are almost always responsible for the network
7 transmission upgrades required to deliver their energy from the point of interconnection with
8 utility's system to load. In some cases, Idaho Power and the ratepayers have shared in the cost of
9 network upgrades.63 Essentially, under those few authorized sharing arrangements, the QF pays
10 25% of the total cost regardless of its performance, and it obtains a refund of an additional 50%
11 paid up front only if it performs.
12 In contrast, all prudently incurred interconnection and transmission costs associated with
13 a utility-owned project will be included in customer rates Similarly, when federal jurisdiction
14 applies to an interconnection, developers receive a refund for the entire cost of network
15 transmission upgrades required for their projects under FERC interconnection rules.64
16 The Commission could improve its existing precedent on this issue in two ways. First,
17 the existing cost sharing arrangement is non-binding based upon the Commission orders
18 implementing it. The Commission should provide QFs with the assurance of an established
63 IPUC Order No. 32136, Case No. IPC-E-09-25 (2010).

-66
I policy. Second, the policy should treat QFs the same as the alternative to QFs. QFs should be
2 treated the same as the utilities and other developers. When the Montana Public Service
3 Commission recently examined this issue it stated NorthWestern Energy "improperly sought to
4 assign all network upgrade costs to the QF instead of the amount of those costs that exceeded
5 what [NorthWestern Energy] otherwise would incur to connect its avoidable resource."65 This is
6 a fair approach, and I recommend that the Idaho Commission establish the same policy for equal
7 treatment by entitling the QF to 100 percent refund of network transmission upgrades on similar
8 terms to those provided for FERC jurisdictional interconnections.

10 CONCLUSION
11 Q. DR. READING, DO YOU HAVE AN CONCLUDING COMMENTS REGARDING
12 THIS DOCKET AND YOUR RECOMMENDATIONS?
13 A. Yes, I do. I am fully cognizant of the situation Idaho Power is in with respect to the
14 magnitude of wind generation it is being required to integrate into its system. I believe, based on
15 my many years of involvement in utility regulation in Idaho, that this was part of the genesis of
16 this docket. I also believe Idaho Power, along with the other two investor-owned utilities, is
17 using that fact to dismantle PURPA in Idaho without regard for the ratepayer or this
18 Commission's obligations under PURPA. The SAR methodology has been resilient in the past

I in responding to changed circumstances, and it continues to stand out as the single best
2 methodology for this Commission to use in fulfilling its obligations under PURPA.
3 I do not accept Idaho Power's "the sky is falling" basis for making wholesale destructive
4 changes to the PURPA implementation that has taken this Commission years to develop and fine
5 tune. The Commission currently has the tools at hand to respond to changing economic
6 conditions while at the same time properly implementing PURPA.

10 INDUSTRIAL CUSTOMERS OF IDAHO POWER. CAN YOU ADDRESS THAT
11 PERCEIVED CONFLICT?
12 A. I would be happy to do so. To find evidence that the ratepayers and the PURPA
13 industry's interests are aligned, one need look no farther than the first page of my testimony. I
14 am testifying today on behalf of Avista' s largest retail customer who also is Avista's largest
15 PURPA vendor. I am also testifying on behalf of one of Idaho Power's largest customers who is
16 also one of Idaho Power's largest PURPA vendors. Finally, I am testifying on behalf of Idaho's
17 largest and most successful PURPA wind developers. The fact that these three entities have
18 common ground in promoting a reasonable and fair implementation of PURPA in opposition to
19 the three investor-owned utilities is significant because all three live in the real world.

1 A. First, none of my clients operate in a state sanctioned monopoly environment and none
2 are virtually assured a return on investment. All are rational actors in highly competitive
3 industries. The fact that all three see a need to have a robust independent power market and at
4 the same time have fair retail rates is not an oxymoron - it is in the best interests of both the
5 PURPA developers and the ratepayer. The single fact that sophisticated self-interested
6 ratepayers have joined forces with a sophisticated self-interested PURPA developer to advocate
7 against the PURPA-killing proposals made by the utilities is compelling -- and should be very
8 instructive to the Commission as it deliberates on the many complex and difficult issues
9 presented in this docket.
10 Q. DOES THAT CONCLUDE YOUR TESTIMONY ON MAY 4,2012?

REQUEST FOR PRODUCTION NO. 261s1cl: Reference the Direct Testimony of
Mark Stokes, p. 18, describing the differential between what Idaho Power will pay for
PURPA generation in 2012 and the amount it would pay to purchase the same amount
of generation as a "firm" product in the Mid-C market.
(a)Please provide a detailed definition and an example of a "firm" product,
including the maximum term (years and months) for which Idaho Power could secure a
firm market purchase in 2012. Does this cost include the cost of firm transmission from
Mid-C to Idaho Power's system?
(b)Please estimate the amount of firm transmission (MW) Idaho Power
possesses or could secure from Mid-C to Idaho Powers loads.
(b)[sic] Using the same figures for the cost of firm market product used in
the testimony, please provide the differential for the cost for Langley Gulch (including all
variable and fixed costs passed onto customers through rates) for each year from 2012
to 2021, in dollars and in $/MWh. Please prorate the costs of market purchases for
2012 to account for the date Idaho Power estimates Langley Gulch costs will be
incurred by customers in that year.
(c)Please provide a detailed explanation of the assumptions used in the
calculation in the testimony and in the calculations in response to this request.
RESPONSE TO REQUEST FOR PRODUCTION NO. 26Isicl:
(a) The following is taken from the Western Systems Power Pool ("WSPP")
website (www.wspp.org) which includes information regarding energy trading in the
western United States:
The Current WSPP Agreement effective October 21, 2011, is
the most commonly used standardized power sales contract

in the electric industry. It is approved by the FERC and used
by jurisdictional and non-jurisdictional entities. Once signed,
the Agreement allows instant access to power trading within
the membership.
The mission of the organization is to provide a catalyst for an
efficient and robust wholesale electric power market. WSPP
accomplishes this by constantly facilitating refinements to the
Agreement and promoting trading relationships.
Under the WSPP Agreement, a "firm" product is defined as a firm capacity and/or
energy transaction whereby the Seller has agreed to sell or exchange and the
Purchaser has agreed to buy or exchange for a specified period available capacity with
or without associated energy which may include a Physically-Settled Option and a
capacity transaction in accordance with the Agreement, including Service Schedule C,
and any applicable Confirmation. The current maximum term at Mid-C on the ICE is
through the 2015 calendar year. The cost does not include transmission from Mid-C to
Idaho Powers system.
(b)Each month, the Idaho Power Delivery business unit notifies Idaho
Power's Power Supply business unit of the transmission allocations set aside to serve
network load for the next 14 months. Monthly amounts vary, but July has historically
been the most constrained month. The most recent report from Delivery indicates a
total of 134 MW of firm transmission capacity between Mid-C and Idaho Power is set
aside to serve network load in July 2012.
(b)[sic] Idaho Power has not performed this analysis or compiled the data
that would be required.
(c)The comparisons between the cost of PURPA generation and firm
purchases from the Mid-C market are based on the fixed contract price of PURPA

REQUEST FOR PRODUCTION NO. 29(sicl: Reference the Direct Testimony of
Mark Stokes, p. 39, stating, "The estimated 20-year, levelized cost of Langley Gulch is
$68.55 per MWh using a 90 percent capacity factor assumption (to be consistent with
the SAR capacity factor assumption), and Idaho Power's current natural gas price
forecast."
(a)Please provide work papers and all cost assumptions for the $68.55 per
MWh figure for Langley Gulch, including interconnection and transmission costs, gas
price and transportation/storage costs, heat rate, assumed heat rate degradation,
equivalent availability factor, capital cost, variable O&M, fixed O&M, O&M escalation
rates, and inflation, as well as any other cost assumptions. Please provide the basis for
each assumption for each of the listed items.
(b)Please provide the levelized $/MWh cost of Langley Gulch for both energy
and capacity at the 84% capacity the Company expects the facility will have available
for planning purposes. Reference IPUC Order 30392, p. 17.
(c)Please provide the levelized $/MWh cost of Langley Gulch for both energy
and capacity at the 20 year average 49% capacity factor provided in Karl Bokenkamp's
Direct Testimony, p. 23.

REQUEST FOR PRODUCTION NO. 331s1c1: Reference the Direct Testimony of
Karl Bokenkamp, p. 25, describing Idaho Power's proposed assumption that each
thermal unit will assigned an incremental cost based on full load operation.
(a)is it true that when a thermal unit is operated at less than full load that the
incremental cost per MWh increases?
(b)For each of the Company's thermal units, please provide: (1) heat rate at
maximum output, (2) heat rate at minimum operating output, (3) incremental energy
cost at the heat rate in (1) and (2).
(c)For each of the Company's thermal units, please provide the number of
hours per year in the years 2008 through 2011 that the unit operated at full load
operation.
RESPONSE TO REQUEST FOR PRODUCTION NO. 331s1c1:
(a)It is true that when a thermal unit is operated at substantially less than full
load, the incremental cost per MWh does increase. This is because the efficiency of a
generating unit decreases when it is operated at substantially below its design loading.
However, depending on design of the individual unit, the highest operating efficiency
(the best or lowest heat rate) may occur at less than full load. This is similar to fuel
efficiency for your car - your car may be capable of running at 70 miles per hour, but
your best fuel efficiency may occur at 55 miles per hour.
(b)Please see the Excel file provided on the non-confidential CD.
(c)Please see the Excel file provided on the non-confidential CD. In addition
to providing the requested information, another analysis has been conducted to
determine the number of hours that each unit operated at or above 90 percent of full

4.Fuel costs are estimates and are based on values used in previous AURORA analyses. Fuel costs have a significant
impact on incremental cost.
5.Variable O&M costs are approximate and are based on values used in previous AURORA analyses
6.Output of combustion turbines varies with temperature (output decreases as temperatures increases). The above
estimates are based on an ambient temperature of 59 degrees F.
7.For Danskin Unit #1 and Bennett Mountain, minimum load is 60% of the full load output.
8.Because of their lower output and efficiency, Danskin Unit #2 and #3 are not currently operated at

REQUEST FOR PRODUCTION NO. 41: Reference the Direct Testimony of Karl
Bokenkamp, p. 29, lines 6-8. Please state whether Idaho Power intends for all "queued"
Us, as defined in the testimony, to be included in Idaho Power's IRP for all purposes,
including prudency of the decision to build a new utility-owned plant in a CPCN
proceeding for the DSM investments. Please explain how including all "queued" QFs in
the load and resource balance for all purposes will impact future utility plant CPCN
applications and DSM proposals, and other action items in the IRP.
RESPONSE TO REQUEST FOR PRODUCTION NO. 41: Historically, Idaho
Power has only included signed qualifying facility ("QF") contracts in the load and
resource balance used to prepare the Integrated Resource Plan ("IRP") because of the
uncertainty surrounding if and when additional projects may come on-line. Idaho
Power's need for new resources, both supply-side and demand-side, is driven by peak-
hour load growth. As long as the vast majority of new QF projects continue to be wind
resources, Idaho Power does not believe the "queued" QF projects would impact future
utility plant Certificate for Public Convenience and Necessity applications, demand-side
management proposals, or other IRP action items.
If Idaho Power had included a total of 700 megawatts ("MW") of QF wind in the
load and resource balance used in the preparation of the 2011 IRP, the resulting
preferred portfolio would likely be unchanged. Because wind resources can only be
counted on to provide 5 percent of nameplate capacity towards meeting peak-hour load,
700 MW of wind only displaces 35 MW of summertime capacity needs.
The queuing process as described in Mr. Bokenkamp's testimony would be used
to determine when the highest incremental cost displaceable resource has been fully

offset by the proposed OF projects. Once this level is reached, the model would be re-
run to include the cumulative OF project energy and determine the new highest
increment cost displaceable resource for each hour. The process of determining the
highest cost displaceable resource for each hour makes use of the most recent IRP
data, but does not change the IRP data or results. Therefore, for the IRP planning
process, Idaho Power would continue to use the forecast generation for all OF projects
with signed contracts.

Planning Manager, Idaho Power Company, in consultation with Donovan E. Walker,

REQUEST:
Please provide all studies, analysis, or documents used to develop this $45/kw amount.
RESPONSE:
The $45/kW delay security amount is intended to create a source of liquid funds which the utility
can draw upon in the event that damages are incurred if a new project does not meet its online date.
A PURPA contract for Clearwater Paper's facilities do not require delay liquidated damages, as its
facility already is operating and Avista does not presently require its PURPA contracts to contain
delivery term or operating security.
In 2009, Avista commissioned a survey of utilities and their required delay (also referred to
"development") security amounts for renewable projects. The results are as follows:

Further, both Idaho Power and Avista presently include delay liquidated damage security deposits
of $45/kW. Rocky Mountain Power requires a delay liquidated damage deposit equal to the
greater of $45/kW, or the full value of the first 3 months of expected electricity deliveries. Avista
understands that a similar delay liquidated damages provision is defined for PURPA projects
selling power into Oregon. Therefore it would appear that it is common practice to I) apply
liquidated damages to PURPA contracts and 2) a $45/kW level is reasonable, as is evidenced by
practice in Idaho and other jurisdictions.

REQUEST:
Reference IPUC Order No. 30611, at p. 2, approving CWIP and AFUDC for the Reardan wind
farm, which Avista intended to reach commercial online status by year end 2011, and stating
"Avista believe[d] it [wa]s cost effective and prudent to secure land rights and equipment now,
even though actual construction will not begin until 2011."
(a)Please explain the status of the Reardan wind farm, whether it came online as projected in
2011, its approximate online date, and the reason for any delays.
(b)Please identify and provide the costs spent by Avista on the Reardan project to date.
Please identify any costs included in Avista's retail rates implicitly or explicitly.
(c)Please explain how Avista was able to change its plans for Reardan's projected online
date without compromising Avista's need to acquire RPS compliant generation to meet
Washington RPS targets. Did Avista acquire another RPS compliant resource instead of
Reardan?
(d)What were Avista' s actual costs incurred in the delayed or permanently deferred online
date for Reardan? Please provide all supporting work papers and an explanation.
(e)Will Avista provide rate payers a $45/kw delay damages refund if Reardan is not online
within 180 days of year end 2011, as projected in the application in Case No. AVU-E-08-04?
Please explain why or why not.
RESPONSE:
(a)Avista has delayed plans for construction of the Reardan wind project. The recent
acquisition of the Palouse Wind Farm through a competitive RFP meets our needs through
at least 2019. The Company continues to maintain the permitted Reardan wind project as
an option for future development and continues to collect data at the site.
(b)Please seethe attached spreadsheet entitled "Reardan_Costslhii_Mar_2012.xlsx." No
costs are currently included in retail rates related to the Reardan Wind Farm.
(c)Avista was able to change plans through the acquisition of the Palouse Wind Project that
meets our immediate needs for RPS resources.
(d)Please see response (b).
(e)No. The alignment of customer interests is different as between a PURPA fixed-priced
contract as compared to a utility-owned generation resource. As PURPA resources are
provided to a utility at a fixed contract price, that contract price does not vary based on the
actual cost of the PURPA generation project. To help ensure that fixed price benefit is
delivered, it is in customers' interest to have PURPA contract terms structured such that
Exhibit 503
GNR-E-1 1-03
D. Reading: Simplot,
Exergy, Clearwater
Page 5
Page 2
developer interests are aligned with customer interests. A utility, such as Avista, does not
provide a price guarantee for its utility-owned generation assets, but instead provides
long-term generation ownership value to customers at cost. In other words, customers
benefit from paying only actual costs over the life of a very long-term resource. In
contrast, the guarantees embedded in PURPA contracts define costs utility customers will
pay over the term of the agreement. A delay damages provision is a means to ensure that
developer and customer interests are aligned, and that customers receive the benefits from
the PURPA contract, consistent with the pricing and other terms and conditions that have
been guaranteed to the developer under the PURPA contract.

REQUEST FOR PRODUCTION NO. 12: Reference the Direct Testimony of
Tessia Park, p 18, discussing the Company's proposed Tariff Schedule 74 (Exhibit No.
5).
(a)Please identify the provision of Idaho Power's proposed Tariff Schedule
74 that would compensate Us for curtailments occurring without providing the required
notice, or where the basis for the curtailment was not supported by the circumstances
described in 18 C.F.R. § 292.304(f). If no such provision is included, please explain
why.
(b)Please explain Idaho Power's basis for only proposing to provide Us
one-hour notice prior to such curtailments. Is Idaho Power aware of any FERC or state
commission order that has authorized advance notice of one hour or less to QFs in
implementing 18 C.F.R. § 292.304(f)?
(c)Does Idaho Power believe that it has the right to curtail Us to under 18
C.F.R. 292.304(f) even when the applicable QF contract provides for no such
curtailment? If so, please explain the basis for this position.
RESPONSE TO REQUEST FOR PRODUCTION NO. 12:
(a)Tariff Schedule 74 does not contemplate curtailing QFs without providing
the required notice. Since it is not Idaho Power's intent to curtail Us pursuant to
Schedule 74 without prior notice, no such provision was included.
(b)Because wind is intermittent and because QFs do not provide Idaho
Power with schedules for their generation, Idaho Power has no way of knowing how
much wind generation it is going to have on its system until usually the hour or even
minutes before a scheduled period. While Idaho Power is not aware of any Federal

Energy Regulatory Commission ("FERC) or state commission order that has authorized
advance notice of one hour or less to Us in implementing 18 C.F.R. § 292.304(f),
there is nothing in the FERC rules which prohibits providing only one-hour notice.
(c) Yes, Idaho Power believes it has the right to curtail Us under 18 C.F.R. §
292.304(f) even if the applicable QF contract provides for no such curtailment. It is
Idaho Powers position that all FERC rules related to PURPA, including 18 C.F.R. §

mentioned in the firm energy sales agreements Idaho Power has with PURPA
developers.

of Langley Gulch will be approximately $22."
(a)What is the current price of gas used to calculate the $22 Langley Gulch
dispatch cost?
(b)What is the price of gas Idaho Power expects to pay when Langley Gulch
comes on line the summer of 2012, and the expected dispatch cost at that gas price?
(c)What price of gas does Idaho Power expect to pay for Langley Gulch, and
what is the associated expected dispatch cost annually over the next 20 years?
(d)What is the fixed cost of Langley Gulch in $/MWh? What is the fixed cost
of a QF to the Company?
RESPONSE TO REQUEST FOR PRODUCTION NO. 13:
(a)A natural gas price of approximately $3/MMBtu results in an estimated
Langley Gulch dispatch cost of $22/megawatt-hour ("MWh").
(b)Current forward gas prices for July 2012 indicate a cost of $2.401MMBtu.
This would result in a Langley Gulch dispatch cost of $1 7.62/MWh.
(c)The 2011 IRP low-case, natural gas price forecast is currently viewed as
the best long-term forecast Idaho Power has available, although this forecast reflects
near-term gas prices that are higher than near-term forward market prices. This
forecast is relatively close to the most recent natural gas price forecast issued by the
Northwest Power and Conservation Council. The 2011 IRP low-case gas price forecast
and the resulting dispatch cost of Langley Gulch are provided through 2030, the end of

of a OF contract would be the fixed rate contained in the contract. As presented on
page 8 of Company witness Stokes's testimony, the remaining future fixed cost of the
119 signed and approved contracts will be $3.6 billion throughout the term of the
agreements. Based on estimated generation of 44,414 GWh from these projects
throughout the term of the agreements, the average rate paid for this energy would be
$81 .06/MWh.

(a)Relatively high customer demand is not defined by a specific numerical
value but rather when conditions exist such that load demands exceed the minimum
hydro and thermal generation on the system.
(b)Idaho Power is unable to forecast the level of demand at which time there
will be no limiting conditions for existing and contracted Us as the level of demand is

In addition, the non-confidential CD contains a copy of a Settlement Agreement
between Idaho Power and the U.S. Fish and Wildlife Service which contains certain
environmental provisions that place constraints around how the Company operates the
Mid-Snake hydro projects (e.g.), Shoshone Falls, Bliss, Upper Salmon, and Lower
Salmon).
At run-of-river projects, generation increases as flow increases and generation
decreases as flow decreases.
(d) Each licensed facility has the physical capability to spill water without
generating electricity. The proposed operations in the applications for FERC licenses
and state water quality certifications did not include spill except when flows exceeded
plant capacity or when generators tripped off-line in emergency situations. To the
contrary, operations may require an amendment to the FERG licenses and/or state
water quality certifications.

REQUEST FOR PRODUCTION NO. 21: Reference the Direct Testimony of
Tessia Park, p. 1, stating dispatch costs for the Company's coal units are approximately
$30/MWh and for Langley Gulch are $22/MWh.
(a)Please explain why the Company would not take its coal plants ofiline and
instead run Langley Gulch during times when it expects to have light loading periods.
(b)For Langley Gulch, the run-of-river hydro projects, and the Hells Canyon
Complex, please provide the minimum and maximum output for each that Idaho Power
could reasonably expect to obtain during periods of the year that Idaho Power expects
to experience light loading events. Please explain the basis for the estimates for each
category.
RESPONSE TO REQUEST FOR PRODUCTION NO. 21:
(a)Coal plants cannot be shutdown and restarted on a daily basis and,
consequently, they can only be turned down to minimum generating levels during light
load periods in order to have their capacity available for the next days' heavy load
period.
(b)When on-line, Langley Gulch will typically be operated during light loading
events between its minimum and maximum generating levels. It is expected that
Langley Gulch will be dispatched somewhere between its minimum and maximum
levels depending primarily on system load, actual wind generation, and plant
economics. The minimum and maximum levels vary seasonally, but are reasonably
expected to be about 160 MW and 300 MW, respectively.
The minimum and maximum output for the run-of-river hydro projects during light
loading events is dependent on water conditions in the Snake River Basin as no

significant reservoir storage is available at any of Idaho Power's projects. The water
conditions are very predictable with respect to short-term planning; however, a longer-
term basis review of Snake River Basin streamfiow records indicates pronounced
season-to-season and year-to-year variability. Therefore, expected minimum and
maximum output levels depend on the type of water year. For capacity planning
purposes, under median water, Idaho Power expects to get 285 MW from the run-of-
river plants (see 2011 IRP, page 117).
For light loading events occurring during the nearly eight month period from mid-
October through May, the minimum output for the Hells Canyon Complex is driven by
Idaho Power's efforts to maintain flow levels suitable for Snake River fall Chinook
salmon spawning, rearing, and emergence. Idaho Power manages its operations to
provide stable flows during the approximately two month spawning period (mid-October
to mid-December) and, after spawning, maintains the Hells Canyon Complex outflows
at or above the stable spawning flow level through rearing and emergence (mid-
December through May). The spawning flow level varies from year-to-year depending
on water supply in the Snake River Basin, but, in the past, has ranged from about 8,500
cfs to 14,000 cfs. While minimum output can vary from hour-to-hour depending on
water management for the three dam complex, it is reasonable to estimate minimum
output of about 300 MW during years when spawning flows of 8,500 cfs are provided,
and about 550 MW during years when spawning flows of 14,000 cfs are provided.
Outside of the mid-October through May period, Idaho Power maintains minimum
Hells Canyon Complex outflows in compliance with downstream navigation
requirements. These requirements depend on several factors, including inflow to

Brownlee Reservoir and Salmon River discharge, but generally Idaho Power maintains
Hells Canyon Complex outflows of 6,500 cfs or higher during this period (June to mid-
October). High Brownlee inflow conditions, particularly during the early summer, may
necessitate Hells Canyon Complex outflows substantially greater than 6,500 cfs.
Minimum output during these high flow periods is variable, and typically quite high.
During periods when Hells Canyon Complex outflows can be reduced to levels of
approximately 6,500 cis, it is reasonable to estimate minimum output levels of about
250 MW.
With respect to maximum output, Idaho Power manages the Hells Canyon
Complex such that maximum output during light loading periods is typically only
nominally higher than the minimum output obtained. Capacity during these periods is
not needed, and the flexible generators of the Hells Canyon Complex can vary their
output accordingly.

Planning Manager, Idaho Power Company, in consultation with Donovan E. Walker,

REQUEST FOR PRODUCTION NO. 22: Reference the Direct Testimony of
Tessia Park, P. 24, describing conditions where the Company has sufficient base load
generation to service 1,100 MW of load.
(a)For the years 2010 and 2011, please provide the hours and days of the
year that Idaho Power's load was at or below 1,100 MW.
(b)Please provide the number of hours, days, weeks, or months in advance
that Idaho Power can accurately predict that reaching loads this low will occur.
(c)For each such occurrence, please provide the maximum load within the 7
days following the light loading event.
RESPONSE TO REQUEST FOR PRODUCTION NO. 22:
(a)There were 89 hours in the years 2010 and 2011 where the Idaho Power
system load was 1100 MW or less (data from P1 Series AGC_TOTALL). Idaho Power
experienced load of 1100 MW or less in the months of April, May, June, October, and
November of 2010 and in the months of April, May, and October of 2011. Table 22.1
provided on the non-confidential CD lists the hours when the system load was 1100 MW
or less during the years 2010 and 2011.
(b)Because the term "accurately predict" is subject to a number of
interpretations and is not clearly defined in this Request, Idaho Power is unable to
provide the requested information.

REQUEST FOR PRODUCTION NO. 23: Reference the Direct Testimony of
Tessia Park, p. 24, describing the minimum base generation (300 MW thermal, 817 MW
hydro, and 50 MW non-intermittent PURPA) to be near 1,100 MW. Please explain why
Idaho Power could not plan for an expected light loading period coinciding with possible
excess OF generation by un-designating the network resource status of a specified
quantity of this base generation, and using its fast-ramping, remaining Hells Canyon
capacity to serve load in the event that intermittent OF generation did not occur as
predicted
RESPONSE TO REQUEST FOR PRODUCTION NO. 23: The particular network
resource that is undesignated must be used to supply energy for a sourced sale. If
Idaho Power undesignates and sells power from a baseload resource, that resource
must be able to supply the system sale. In order to sell firm resources into the market,
Idaho Power limits the amount of generation from the baseload resources to 50 percent
of that resource's available generation capacity to ensure sufficient generation exists
from that facility to supply the firm sale and to comply with Idaho Power's Open Access
Transmission Tariff ("OA1T). Additionally, Hells Canyon is limited in ramping ability
due to downstream river level changes of one foot per hour. This severely limits the
ability for Hells Canyon units to ramp to support large deviations in outflow. Idaho
Power sets aside capacity in the pre-schedule or day ahead to cover reserve
requirements and meet load demands. Idaho Power's procedures require the Company
to sell or buy energy to balance the system in pre-schedule based on generation and
load forecasts, this takes into account wind forecasts, as well as limitations on hydro

REQUEST FOR PRODUCTION NO. 42: Reference the Direct Testimony of
Tessia Park, page 11, containing the following dispatch costs: Langley Gulch
($22/MWh), coal generators (generally below $30/MWh). These values are different
from those provided for the hourly variable generation costs provided in the confidential
attachment to Staffs Request No. 2. Please explain the discrepancy and provide the
correct dispatch costs for each of the Company's gas and coal plants.
RESPONSE TO REQUEST FOR PRODUCTION NO. 42: In Tessia Park's
testimony, the data stated for the dispatch costs of the Langley Gulch power plant and
the coal generations were representative estimates. These dispatch costs were
representative of average dispatch costs, not specific dispatch costs by resource as
was the data provided in the Company's response to the Idaho Public Utilities
Commission Staffs Production Request No. 2.

REQUEST NO. 5: The direct testimony of Tessia Park discusses generally the
low loading conditions when the proposed Schedule 74 might require curtailment, and
describes a representative example on pages 23-24. Has Idaho Power conducted any
analysis or studies to attempt to estimate the frequency, duration, and magnitude of
curtailments that might be invoked in the future or that would have been invoked in the
past if its proposed Schedule 74 was in place? Please provide a copy of any analysis
or studies. If no analysis or studies have been done, please provide estimates if
possible.
RESPONSE TO REQUEST NO. 5: Idaho Power has not conducted an analysis
or study to estimate the frequency, duration, or magnitude of curtailments that might
have been invoked or would be invoked in the future under the proposed Schedule 74.
Idaho Power estimates that curtailments under Schedule 74 would occur during periods
of low load and be more likely during high water conditions, such as in the spring
months, and during periods of low market prices, which are indicative of there being no
market demand for Idaho Power's surplus energy.
As part of determining the hourly incremental cost in the alternate IRP
methodology proposed in Company witness Bokenkamp's testimony, there are a small
number of hours each year where the hourly incremental cost is zero. While these
zero-cost hours are used in the calculation of the monthly average heavy load and light
load price, they do not estimate the amount of curtailment expected under Schedule 74.
During the zero-cost hours, Idaho Power would still be accepting delivery of QF
generation, and paying the project the appropriate monthly average heavy or light load
price. Similar conditions tend to exist (low load and high water) at times when the

however, they are not synonymous.

Page 40
REQUEST NO. 6: If Idaho Power's proposed Schedule 74 were to be approved
by the Commission and QFs were curtailed during certain low load conditions, would
the avoided cost rates computed based on Aurora analysis be impacted? Has Idaho
Power conducted any Aurora analysis to compute avoided cost rates under an
assumption that QFs could be curtailed under certain low load conditions?
RESPONSE TO REQUEST NO. 6: Avoided cost rates computed by AURORA
are set for the duration of the contract based upon the QF's estimated hourly generation
profile for a period of one year, and this computation is not impacted by possible
curtailment. However, if Idaho Power must pay for curtailment, it must also be able to
recover such payments. If Idaho Power may curtail without payment, no adjustment to
avoided costs through the integration charge is necessary.
In its updated wind integration study, the Company has been careful to not
include any costs associated with curtailment in the wind integration cost analysis. The
AURORA model used by Idaho Power to determine the avoided cost of energy is not
capable of modeling wind curtailment and therefore curtailment is not valued in the
pricing proposed by Idaho Power. Because a certain amount of curtailment is
anticipated in the modeling performed as part of the wind integration study, Idaho Power
does not believe it would be appropriate to account for curtailment in the avoided cost
pricing model.

Planning Manager, Idaho Power Company, in consultation with Donovan E. Walker,

QFs, should have been allowed to comment in this proceeding on the significant impact of the
proposed curtailment language. NWE also argued that a host of generically-stated "problems"
with the QF regulatory regime are the responsibility of this Commission.'
5.NWE argues in its Petition (pp..1-2) that its obligation to purchase electricity from
QFs produces surplus power situations that harm the interests of NWE and its customers in
certain hours, and that this resulting surplus must be sold for less than the purchase price. To
address this situation, NWE proposes curtailment language for its new QF contracts that would
relieve it of its obligation to purchase QF output during "light load" hours. NWE's proposed
remedy for this situation is the following language:
No Obligation to Acceot Energy: Northwestern shall not be obligated to accept or pay
for Energy from Seller during any period in which, due to operational circumstances, the
acceptance of Energy from Seller and Similarly-Situated Suppliers of energy to NorthWestern is
expected to result in NorthWestern system costs greater than those which NorthWestern would
incur if it did not accept such deliveries, including periods in which NorthWestern generated an
equivalent amount of energy itself. For illustrative purposes only, and without limiting the
circumstances under which NorthWestern might be relieved of the obligation to accept or pay for
Energy from Seller under this section, an example of such a period is a period when
NorthWestern would be forced to shut down a base load or intermediate load plant in order to
accept deliveries of Energy from Seller and such base load or intermediate load plant could not
then be restarted and brought up to its rated output to meet the next period's peak load and
NorthWestern would consequently be required to utilize costly or less efficient generation with
faster start-up or purchase higher-priced energy to meet the demand that could have been met by
the base load or intermediate load plant but for such purchases from Seller. During periods in
which NorthWestern is purchasing energy both from Seller and from Similarly-Situated
Suppliers, the implementation of any curtailments of deliveries of energy is subject to the sole
discretion of NorthWestern provided, however, as between Seller and such Similarly-Situated
"QFs view PIJRPA as creating an entitlement rather than a competitive opportunity. Some large projects are
attempting to disaggregate into smaller projects that qualify for the standard offer rate Furthermore, QFs do not
recognize that intermittent resources are not the equivalent of resources that can be dispatched. Finally QFs seem to
believe that retail customers should subsidize their projects regardless of cost and that they should not be held to the
same commercial terms as other suppliers. Additionally, the Commission has substantially contributed to the
problems. For its part, the Commission has failed to distinguish and establish QF rates that consider the availability
of energy or capacity under peak periods, the expected reliability of the project, and the ability to dispatch the QF
(among other factors), as required by 18 CFR Sec. 292.304(e)(2). lii addition, the Commission has adopted
administrative rules that are inconsistent with federal regulations; under preemption principles, where compliance
with both is an impossibility, the federal regulation preempts the state regulation, and the state regulations are
invalid." Reply Comments, p.2.

6. The federal and state regulations that NWE seeks to have interpreted as they may
impact its ability to include the new curtailment language in its QF contracts are 18 C.F.R.
292.304(f) and ARM § 38.5.1903(1).
18 C.F.R. 292.304(f) provides:
Periods during which purchases not required. (1) Any electric utility which gives
notice pursuant to paragraph (1)(2) of this section will not be required to purchase electric energy
or capacity during any period during which, due to operational circumstances, purchases from
qualifying facilities will result in costs greater than those which the utility would incur if it did
not make such purchases, but instead generated an equivalent amount of energy itself.
(2)Any electric utility seeking to invoke paragraph (f)( 1) of this section must notify, in
accordance with applicable State law or regulation, each affected qualifying facility in time for
the qualifying facility to cease the delivery of energy or capacity to the electric utility.
(3)Any electric utility which fails to comply with the provisions of paragraph (1)(2) of
this section will be required to pay the same rate for such purchase of energy or capacity as
would be required had the period described in paragraph (f)(l) of this section not occurred.
(4)A claim by an electric utility that such a period has occurred or will occur is subject to
such verification by its State regulatory authority as the State regulatory authority determines
necessary or appropriate, either before or after the occurrence.
ARM § 38.5-1903(l) provides:
Each utility shall purchase any energy and capacity made available by a
qualifying facility, except that a utility is not obligated to make purchases from an interconnected
qualifying facility:
(i)during system emergencies if such purchase would contribute to the
emergency;
(ii)as stipulated in the contract between the utility and the qualifying facility;
(iii)it due to operational circumstances, purchases from a qualifying facility will
result in costs greater than those which the utility would incur if it did not make such purchases.
This provision is only applicable in the case of light loading periods in which the utility must cut
back base load generation in order to purchase the qualifying facility's production followed by an
immediate need to utilize less efficient generating capacity to meet a sudden high peak. Any
utility seeking to invoke this exception must notify each affected qualifying facility and the
commission one month prior to the time it intends to invoke this provision. Failure to properly
notify the qualifying facilities and the commission or incorrect identification of such a period
will result in reimbursement to the qualifying facility by the utility in an amount equal to that
amount due had the qualifying facility's production been purchased.

7.NWE asserts that the number of hours in which it experiences surpluses is
increasing, stating:
As NorthWestern enters into more PPM with QFs, the occurrence of the
operational circumstances described in the preceding paragraphs becomes more frequent and
resulting effects potentially greater.. .Petition, p.4.
NWE did not attempt to quantify the cost and rate impacts of these alleged
conditions.
8.NWE argues that its proposed curtailment language conforms closely to the language
of the federal regulation, that FERC has not rejected similar language in various dockets where
contracts containing that language has been before that Commission (although that language was
not directly addressed by FERC), and that no Montana cases compel the rejection of the
language.
9.Rather than list the arguments of each of the commenters, the Commission will
summarize the arguments that have been presented against the proposed curtailment language.
a.The relevant cost comparison under the CFR is between the QF price and the
operating cost associated with curtailment plus the restart cost of a baseload unit. The CFR
authorizes curtailment only for operation and not for economic reasons, and does not relieve the
utility of its obligation to purchase QF output in the situation described by NWE.
b.The proposed language is too broad in scope and would confer excessive discretion
on NWE to impose curtailments based on a range of economic circumstances. Further, it is not
clear whether NWE would curtail its own generation so that all providers would be treated
similarly.
c.The right under the proposed curtailment language to refuse to purchase QF output
following notice to the QF is fundamentally at odds with the obligation to purchase embodied in
the Public Utility Regulatory Policies Act of 1978 (PURPA) and state law. The proposed
language would authorize economic curtailment when market prices are low, and the resulting
uncertainty would prevent QF developers from arranging affordable financing. NWE's
application for approval of the Spion Kop wind project (Docket No. D2011.5.41) provides that
NWE would enter a PPA as buyer if the Commission declines to preapprove the project;
Exhibit 505
GNR-E-1 1-03
D. Reading: Simplot,
Exergy, Clearwater
Page 4
DOCKET NO. D2011.757, ORDER NO. 7172 5
however, that PPA does not contain a parallel curtailment provision to that proposed here by
NWE. The proposed language has no upper limit on the number of hours that curtailment could
be imposed, rendering a QF's revenue stream something of a guessing game.
d.NWE argues that the governing federal and state regulations, adopted during a period
of vertical integration, must be construed in light of today's circumstances, when NWE relies
heavily on PPAs from a variety of sources. However, the context of both the FERC and PSC
rules is clearly reduction and restart of baseload power units. If NWE wishes to see those rules
adapted to its changed environment, its remedy is to pursue rulemaking rather than advocating
strained interpretation of these regulations.
e.The proposed curtailment language is excessively broad and would allow NWE to
curtail QF ouput at any time the QF cost exceeded that of power available from the market. The
lack of an upper bound on the potential hours to be curtailed would make financing of a QF
seeking to contract with NWE impossible. Clear guidelines are needed defining conditions such
as "light load" and "sudden high peak," and, absent those guidelines, contracts now in
negotiation should proceed without the disputed language. NWE has contracted for substantially
more energy than it requires to serve its normal load. With 30 MW of new wind QFs having
been added recently, the addition of another 20 MW that will take NWE to the Commission's 50
MW "cap" will hardly burden NWE's shareholders or its customers. NWE's reliance on
California authority is misplaced; California's curtailment cases compare the cost of self-
generation to the cost of QFs—there is no comparison to market purchases. Curtailment policy
should apply equally to the utility and its resources that are supplied under PPAs and to QFs.
Spion Kop, if it is approved, should live by the same rules NWE has proposed for other
resources. QFs should be allowed to obligate themselves to a legally-enforceable obligation that
does not include the arbitrary curtailment language; NWE's insistence on this provision prevents
the QF from exercising that right.
f.NWE consistently attempts to limit its requirement under PURPA to purchase
electricity from QFs; this filing is another effort to introduce uncertainty that will compound the
difficulty already facing QFs in obtaining financing. NWE seeks to incorporate cost analysis for
intermediate load plants, but that term is not defined in federal or state rules. While hydropower
is much more predictable than the output of wind facilities, NWE's language would nonetheless
extend operational limitations to that type of plant without justification.

g.In framing its rules FERC recognized that avoided costs would vary from time to
time. NWE ignores that fact by picking a pafticular operational circumstance when avoided
costs are low, and then seeks unbridled authority to curtail QFs during those hours. This
approach finds no support in the language of PTJRPA, in the rules implementing PURPA, or in
precedent. The term "operational circumstances" was intended to be narrowly construed to
include the situation where baseload generation must be reduced and cannot be brought back to
its former output level in a timely manner. The full scope of NWE's intent is not clear because
its proposed curtailment language is so general in nature. Because of the uncertainty regarding
application of the language, a QFs revenue stream will not be predictable.
h.In fact, one QF, Horseshoe Bend, accepted curtailment language very similar to that
proposed by NWE in this case. That contract covers sales to NWE in the summer of 2011. In
the month of July, N 1NE invoked curtailment in 50 separate hours, only a few of which would
normally be considered "light load hours." NWE has not provided Horseshoe Bend with
documentation of the basis for its curtailments. The NWE language is excessively broad and
provides NWE with significant discretion, while providing QFs With no assurance that similarly-
situated generators will be treated identically.
i.The proposed curtailment language allows NWE to curtail deliveries in its sole
discretion so long as similarly situated suppliers are treated in a non-discriminatory nature. This
provision would render NWE's purchase obligation under PURPA and under Montana law
meaningless. Similar curtailment language sought by The Montana Power Co. was rejected by
the Commission in 1983. Further, this Commission has held that relative rate certainty is
essential. Future revenue streams must be predictable if new QF projects are to have access to
capital. Finally, this issue must be resolved quicidy if current federal programs that encourage
QF development are to be available to developers, since projects must be substantially advanced
in development in 2011 if federal subsidies are to be secured.
10. NWE's Reply to the Initial Comments of the QFs seeks to portray NWE as the
protector of its customers. NWE acknowledges that those opposing the Petition forcefully
present their interests and needs, but NWE believes that they ignore the delicate balance that
must be achieved between QF interests and PURPA's requirements for consumer indifference.
NWE is a voice for the utility's interests and also for its retail customers' interests. Reply, p. 3.

ANALYSIS
11. The heart of NWE's legal argument is that its proposed curtailment language is
consistent with 18 CER 292.304(f)(I)? This comparison is presented at pages 4 and 5 of the
Reply. NWE relies on the parallel language of the two provisions which states that the purchase
obligation can be avoided during periods when "operational circumstances" cause costs greater
than those the purchasing utility would incur if not for the QF deliveries. However, in advancing
this argument, NWE wholly ignores several key points. First, the preamble of the federal rule
upon which NWE rests its case states that
This section was intended to deal with a certain condition which can occur during light
loading periods. If a utility operating only base load units during those periods were
forced to out back output from the units in order to accommodate purchases from
qualifying facilities, these base load units might not be able to increase their output level
rapidly when system demand for power later increased. As a result, the utility would be
required to utilize less efficient, higher cost units with faster start-up to meet the demand
that would have been supplied by the less expensive base load unit had it been permitted
to operate at a constant output. 45 Fed. Reg 12227 (Februrary 25, 1980)
The Commission's rule at issue contains language that closely parallels the FERC preamble.
ARM § 38.5A903(l), states that:
(iii) if, due to operational circumstances, purchases from a qualifying facility will result
in costs greater than those which the utility would incur if it did not make such purchases.
This provision is only applicable in the case of light loading periods in which the utility
must cut back base load generation in order to purchase the qualifying facility's
production followed by an immediate need to utilize less efficient generating capacity to
meet a sudden highpeak.
Therefore, the Commission concludes that there is no conflict between its rule and that of FERC.
NWE's reading of the federal and state rules, and its proposed curtailment language, must be
rejected. Even if the FERC's rule and its intent were as NWE wishes, the ARM clearly prohibits
NWE's language. Further, federal law authorizes the State to adopt its own requirements in this
3 The language of the FERC regulation that NWE relies on reads as follows: "Any electric utility which gives notice
pursuant to paragraph (f)(2) of this section will not be required to purchase electric energy or capacity during any
period which, due to operational circumstances, purchases from qualifying facilities will result in costs greater than
those which the utility would incur if it did not make such purchases, but instead generated an equivalent amount of
energy itself"

Beginning on or before the date one year after any rule is prescribed by the commission
under subsection (a) of this section or revised under such subsection each State
regulatory authority shall, after notice and opportunity for public hearing, implement
such rule (or revised rule) for each public utility for which it has ratemaking authority.
16 USC Sec. 824a-3(f)(1)
The Montana Legislature has authorized the Commission to "adopt rules further defining the
criteria for qualifying small power production facilities, their cost-effectiveness, and other
standards." Sec. 69-3-604, MCA.
12.In light of the foregoing, the Commission finds that NWE's proposed curtailment
language is not authorized by state or federal law, and NWE. is prohibited from demanding that
new QFs with whom it is negotiating accept such language as a pre-condition of contracting with
NWE for the sale of their output to the utility. If market conditions occasionally result in prices
less than NWE's tariffed avoidable costs, that is not in itself a sign that the principle of consumer
indifference is unlawfully being violated—no more than if a long-term acquisition of NWE's
own were to result in a fixed-and-variable cost-per-unit which were higher than prices available
on the spot market. Sec. 18 CFR 292.304(b)(5).
13.It is also important to note that NWE's QF tariffs make no provision for the
reduction of purchase volumes for curtailments sought by the buyer. For example, NWE
Schedule No. QF- 1 provides that the specified purchase prices, Options 1 (a)-(c) provide that the
full price will be paid for deliveries at "all hours"; Option 2(a) refer to purchases during "each
hour", Option 2(b) refers to metered kWh delivered to the Utility; and Option 3 applies the
purchase price to deliveries at "all hours." The Commission concludes that NWE is bound by
the provisions of its tariffs, as well as State and Federal rules, as discussed above.
14.NWE' s Reply Comments contain several arguments that warrant a response.
NWE's critique of the Commissions system of QE regulation ignores NWE's obligation to
advocate and support avoidable cost calculation methods and tariff rates with high quality
evidence that will withstand critical scrutiny. If the avoided cost of intermittent resources is less
than the rates contained in MPSC tariffs, NWE is not lacking in opportunities to prove that case.
When NWE's electric power supply plans regularly include wind resources within the preferred
portfolios, NWE is not advocating a limit on wind procurement. Indeed, NWE recently
Exhibit 505
GNR-E-1 1-03
D. Reading: Simplot,
Exergy, Clearwater
Page 8
DOCKET NO. D2011.7.57, ORDER NO. 7172
advocated in Docket No. 112010.7.77 a separate rate for wind QFs of 10 MW or less. The
Commission agrees with commenters that it is not clear why the "back up" PPA for Spion Kop
(the contract under which NWE would secure wind if its own acquisition of the wind farm is
rejected) does not contain a curtailment provision like that at issue here.
15.A sound approach to implementing PURPA is particularly important now as
NWE transitions from a default supplier in a deregulated retail market to a vertically integrated
utility with an electricity supply monopoly. PURPA requires a neutral playing field for qualifying
facilities and facilities that NWE may prefer to own. So long as PURPA is law, the Commission
will enforce it. While rejecting much ofNWFs criticism of its approach to implementing
PURPA, the Commission is open to working with NWE and others to improve that approach. To
the extent NWE has ideas in this regard it should proactively offer them in its biennial QF tariff
filings or petitions for rulemaking. These are the proper places for reform, not a petition for
declaratory judgment seeking to extend an existing rule to a situation that clearly does not apply.
16.As to NWE' s argument that comments of QFs should not have been solicited in
this proceeding (Reply Comments, pp. 6-9), counsel for NWE is well aware that receipt of
comments from interested parties in declaratory ruling proceedings has been the longstanding
practice of the Commission. Presumably, the rule requiring the petitioner seeking a declaratory
ruling to list "the name and address of any person known by petitioner to be interested in the
requested declaratory ruling" does so precisely so that the views of those persons can be
obtained. Sec. 1.3.227(2)(h), ARM. This practice was followed in a recent NWE declaratory
ruling request involving the Turnbull Project. Docket No. 1)2009.11.151. Finally, the
Commission, in designing its procedures, is obligated to
• . .include a method of affording interested persons reasonable opportunity to submit data,
views, or arguments, orally or in written form, prior to making a final decision that is of
significant interest to the public. Sec. 2-3-111, MCA.
The solicitation of comments from interested parties in this proceeding is necessary to comply
with the Commission's statutory obligation to provide a meaningful opportunity for public
participation as required by statute.

DISSENT OF COMMISSIONER
BRADLEY A MOLNAR TO ORDER NO. 7172
INTRODUCTION
On July 8, 2011, the Montana Public Service Commission (Commission) received a petition
from NorthWestern Energy (NWE) seeking declaration of proposed curtailment language NWE
proposes for new Qualifying Facility (QF) contracts. They offered ARM 38.5.1903(1) and
C.F.R. 292.304(f) as proof of their capacity to include curtailment language.
On September 1, 2011, the Commission, without a public hearing, voted 3-2 to reject NWE's
proposal to include in future QF contracts language giving the ability to curtail purchases when
market conditions (including light load hours) are such that certain QF purchases are not
necessary so the energy must be sold at a loss. This is a continuation of the Commission's
economic assault on customers of regulated utilities. Using tortured logic the Commission has
consistently ignored the plain wording of federal and state consumer protections designed to
allow "market ready" small generators into the regulated market without consumer harm. I
firmly believe those outside the narrow band of special interests profiting from below costs sales
would agree this ruling ignores/defies various ARMs and laws in order to promote various
industrial and political agendas.

ANALYSIS
One of the first issues was whether the various commenters should have been allowed to
comment. I concur with staff, indeed they should be allowed to comment. However, their
comments did not stick to the question of curtailment language but went to financing
considerations. Unsupported/undocumented discussions on impacts on unnamed credit sources
should never have been iii our legal conclusions.
The only question is whether NWE "shall not be obligated to accept or pay for Energy from
Seller during any period in which, due to operational circumstances, the acceptance 'of Energy
from Seller and Similarly-Situated Suppliers of energy to NorthWestern is expected to result in
NorthWestern system costs greater than those which NorthWestern would incur if it did not
accept such deliveries...," as well as, is there a legal basis for or against the conclusion?
This is not difficult. In multiple dockets, final orders and discussions, Commission stafl
Commissioners, and the Montana Consumer Counsel (which ignored this opportunity) have all
alluded to the overarching PTJRPA dictate that while the goal is to provide an opportunity for
small generators to sell their product consumers must be made "indifferent." This is referenced
on P.6 Para 10 and denigrated away with the use of "occasionally" in lieu of the more accurate
"predictably" which goes fo the need for curtailment. Men of good heart could not argue that
buy high/sell low (and stick consumers with the difference) comports to this mandate.
The referenced ARM 38.5.1903(l)(ii), clearly states that curtailment is allowed if stipulated in
the contract, and 18 C.F.R. 292.304(f) seems to mirror the requested language in the NWE
proposed language and gives all the authority needed without PSC preapproval. The request for
a declaratory ruling seems beyond an abundance of caution and causes one to look for other
rationale. ARM 38.5.8204(a) also speaks to this issue by clearly stating that "customers should
be supplied with reliable, stably and reasonable priced (electricity) at the lowest long term price."
After one notes that consumer indifference is our guide under federal and state policy one should
note the lack of mandated concern for financial markets and access to federal subsidies. The

mandate of "reliability" was addressed on page P.8 Para 12 where it was labeled an "unavoidable
complexity" then deleted. The proposed language avoids much of the complexity.
ARM 38.5. 8219 plainly mandates the mitigation of risk through analysis of (d) competitive
prices and (i) contract terms and conditions. This is plainly a mandate to NWE. The,
Commission is supposed to enforce ARM 38.5.8219, not ignore it. The Commission opted to
shift the risk from QF financiers and QF developers to consumers. This is outrageous,
undefendable and illegal.
The ARMs provide procedure to implement the law. MCA 69-8-419 instructs the utility at
(2)(a) to provide adequate and reliable electricity supply service at the lowest long-term total
cost, (c) identify and cost effectively manage and mitigate risks related to its obligation to
provide electricity supply service, and (d) use a competitive procurement process whenever
possible.
The Commission's 3-2 vote on the issue of economic curtailment is direction to NWE to violate
federal and state laws and policies leading to extreme regulatory uncertainty and legal risk as
NWE's legal obligations are not lifted by rogue Commission actions. Now that NWE has raised
the issue they are obligated to achieve resolution.
GENERAL
The constant references to Spion Kop for justifications area major concern. This order dealt
strictly with curtailment language in future QF contracts. Spion Kop is not a QFso any
analogies are immaterial as they are not covered in, nor is there a mandate from, PURPA. Rather
it seems like childish finger pointing after a playground scuffle wherein justification seems to
hinge on, "Oh yeah, how about him"; rather than a discussion of the point in controversy.
More importantly Spion Kop is a docketed matter. Arguably we have pre-approved non-
curtailment language for Spion Kop before the hearing.' Never during my tenure have we used a
docketed item for a point of discussion outside the docket. Rather we have been consistently

warned about discussing dockets or possible findings. Perhaps the entire Commission now needs
to consider recusal on the Spion Kop docket.
On page nine Commissioner Kavulla once again uses the negative attention seeking device that
NWE should have chosen a venue and time more to his personal preference. That seeking a
declaratory ruling not fitting his unpublished time frame is somehow unjustified, worthy of his
contempt and cause for denial.
Having read and reread the ARMs concerning the request for declaratory rulings I find zero
references to preferences for "biennial QF tariff filings" OE "petitions for rule makings." Nor are
there any such challenges in the evidentiary record. There are only requirements for filings, not
a list of mandates for venue shopping prior to a request for a declaratory ruling. How our legal
department allowed these unfounded, undocumented, unsubstantiated mutterings to be included
in a legal document is cause for introspection.
Recently, at a location near Red Lodge, MT, Chairman Kavulla lambasted Southern Montana
Electric (SME) for purchasing power then, because of an over-generation event, selling it at a
loss and passing the stranded costs onto consumers. This was witnessed by several utility
personnel present (perhaps the reason for this request) and reported in the press. Now he argues
that proper policy is that planned over-generation with resulting below cost sales should be a
stranded cost borne by NWE customers.
Such hypocrisy spouted by the Chairman generates the perception of regulatory uncertainty and
predictably higher costs (rather than lowest costs possible) for regulated utility and co-op
customers alike regardless of his forum.
CONCLUSION
NWE has specific authority to contract for QF power with curtailment language especially
during light load hours. And they have federal and state statutory mandates to curtail on an

economic basis to maintain consumer indifference. This was an unnecessary but interesting
exercise that perhaps had more to do with SpiOn Kop than Two DoL
I am perplexed as to why the Montana Consumer Counsel opted to be silent on this issue.
Perhaps they have given up on the Montana Commission and are picking their battles. Perhaps
they should intervene and ask for reconsideration and possible judicial review. Perhaps.
Over the last several decades too many Montana Commissioners have seen themselves as
political engineers or environmentalists with an agenda dedicated to servicing the desires of QF
developers rather than to consumer indifference and have, or rather continue to cost consumers
literally hundreds of millions of dollars and put a strain on our economy. The findings of Order
7172 are a continuation of that sad heritage. There is no interpretation of any ARM or any MCA
cite, made by myself, NWE, or any intervenor, that allows the purposeful over generation of
electricity for the purpose of below costs sales from any type of generation.
While the Commission may have, correctly or incorrectly, discouraged certain specific
curtailment language for future QF contracts NWE still has a legal obligation to implement
curtailment to insure consumer indifference and statutory compliance. Hopefully a more
populist future Commission shall hold them to it or, if the courts have not acted, help them
implement it.

Contracts with Qualifying Facilities )
CONCURRING OPINION OF
COMMISSIONER TRAVIS KAVIJLLA
The current Qualifying Facility regime is by no means desirable. When NorthWestern Energy
Corp. ("NorthWestern" or "applicant" or "petitioner") files its resource procurement plan, it sets
in motion another docket whereby the Commission pursuant to PUTRPA and Montana law plays
market maker and sets out to do the impossible: creating a durable rate which reflects the
"avoided cost" of energy over a short and long term. As the last few years make clear, however,
there is nothing consistent or durable about the wider economy to whose vicissitudes the energy
market is subject. A meaiingful avoided cost is difficult to concoct if it is only being revised
biennially or at an even longer interval. Similarly, it is difficult to ignore the fact that this
Commission's rules have created a mode of political economy where nearly all QFs are built to a
scale (10 aMW) which is decreed as an upper limit to a QF standard-offer contract by the
Commission's administrative rules. Perhaps the eventual answer lies in taking this Commission
out of the market-making game and leaving that role to the market itself via processes which do
not revolve around fixed and inflexible prices like requests for proposals. None of the foregoing
is directly at issue in this docket, but is so inexorably linked to any matter touching upon QF
policy that it deserves enunciation as a preface.
At issue here is the applicant's attempt to use what is essentially a dead letter of the
Commission's administrative rules, explicitly intended for a utility which owns a considerable
amount of base-load generation, to introduce an utterly novel concept into the realm of PURPA-
based regulation as it exists in Montana: one which is neither countenanced by the clear language
of the governing tariff, which states that a QF shall be paid for "all hours" of generation, nor by a

considered reading of the rule itself; nor, more quaintly, by a rudimentary sense of fair play and
nondiscriminatory access which animates Montana's implementation of PURPA.
While sensitive to the outcomes wrought upon the system by an antiquated regime of QF
regulation—which, inopportunely, NorthWestern seeks to exploit in this petition, rather than
alter in a rulemaking—the Commission should try to enforce the letter and spirit of the law to the
best of its ability. This includes an attempt to maintain impartiality between the assets
NorthWestern owns or intends to own, and of those with whom it is entering into agreements.
That guideline, and not an unremitting embrace of the status quo, is the spirit in which this
Order, I hope, will be read.
The Dissent to this Order requires a few points of correction.' First, it confuses what is permitted
under state and federal rules' existing curtailment language by conflating "operational
conditions"—when curtailment is explicitly contemplated—with "market conditions." One is not
the other. Market conditions, by which I mean a more expansive notion than the truncated view
of spot prices the Dissent brooks, are anticipated by the avoided-cost tariffs. This Commission's
tariffs put forth a multifaceted calculation of avoided cost resulting in three options. One option
is premised upon a price available at market, another upon the acquisition of a long-term base-
load asset (pegged, in the last tariff, to Coistrip W, an avoided cost essentially established when
the Commission, including the dissenter, voted to allow the utility's acquisition of it), and the
third is based upon the cost of a long-term wind asset whose acquisition to comply with public
policy is anticipated by the procurement plan. The asset being avoided, in other words, is
different in term or fuelstock or uncertain other costs like wind integration in each of the three
options, and therefore results in different avoided-cost rates. The Dissent should, but does not,
ask itself: Could the prevailing low market prices be secured over a 25-year period? Obviously
not
The Dissent is accordingly confused about what is meant by "consumer indifference." The
consumer is indifferent to whether the utility pays a spot price to a QF generator equal to what it
'Indeed, the Dissent requires more than a few points of correction. But in the interest of brevity, this Concurring
Opinion, because the Dissent is unintelligible in parts, will not attempt to impute a meaning to its language.

would pay at the spot market. But the consumer also is indifferent whether NorthWestern buys
from a coal-fired plant in which the utility owns a stake versus purchasing from a different
generator—if the price paid on- and off-peak is the same. So, too, does the consumer not care
whether NorthWestern complies with a public-policy requirement by obtaining its own wind
asset, signing a non-QF power-purchase agreement with a wind company, or signing to buy with
a small QF. The avoided cost and terms and conditions of a QF contract should, then, reflect as
much as possible those which prevail with respect to non-QF generators or purchases: that is the
concept of indifference which appears to elude the Dissent.
There are numerous other errors in the Dissent. It miscoinprehends the nature of this year's
overgeneration event and what it does and does not mean for the state's wholesale co-ops and
utilities. It implies that a declaratory judgment's issuance in the absence of a public hearing is
somehow improper. It pretends that the Order's "legal conclusions" are premised on a QF's
concern over obtaining financing, when that point was merely reiterated within the Order, not
advocated by it, as a comment the Commission had received (Order, p.5). Insidiously, even
while inveighing against the "regulatory uncertainty" to which the Order will supposedly
contribute, the Dissent appears to encourage NorthWestern to violate the same Order.
At its core, the Dissent is schizophrenic. While calling for a less activist Commission—a notion
with which I am sympathetic—it forwards a vision of PURPA which goes far beyond the scope
of the petition and itself engages in a dismal activism which is totally at odds with the clear
meaning of the law and with the reality of electrical markets. Even while branding itself
"populist," ironically the only thing the Dissent would accomplish is to encourage monopolism
and set up a parallel set of rules which binds some but not others.
I CONCUR with the Order.

DEPARTMENT OF PUBLIC SERVICE REGULATION
BEFORE THE PUBLIC SERVICE COMMISSION
OF THE STATE OF MONTANA
IN THE MATTER OF the Petition of ) REGULATORY DIVISION
North Western Energy for a Declaratory Ruling )
on the Applicability of 18 C.F. R. § 292304(1) ) DOCKET NO. D201 1.7.57
and ARM § 38.5.1903(1) to Contracts with ) Qualifying Facilities ) ORDER NO. 7172a
ORDER ON RECONSIDERATION
1.The Montana Public Service Commission (MPSC or Commission) on September
13, 2011, issued Order 7172 (Order) rejecting the proposed contract curtailment language of
NorthWestern Energy (NorthWestern or NWE) and holding that the proposed language was
inconsistent with the rules of this Commission and the Federal Energy Regulatory Commision
(FERC) regarding qualifying facilities (QFs). Order, p. 8. On October 7, 2011, NWE filed a
Motion for Reconsideration (Motion).
2.MPSC denies the Motion for the reasons outlined below.
Background
3.The proposed NWE contract language is described in the NWE Petition, which
was filed on July 8, 2011. Order, pp. 2-3. That language is further explained in Exhibit C to
NWE's proposed QF contract. Although NWE did not supply the Commission with that Exhibit,
it was contained in the August 1, 2011, Comments of Hydrodynamics.
4.The Motion asks that the Commission address four issues on reconsideration, and
that it "identify each perceived shortcoming in North Western's curtailment proposal, along with
Exhibit 505
GNR-E-1 1-03
D. Reading: Simplot,
Exergy, Clearwater
Page 20
DOCKET NO. D2011.7.57, ORDER NO. 7172a 2
the specific legal basis for those conclusions, such that North Western can move forward on a
fully-informed basis." Motion, p. 12.
Issue 1 "[TI he Order's broad, sweeping rejection of North Western's curtailment
provision directly conflicts with a core requirement of PURPA—that a utility need not
purchase power from a QF when negative avoided costs would result..."
5.The Order at pages 7 and 8 compared NWE's proposed language to FERC and
MPSC rules and FERC discussion in the rulemaking process, emphasizing the limitation to
curtailment in which "operational circumstances" require cut backs of base-load generation
"followed by an immediate need to utilize less efficient generating capacity to meet a sudden
high peak." ARM Sec. 38.5.1903 (1), as quoted at Order 7172, p. 7. While already quoted at p.
7 of the Order, that language apparently bears repeating. The rule provides that a utility is
relieved of its obligation to purchase QF output
(iii) if, due to operational circumstances, purchases from a qualifying facility will result
in costs greater than those which the utility would incur if it did not make such purchases.
This provision is only applicable in the case of light loading periods in which the utility
must cut back base load generation in order to purchase the qualifying facilities
production followed by an immediate need to utilize less efficient generating capacity to
meet a sudden high peak.
6.NWE's proposed language is inconsistent with and far exceeds the scope of this
rule. NWE's contract language, including Exhibit C, describes a planning activity that the utility
will conduct to determine whether a surplus exists. Total load is compared to total resources. If
a surplus exists in light load periods, the utility reserves the right to declare a surplus and allocate
curtailments in any manner it determines appropriate. By contrast, an operational circumstance
(as contemplated by the rule) would most likely be a plant-related occurrence.
7.NWE stresses a general formulation by FERC of its desire to avoid negative
avoided costs (and resulting payments by QFs to the utility) from the FERC rulemaking Order
(Motion, p. 5), but ignores FERC's rule that acknowleges that long-term avoided costs will at
times exceed prices from the market or contracts of different terms. 18 CFR Sec. 292.304 (a)(5).

GNR-E-1 1-03
D. Reading: Simplot,
Exergy, Clearwater
Page 21
DOCKET NO. D2011.7.57, ORDER NO. 7172a 3
Issue 2 "[Tlhere is some indication that the Order is based on a legal conclusion that
PURPA restricts the definition of baseload resources to physical assets that are owned by
North Western—to the exclusion of long-term PPAs."
8.NWE believes that the Order suggested that QF curtailment rules only apply if
base load resources are owned by the utility. To the extent there is an ambiguity, the MPSC
notes its view that, under the current rules, curtailment may legitimately be triggered when the
utility's resources consist of a mix of owned and purchased resources.
9.Whether baseload resources are owned or purchased, this Commission's rule
provides that necessary preconditions would still apply. In the case of a purchase agreement,
necessary preconditions would include a "take or pay" provision, high start-up costs, and a lag in
re-start times. Then other peak-load contracts would have to be relied upon in the interim while
the base-load contracts were curtailed or "cut back" from generation, awaiting start-up. If such a
situation does exist, necessitating the curtailment which NWE is arguing for, then NWE should
make the Commission aware of it. The rule, however, does not contemplate curtailment due to
excess purchases or for the sake of achieving a lower total cost from the resource stack resulting
from market conditions, as discussed in response to Issue 1.
Issue 3 "[To] the extent the Order may reflect commenters' allegations that
NorthWestern's proposal seeks 'excessive discretion'. ..or 'unbridled authority'..., the
Order is based on groundless criticism."
10.NWE is encouraged to review its proposed curtailment provision, which contains the
following language:
During periods in which North Western is purchasing energy both from Seller and
Similarly-Situated Sellers, the implementation of any curtailments of delivery of energy
is subject of the sole discretion of NorthWestern...
Exhibit 505
GNR-E-1 1-03
D. Reading: Simplot,
Exergy, Clearwater
Page 22
DOCKET NO. D2011.7.57, ORDER NO. 7172a 4
The provision continues by alluding to the language of Exhibit C to the contract. Exhibit
C provides that:
A determination of the amount of scheduled energy purchases to be curtailed and the
Sellers to whom the curtailment procedures will apply is subject to the sole discretion of
NorthWestern....
The broad scope of discretion NWE attempts to reserve to itself (as well as the potential
for disparate treatment of QFs) speaks for itself, and could result in discrimination among QFs
that is inconsistent with federal and state rules.
Issue 4 "[T]he Order incorrectly concludes that NorthWestern's Schedule No. QF-1
somehow overrides the curtailment regulations of both FERC and this Commission."
11.The MPSC agrees that the QF- 1 tariff is not controlling; however, it suggests that
NWE should modify it tariff to eliminate any inconsistencies.
Conclusion
12.The curtailment provision that NWE asks the Commission to authorize is at odds
with the utility's own practice in light of some very recent history. NWE did not insist on
curtailment language in the first three wind QF contracts which it signed in the past twelve
months (Musselshell I and 2 and Gordon Butte). Nor did NWE insist on inclusion of
curtailment language in its Power Purchase Agreement with Compass Wind. Docket No.
2011.5.41. This contract also provided the price point (i.e., the proposed avoided cost) which the
utility asked this Commission to use as the premise for rates offered to QF wind projects.
Docket No. D2010.7.77. Then, in July of this year, QF curtailment was advanced with rhetorical
urgency with the filing of this proceeding and in NWE's most recent Motion. Whatever NWE's
motives, its actions are inconsistent with its rhetoric. For this Commission to approve this about-
face in policy would be inconsistent with the regulatory objective of providing consistent
treatment to entities that are similarly-situated.

rectify problems that it perceives in QF policy.

REQUEST FOR PRODUCTION NO. 2: Please provide copies of all documents
related to Idaho Power's acquisition of RECs from existing or proposed QF PRUPA [sic]
projects.
RESPONSE TO REQUEST FOR PRODUCTION NO. 2: Idaho Power objects to
this Request on the grounds of relevance. The Direct Testimony of Lisa A. Grow
submitted in this proceeding specifically states, ". . . the Company has no specific
request of the Commission in this regard [i.e., related to RECs] at this time." Grow
Testimony at p. 14, 11. 6-8. Since Idaho Power has no specific request regarding RECs
in this proceeding at this time, questions related to RECs are irrelevant and beyond the
scope of this docket.
Idaho Power further objects to this Request as it is overly broad and would be
unduly burdensome for the Company to provide the information requested.
In addition, some of the requested material is or may be privileged and protected
by the attorney-client privilege as well as the attorney-work product doctrine.
Idaho Power does not specifically seek to acquire RECs from existing or
proposed qualifying facility ("QF") Public Utility Regulatory Policies Act of 1978
("PURPA'3) projects. Idaho Power includes the environmental attribute language below
in initial Idaho draft PURPA agreements supplied to proposed PURPA projects.
Under this Agreement, ownership of Green Tags and
Renewable Energy Certificate (RECs), or the equivalent
environmental attributes, directly associated with the
production of energy from the Seller's Facility sold to Idaho
Power will be governed by any and all applicable Federal or
State laws and/or any regulatory body or agency deemed to
have authority to regulate these Environmental Attributes or
to implement Federal and/or State laws regarding the same.

During the process of negotiating the draft PURPA agreements into final form,
Idaho Power and some counterparties have negotiated modifications to the above
language that has resulted in either (1) Idaho Power owning 50 percent of the
environmental attributes created by the project for the entire term of the Firm Energy
