COMMENTS OF THE
COMMISSION STAFF
COMES NOW the Staff of the Idaho Public Utilities Commission, by and through its
Attorney of record, Weldon B. Stutzman, Deputy Attorney General, and in response to the Notice
of Application and Notice of Modified Procedure issued in Order No. 31064 on
April 27, 2010, submits the following comments.
BACKGROUND
On April 15, 2010, Idaho Power fied an Application to implement its Power Cost
Adjustment (PCA) rates effective June 1, 2010 through May 31, 2011 and to change base rates.
The Application states that the proposed PCA computation results from a Stipulation approved by
the Commission in Order No. 30978, Case No. IPC-E-09-30 issued January 13,2010. That
Stipulation provides for a sharing between customers and Company shareholders of any PCA
revenue reduction that results from this case. The Stipulation provides that PCA rates wil be
reduced by the full calculated amount and that base rates will be increased in an amount that
STAFF COMMENTS 1 MAY 18,2010
partially offsets the PCA decrease. Idaho Power's filing calculates the PCA revenue reduction to
be approximately $146.7 milion and the base rate increase to be approximately $88.7 milion.
The net customer benefit is approximately $58 milion which produces an average decrease in
rates of 6.47%. However, due to the fact that PCA rate changes are spread on an equal cents per
kWh basis, some customer class rate changes vary widely from the average percentage.
IDAHO POWER COMPANY'S FILING
The Power Cost Adjustment (PCA) Mechanism
In general terms, the PCA is an anual symmetrical rate adjustment mechanism that
recovers abnormally high power supply costs from customers or credits customers with savings
when power supply costs are abnormally low. The PCA has three components that combine to
produce an anual PCA rate. The first component is the Forecast or Projection. The Projection is
an estimate of the difference between normal power supply costs embedded in base rates and the
coming year's power supply costs. The Company uses its Operating Plan to estimate the coming
year's power supply costs. The PCA amount is converted to a rate by dividing by energy sales. In
this fiing the Company calculates above normal power supply costs of $87.6 milion relative to
power supply costs contained in curent base rates and above normal power supply costs of $20.9
milion relative to power supply costs contained in proposed base rates. After PCA sharng, these
two amounts produce rates to recover projected above normal power supply costs of 0.5814 t/kWh
and 0.1404 t/kWh respectively. The Company proposes to update base rates and use the
0.1404 t/kWh as the new PCA projection rate component.
The second PCA component is the true-up. The true-up captures the difference between
the previous year's projection and actual power supply costs. If the Projection proved to be
100 percent accurate, there would be no true-up. The true-up amount is converted to a rate by
dividing by projected energy sales. Idaho Power calculates this amount and rate to be $11,963,777
and 0.0888 t/kWh.
The third PCA component is the true-up of the true-up or reconciliation of the previous
year's true-up. This component calculates the amount of the unecovered true-up. The previous
year's true-up amount is not precisely recovered due to actual sales being different from the
previous year's projected sales and due to the two-month lag between the end of the PCA
accounting year and the implementation of new PCA rates. Idaho Power calculates the
reconcilation ofthe true-up amount and rate to be $11,284,407 and 0.0838 t/kWh.
STAFF COMMENTS 2 MAY 18,2010
The combination of the three components produces a 2010/2011 PCA rate of 0.3130
t/kWh (0.1404 + 0.0888 + 0.0838). The use of the lower projection rate of 0.1404 t/kWh assumes
that Base Rates are updated in this case to include a new level of normalized power supply costs.
The Base Rate Increase
As previously mentioned the Stipulation accepted by the Commission in Order No. 30978,
Case No. IPC-E-09-30, provides for a base rate increase to include, among other things, increases
in normal Power Supply Costs that have occurred since the Company's last general rate case. The
Company's filing includes an increase in base rates of approximately $88.7 milion.
Case No. IPC-E-IO-01, Order No. 31042, caried over to this case the issue of the
appropriate level of Bridger coal costs to be included in base power supply costs and, therefore, in
base rates. The amount of base level Bridger coal costs included in the Company's calculations in
this case is the level the Company proposed in the previous case.
The Combined PCA and Base Rate Impact
The combined impact of the PCA rate decrease proposed by the Company and the base rate
increase proposed by the Company is shown on page 1 of Company Exhibit NO.2. The disparity
in customer class rate change percentages results from the equal cents per kWh rate spread of the
PCA decrease. High load factor customers get larger percentage decreases when PCA rates are
reduced just as they received larger percentage increases when PCA rates go up. PCA percentage
increases and decreases are relatively small for smaller, generally lower load factor customers. In
this paricular case two lighting classes, Schedule 15 - Dusk to Dawn Lighting and Schedule 41 -
Street Lighting, are proposed to receive net increases because the equal percentage base rate
increase is larger to them than the equal cents per kWh decrease from the PCA.
STAFF AUDIT AND ANALYSIS
A. The peA Forecast or Projection
As previously discussed, the projection is prepared using the Company's most recent
Operating Plan. The Operating Plan incorporates the most curent information available in each
update. An account by account breakdown of the Company's power supply forecast proposal is
shown on Attachment A to these comments. The char shows the amounts included in Base Rates,
Forecast amounts and the Difference. Account 555 - PURPA Purchases is shown separately from
other Account 555 Purchases because differences in PURPA Purchases are not shared, the entire
difference is passed on to customers.
STAFF COMMENTS 3 MAY 18,2010
Attachment B shows the Company (page 1) and Staff (page 2) PCA rate calculation.
Page 1, lines 1 through 15 shows the calculation of the Forecast Rate proposed by the Company.
Line 3 shows the forecast offset due to expected Hoku first block revenues. Line 4 shows an
expected reduction in power supply costs associated with the sale of Renewable Energy Credits
(REC) and S02 Emission Allowances. Line 6 shows the customer sharing percentage that is
applied to all power supply cost differences, except the difference in PURPA costs. Line 9,
Column (g), shows the forecast rate excluding the portion of the forecast rate associated with the
expected PURP A cost difference. This rate is 0.1319 t/k Wh. Lines 11 through 13 show the
calculation of the portion of the Forecast Rate associated with the expected difference in PURPA
costs. This rate is 0.0085 t/kWh. The two pars of the forecast rate combine to produce the
forecast rate shown on line 15,0.1404 t/kWh. Among other things, this rate reflects water
conditions that are expected to be well below normaL. Under this forecast methodology, Idaho
Power does its own water forecast; however, the Northwest River Forecast Center expects April
through July Brownlee Reservoir inflow to be 52% of normaL. Although this year's PCA rate is
proposed to be substantially lower than last year's PCA rate, power supply costs are projected to
be approximately $20 millon above normaL.
The Staff has reviewed the Company's Operating Plan based Forecast and believes that it is
reasonable. The forecast wil not be perfect but the difference between forecast and actual is trued-
up in the following year's PCA.
B. The peA True-Up
The PCA true-up captures the difference between actual and projected power supply costs
experienced in the past year. With some adjustments, this difference becomes the PCA true-up
deferral balance. This deferral balance divided by expected sales is known as the PCA true-up rate
component.
Lines 4 through 78 of Exhibit NO.1 to Idaho Power witness Scott Wright's testimony
calculate the true-up deferral amount. Attachment C to these comments is Staffs verification of
the Company's true-up deferral calculations. In Case No. IPC-E-08-19, Order No. 30715, the
Commission authorized Idaho Power to redistribute monthly base power supply costs in a specific
maner to meet some paricular needs of the Company. The monthly redistribution was to leave
anual base power supply costs unchanged, which it has. However, the redistribution caused
$215,027 of additional interest to be deferred. Attachment D is Staffs calculation of the true-up
deferral amount when base power supply costs are not redistributed. Line 60 in both Attachments
STAFF COMMENTS 4 MAY 18,2010
shows accumulated true-up interest. Attachment C interest is $265,945 and Attachment D interest
is $50,918. In Order No. 30715 when discussing "Forecast and Expense Distribution" the
Commission said:
The remaining issues addressed in the Stipulation do not affect the
overall PCA cost responsibilty between customers and shareholders.
Clearly the Commission envisioned no cost difference as a result of the redistribution.
Therefore, Staff proposes that the interest difference be removed from the true-up balance
proposed by the Company. The Staff shows the removal of the interest difference on
Attachment B, page 2, line 21, as par of Staf s true-up rate calculation.
This year's true-up calculation includes a negative Load Growth adjustment of
approximately $23.7 milion. Actual loads during the true-up year were below normal loads in 10
of 12 months. The total below normal load was 889,235 MWh. This represents a 5.6% load
decline. The adjustment is the product of the negative load growth and the load growth adjustment
rate (LGAR) of26.63 $/MWh. The LGAR is composed of the variable and fixed costs of
production embedded in base rates. When load grows the adjustment reduces power supply costs
to avoid double counting production costs. When load declines the adjustment reimburses the
company for lost fixed production costs and makes the Company whole with respect to variable
production costs. The result is that $21.3 milion (after Jurisdictional Allocation and PCA sharing)
has been added to the deferral balance for recovery from customers in this year's PCA. This
amounts to 51 % of the Company's request to recover approximately $41.9 milion in above normal
costs. Negative monthly load growth has previously been included in PCA calculations and is par
of the approved calculation methodology. Nevertheless, Staff is curently reviewing the
justification for the adjustment when load declines, and plans to meet with the Company to discuss
possible load growth adjustment modification. Staff is recommending no change to the load
growth adjustment amounts or methodology in this case.
To verify revenues and costs associated with Idaho Power's true-up deferrals, Staff
conducted an audit of actual revenues and expenses that occured durng the PCA year. These
revenues and costs included water lease expenses, fuel expenses for coal, fuel expenses for natual
gas, power sales and purchases, third party transmission expenses, Hoku First Block Energy
expenses, green tag Sales Credit (RECs), and Qualifying Facilties expenses. Staff also examined
the Emission Allowance Sales Credit passed onto customers in the true-up of the true-up, and the
Risk Management operating plan.
STAFF COMMENTS 5 MAY 18,2010
The following items are included in the PCA true-up:
1. Water Leases. The Company leases water for the production of power from several
entities. The increase or decrease in the water lease expense from base rates is included in the
PCA for recovery from or refund to customers. This year's PCA deferral balance includes actual
water lease expenses of $2,205,906 and the amount included in base rates is $67,519, with the
difference of$2,138,387 included in the deferral balance. This increase in water lease expenses
from base expenses is a cost to customers and is subject to jurisdictional allocation and sharing.
2. Fuel Expense - CoaL. A large portion ofIdaho Power's electricity comes from thermal
power produced from coal plants. The three coal plants that Idaho Power owns an interest in are
Bridger, Valmy and Boardman. The increase or decrease in the coal expense from base rates is
included in the PCA for recovery from or refund to customers. For the audit period of April 2009
to March 2010, the total coal expense for all plants in operation is $128,504,371. The total coal
expense included in base rates is $133,454,723. This year's PCA deferral balance includes a
difference between costs currently included in rates and actual costs of $4,950,352. This reduction
in coal costs from base costs is a benefit to customers and is subject to jurisdictional allocation and
sharing.
3. Fuel Expense - Gas. Idaho Power curently owns and operates gas-fired combustion
turbine generating plants at the Evander Andrews Power Complex (3 Danskin units) and Bennett
Mountain. These plants are both located at Mountain Home and account for 100% of gas usage.
For the audit period of April 2009 to March 2010 the total variable gas and gas
transportation expense for both complexes was $18,420,326. The total gas and gas transportation
expense included in base rates is $6,125,180. The increase or decrease in gas expense from base
rates is included in the PCA for recovery from or refud to customers. In this year's PCA deferral
balance, the additional gas expense that is included for future recovery from customers is
$12,295,146 and is subject to jurisdictional allocation and sharing.
4. Power Sales and Purchases. Staff reviewed the power purchases and sales in
conjunction with the Company's Risk Management Operating Plan. Staff analysis did not find any
transaction that was not reasonable or did not follow the Risk Management Committee's
recommendations. These transactions were made with an assortment of credit-worthy parners on
a timely basis, and there were no transactions conducted with an Idaho Power affiliate.
a. Power Sales. During the PCA year ending March 31, 2010, the Company sold
surplus power totaling $94,357,434. The total surlus sales included in base rates is $116,568,567.
STAFF COMMENTS 6 MAY 18,2010
The increase or decrease in the power sales from base rates is included in the PCA for recovery
from or refund to customers and is subject to jurisdictional allocation and sharing. Actual surplus
sales were less than base amounts by $22,221,133. This difference is a reduction of revenues to
the detriment of customers and is subject to jurisdictional allocation and sharing.
b. Power Purchases. During the PCA year ending March 31, 2010, the Company made
market purchases, excluding PURPA contracts. The actual amount is $83,632,863. The total
power purchases included in base rates is $57,231,921. Actual purchased power amounts exceed
base amounts by $26,400,942. This difference isa cost to customers and is subject to
jurisdictional allocation and sharing.
5. Actual Qualifying Facilties Purchases Including Net Metering and Raft River. A
Qualifying Facility (QF) is a generating facility which meets the requirements for QF status under
the Public Utility Regulatory Policies Act of 1978 (PURPA) and Par 292 of the Federal Energy
Regulatory Commission's Regulations (18 C.F.R. Par 292), and which has obtained certification
of its QF status. There are two types of QFs - cogeneration facilties and small power production
facilties. Qualifying Facilities are sometimes referred to as cogeneration/small power producers
or by the acronym CSPP.
A Cogeneration Facility is a generating facilty that sequentially produces electricity and
another form of useful thermal energy (such as heat or steam) used for industrial, commercial,
residential or institutional purposes, and otherwise meets the requirements of 18 C.F.R.
§§ 292.203(b) and 292.205 for operation, efficiency and use of energy output.
A Small Power Production Facilty is a generating facilty whose primary energy source is
renewable (hydro, wind, solar, etc.), biomass, waste, or geothermal resources, and that otherwise
meets the requirements of 18 C.F.R. §§ 292.203(a), 292.203(c) and 292.204. Small power
production facilities are limited in size to 80 MW, with the exception of certain types of facilties
certified prior to 1995 and designated as "eligible" under section 3(17)(E) of the Federal Power
Act (FPA) (15 U.S.C. § 796(17)(E), which have no size limitation.
For the audit period of April 2009 through March 2010 the actual QF expense is
$64,344,768. The QF expense included in base rates is $63,269,889. The increase or decrease in
the QF expense from base rates is included in the PCA for recovery from or refund to customers.
In this year's PCA deferral balance, the actual QF expense was more than the base QF by
$1,074,879. This amount is a cost to customers and increases the PCA deferral balance. PURPA
contracts are not currently subject to sharing. They are subject to jurisdictional allocation.
STAFF COMMENTS 7 MAY 18,2010
6. Third Pary Transmission. In Order No. 30715, Case No. IPC-E-08-19, the
Commission found that third-pary transmission costs that are incured in conjunction with market
purchases and sales should be tracked through the PCA like other variable power supply costs, and
that including the expenses in the PCA is a straightforward treatment of power supply costs that
fluctuate with power purchases and sales.
For the audit period of April 2009 to March 2010, the actual third party transmission
expense is $6,692,114. The Third Pary Transmission expense included in base rates is
$10,469,726. This year's PCA deferral balance includes a difference between costs currently
included in rates and actual costs of$3,777,612. Because the actual costs are less than the amount
included in base rates, this amount represents a benefit to customers. This benefit to customers is
subject to jurisdictional allocation and sharing.
7. Hoku First Block Energy. In Order No. 31042, Case No. IPC-E-I0-0l, the
Commission established the base level for net power supply for 2010. In this Order, the
Commission accepted the Staff s recommendation that the Hoku expenses be captured in the PCA,
and not in base rates for 2010. Therefore, the actual costs are included in the PCA deferral, and
there are not corresponding base level amounts of Hoku expenses. In this deferral balance, there is
a credit of $611 included in the deferral balance. This represents a benefit to customers and is
subject to jurisdictional allocation and sharing.
8. Green Tag Sales Credit. In Order No. 30818, Case No. IPC-E-08-24, the Commission
ordered that green tag sales benefits flow to customers, subject to jurisdictional allocations and
sharing. The amount included in the deferral balance is $665,788. This is a benefit to customers.
The true-up of the Deferral Balance is composed of the following items:

Deferral Balance $11,697,831
Staff Interest on the Deferral Balance $50,918
Deferral Balance (True-Up) $11,748,749
The Company-proposed true-up rate is 0.0888 t/kWh as shown on Staff Attachment B,
page 1, line 20. The Staff-proposed true-up rate is 0.0872 t/kWh as shown on Staff Attachment B,
page 2, line 20. The only difference is Staffs true-up interest adjustment.
C. The peA True-Up of the True-Up
The PCA reconciliation of the true-up amount is the difference between what was approved
to be collected or refunded when the PCA rate for last year's true-up was set and what was actually
collected or refuded. The amount represents the under or over recovery of the true-up amount
from the previous year due to a different amount of kWh being sold than was anticipated in the
rate design and the fact that the true-up period included only 10 months with the true-up rate in
place. The true-up of the true-up is a benefit to both the Company and customers because any
true-up over-collection is returned to customers, and any true-up under-collection is recovered by
the Company.
Included in this year's true-up of the true-up is the benefit to customers from the 2008-2009
S02 Emission sales. Per Order No. 30790, the Company recorded the proceeds from the sale of
the 2008-2009 S02 credits in the curent year's PCA. The Idaho Jursdictional portion of the S02
allowance proceeds, including interest but net of tax were recorded in the PCA deferral account
and included in the true-up of the tre-up section in the months of April 2009 and June 2009. The
total system S02 amount is $5,229,875 plus accrued interest. The Idaho jurisdictional amount
after jurisdictional allocation and sharing is $4,591,632. This is a benefit to customers.
Last year's unecovered true-up amount to be recovered in this case is approximately $11.3
milion. This amount is calculated on Company Exhibit No.1, lines 80 through 97. The Staff
calculates the same amount on Attachment D, page 2, lines 64 through 76. The true-up of the true-
up rate is calculated on Attachment B, page 1 (Company Case) or page 2 (Staff Case), line 24, to
be 0.0838 t/kWh. The Staff and Company calculate the same rate for the true-up of the true-up.
STAFF COMMENTS 9 MAY 18,2010
PCARATES
The Staff s calculated PCA rate of 0.3114 t/k Wh is the sum of the three components
described above (0.1404 + 0.0872 + 0.0838 = 0.3114). This rate is shown on Attachment B,
page 2, line 27. This rate is well below the 1.4022 t/k Wh currently in place. This PCA rate
decrease is not a refud of below normal power costs but simply a lower surcharge than the
surcharge currently in place. Attachment E, page 1, shows the impact on all Idaho Power customer
classes of the PCA rate decrease.
Base Rates
A. Bridger eoal eosts
The Settlement Stipulation accepted by the Commission in Case No. IPC-E-09-30, Order
No. 30978, provided for an increase in base rates ifPCA rates were reduced in this fiing. The
magnitude of the base rate increase includes, as a component, normal power supply costs. Normal
power supply costs were identified in Case No. IPC-E-IO-01, Order No. 31042, as approximately
$63.7 millon more than are included in present base rates. The one unresolved issue from that
case that could affect this amount was the cost of Bridger coaL. The Bridger coal cost issue was
cared over to this case to obtain a timely decision in the cited case and to allow other pertinent
information to be made available. That information is now available.
The Bridger coal cost issue has come up because the coal supply contract with Bridger
Coal Company recently expired and coal costs under the new contract are significantly higher than
they were under the old contract. Also, Bridger Coal Company is a wholly-owned subsidiar of
Idaho Power Company and PacifiCorp who own the Jim Bridger power plant. The concern is
whether customers are getting the coal prices they should given the fact that the contract is with an
affiiate. When a regulated utilty contracts with an unregulated affliate, it is common practice to
reflect in rates the lower of the actual cost or the comparable market cost. The issue was first
raised in Oregon PUC Docket No. UE 214 where direct and rebuttal testimony have been filed and
discovery requests have been asked and answered. That case continues and will be decided later in
the year.
The IPUC Staff has reviewed the new contract, testimony and production requests in the
Oregon case, a white paper prepared by Idaho Power Company to address the issues (including the
lower of cost or market issue), responses to production requests asked by Idaho Staff and
Intervenors and Idaho Power witness Tom Harey's testimony in this case. The Staff concludes
that Idaho Power's positions with regard to Bridger coal costs appear logical, reasonable and
STAFF COMMENTS 10 MAY 18,2010
consistent. In addition, Bridger Coal Company profits flow to Idaho Power subsidiar IERCO and
IERCO profits flow back to customers in Idaho Power Company general rate cases. Staff has not
identified any justification to reject or modify the Bridger coal costs proposed by the Company and
included in base power supply costs in this fiing. Therefore, Staff continues to support additional
normalized base power supply costs of$63.7 millon.
B. Rates
The Company and Staff are both proposing a substantial decrease in PCA rates of
approximately $147 milion. Under the Stipulation a PCA reduction of this magnitude allows the
Company to move $63.7 milion (Case No. IPC-E-IO-01, Order No. 31042) in increased normal
power supply costs into base rates along with $25 milion in other costs. The Stipulation fuher
requires that the Base Rate increase be spread to customer classes and rate components within each
customer class on an equal percentage of revenue basis, except for Residential and Small
Commercial customer charges, which are to remain unchanged. Company witness Tatum
provided the calculation of the new base rates in Exhibit No.2, pages 2 through 25. Staffhas
reviewed these calculations and agrees that they are correct. Staff Attachment E, page 2, shows
the average increase in base rates by customer class.
Combined PCA and Base Rates
Attachment E, page 3 shows the combined impact by customer class of Staff-proposed
changes in PCA and base rates. The impact is measured against all biled revenue, not just base
rates. Again, the percentage changes var widely. The decrease is $58.2 milion, which averages
6.49% across all customer classes. The Schedule 1 Residential class decrease is 3.24%.
Other PCA Attachments
The Staff has included three other Attachments that provide summary or historical
information concerning the PCA. Staff Attachment F summarizes PCA expense amounts and rate
components for this case. Page 1 shows the Company's case and page 2 shows the Staffs case.
The Attachments also show amounts allocated to other jurisdictions and amounts shared with
shareholders. Attachment G is a bar graph that shows the amount of each PCA since its inception
including the Company and Staff Proposals in this case. Attachment H graphically shows base
rates and PCA rates for the Residential Customer Class from 1994 to the present time. It also
shows the impact of the Company and Staffbase rate and PCA rate proposals in this case.
STAFF COMMENTS 11 MAY 18,2010
CONSUMER ISSUES
Idaho Power's PCA Application, fied on April 15, 2010, contained both the customer
notice and press release. Staff reviewed the notice and press release and determined that they
complied with the requirements of Rule 125, IPUC Rules of Procedure, IDAPA 31.01.01. The
customer notice was mailed with Idaho Power's cyclical bilings beginning April 23, 2010 and
ending May 24, 2010. Customers had until May 18, 2010 to file comments. In addition to
describing the current filing, the customer notice also mentions proposed rate increases associated
with the recovery of Advanced Metering Infrastructure investment (Case No. IPC-E-I0-06), the
anual Fixed Cost Adjustment (Case No. IPC-E-I0-07), and the recovery of Defined Benefit
Pension Expense (Case No. IPC-E-I0-08). The customer notice recognizes that the Company
proposed 6.5% overall rate decrease in this case (lPC-E-IO-12) wil be offset by any increase
granted by the Commission in the other three cases. The notice states, "If the three proposals are
approved along with the proposed PCA reduction, customers wil experience a $46.6 milion
overall rate reduction, or an average of 5.2%."
As of May 17, 2010, two customers had submitted comments to the Commission regarding
the PCA. One customer is in favor of the proposed reduction in the PCA charge, though the
customer feels that the reduction should be larger. The other customer questions why the proposed
PCA reduction is less for residential customers than the overall proposed decrease. The customer
also feels that residential customers are subsidizing other classes of customers, all electric
residential customers are being unfairly penalized, and it is wrong to use rate schedules to force
energy conservation.
STAFF RECOMMENDATION
The Staff recommends that the Commission approve the base rate increases fied by the
Company and reviewed by Staff. The increase has been filed in conformance with Order No.
30978 issued in Case No. IPC-E-09-30.
The Staff fuher recommends that the Commission approve a PCA rate of
0.3114 t/kWh for the June 1,2010 through May 31, 2011 period. This PCA rate differs from the
Company's proposal due to the true-up interest adjustment recommended by Staff in these
comments. The Staff recommends that base rate changes and PCA rate changes be effective
June 1,2010.
