Report Organization
Idaho Public Utilities Commission Order No. 29209 and Order No. 29416 in Case No. PAC-E-03-14 requires Rocky
Mountain Power (the Company), a division of PacifiCorp, prepare an annual report on the Idaho lnigation Load
Control Program (Program). As approved by the Commission in Order No. 30243, Rocky Mountain Power initiated a
dispatch able irrigation pilot program (Schedule 72A) evaluating the effcacy of a 2-way control technology unique to
the irrigation industry. In addition to the standard analysis on Schedule 72, this report wil include a review of
Schedule 72A as required by the Commission order. The Schedule 72A assessment wil follow the standard report.
Finally, summary statistics from both Schedule 72 and Schedule 72A will be combined and presented.
Background
Subsequent to 2003, reporting requirements include responses to the following:
1. The number of irrigation customers who were eligible to participate in the Program
2. The number of irrigation customers who entered into a load control Service Agreement
3. The number of irrigation customers who participated in the Program for the full three and one-half months
4. The number of irrigation customers who are not eligible to participate in the following year's Program
5. The total dollar amount of credits provided under the Program identified by month
6. Proposed changes and/or recommendations to improve the Program
2007 Schedule 72 (Scheduled Forward) Results
Table One detail§ eligible 2007 Schedule 10 sites and customers (requirement #1)1. Table One also contains counts
of customers and sites that entered into an actual load control contract (requirement #2). Details for Program years
2003, 2004, 2005 and 2006 are provided for companson. The data presented in Table One reflect the number of
irrigation customers and sites that participated in the Program for the full three and one-half months (requirement
#3). In 2007, 14.8% of total available sites and 20.0% of the total available customers participated in the Program.
There are zero customers NOT eligible to participate in 2007 (requirement #4).
1 Data are reportd as of 30 September 2007. This notation is importnt as Program partcipants may change throughout the season as a function of
agri-business, weather, crop type andlor equipment vagaries. Wherever poible and based on what the Irrgation Management Team has
determined to be the most understandable way to communicate quantitative Program demographics and impact, reportng date may change.
Accrdingly, and throughout this report the date for the specifc quantitatie reult wil be noted.

The monthly participation credit amounts issued to 2007 Program participants are presented in Table Two
(requirement #5). Total Program participation credits ($684,201.09) represent a 26.1 % decrease (or -$240,652.35)
over 2006 credits. This decrease in credits occurred despite the addition of $450,000 (denoted 'Supplemental
Credit') divided among all 2007 Program participants. The reason for this decrease is because a significant count of
growers elected to participate in the Dispatchable (Schedule 72A) pilot program. Table Two further presents the total
amount of resource under contract at the time of credit issuance. Table Three presents a comparative analysis of
credits issued for the 2003, 2004, 2005, 2006 and 2007 Program years.
Further, it should be noted that the 2007 Program year-end report statistics are based on the Program's
transactional database. The database offers a snapshot in time and does not take into consideration Program
participants who may have elected to discontinue partcipation prior to 15 September.

Table Four provides information on 2007 Program costs (Note: Program costs for both Schedule Forward and
Dispatchable initiatives are included in Table Four. Separate program costs used in determining cost-effectiveness
are delineated in each of the 'Cost-effectiveness' sections of the report.). For years 2003, 2004, 2005 and 2006
Program costs are represented for comparative purposes.
During 2007 100% of sites that participated in the Scheduled Forward Program during 2006 were visited to inspect
equipment and identify faulty timers3. This practice of visiting ALL participating sites was initiated in 2006 in
response to the lack of control equipment reliabilty. This site inspection practice had a dramatic effect on customer
service as there was less than eight customer service calls (or 1.17% of total timer-installed sites)4 associated with
equipment failures during 2007. For 2007 the more than doubling of costs for field expenses is due to (1) the $529k
for new 2-way equipment and (2) field labor costs to remove timer units in advance of the installation of 2-way
equipment and required for inventory balancing.

Table Five provides avoided kW statistics and participation site counts for the Scheduled Forward initiative based on
participation option. A couple of observations are noteworty. First, and as reported in the 2006 year-end report, the
three hour option was not a particularly popular offer. Growers reported that the inconvenience and associated labor
of having to accmmodate a three-hour interruption was not offset by the participation credit. Second, the six hour
dispatch blocks were, by far, the most popular option, representing 88.1 % of total Program site participation and
87.1% of total avoided kW.

Cost.effectiveness analyses
Cost-effectiveness will be calculated for the following program components:
1. Schedule 72 (Scheduled Forward) only
2. Schedule 72A (Dispatchable) only
3. Schedule 72 and Schedule 72A (combined)
Results on each of the four standard utility industry tests-(1) Total Resource Cost (TRC); (2) Utilty; (3)
Ratepayer and (4) Participant will be provided for each of the three aforementioned program cases. The tests
for Schedule 72 (Scheduled Forward program component) wil be based upon the cost and avoided MW
values as defined in Table Ten below5. The information below wil descnbe the methodology and wil be used
in evaluating each of the subsequent program components.

Total
The Program cost-effectiveness analysis is based on the ratio of the present value of the Program's benefits
to costs and the net benefits (benefits minus costs), discounted at the appropriate rate for the various
benefit/cost tests6. The benefits are based on the calculations as defined by the Company's Commercial &
Trading organization7. Costs used in these calculations include administrative costs, contractor costs (field
technician and database design / administration), participant credits, and associated equipment costs. The
participation credits are not included in the Total Resource Cost (TRC) test because they are a transfer
payment from the utilty to the participants.
The cost-effectiveness of the Program was calculated by Quantec using a simplified spreadsheet analysis.
This analysis multiplies average demand reductions for the June, July and August period (as is consistent
with previous program year calculations) as a result of customers participating in the Program by the
estimated value of avoided demand noted above. Again, this value is $49.56/kW-yr. This value is increased
by 10% to account for the effect of line (T&D) losses, resulting in a value of $54.52/kW-yr used in the cost-

Based on previous research that showed energy use is 'shifted' rather than 'avoided', lost revenues are not
included as a cost and energy savings are not applicable as indicated above.
As shown in Table Eleven, the Scheduled Forward component of the program passes the TRC Test. The
Scheduled Forward program also passes the Utility and Ratepayer Test. Since the participant incurs no costs
the benefit/cost ratio would be infinite for the Participant Test. Accordingly, for the Participant Test the value

Measurement & Verification (M&Y) processes
Consistent with the previous four irrigation seasons, field technicians prepared random, unannounæd site
visits for the purpose of ensuring the integrity of timer performanæ and the absence of grower fraud. Five
timer and timer-related parameters-(1) tape seal, (2) meter lock, (3) battery, (4) clock calendar and (5) pump
panel-were considered in the evaluation. M&V technicians were also asked to confirm the presenæ of a
PacifiCorp Site ID sticker for inventory purposes. Where it is suspected there were vanances in anyone or
multiple of the aforementioned evaluation elements field technicians were required to indicate said variances
in the database and to the Irrigation Load Control Management Team for adjudication.
The results of the 2007 M&V activities are indicated in Table Twelve. There were two sites reported to the
Irrigation Load Control Management Team for adjudication. On both of these occasions the Irngation Product
Manager contacted the growers involved. With each incident the information clearly indicated no outward
attempt to circumvent the control equipment or defraud Rocky Mountain Power. In both instances the ænter
pivot was stopped during a control event at a position in the field requiring the grower to manually by-pass
the equipment in order to move the pivot for the harvesting machinery too access that position in the field.
Subsequently, the control equipment was corrected for proper dispatch sequencing. In both instanæs
growers were advised that in future they should contact Rocky Mountain Power prior to manipulating the
control equipment.

2007 Schedule 72A (Dispatch able) Results
In the fall of 2006, coincident with the year-end report and based on the results of a 25-unit pilot test of the prototype
control technology, Rocky Mountain Power proposed and subsequently received permission to pursue a full-scale
pilot test of a fuy dispatchable solution for the 2007 irrigation season. The results of the Dispatchable program are
described below.
Background
A total of 17 customers (448 sites) participated in the full-scale Dispatchable initiative using the propnetary
(cellular / RF) M2M pump / pivot control technology. M2M provides the underlying remote control equipment
to Valley lnigation the world's largest agricultural pivot manufacturer. This particular product line (remote
pivot control) has been available for five years. Rocky Mountain Power worked with M2M in the design,
development and manufacturing of a wireless proprietary master / slave configuration such that a 1 to many
pump / pivot configuration could provide independent control of irrigation sites8. This was viewed as a major
step forward in providing an agn-business solution that would attract grower participation.
Prospective large-grower participants were contacted and onginally notified of the pilot in late fall 2006. In the
spring of 2007 these growers were again notified that the pilot had been approved by the Idaho Public
Utilties Commission and asked if they would like to participate. Growers who indicated a preference for
participation dunng the 2007 season were subsequently notified to disregard the standard notification mailng
announcing the Idaho Irrigation Load Control program for 2007. Growers were also told that the Irrigation
Management Team would work directly with them or their farm managers in preparing program participation
application materials, site preparation / installation and training on equipment use.
Concurrent with the management of the grower interface, the Irrigation Management Team worked closely
with M2M Communication in technology reviews and softare development readying the technology for
manufactunng and later field deployments.
The Irrigation Management Team also deployed field technicians to begin removal of the solid-state timers
during the late winter and early spring period prepanng the Dispatchable sites to receive the new 2-way
control units. These parallel efforts (technology development, grower communications and site preparation)
continued during the late winter / early spnng period until M2M units began to ship.
In communicating with the growers about the Dispatchable program growers were apprised of the
foundational components of the Dispatchable pilot including but not limited to the operating parameters
described in the 'Tariff highlights' below.
B As with the timer technology it should be noted that a single irrgation sit oftn required multple 'slave' units in order to serviæ a single site. That
is, it is not uncommon for a single pump to be sized and connected to multiple pivots. The master/slave technology provided by M2M allows the user
to independently operate the pump as well as each pivot site. With these configurations, however, separate field installations had to be completed on
the pump as well as on each pivot.
2007 Idaho Irrgation Load Control Program-Final Report Page 10 of41
Tariff highlights
The operational parameters of the approved tariff are bulleted below:
. Applicable: To qualifying customers served on Schedule 10 and who met the following participation
criteria:
o an aggregate minimum of 1 MW (1,500 Hp) demand under their control (single account or
multiple accounts) for either or both of July or August
o an integrated pump / pivot irngation system
o a minimum pump size of 100 Hp
o continuous access to the Intemet from May 1 through September 15
. Grower Notification: grower would be notified on a day-pnor and day-of the Dispatch Event
. Grower Opt-out: growers could, upon their discretion, opt-out of 2 'Dispatch Events' with no
financial penalty. Growers could also opt~out of 3 additional 'Dispatch Events' but would incur a
financial penalty described below in the 'Liquidated Damages' section.
. Liquidated Damages: Growers could 'opt-out' of up to a maximum of five Dispatch Events with the
provision that any opt-outs beyond the first two the grower would have their credits reduced by the
amount the Company would otherwise have to pay for power for the duration of the 'Dispatch
Event'.
. Dispatch Conditions: The Company shall have the right to implement a Dispatch Event for
participating customers accrding to the following criteria:
o Available Dispatch Hours: 2:00 PM to 8:00 PM Mountain Daylight Savings Time (MDT)
o Maximum Dispatch Hours: 65 hours per Irrigation Season
o Dispatch Duration: Not more than three and one-half hours per Dispatch Event
o Dispatch Event Frequency: limited to a single (1) Dispatch Event per day
o Dispatch Days: Monday through Friday (inclusive)
o Dispatch Day Exclusions: July 4 and July 24 and/or their respective designated weekday
offcial holiday
Installation schedule
The design, manufacturing, and installation nuances related to the dispatch able units and the requirement to
ensure 100% quality control of all hardware components meant installation was delayed such that not all
units were fully installed by the start of the tariffed irngation season (1 June). Nevertheless, a substantial
number of units (271 units OR 41.6MW) were installed and readied prior to the initial Dispatch Event on 6
July. Subsequent installations and training of growers on equipment use meant that installations came on-
line in series following installation, database and Internet control reading of all user interfaces and user
training.
To manage this process and because there were a far greater number of installation considerations that
needed to be taken into account, the Irrigation Management Team contacted a single grower who expressed
interest in the technology and was wiling to act as defacto 'guinea pigs' for technology introduction. This
gesture on the part of this grower allowed the Irrigation Management Team to work through the many
2007 Idaho Irrgation Load Contrl Program-Final Report Page 11 of41
technical and operational challenges the new technology presented. This meant that, instead of installng all
448 participating sites in parallel with multiple installation teams, the field effort would focus on getting the
installation process, technology settings and database components correct with this single grower before
moving on to parallel installations with subsequent growers.
In the end, this approach proved effective for two reasons. First, problems and technical challenges could be
reasonably solved without unduly impacting all growers. The potential 'damage' (negative spin, grower
discontent, and frustrations) was limited to a single grower rather than to the entire population of participating
growers. Second, field costs were limited as field re-work was constrained to a specific count of sites and not
all of the participating sites. This approach resulted in conserving field expenses. The following example may
help to further clarify the field cost issue.
When field installations were begun, units were deployed with Operating System (OS) v 3.0. By the time the
installation of all units was complete OS v 9.0 was being installed. Having to re-install all 448 sites (and, in
many cases, their 'slave' counterparts) with each new release of the OS (seven additional site visits to each
site) would have unduly impacted field operating budgets and further delayed installation of units to all
growers. As it turned out, the Irngation Management Team was able to eliminate a certain amount of
redundant field work and contain grower discontent by adopting a serial approach to installation rather than a
parallel approach. The trade-off, of course, was that participating loads came on-line in chunks throughout
July (see Table Thirteen) with all participating loads available for the August through September dispatch
period.

Customer Credits
All dispatch customers were issued both standard tariff credits of $11.19/kW avoided and supplemental
credits. Supplemental credits were calculated based upon the porton of load a grower's particular pump site
represented of the total (both Scheduled Forward and Dispatchable) under control for the 2007 irrigation
season. Credits by type and total credits are reflected in Table Fifteen below.
Table Fifteen

Credit Type
Standard Supplemental
Credit Amount $806,293.21 $261,712.28
Total Dispatchable Credits $1 06800549
Customer Opt-Outs
Schedule 72A permits growers to 'opt-out' of two Dispatch Events with no financial penalty. Growers are also
permitted to opt out of three additional Dispatch Events but would be charged the price Rocky Mountain
Power would otherwise have to pay for power during that dispatch period. For the 2007 pilot season growers
were NOT assessed fees (credit discounts) for opt-outs beyond the allowed two. There were two reasons
growers were NOT assessed the fees.
2007 Idaho Irrgation Load Control Program-Final Report Page 13 of41
First, as an entirely new technology both softare and hardware needed to be stress-tested. In so doing the
Irrigation Management Team coordinated with the grower and their farm managers in executing and
requiring opt-outs during each of the 13 Dispatch Events in order to test both hardware and softare system
components.
Second, was the issue of technology usabilty and grower training. Technology usabilty was and remains the
single biggest obstacle to technology adoption. The Irngation Management Team understood that for the
Dispatchable initiative to be successful growers and their farm managers would have to change operational
habits and practices. Fundamentally, that meant controllng pump / pivot sites either through their cell phone
or the Internet. This was not a trivial consideration. Accrdingly, much effort was taken to train growers / farm
managers on the new technology.
The Irrigation Management Team urged practice use of the equipment, including opting-out of Dispatch
Events even though the grower would have otherwise participated in the Dispatch Event. The decision was
made and the objective adopted to get growers / farm managers comfortable with the technology and its
operation. Bottom line: Schedule 72A was a pilot and the Irngation Management Team treated it as such and
encouraged growers / farm managers to do likewise. Nevertheless, statistics were gathered on the count of
opt-outs and load NOT avoided by Dispatch Event. These data are presented in Table Sixteen. (Note: of the
first three Dispatch Events (July 6, 12, 16) approximately 91 % of the opt-out counts onginated from a single
grower. Again, on July 26 and 31 more than 80% of the opt-outs originated from that same grower.)

2007 Dispatch Events
The avoided demand by dispatch hour associated with each of the Dispatch Events is presented in Table
Seventeen. The values in this table represent dispatchable loads only. A zero (0) appears in several of the
hourly ælls (most notably the 2:00p-4:00p block). This is due to the fact that the dispatchable initiative was
only exercised for either a 3.0 or 3.5 hour block (4:00p-7:00p / 7:30p). The reader should also be aware that
on July 6 and, again, on July 16 the Dispatchable option was exercised for 3.5 hours. To accommodate the
Y2 hour during the 7:00p-7:59p period the Dispatchable load was reduæd by 50%. In reality the full load was
realized for the first 30-minutes of this dispatch hour and zero load during the secnd half of the 7:00p-7:59p
period. While not perfect, taking 50% of the total load was the most expeditious way to represent these data
in Table Seventeen without using Y2 hour increment categories. Table Seventeen averages the loads
(weighing each 'Dispatch Event' equally) by hour for each of the 13 'Dispatch Events'. Finally, it should be
noted that there were NO (zero) instances reported where, onæ the technology was installed tested and
operational on a stable operating system, the technology failed to respond to a Dispatch Event.

Customer Feedback
The Company has, based on historical precedence, meteorological considerations and other class 1
initiatives, determined there would likely be 40 hours or 0.5% of the available annual hours a class 1
resource (such as irrigation load control) would likely operate11. The Irrigation Management Team wanted to
provide growers with a realistic feel for the number and duration of dispatches so they could provide
reasonable post-season feedback and could make a realistic assessment for participation in subsequent
irrigation seasons. The Irrigation Management Team was also interested in this feedback so the appropnate
adjustments, if any, could be made to improve the program offering.
As a pilot, and in addition to the ad hoc feedback received from growers / farm managers throughout the
irrigation load control season, it was important to collect grower data relative to the Dispatchable initiative.
Moreover, gathering grower feedback was required in the Commission order approving Schedule 72A. It was
hoped that information gained from the questionnaire and associated discussion would assist in making
specific changes that would (1) improve operations, (2) enhance the value proposition to both the grower and
to Rocky Mountain Power, and (3) improve cost-effectiveness. Accordingly, a brief questionnaire (see
Attachment One) was developed and used in a post-season interview with growers. In addition to the
questionnaire a follow-up information gathering interview was held with each of the growers / farm managers
to gain additional insights / observations as to the Dispatchable initiative's strengths and weaknesses. The
six broad categones investigated by the questionnaire and reviewed in discussion are listed below.
1. Program introduction / terms and conditions
2. Selecting and scheduling site installations
3. Field installation activities / processes
4. 'Dispatch Event' operations
5. Training
6. M2M control equipment
Results from the questionnaire / interview with growers sort themselves into nine categories. A succinct
descnption along with representative grower comments related to each of the categones follows.
1. The Company did a relatively good job informally communicating with growers as to the value
proposition, tariff parameters and technology operations. Growers partcularly appreciated the local
presence of well known field technicians in whom they had confidence and trust to accurately and
correctly represent the technology and operational considerations. The Company's local, well-
known and trusted Customer and Community Management Representative (Bob Smead) was also
cited by growers as having made program components understandable.
2. Growers were not as complementary when it came to keeping them (growers) abreast of
development efforts. Until technical issues were largely resolved, the Irrigation Management Team
allowed attentions to focus nearly exclusively on problem solving and gave little consideration to
growers waiting in the wings for implementation on their farm(s). Communications to the large
grower population was lacking.
11 The 40-hours of dispatch is consistent wiUi what oUier electc utilities report I anticipate based on requirements for peak avoidance.
2007 Idaho Irrgation Load Control Program-Final Report Page 16 of41
3. While training effort were ranked positively, nearly all growers offered a number of
recommendations to improve training / technology implementation. Grower criticisms were
instructive in assisting the Irrigation Management Team in making adjustments to the irrigation
initiative. The nature of the criticisms (some of which are indicated below) suggest a partnership
approach between growers and the Company.

works.. . also need better / more explanation as to why certain sites are not
applicable for participation.
Need to do a better job of visiting with growers prior to the install and
explaining operations and issues and how they impact the system.
The information for managing slave / masters could and should be made more
clear.
On the website it would be helpful to be able to use the back key...a/so the
website times-out too quickly need to lengthen this capability.
The website need to be explained better or made to be more intuitive so it can
stand alone without so much training / rehearsal.
Naming conventions don't work for when you are just managing pumps vs.
pumps and pivots...not being able to independently manage these units and
name ilem axoromwy ma~s ile ~stem awkwam
Training, particularly for when you're training just for surface water folks, need
improvement.
We wil need training again next year to know what we need to do and how to
operate the equipment.
Perhaps we ought to do both group training and individual (1: 1) training, that
way we can cover general stuff and take advantage of general information and
then provide specifics.
4. Growers were somewhat irritated as to the delay in program implementation. These delays were
viewed as being organizational and not technology-driven. There was a universally simple and
clear message:
Make sure the Company does enough in advance so that there is suffcient
time to implement the program
5. The 'opt-out' option was enormously important to the Dispatchable value proposition. Without this
option growers would have simply elected to not participate in the initiative.
The 'opt-out' stuf was important to making the program work.. .single most
important piece.
Flexibilit (opt-out) is what makes the whole deal work. Without this option this
program is dead.
Options (opt-outs) are key!
More options is good...
Opt-outs are the key.
Key is to have opt-outs...that is what makes the program work.
6. The accptance of the M2M control unit would take time for farm managers to get their arms
around and get comfortable with. This finding was corroborated with data from Valmont Industries
(Valley Irrigation) who indicated that it typically takes growers 3 seasons or more to become
2007 Idaho Irrgation Load Control Program-Final Report Page 17 of 41
completely familar with the technology and confident it its reliabilty. Nevertheless growers feel it is
a worthwhile transition and investment in time.
The farm managers learned how to use equipment but wil have to re-Ieam
next year.
We stil have a way to go before all farm managers feel comfortable (probably
3-years for some of the farm managers) with the new equipment. But we wil
get there and in the end it wil help the power company and help us with
credits.
7. Growers valued and appreciated being able to solve problems with local resources. In the end,
managing irrigation pumps / chemical pump tanks and pivots via the existing control panels and
bolt-on utility equipment requires highly specialized knowledge. Growers do not allow anybody to
drive onto their propert and work on equipment which can often impact ::$300,000 in potential
revenue on a single pivot. Moreover, there are real threats of biological infestations that can be
introduced to the acreage if vehicles and equipment are not properly cared for, attended to or if
those doing the work do not have knowledge of agri-business operations.
When you just throw program at us and sçiy 'OK there it is' than it don't
work.. .the people you have working on it (load control program) makes the
whole deal work. If Brad, Andrew or Ty would have ignored the problems then
we would have had a different result.
Yeah, there were some glitches...but want local resources...don't want
somebody in Chicago answering the phone or tellng us what to do without
really meaning it.. . this actually worked and your local people made it
work.. .didn't hurt yield or quality either.
The inigation team got it working...you guys worked to get the farm managers
to make it work.
8. Growers made a number of recommendations to improve control technology operations and
program viability. It should be important to note that virtually 100% of the changes are softare
initiated adjustments and not changes to the fundamental underlying hardware. Among other items
growers recommended the following:
.:. Use text messaging for communicating status change conditions... the robotic voice is
diffcult to understand. Also, provide text messaging in Spanish.
.:. Further shorten the call sequence to execute a particular command. Provide a sequence of
code numbers without having to listen to the voice prompts... put this on the 'cheat sheets'
provided to the growers.
.:. Provide the user with the capabilty to view units grouped as well as ungrouped for the
offce staff.
.:. Provide exception reporting and not simply status change reportng.
.:. Want feedback when you opt-out. Growers need a little bit more of a road map such as
pop-up screen saying "you are opting out, please confirm".
.:. The status summary screen is not entirely clear on what is going on in the field.
9. Operating parameters appear to be an accptable risk. That is, the three hour dispatch event was
seen as virtually no different as a potential four hour Dispatch Event. Moreover, it was reported that
a total of 50 hours seemed workable to growers so long as it got past the period when the canopy
had grown over.

Cost-effectiveness analyses
Cost-effectiveness calculations were prepared for each of the four standard utility industry tests in the
manner consistent with that described above for the Schedule 72 portion of this program. Benefits and costs
for Schedule 72A (Dispatchable option) upon which calculations are prepared are presented in Table

2007 Idaho Irrgaton Load Contrl Proram-Final Report Page 19 of41
2007 Schedule 72 & Schedule 72A Results
This section of the report provides a brief quantitative summary of the two combined initiatives-Schedule 72
(Scheduled Forward) and Schedule 72A (Dispatchable). Only minimum narrative wil be provided as the majority of
the rationale behind these data has already been provided.
Avoided demand
The avoided demand by dispatch hour associated with each of the Dispatch Events is presented in Table
Twenty. The values in this table are additive. That is, they represent the combination of Scheduled Forward
loads plus Dispatchable loads. Two important facts need to be taken into consideration in evaluating these
data. First, a zero (0) appears in several cells. This is due to the fact that the Scheduled Forward initiative
operates Monday thru Thursday inclusive. When the Dispatchable initiative was exercised on Fnday the only
avoided demand is that associated with Dispatchable loads. Second, on July 6th and, again, on July 16th the
Dispatchable option was exercised for 3.5 hours. To accommodate the Y2 hour during the 7:00p-7:59p penod
the Dispatchable load was reduced by 50%. In reality the full load was realized for the first 30-minutes of this
dispatch hour and zero load during the second half of the 7:00p-7:59p period. While not perfect, taking 50%
of the total load was the most expeditious way to represent these data. Finally, the table calculates the
average (mean) as well as a median for each of the hourly loads per 'Dispatch Event'.

2007 Idaho Irrgation Load Control Proram-Final Report Page 20 of 41
Crop type analysis
Consistent with the 2006 report an analysis was prepared of avoided loads by crop type for the 2007 season. As
mentioned in the 2006 year-end report this analysis is somewhat problematic as a majonty offield installations
occur in January, February and March prior to when a grower has made a final decision on crops and prior to
planting. Nevertheless, field technicians either inquired of the grower as to crop type or could identify the
emerging crop himself (in the case of late-in-season installs). Table Twenty-One: 2007 Program Participation by
Crop Type / Application x Site Count & Average Avoided kW presents the results of these field data gathenng
efforts14. The avoided kW values were calculated by taking the full summer (1 June through 15 September)
average for each of the identified sites and summing those avoided kW values by crop type / application.

Table Twenty-Two: 2007 Program Participant Estimation of Crop Type x Total Acres presents field installer
estimates of 2007 Program participant crop types x acres16. Again, these are estimates are constrained by the
same parameters indicated in Table Twenty-One. In addition, data accuracy is further constrained by having to
estimate the size of the total acres under cultivation at a particular site. Accordingly, attempts to synch-up avoided
MW as reported in Table Twenty-One should be avoided.
14 Note: these estimates reprent infonnation about 2007 partcipating sites in the PacifCorp service terrtory. Specifcally these data repreent sites
where the crop type has been indicated by field installation teams. Sites where crop type has not been identified by field installation teams are
eliminated as part of the query.
15 Data includes results from both Scheduled Forward as well as Dispatchable initiatives
16 The query extcting these data reuire that both 'crop type' and 'acreage' fields be populated with values from field installation teams. Where
either or both fields were left blank the values were not included in the resultant table.

Load profile data (CB-67 (Big Grassey))
Throughout the control period, Company SCADA data were collected and used in preparing impact analyses.
Transmission Circuit Breaker #67 (CB-67 (Big Grassey)) aggregates four distribution substations (Hamer, Sandune,
Camas and Dubois) which were known to have a significant number of Program participants. A significant portion of
the participants in this area, however, partcipated in the Dispatchable (Schedule 72A) program. Hence the impact of
the Scheduled Forward component is diffcult to observe. Nevertheless, SCADA values were taken and logged at
20-second intervals for periods when dispatches were executed. Virtually all of the 13 'Dispatch Events' had
identical profiles. Two of those profiles are described and presented in the ilustrations below.
Ilustration One (Big Grassey Transmission Load Profile July 12, 2007 (CB 67-'Big Grassey')) depicts gnd impacts as
a function of both Scheduled Forward (Schedule 72) and Dispatchable (Schedule 72A) options. What is noteworthy
is (1) the magnitude of the load shifting effect as depicted in the difference between control and non-control hours
and (2) the impact of 'load shaping' as a function of the combined impacts of the Scheduled Forward and
Dispatchable program components. This shaping capabilty is important as it provides Rocky Mountain Power with
greater optionality and control over the grid in systematically meeting load requirements during summer peak
periods.
The 'shaping' is dramatically different than that experienced with the use of the electronic timers alone. The
aggregate impact of electronic timers results in a hard edge in the SCADA profile as opposed to a more gradual load
shape with the combined used of the electronic timers and the 2-way control equipment. For comparison and
ilustrative purposes of this 'edging effect' 2006 load data is provided in Ilustration Two.

non-dispatch days (including scheduled forward dispatches).
Additional Southeast Idaho Service Territory average hourly interval load data plots wil be provided below. In
evaluating these data a cautionary note is warranted in their interpretation. The aggregate Southeast Idaho load
profile data provides some indication as to impacts as a function of the Irngation Load Control program. These
data, however, should not be interpreted as being conclusive evidence for or against operational effcacy as there
are a wide variety of activities impacting the electric gndother than irrigation alone. Where appropriate, attempts
wil be made to provide interpretation / rationale of the data that is presented. Also, and at the time of the

Ilustration Five (Total PacifiCorp Hourly Idaho Loads (June+July): Schedule 72 Idaho Irrigation Load Control-
Scheduled Forward Days vs. Non-Control Days) plots the total Southeast Idaho Service Territory average hourly
interval load data for June and July. Data is segregated by the Scheduled Forward dispatch days (Monday thru
Thursday inclusive) and non-dispatch days (Friday thru Sunday inclusive)18.
Two important findings are revealed in these data. First, Friday and weekend loads are approximately 75MW less
than Monday thru Thursday loads. This is not surprising but it does confirm what is typical for the Rocky Mountain
Power system. Second, there is an approximate 25MW 'depression' on weekday afternoons during the control
penod. This highly unusual pattern is unique to agricultural loads as residential and commercial loads are
'temperature-following' and would otherwise be expected to rise during the heat in the afternoon. This unique
agricultural-pattern is likely the result of two culprits: (a) the six-hour Scheduled Forward dispatch block and (b)
grower tendency to minimize water loss to evapotranspiration during the heat of summer afternoons by reducing,
where possible, irrigation turns dunng those hours.
18 There were zero days in June where the Dispatchable reouræ was executed. Ergo, only Scheduled Foiward Dispatch Events are reported for
this particular plot.

Ilustration Six (Total PacifiCorp Hourly Idaho Loads Comparing Schedule 72 + Schedule 72A to Non-Control

July. Data is segregated by the Scheduled Forward dispatch days (Monday thru Thursday inclusive) +
Dispatchable dispatch days vs. non-dispatch days (Friday thru Sunday inclusive + 6 July which was a
Dispatchable day and which fell on Friday). The results of these plots are somewhat confusing as we would have
anticipated an additive drop in load when compared to the non-control days. It is likely that the less-than-
remarkable difference is due to the fact that non-control days are only marginally higher than the control periods
as a function of the naturally occurring reduction in Friday and weekend loads. Again, it is, at best, diffcult to draw
conclusions on these data taking into consideration gnd vagaries, agricultural practices, meteorological
considerations and on-going program operations when the entire Southeast Idaho load is considered.

results of these plots are interesting in that they indicate the effcacy of the dispatch able component to shift loads
to shoulder and off-peak hours.
Final note on SCADA plots: taking the previous six ilustrations into consideration the impact of irrigation load
control is diffcult to deny. By the same token, using SCADA data it is diffcult, at best, to precisely determine the
magnitude of its impact. At this point what can be provided is nominal data on what occurred.

Cost-effectiveness analyses
Cost-effectiveness calculations were prepared for each of the four standard utility industry tests in a manner
consistent with the methodologies described earlier. In this evaluation, however, full program costs for both
Schedule 72 and Schedule 72A together with benefits from both program components are used as the basis for the
evaluations. Benefits and Costs for Schedule 72A upon which calculations are prepared are presented in Table
Twenty-Three below19.

As shown in Table Twenty-Four, the combined initiatives (Schedule 72 + Schedule 72A) pass the TRC, Utilty and
Ratepayer Tests. The Program also passes the Participant Test. However, since the participant incurs no costs the
benefit/cost ratio would be infinite. AccordinglyJor the Participant Test the value is indicated as 'N/A' in the
Benefit/Cost Ratio column.

Conclusions & Recommendations
The pilot Dispatchable initiative was positively received by the growers and significantly oversubscribed for the 2007
irrigation season. There were four factors that can be attributed to the favorable reception:
1. The fundamental value proposition / program design that permits growers to opt-out of Dispatch Events.
Each and every one of the growers indicted that without the opt-out feature it is highly unlikely the pilot
would have been positively received and participation would have continued to hover in the range of
50MW. The abilty to opt-out is central to receiving favorable grower acceptance and making the
Dispatchable initiative work.
2007 Idaho Irrgation Load Control Program-Final Report Page 30 of41
2. Growers appear to have preliminarily concluded that high water use row crops (corn and potatoes) are not
adversely affected (either quality or yield impacts) by participation in the Dispatchable program. The
Irrigation Management Team wil continue to closely monitor grower perceptions relative to yield / quality
impacts as it relates to program participation.
3. Fewer dispatch hours. If either quality or yield were affected by the Dispatch Events growers simply would
not participate. As one grower indicated they can lose the entire participation credits in just a couple of
bushels per acre less yield. The current program design appears to be much better tailored to agri-
business needs and requirements and yet still provide grid benefits as measured by SCADA data.
4. Initiating and maintaining a local presence of agri-irngation / information systems specialists and irrigation
equipment specialists to ensure the initiative's success. Throughout the pilot, growers continued to
reassure Rocky Mountain Power of their commitment to stand behind the irrigation initiative as knotty
technical issues and operational considerations required attention. Both the growers and the Irrigation
Team understood that it would likely take three or more growing seasons until farm managers and growers
alike were fully inculcated with the remote control irngation management systems and equipment.
Providing skiled, local and professional resources on a 7 x 24 basis to train, council, instruct and / or
troubleshoot problems as they arose was viewed as important as the technology itself. Growers indicated
a favorable response to a joint (growers / Rocky Mountain Power) long-term partnership. Nearly all
growers point to this partnership and commitment to technològy innovation as an important underpinning
to program success.
Based on the results and findings from the 2007 Irngation Load Control initiative Rocky Mountain Power advances
the following four considerations as they relate to the 2008 effort and beyond.
1. The Dispatchable load control initiative should be a permanent offering in the portolio of grower
participation options. As part of the settlement reached with the Idaho Irrigation Pumpers Association in
the company's general rate case, Rocky Mountain Power wil modify the current tariff to reflect ongoing
Program operation and a revised level of incentive credits. The tariff wil include the appropnate
operational modifications gleaned from the 2007 pilot and agreed to as part of the stipulated settlement.
2. Due to (1) the difference in committed participation hours, (2) the inabilty to opt-out and (3) the availabilty
of advanced control technology it is likely that very few, if any, growers wil participate in the Scheduled
Forward initiative. Nevertheless, the choice to participate in this option should continue to be made
available to growers at least through the 2008 irrigation season. The intent would be to evaluate the
Scheduled Forward option at the conclusion of the 2008 season to determine its effcacy for subsequent
program years.
3. Allow growers to participate year-over-year without having to re-sign-up each year. Allowing growers to
participate without having to re-indicate their intent to participate would expedite operational
considerations and allow the Irngation Team to prepare for the ensuing irrigation season in a more
expeditious fashion. The current practice of having growers re-initiate their intent to participate in the
Irrigation Load Control Program is awkward and confusing to growers and adds an administrative burden
that could and should be removed to improve effciencies.
2007 Idaho Irrgation Load Contrl Program-Final Report Page 31 of41
4. Year-round operation. The magnitude (both scope and complexity) of the program requires practices and
procedures beyond the efforts that have driven program design, development and implementation thus far.
For instance, Rocky Mountain Power cannot reasonably expect to send notifications to growers by mid-
January; receive response back by mid-February and have units fully installed and operationally ready by
June 1. As noted above, Rocky Mountain Power received criticisms relative to timeliness of installs,
customer service and program operations. The criticism was largely 'self-inflicted' as the Irrigation
Management Team elected to expand the pilot beyond the onginal45 MW in an attempt to meet grower
desire for participation.
Implementing and managing over 100 MW employing a technology which requires a substantial change in
established irrigation practices has and wil, for at least the next three years, remain a year-round effort as
growers transition to new irrigation practices and habits. Moreover, using the advanced, remote 2-way
technology requires Rocky Mountain Power to maintain an on-going relationship with growers, farm
managers and ultimately participating pump / pivot sites throughout the irrigation season. Today,
operational practices are radically different than in previous program years under a Scheduled Forward
offering. For instance, initial and on-going training of the growers and of their farm managers in equipment
use and operation requires significant effort that must continue if program operations are expected to be
prudently implemented and robustly operated.
Near-term operation of the Irrigation Load Control Program wil entail more hours for management, and
additional outside resources for troubleshooting, training and customer service. Consequently, Rocky
Mountain Power expects a 3x or more increase in delivery expenses over the next several years.
Anticipated expense increases wil come from year-round staffng to meet work load requirements,
conversion of the pilot to a permanent program, grower training along with the management of a much
larger network. The Irngation Management Team wil, of course, continue to do everyhing possible to
retard program delivery costs.
While this transition wil be occurring over the next several years Rocky Mountain Power expects and is
fully prepared to judiciously maneuver through the often not-so-clear complex operational changes to meet
the challenges. Rocky Mountain Power also expects that changes may also be reflected in tariff
considerations. As tariff-related issues anse Rocky Mountain Power wil bring them forward to the
Commission for consideration.
