Rocky Mountain Power Idaho 2007 Anual Report
Executive summary
Rocky Mountain Power (the "Company") hereby provides its anual report of Idaho
demand-side management activities for Januar 1,2007 through December 31, 2007.
This report covers load management, energy efficiency and market transformation
activities fuded completely or in par by the Idaho Schedule 191. This reporting period
differs from the first report and was addressed in the first report. Summar level results
for the period are summarized below.
Table 1. Rocky Mountain Power - Idaho Summary Results
Total Revenue $2,048,020
Total Expenditures $2,120,643
Controllable loads - Megawatts 78
Energy savings - First year megawatt hours 8,092
Rocky Mountain Power's objectives in offering demand-side management programs to
their customers are: a) to acquire cost effective resources to help meet load growth and
system peak requirements, and b) to provide tools for customers and the state to lower
usage and demand in helping reduce their electricity costs. The 2007 energy efficiency
program set and collection rate remained the same as that initially implemented in 2006.
The irrigation load management program was enhanced with the piloting of a
dispatchable control option in 2007 to increase paricipation. This initial program set and
funding level was designed to meet the objectives in offering demand-side programs
while demonstrating utilty program delivery expertise and to assess the level at which
Idaho customers would paricipate.
In addition to managing the steadily increasing program paricipation in 2007, the
Company received the final report from Quantec, LLC that assessed potential for
capacity and energy based demand side resource opportities in all six states served by
PacifiCorp.
The Assessment of Long Term System- Wide Potential for Demand Side and other
Supplemental Resources (the "Potential Study") report received in June 2007 provided
additional information on the amounts, end uses and customer sectors that have the
highest potential or demand side and select supplemental resources.
The demand side resource acquisitions achieved by the curent set of Idaho programs in
2007 was generally consistent with the findings of the Potential Study by measure type
and sector, but did suggest more opportities might be available over a 20 year period

using preliminar cost effectiveness screens and third pary assumptions surrounding
paricipation.
Program performance on an individual program level and on an energy efficiency
portfolio basis was cost effective from all perspectives except the Rate Impact Test
(RIM) in 2007 as it was in the prior reporting period. The combination of increasing
demand for current program services and potential for increased resources as identified in
the potential assessment study supported the Company's recent decision to seek approval
to enhance existing programs, add a new program and request an increase in Schedule
191 collections in support of this increasing activity. This proceeding is currently pending
as Case No. PAC-E-08-01.
Demand-side Management Programs and Activity
Load management
This program is marketed as the Irrigation Load Control program and is offered to Idaho
irrigation customers receiving retail electric service on Schedule 10. Paricipants agree to
curail their electricity use during certain periods of time in exchange for participation
credits. Pursuant to Order No. 29209 and Order No. 29416 in Case No. P AC-E-03-14, a
report specific to this program for the 2007 season was submitted to the Commission on
December 19,2007. The December report covered the period from October 1,2006
through September 30, 2007. The report is dated December 20,2007 ("December
report") and information in Tables 2 and 12 of this anual report is taken from the
December irrigation program 2007 seasonal report.

included in the balancing account balance. Enrollment and site installations for the 2008
season are curently underway.
Residential Energy Efficiency
Home Energy Savings
The Home Energy Saving Program provides a broad framework to deliver incentives for
more efficient products and services to be installed or received by Idaho customers with a
new or existing home, multi-family unit or manufactured home. The program is delivered
through a third pary administrator hired by the Company. Schedule 118 and the program
web site at www.homeenergysavings.net/idaho/home are par of the program delivery
infrastructure. This web site is accessible through the Company web site at
ww.rockymtnpower.net/Article/Article45165.htmL. Schedule 118 does not curently
limit the fuding for this program.
Measures eligible for incentives include: washing machines, refrigerators, water heaters,
dishwashers, lighting (both compact florescent lamps (CFL)s and fixtures), cooling
equipment and services, insulation for ceiling and walls, windows and miscellaneous
equipment such as ceiling fans.
Incentives are provided to customers in two ways: (1) post-purchase delivery to the
customer for the majority of measures, and (2) through a manufacturer buy-down for
CFLs. A manufacturer buy-down results in lower retail prices for customers. While most
incentives are offered year round, the buy-down for CFLs in 2007 was offered seasonally
to complement other regional offerings.
This the second year of the program and as anticipated paricipation has been steadily
increasing. While not strictly comparable given different reporting periods, program
savings have approximately doubled since the last reporting period. Forty-six retailers
and contractors are actively paricipating. This represents an increase of five retailers or
contractors compared to the last reporting period.

In 2007, the Company and the program administrator teamed up to develop a brochure to
promote the Idaho Office of Energy Resource's low interest loan program to assist in the
fuding of customer energy efficiency projects. These promotional brochures were sent
to seven insulation contractors paricipating in the program who were encouraged to pass
the information along to their customers to help faciltate project completions.
Changes outlined in the last report including splitting the clothes washer category into
two tiers and offering a higher incentive for a higher effciency machine combined with a
reduced incentive for the machines at the lower end of the efficiency scale, reducing
and/or capping incentive levels for insulation on a per site basis, and combining eligible
water heater ratings and sizes have all been assessed and are scheduled to take effect on
May 1, 2008. At the same time, the Company wil make additional changes including
offering lighting incentives on a year round basis, adjusting incentives for evaporative
cooling equipment and adding an incentive for heat pumps. These changes are all

The Idaho Refrigerator Recycling Program is available to Idaho residential customers via
Schedule 117 and operated by a third-party program administrator. The discarded
appliances are taken out of use permanently and recycled in an environmentally
responsible manner to avoid resale on the secondary appliance market/re-entry into the
market. To paricipate customers call an 800 number to schedule a pick-up. Advertising
as well as utilty chanel communications such as the web site, bil stuffer, etc., inform
the customer about the offer. In addition to a cash incentive, participants receive an
energy efficiency packet consisting of ENERGY STARiI-certified compact fluorescent
light bulbs, refrigerator/freezer thermometer, and energy education materials.

The changes outlined in the last report including reducing the cash incentive and
renegotiating vendor delivery costs to further improve cost effectiveness were completed
in 2007. These changes were based on market analysis by the program administrator and
informed by updated program evaluation results. The cash incentive level, the deemed
savings per units and the tariff expiration date were modified in June 2007 through advice
filing 07-09. As a result of this filing, the $40 customer incentive was lowered to $30.
Changes in incentives and savings reporting were effective on August 1, 2007. Initial
results since the lowering on the cash incentive indicate no measurable impact in
customer interest/paricipation as a result of the lower incentive amount.
Low Income Weatherization
This program for income-qualified households is described in Schedule 21 and
administered for Rocky Mountain Power through Eastern Idaho Community Action
6
Rocky Mountain Power Idaho 2007 Anual Report
Parnership (EICAP) in Idaho Falls and South Eastern Idaho Community Action Agency
(SEICAA) in Pocatello. These parnerships allow for leveraging of Company funding
available to EICAP and SEICAA with federal grants, increasing the number of homes
served. During 2007, Rocky Mountain Power provided an incentive that covered 50%
from January through March and on April 1 the incentive increased to 75% of the cost of
approved energy effciency measures. The increase was driven by a Company
commitment to re-evaluate the cost benefit of changing its curent practice of matching
50% of federal contributions to matching a higher percentage. This was intended to
furher stretch federal funding and allow for a greater number of homes to be competed
anually further helping income qualifying customers address their energy expenses.
Customers with incomes at or below 150% of federal poverty guidelines may qualify.
Participants can be either homeowners or renters and reside in single-family homes,
manufactured homes or aparments to receive the services at no cost.
Table 4 sumarizes program activities. The energy savings estimate is based on measure
savings documented in an analysis dated August 30, 2006 completed by Quantec. An
impact evaluation to determine actual kWh savings wil be completed in 2010.
Expenditures of$101,287 are those paid by Rocky Mountain Power only. Of the
expenditures, $90,449 is for agency incentives with the balance ofthe costs attributable
to utilty administration. Funds received by the agency from other sources are not
included.

Rocky Mountain Power Idaho 2007 Annual Report
The average cost covered by Rocky Mountain Power per home for this program was
$1,739. Program changes were approved and effective as of April 1,2007. Revisions
include increasing Rocky Mountain Power's incentive from 50% to 75% on approved
measures and the addition of electric water heater repair and replacement and health and
safety measures (related to electricity usage).
Non-residential Energy Efficiency
Irrigation Energy Savers
Irrigation Energy Savers is described in Schedule 155 and is available to Idaho irrigation
customers taking retail service on Schedule 10. It is designed to be the energy efficiency
complement to the Schedule 72 & 72A Load Control Program. The Irrigation Energy
Savers program is delivered via a third-pary program administrator and has the following
components:
. Equipment Exchange - Provides new stadard brass sprinkler nozzles to replace
worn ones on hand lines, wheel lines and solid set sprinklers systems. Gasket and
drain equipment also qualifies.
. Pivot and Linear Equipment Upgrades - Incentives are provided for certain pivot
and linear system measures including sprinkler packages and regulators. The list
of prescriptive incentives is not designed to be exhaustive and other pivot
measures are eligible for incentives if energy savings can be calculated and the
customer incurs costs to make the changes.
. System Consultation - This service provides a simple site specific audit of a
customer's irrigation system to promote irrigation management and identify
energy savings opportunities. This consultation provides information prior to a
full pump test.
. Pump Testing - The pump test includes directly measurng pump lift, flow,
electrical demand and system pressures and is performed after the pump has been
screened and the owner's financial criteria understood.
. System Analysis - the program provides energy engineering to quantify costs and
savings for system changes which are generally the results of a grower needing to
make some production driven changes to irrigation equipment. Incentives are
based on a standard formula tied to costs and first year energy savings.
8
Rocky Mountain Power Idaho 2007 Annual Report
The Energy Savers program was introduced in 2006 and much of the early paricipation
and savings were derived from equipment exchange measures. During 2007, participation
of pivot and linear upgrade measures showed a steady increase. Many irrigators are
showing an interest in the installation of drives on their systems so requests for system
consultation and system analysis have increased substantially over the prior period.

While the program services and offers are subject to fuding availability per the terms of
Schedule 155, allocated funding was adequate for requested paricipation in 2007. As
described in Case No. PAC-E-08-01, Rocky Mountain Power is seeking to re-procure for
program administration services to help ensure program delivery remains competitive and
delivered by a vendor with superior irrigation and electric energy efficiency experience.
The curent program administrator wil continue to offer the prograr's services during
this process and will be requested to submit a revised proposal for Company
consideration against other delivery vendor proposals. ...~
FinAnswer Express
The FinAnswer Express program is described in Schedule 115 and is available to Idaho
business customers (other than Schedule 10). This program is designed to help customers
considering new or replacement lighting, motor, and HVAC (as well as other types of
equipment) to purchase and install high efficiency equipment. This program is designed
to operate in conjunction with the Energy FinAnswer program. Both new construction
and retrofit projects are eligible with equipment eligible for incentives in retrofit projects
but not for new construction incentives.
9
Rocky Mountain Power Idaho 2007 Annual Report
Based on experience in other Company jurisdictions, the Company expects many of the
Idaho projects to be originated and supported by trade ally networks as described below.
Trade alles are the best source for disseminating program information which occurs
through both trade ally advertising as well as point of purchase communcations. To
support this important market channel, the FinAnswer Express program provides
specialized trade ally support, through the use of a hired trade ally coordinator, for larger
program opportunities such as lighting, motors and HV AC equipment. This specialized
support has helped the Company meet planing projections with twenty-one trade alles
signing paricipation agreements program to date.
In addition, the program contains provisions for program-paid energy analysis to deliver
energy savings calculations, upon customer request, for energy savings measures not
specified in the prescriptive incentive table.

kWh 1,416,469
Expenditues $181,556lU
Incentives $107,848
Paricipants 52
This program's activity and savings potential has been restricted by its allocated funding
caps in both 2006 and 2007. Many projects that require custom analysis, which are
typically directed to the Energy FinAswer program in other markets, are requesting
analysis and incentive offers through the customer provision of the FinAnswer Express
program. This is occuring due to the program being the only Company offering for
business customers who are not on Schedule lOin Idaho. The Company is managing the
demand for business program services through a first come, first served approach and the
development of a waiting list for analysis and incentive offers, pending additional
funding. Currently, the waiting list has approximately 20 customers with requests totaling
approximately $180,000. Enhancements to the FinAnswer Express program, as well as
the introduction of the Energy FinAnswer program, are more fully described in the
Company's pending Case No. PAC-E-08-01. Case No. PAC-E-08-01, if approved, wil
effectively help accommodate the backlog of customer service requests and provide for
more tailored services to meet the analysis requirements curently being driven into the
more prescriptive program.

Rocky Mountain Power Idaho 2007 Anual Report
Northwest Energy Efficiency Alliance
The Northwest Energy Efficiency Allance (NEEA) is a non-profit organization working
to encourage the development and adoption of energy efficient products and services.
NEEA is supported by the region's electric utilties, public benefits administrators, state
governents, public interest groups and efficiency industr representatives.
The Company provides fuding for NEEA through a multiple year commitment to
support their activities in Idaho and Washington. NEEA activities for all sectors are fully
described on their web site at ww.nwallance.org. Funding for NEEA during 2007 was
$360,534. Energy Savings results reported by NEEA and allocated to Idaho durng the
same period were 3,504,000 kWh.
For the results displayed in the next section, energy savings from NEEA activities were
allocated to customer sectors based on information provided by NEEA. This allocation is
based on region-wide NEEA results by sector. The Idaho fuding was allocated to
customer sectors in the same ratio as the energy savings.
In addition to funding, the Company paricipates in the sector advisory groups and
provides input on NEEA activity effectiveness as well as the coordination between local
energy efficiency delivery and NEEA activities. We continue to work with NEEA
regarding ways to increase their activities and results across all sectors and in smaller and
more rural markets such as Rocky Mountain Power's Idaho service area.
Overall Revenues, Expenditures and Results
This section provides information about how fuds were collected and spent by customer
sector. It also includes information about which customer sectors are generating the
results. As outlined in the Executive Sumar, this data covers January through
December of 2007. Monthly totals for expenditures and collections as well as the
carrying charge calculation are included in Appendix One. Expenditures and savings
results by program have been provided in the Demand-side Management Programs and
Activities section. The following information is based on revenue collected under
Schedule 191 and expenditures curently fuded by the same revenue. It does not include
the incentive for the irrigation load management program.

Alignment with Potential Study findings
Overall energy efficiency results (8,092 MWH) for this reporting period fall short of the
annual tagets identified as achievable (13,140 MWH) under a set of avoided costs
assumptions and estimates oflikely paricipation described in the Potential Study.
Idaho residential results (55%) is generally consistent with the Potential Study that
indicated approximately 45% of the total potential was available in the residential market,
but is likely over-weighted by the reduced business program performance as the result of
allocated fuding caps. The Potential Study identified the two top measures in the
residential sector as lighting and appliances which aligns with the 2007 results from the
Home Energy Savings program and Northwest Energy Efficiency Allance results.
Commercial and industrial results are underperforming with 20% of the total compared to
40% of the total identified in the Potential Study. This is consistent with funding cap
impacts. Irrigation results at 25% of the total are higher than the Potential Study
identified share of 15% of the total, but funding constraints in the other business
customer programs serve to over-represent this sector.
Program Cost Effectiveness
The cost effectiveness of individual programs operated by the Company during this
report period was calculated using actual expenditures and reported savings. An energy
efficiency portfolio level assessment is also provided. Deemed savings estimates where
applicable (primarily residential programs) were the same as those used in the planing
estimates.
Energy savings shown in this report are on a combination of net and gross. They vary by
program and are consistent with the prior anual report. Gross savings are used for Low
Income Weatherization, FinAnswer Express and Irrigation Energy Savers programs. Net
energy savings are used for the Home Energy Savings, See Ya Later programs. To fuher
improve consistenci with regional reporting, i.e, the Northwest Power and Conservation
Council's 5th and 6 Power Plan, savings in the next annual report wil be provided on a
gross basis with net savings included in the cost effectiveness analysis. All figures are
provided at the customer site. Line losses utilzing the 2004 line loss study are included in
the cost effective assessments.
Cost effectiveness calculations also used the net-to-gross assumptions used in the
planing estimates. The energy savings attributed to the program are shaped according to
end-use specific load shapes (the hourly calculation of when energy is used for the
various program measures being incented). Program costs and the value of the energy
savings are then compared on a present value basis with the Company's 2007 Integrated
Resource Plan (IRP) calculated decrement values for DSM savings. The decrement
14
Rocky Mountain Power Idaho 2007 Annual Report
values are fully shaped to represent the 8,760 hourly values that exist within a calendar
year. By matching the hourly savings with the hourly avoided costs, both energy and
capacity impacts are recognized and the California Standard Practice Manual cost
effectiveness tests were calculated to assess program cost effectiveness. The cost
effective analysis of the Irrigation Load Control program is based on capacity value since
energy usage is shifted and there are no energy savings. See the December report for a
full discussion. Results by program are displayed in the tables below.
The cost effectiveness provided in this report is slightly different than that provided in
Case No. PAC-E-08-01 as preliminar results. The change occurs in the Home Energy
Savings program and is based on final 2007 unit counts provided by the program
administrator. Reported energy savings do not change, however incentives and measure
costs used in the cost effectiveness calculations do change slightly. This change in results
flows to the residential program portfolio provided here as well as the overall portfolio.
