Rocky Mountain Power Idaho Annual Report
Executive summary
Rocky Mountain Power hereby provides its first report on Idaho demand-side
management activities. The report period covers activities from March 12 2006 through
March 31 , 2007. The start date coincides with the date demand-side management
program costs were permitted to be deferred and offset with tariff rider (Schedule 191)
revenues whose collection started with bills on May 1, 2006. The end date for this report
coincides with the last full calendar month prior to May 1 , 2007 for which complete
accounting data is available. This report is submitted in compliance with Idaho Public
Utilities Commission Order Number 29976. Results for the period are summarized
below.
Total Revenue 748 409
Total Expenditures 917 512
MWH 232
Rocky Mountain Power s objectives in offering demand-side management programs to
their customers are to acquire cost effective resources to help meet load growth and
system peaks and to provide tools for customers and the state to lower usage and demand
and reduce their electricity costs.
The program set and funding level for this initial period was designed to meet the
objectives in offering demand-side programs while at the same time demonstrating utility
program delivery expertise and assessing the willingness of Idaho customers to
participate and the level ofthat participation. Programs currently offered include a load
management program for irrigators, three residential and two business customer energy
efficiency programs. In addition, Rocky Mountain Power provides funding to the
Northwest Energy Efficiency Alliance commensurate with the retail loads within Rocky
Mountain Power s Idaho service territory in support of the regional partnership to
increase customer access to and adoption of energy efficiency technologies throughout
the states of Idaho, Washington, Oregon and Montana.
For most programs within this report (load control and Low Income Weatherization being
exceptions), this reporting period represents the first time these programs have been
available to Idaho customers. As a result, the programs were in (and may still be in) the
ramp up phase during this time frame. During this ramp up phase, the programs were
cost effective and participation levels were generally as expected absent limits affected
by funding constraints. Program activity is more fully described in the following sections.
During this period, business customers developed projects that reserved all the available
2006 and 2007 funding under the FinAnswer Express program. The Irrigation Energy
Savers program had adequate funding for the reporting period. This is expected to
change for the balance of 2007.
Demand-side management
Rocky Mountain Power Idaho Annual Report
The primary change Rocky Mountain Power will bring forward in 2007 will be revised
forecasts for individual programs with primary focus on the business programs. These
revised forecasts will be based on both updated participation estimates and changes being
analyzed for individual programs. These will be combined with a re-assessment of the
overall funding requirements for demand-side management programs in Idaho and
include funding available from other sources such as the Conservation Rate Credit
Program available through Bonneville Power Administration s demand-side efforts.
Rocky Mountain Power expects to bring these assessments and recommendations
forward by July 1 2007. Also, beginning in 2008 the company intends to revise the
reporting period for the Idaho annual demand-side management report to a calendar
reporting period in order to better align with the company s fiscal year calendar. As a
result, the next annual report will be provided on or before March 15, 2008 and on or
before March 15 every year thereafter.
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. Participants agree to
curtail their electricity use during certain periods of time in exchange for participating.
Customers specify which sites they wish to include in the program and choose the best
schedule option to meet their needs. A program specific report for the 2006 season, the
fourth year of the program s operation was completed and submitted to the Commission
on November 2 , 2006. Information in Table 1 and 11 are from the November 2, 2006
report. Enrollment and site installations for the 2007 season are is currently underway.

In addition, the Company is analyzing the impacts of recovering the participation credits
through the tariff rider mechanism, as is done for program incentives in all other
company programs, rather than through base rates.
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 party administrator hired by the company. Schedule 118 and the
program web site at www.homeenergysavings.net/idaho/home are part ofthe program
delivery infrastructure. This web site is accessible through the company web site at
www.rockymtnpower.net/Article/Article45165.html.Schedule 118 does not currently
limit the funding 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: post-purchase delivery to the
customer for the majority of measures and through a manufacturer buy-down for CFLs.
Buy-down results in lower retail prices for customers. While most incentives are offered
year round, the buy-down for CFLs is offered seasonally to complement other regional
offerings.
Incentives for most measures will be available regardless of who installs the product. For
cooling equipment installations and services incentive payments require a licensed and
pre-qualified contractor perform the work to ensure savings are delivered.
Program results reflect this was a ramp up period. Forty one retailer locations in fourteen
cities were recruited and signed participation agreements were provided training and
point of purchase materials. Customer participation was lower than originally planned
and is partially attributable to rural demographics and the speed with which retailers
agreed to participate. Participation has steadily increased through the reporting period.

Plans for 2007 include a full roll-out ofthe HV AC measures, increased targeted outreach
to retailers, coordination of cooperative marketing opportunities, promotional events and
selected on site Energy Star trainings. The following changes are also being analyzed
and may be incorporated into the program in the near future: splitting the clothes washer
category into two tiers and offering a higher incentive for a higher efficiency machine
combined with a reduced incentive for the machines at the lower end of the efficiency
scale, assessing the effect of reducing or capping incentive levels for insulation on a per
site basis, comparing window specifications to local availability and resulting
incremental prices and combining eligible water heater ratings and sizes.
Funding availability restrictions are not currently in effect for this program, but
forecasted participation may require that they be introduced unless available funding is
increased.
See Va Later Refrigerator
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 to avoid resale on the secondary
market. To participate customers call an 800 number to schedule a pick-up. Advertising

as well as utility channel communications - web site, bill stuffer, etc. - inform the
customer about the offer. A $40 incentive per unit is provided to residential customers for
a maximum oftwo working refrigerators and/or freezers. In addition, participants receive
an energy efficiency packet consisting of an ENERGY ST ARQ\)-certified compact
fluorescent light bulb, refrigerator/freezer thermometer, and energy education materials.

The current Schedule expires on August 1 , 2007. The company is currently reviewing the
program s performance and requirements and is considering reducing the cash incentive
and renegotiating vendor delivery costs to further improve cost effectiveness. The
Company plans on filing a revised Schedule for this program sufficiently in advance of
the expiration date to provide a continuous program offering for Idaho customers.
Available funding will be assessed at that time and a funding availability clause may be
added.
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
Partnership (EICAP) in Idaho Falls and SouthEastern Idaho Community Action Agency
(SEICAA) in Pocatello. These partnerships allow for leveraging of Company funding
available to EICAP and SEICAA with federal grants, increasing the number of homes
served. During 2006, Rocky Mountain Power provided an incentive that covered 50% of
the cost of approved energy efficiency measures. Prior to January 12, 2006 incentives
were available to EICAP and SEICAA on weatherization services in electrically heated

homes only. Changes in January 2006 added incentives for the installation of additional
cost-effective non-shell related measures including Energy Star rated compact fluorescent
light bulbs, refrigerators and water-saving measures in homes with electric water heaters.
The changes also made incentives available on services one time per measure, but up to
two times per home to allow for the installation of new technologies and products that
were previously not considered cost-effective.
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 apartments to receive the services at no cost.
Table 4 summarizes program activities. The energy savings estimate was determined
through agency audit results and reported by EICAP and SEICAA. An impact evaluation
to determine actual kWh savings will be completed in late 2009. Expenditures of
$165 678 are those paid by Rocky Mountain Power only. Funds received by the agency
from other sources are not included.

example, no compact fluorescent light bulbs, low flow showerheads or aerators were
installed by the agencies during this reporting period. However, both EICAP and
SEICAA recently started installing compact fluorescent light bulbs.
Additional program changes were approved and effective as of April 1 , 2007. Revisions
include increasing the Rocky Mountain Power incentive from 50% to 75% on approved
measures, and the addition of approved measures including electric water heater repair
and replacement and health and safety measures that are related to electricity usage. The
program results incorporating these changes will be included in the next annual report.

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 Load Control Program. The Irrigation Energy Savers
program is delivered via a third- party program administrator and services are subject to
funding availability. Available program funding is posted on the Rocky Mountain Power
web site. The program has the following components:
Nozzle Exchange - Provides new standard brass sprinkler nozzles to replace worn
ones on hand lines, wheel lines and solid set sprinklers systems. Gasket and drain
equipment also qualifies.
Pivot Measure Incentives - Incentives are provided for certain pivot 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.
Pump Screening & Water Management Consultation - This service provides a
simple 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, Repair and Replacement - The pump test includes directly
measuring 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 Modification Repairs and Replacement - the program provides
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.
This program was introduced during 2006 and is in the ramp up phase. Since the
introduction occurred when plans for the growing season were already underway, most
growers utilized the instant savings measures, i., nozzle exchange. A few sprinkler
packages for pivot equipment were processed after the 2006 growing season ended. Most
irrigation equipment suppliers signed participation agreements. Available funding was
adequate for the period covered in this report.

Participation is forecast to be constrained by available funding during the 2007 season
driven by increased requests for water management consultations and pump checks and
system re-designs. These service requests will be in addition to equipment exchange
participation. The need for changes (if any) to the offer for 2008 will be analyzed based
on the 2007 season results when available. Changes will be analyzed under both funding
constrained and increased funding scenarios.
FinAnswer Express
The FinAnswer Express program is described in Schedule 115 and is available to Idaho
business customers (other than Schedule 10). The program is subject to funds availability
which is posted on the Rocky Mountain Power web site. This program is designed to help
customers considering new or replacement lighting, motor, and HV AC (as well as other
types of equipment) to purchase and install high efficiency equipment. Both new
construction and retrofit projects are eligible. Incentives for new construction are based
on equipment that exceeds code requirements, so some equipment eligible for incentives
in retrofit projects would not be eligible for incentives for new construction incentives.
In addition, there is a custom incentive calculation for measures not listed on the
prescriptive incentive tables. While the Company expects many of the Idaho projects
be originated and supported by trade ally networks (see below), the program contains
provisions for program-paid energy analysis to deliver energy savings calculations to
customers upon request.
Many customers learn about the program and develop projects with trade allies who sell
or install equipment which qualifies for incentives. To support this important market
channel, the FinAnswer Express program provides trade ally support for lighting, motors

and HV AC equipment dealers and trade ally participation has met planning projections
with seventeen trade allies signing participation agreements.

Program performance
kWh 699 109
Expenditures $203 896'
Incentives $62 366

Changes for this program are being analyzed in context of available funding. There is
currently a waiting list of customers requesting services and incentives from the program
and this condition also occurred during most of 2006. Current forecasts indicate this
demand is very likely to continue. As such, program changes are grouped into those that
could be made within available funding and those requiring additional funding. Within
available funding, Rocky Mountain Power is analyzing the incentive levels, equipment
classifications and equipment eligibility (i. e. LED traffic signals) within the lighting
equipment category. These changes alone would not significantly increase funding
availability. If additional funding was available, changes comparable to those made in
Utah and Washington would be made to the Idaho program. These changes including
offering prescriptive incentives for certain refrigeration equipment and simplified
analysis and standard offer type incentives for comfort cooling chillers.
Northwest Energy Efficiency Alliance
The Northwest Energy Efficiency Alliance (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 utilities, public benefits administrators, state
governments, public interest groups and efficiency industry representatives.
The Company provides funding 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 www.nwalliance.org. Funding for NEEA during this 15
month reporting period was $441 291. Energy Savings results reported by NEEA and
allocated to Idaho during the same period were 6 237 120 kWh.
7 Includes $54 825 of project specific engineering costs.8 Some customers completed more than one project
Demand-side management
Rocky Mountain Power Idaho Annual Report
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 funding was allocated to
customer sectors in the same ratio as the energy savings.
In addition to funding, the Company participates 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 funds were collected and spent by customer
sector. It also includes information about which customer sectors are generating the
results. As outlined in the Executive Summary, this data covers the period from January
2006 though March 31 , 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

Program Cost Effectiveness
The cost effectiveness of programs operated by the Company during this report period
was calculated using actual expenditures and reported savings. Deemed savings estimates
where applicable (primarily residential programs) were the same as those used in the
planning estimates. Cost effectiveness calculations also used the net-to-gross assumptions
used in the planning 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 ofthe
energy savings are then compared on a present value basis with the Company
Integrated Resource Plan (IRP) calculated decrement values (August 2005 update of the
2004 IRP) for DSM savings. The decrement values are fully shaped to represent the
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 November 2 2006 report for a full discussion. Results by program are
displayed in the tables below.
