PREFACE
Idaho Power Company s (IPC) Demand-Side
Management (DSM) 2006 Annual Report
provides a review of the financial and
operational performance ofIPC's DSM
activities and initiatives for the 2006 calendar
year. These programs provide a wide range of
opportunities for all customer classes to balance
their energy needs with best-practice energy
usage to minimize consumption while realizing
the benefits of reliable electrical service.
During 2006, IPC continued to expand the
programs that began with the 2004 Integrated
Resource Plan (IRP), also known as the Energy
Plan, realizing significant gains in customer
participation, energy savings, and demand
reduction. IPC's 2006 Energy Plan laid the
groundwork for the planning and
implementation of future programs. This multi-
faceted~deavor included the addition of three
new DSM programs and set the course for
accelerated participation and energy savings. In
addition to the DSM programs identified in the
Energy Plan, IPC has also continued to pursue
other customer-focused DSM initiatives
including programs, educational opportunities
and regional market transformation.
While IPC's DSM activities throughout the past
year focused primarily on accelerated program
implementation and the planning of future DSM
programs, the year s activities also included the
continuing commitment to building program
infrastructure and the enhancement of customer
education programs. In order to accommodate
the accelerated program growth and
implementation, IPC reorganized and expanded
its DSM department. Program design and
implementation processes continued to further
integrate IPC field and support personnel to
better facilitate the building of customer
awareness and participation in the programs.
The details of the programs and activities that
follow in this report reflect the importance of
DSM programs and activities to IPC's balanced
commitment to demand-side resource
acquisition.
This DSM Annual Report is prepared to report
on IPC's DSM activities and finances
throughout 2006, to express IPC's future plans
for DSM activities, and to conform to the Idaho
Public Utilities Commission s (IPUC) Order
No. 29419 and the Public Utility Commission of
Oregon s (OPUC) Order No. 89-507.

EXECUTIVE SUMMARY
IPC's DSM programs grew significantly during
2006. The energy savings from IPC's 2006
DSM activities increased by 87%, and the
expenditures on DSM-related activities
increased by 71 % compared to 2005 results.
DSM activities throughout 2006 were focused
predominantly around accelerated program
implementation and the planning of future
programs and activities. IPC's commitment to
ongoing, new, and enhanced DSM programs
was reflected in many ways during 2006. IPC
completed its second full year of successful
implementation of programs identified in the
2004 Energy Plan. It was also the first year of
program development and implementation
lanning for the DSM resources identified in the
2006 Energy Plan. Three new DSM programs
were identified in the 2006 Energy Plan
targeting additional opportunities in the
Residential, Commercial, and Industrial
customer sectors, and reaffirming the
importance ofDSM programs to IPC's long-
term resource acquisition strategy.
Figures 1 and 2 show the accelerating historical
growth in expenditures and resource acquisition
from 2001 to the present.

Year
In addition to its DSM operational
achievements, IPC made significant progress in
the movement toward creating an economic
environment more supportive of demand-side
resource acquisition. During 2006, IPC took part
in a collaborative effort that included
representatives from the environmental
community and the IPUC. These efforts resulted
in two proposals filed with the IPUC in late
2006; one would remove financial disincentives
that exist for IPC as it implements DSM
programs, and the other would institute financial
incentives as a method to encourage a higher
level of cost-effective demand-side resource
acquisition.
IPC's two main objectives for DSM programs
are to:
1. Acquire cost-effective resources in order to
more efficiently meet the electrical system
needs; and
2. Provide IPC's customers with programs and
information to help them manage their
energy and demand use and lower their bills.
IPC achieves these objectives through the
development and implementation of programs
with specific energy, economic, and customer
Annual Report 2006 Page 3
Demand-Side Management Idaho Power Company
satisfaction objectives. When possible, IPC
implements identical programs in its Idaho and
Oregon service areas.
IPC relies on input from the Energy Efficiency
Advisory Group (EEAG) to provide customer
and public interest review of DSM programs.
Formed in 2002, and meeting multiple times
each year, the EEAG is comprised of
12 members representing a cross-section of
customer sectors, including residential
industrial, commercial, irrigation, retirees
low-income, and environmental interests. The
EEAG also includes members representing the
IPUC and the OPUC. In addition to the EEAG
IPC solicits further customer input through
stakeholder groups in the residential, irrigation
commercial, and industrial customer sectors.
IPC continued its contractual participation in
and funding of, the Northwest Energy
Efficiency Alliance (NEEA) during 2006.
NEEA's efforts in the Northwest impact IPC'
customers by providing behind-the-scenes
regional market changes, as well as structural
support, to transform IPC's local markets. IPC
continues to leverage the support provided by
NEEA in the development and marketing of its
local direct acquisition programs, resulting in
efficiencies at program implementation.
In 2006, IPC also continued its ongoing
participation in the Bonneville Power
Administration s (BP A) Conservation and
Renewable Discount (C&RD) program. IPC
operates several programs with C&RD funding,
including Energy House Calls and Rebate
Advantage. In 2006, BP A implemented a
replacement program for the C&RD program
called the Conservation Rate Credit (CRC)
program from which partial-year funding was
applied to program expense.
DSM Program Portfolio
Structure
The programs within the DSM portfolio are
offered to each of the four major customer
sectors: Residential, Commercial, Industrial
and Irrigation. Within each of these sectors are
individual programs designed to target
cost-effective demand reduction and energy
savings. The programs are categorized by the
operational method through which these savings
are realized: Demand Response Energy
Efficiency, Market Transformation, and Other
Programs and Activities. A brief description of
each of these operational categories follows.
Demand Response Programs
Demand Response programs are designed to
reduce customers ' electricity loads at specific
times of the day and year when electricity is
normally in short supply and the cost to supply
electricity is high. The goal of Demand
Response programs within IPC's DSM portfolio
is to reduce the system summer peak demand
thus minimizing the need for acquiring
higher-cost, supply-side alternatives, such as gas
turbine generation or open-market electricity
purchases. Demand Response is usually
achieved through the use of load-control devices
installed on customer equipment. The measure
, of program performance is the number of
kilowatts (kW) of reduced demand during peak
periods.
In developing effective Demand Response
programs for reducing system summer peak
demand, IPC has targeted residential customers
using central air conditioning and irrigation
customers using pumping equipment. Together
these two customer sectors represent
approximately 60% ofIPC's summer peak
demand.
Energy Efficiency Programs
Energy Efficiency programs focus on reducing
energy usage through identifying buildings
Page 4 Annual Report 2006
Idaho Power Company Demand-Side Management
equipment, or components where energy
efficient design, replacement, or repair can yield
significant energy savings. These programs are
applicable to all customer sectors. The targeted
measures range from entire building
construction to simple light bulb replacement.
Savings from these programs are measured in
terms of reduced kilowatthour (kWh) usage, or
megawatthour (MWh) usage for larger projects.
These programs usually supply energy benefits
throughout the year. Energy Efficiency offerings
in 2006 included programs in residential and
commercial new construction, school buildings
residential homes, and irrigation and industrial
systems, processes, and components.
Market Transformation
Market Transformation is a method of achieving
energy savings through engaging and
influencing large national and regional
organizations that influence the decisions that
impact the design of energy usage in products
services, and methods that affect electrical
power consumption.
Implementation of Market Transformation is
best achieved by combining common regional
or national interests to leverage, synergies. IPC
primarily achieves Market Transformation
savings through its participation in NEEA.
Other Programs and Activities
Other Programs and Activities represent a wide
range of small projects that are typically
research- and development-oriented. This
category also includes one-time opportunities to
realize DSM objectives that are not within the
purview of existing programs. These programs
cover any type of cost-effective project or
educational opportunity within the scope of
IPC's DSM mission. Past projects have included
facilitating small demonstration projects
featuring new technologies, supporting existing
DSM education opportunities in IPC's service
area, and developing new educational
initiatives.

Program Performance
DSM programs at IPC continue to grow with
significant increases in participation rates and
energy impact in the form of energy savings and
demand reduction. In 2006, participation in the
AlC Cool Credit program increased by 127%.
The Irrigation Peak Rewards and AlC Cool
Credit programs resulted in a reduction of
coincident system peak demand of
approximately 37 MW in 2006 (Table 2). The
four Energy Efficiency programs with their
genesis in the 2004 Energy Plan were the
Industrial Efficiency, commercial Building
Efficiency, ENERGY STARCID Homes
Northwest, and Irrigation Efficiency Rewards
programs. These programs resulted in annual
savings of37 814 MWh in 2006, which was a
171 % increase over the 2005 energy savings of
939 MWh for these programs.
In addition to the Energy Plan programs during
2006, IPC operated several other Energy
Efficiency programs targeting residential
customers: Weatherization Assistance for
Qualified Customers (W AQC), Energy House
Calls, Rebate Advantage, and Oregon
Residential Weatherization. IPC also continued
to expand compact fluorescent lighting (CFL)
market-penetration programs in 2006. These
Energy Efficiency programs added savings of
614 annual MWh in 2006. In conjunction
with the 2004 Energy Plan programs, the energy
savings from these programs totaled
428 annual MWh savings.
Additional significant energy savings continue
to be realized through market transformation
partnership activities with NEEA. NEEA
estimates that 22 337 MWh were saved in IPC'
service area during 2006.

DSM Expenditures
and Funding
Funding for DSM programs in 2006 came from
several sources. The Idaho Energy Efficiency
Rider and Oregon Energy Efficiency Rider (the
Rider) funds are collected directly from
customers on their monthly bills at a rate of
1.5% of base rate revenues, with monthly caps
on residential and irrigation customer
contributions. IPC also received funds from
BP A, which in 2006 were provided through
BPA's C&RD and CRC programs. DSM-related
expenses not funded through the Rider or BP
Page 6 Annual Report 2006

funds, including costs for administration and
overhead, are included as part of IPC' s ongoing
operation and maintenance costs that are tracked
for recovery through base rates. Total DSM
expenses funded from these sources were over
$11 million in 2006.

Figure 3 shows the relationships among the
2006 DSM program expenditures by operational
category. Direct program expenses include
customer incentives and other program-specific
costs. Administrative and overhead costs are
non-direct program expenses or costs not
directly attributable to a specific program.
Future Plans
Many ofIPC's DSM programs are selected for
implementation through its biennial Energy
Plan. The Energy Plan is a public document that
details IPC's strategy for economically
maintaining the adequacy of its power system
into the future. The Energy Plan process
balances risk, environmental, economic, and
other considerations in developing a preferred
portfolio of future resources that meet the
specific energy needs of IPC and its customers.
The Energy Plan is updated every two years to
reflect changes in supply costs, demand for
electricity, and other factors. This approach to
resource planning is similar to the approaches
used by other utility companies, as well as
regional power planners such as the Northwest
Power and Conservation Council (NWPCC).
Shortly after IPC released its 2004 Energy Plan
NWPCC released its Fifth Power Plan, a
comprehensive 20-year energy strategy for the
Pacific Northwest. Both plans called for
increased levels of DSM resource acquisition.

During the Energy Plan development process
IPC conducts extensive research and analyses to
identify an optimal mix of supply- and
demand-side resources. IPC also relies on input
and guidance from the IRP Advisory Committee
as it selects its preferred resource portfolios. The
programs identified in the 2004 and 2006
Energy Plans represent IPC' s significant and
growing commitment to energy savings through
the implementation of DSM programs.
In addition to the 129 peak MW and 20 aMW
reductions identified in the 2004 Energy Plan
the 2006 Energy Plan calls for an additional
187 MW of demand reduction and 88 aMW of
energy savings by 2025. These additional
resources will come from new programs that
will be implemented during 2007 and beyond.
For example, the ENERGY STARCID Homes
Northwest and Building Efficiency programs
were developed as a result of the 2004 Energy
Plan and seek to increase energy efficiency in
Annual Report 2006 Page 7
Demand-Side Management Idaho Power Company
new buildings, while the 2006 Energy Plan calls
for programs that will increase energy efficiency
in existing structures and facilities in the
residential, commercial, and industrial sectors.
To meet the targets established in the
2006 Energy Plan, IPC plans to implement
several new programs targeted at residential and
commercial customers and to expand the
existing program for industrial customers. These
new programs will lead to a subsequent increase
in the level of energy savings and demand
reduction.
Northwest Power and
Conservation Council's Fifth
Power Plan Comparisons
NWPCC's Fifth Power Plan is a regionally
recognized document that is often used as a
benchmark against which Northwest utilities
resource-acquisition strategies are compared.
Most often, these comparisons are confined to
the areas of DSM and renewable resource
acquisition. While this type of comparison is
helpful when trying to evaluate a utility's plan
to acquire achievable DSM resources over the
long-run, year-to-year comparisons are likely to
provide less-relevant information.
IPC's Energy Plan identifies a diverse set of
resources that meet specific energy needs in
each year during the planning period. As a
result, there are many factors that influence the
level and type of DSM resources IPC plans to
acquire in any specific year. In the 2004 Energy
Plan, IPC identified an immediate need for
resources that could serve the growing summer
peak loads. With that in mind, the 2004 Energy
Plan primarily selected DSM resources that
targeted energy savings and demand reduction
during the summer months. This DSM resource
acquisition approach resulted in less energy
efficiency savings, but more peak load reduction
savings than identified in the Fifth Power Plan.
When the DSM resources identified in the 2004
Energy Plan are combined with the DSM
resources identified in the 2006 Energy Plan
the long-run energy efficiency and load
reduction targets under both the Energy Plan
and the Fifth Power Plan are closely aligned.
Customer Satisfaction
Customer satisfaction is a key consideration in
IPC's program design, operations , and
management. IPC utilizes surveys, focus groups
stakeholder input, and input from the EEAG and
IPC field personnel. This information and input
is used during the design and modification
phases of program development and throughout
each program s life.
In 2006, the W AQC program developed a
satisfaction survey for participants and began
mailing the survey in December. This survey
inquired about reduced heating and cooling bills
and the level of comfort achieved as a result of
the program s measures. In addition, the survey
asked for information regarding the number and
types of additional energy-saving ideas that the
customer implemented. The survey results will
provide guidance when future modifications to
programs are considered.
IPC's commercial Building Efficiency program
utilized post-participation satisfaction surveys to
measure customer satisfaction, and these
surveys showed that 94% of participants felt
that they received excellent service and value
from IPC.
Another measure of customer satisfaction is the
retention rate of on-going programs. IPC has
experienced high customer retention in the
AlC Cool Credit program with an attrition rate
ofless than 3%. The majority of attrition was
attributed not to satisfaction, but rather necessity
associated with customer relocation from an
existing residence. The attrition rate for the
Irrigation Peak Rewards program is 15%;
however, it is difficult to determine the portion
of this rate associated with program satisfaction
due to the dynamics of the agricultural industry.
Non-program-related influences include loss of
Page 8 Annual Report 2006

agricultural customers as farms are sold
land-lease changes, and crop rotation practices.
The results ofIPC's Quarterly Customer
Satisfaction Survey have shown steady
improvement over recent years as the percent of
customers who have a positive perception of
IPC's energy conservation efforts has continued
to increase. This trend was steady until the most
recent measurement period when a slight dip
was recorded. Customers' positive perception of
IPC's conservation efforts increased from 39%
in early 2003 to 45% in late 2006, which is a
15% increase overall. IPC continues to expand
its customer satisfaction measurement activities
to identify actionable areas of improvement.

DSM Annual Report Structure
This report's presentation structure is based on
customer sector (categorized by Residential
Commercial, Industrial, and Irrigation). Market
Transformation and Other Programs and
Activities are also presented in separate, but
similar categories.
Within each of the customer categories
individual program performance is presented by
operational category beginning with Demand
Response programs followed by Energy
Efficiency programs. The individual program
summaries are presented with an overview of
operations and results, including customer
participation, energy and demand impact, and
plans for 2007.
The appendices to this report provide additional
detailed program activity and performance data.
In keeping with energy efficiency reporting
convention, the energy savings presented in this
report are one-year (2006) totals. These annual
values do not represent the total life savings
associated with the single-year acquisition
expenditure. Total life savings are the sum of
the recurring annual stream of energy savings
associated with a given efficiency measure. The
duration of the stream of savings differs by
measure and program. Appendices 3 and 4 show
the measure-life associated with each program
in the DSM portfolio.

RESIDENTIAL SECTOR
OVERVIEW
Residential customers represent IPC' s largest
customer sector with over 387 000 accounts.
The sector grew 3.3% over 2005, adding more
than 12 000 accounts. The residential sector
represents approximately 36% of total system
energy sales.
Programs
Programs available to residential customers
include one Demand Response program and five
Energy Efficiency programs. The Demand
Response offering is the AlC Cool Credit
program, which achieves peak demand
reduction by cycling customers' central air
conditioners. The Energy Efficiency programs
include W AQC, Energy House Calls, Rebate
Advantage (for manufactured homes),
ENERGY STARCID Homes Northwest (for
new-home construction), and Residential
Retrofit-Lighting. Programs under
development in 2006 included Residential
Retrofit-Cooling and elements of Residential
Retrofit-Lighting.
Results
The total sector annual energy savings increased
by over 50% from 7 520 MWh in 2005 to
284 MWh in 2006. Summer peak demand
reduction from the A/C Cool Credit program
more than doubled to 5.6 MW.
Overall, participation rates for the sector are up
over 75% compared to 2005. Participation in the
programs selected as a result of the 2004 Energy
Plan is up 120%, and CFL distribution is up
nearly 150%.

Plans
The substantial growth in energy savings
identified in IPC's Energy Plans will be
achieved from both new and existing programs
in 2007 and beyond. New programs
encouraging customers to retrofit their
residences with higher efficiency equipment
will focus on ENERGY STARCIDlighting
(Residential Retrofit-Lighting) and efficient
cooling measures (Residential Retrofit-
Cooling).
Plans for the residential sector in 2007 also
include an update to a 2004 assessment of
energy savings potential in the residential
sector. The new study will focus on updating
specific measure-potential unique to IPC'
service area in 2007 and beyond.
IPC realizes the importance of customer
satisfaction in achieving the level of program
participation needed to reach the energy-savings
targets and plans to continue implementing a
formal customer satisfaction process to increase
the availability of quantifiable customer
satisfaction information.
In addition to program-specific work, IPC
anticipates increasing program participation and
satisfaction by increasing its efforts in energy
efficiency education for residential customers.
Through this enhanced effort, IPC hopes to
increase customer understanding of how
program measures improve a home s efficiency
and comfort.

Description
AlC Cool Credit is a voluntary program for
residential customers. Originally developed as a
pilot program in 2003 and 2004, the program
was selected in the 2004 Energy Plan for
implementation in 2005. The program, through
the use of communications hardware and
software, enables IPC to cycle participants
central air conditioners via a direct load-control
device installed on the air conditioning unit.
Participants receive a monthly monetary
incentive for participating in the program during
the summer season. This program enables IPC
to directly reduce system peaking requirements
during times when summer system demand is
high. Presently, the program is available to
Idaho residential customers in Ada County,
Canyon County, and the Emmett Valley.
Cycling of air conditioning units is achieved
through the use of individual radio-controlled or
power line carrier (PLC) switches installed on
customer air conditioning equipment. These
switches cycle customer air conditioners on and
off using a cycling period that is initiated on the
day before, or the day of, a cycling event. Under
this program, IPC may cycle participants' air
conditioners for up to 40 hours each month for
the months of June, July, and August.
Results
IPC initiated 22 load-control events between
June 13 and August 21 2006. The majority of
control events were four hours in duration at a
50% cycling rate (one-half of the participants
cycled off concurrently). During three events in
2006, the cycling rate was 66%. One cycling
event was at a 100% rate, which only lasted nine
minutes, but allowed IPC to test the program
full shed capabilities without causing
unnecessary customer discomfort.
Participation
The total number of program participants by the
end of 2006 was 5 369. This total included 178
participating customers in the Emmett Valley
utilizing the PLC system. Installations occurred
year-round in 2006, as supported by the
on-going, direct-mail campaigns. As one might
expect, installations are relatively low during
the non-summer months. However, marketing
efforts were increased in the fall of 2006
resulting in higher-than-average non-summer
sign-ups late in the year. These efforts included
large direct mailings from October through
November and the initiation of a weekly
direct-mail campaign directed toward new IPC
customers. In December 2006, these weekly
mailings to new customers averaged 300--400
each week.
Customer response rates for the regional
direct-mail marketing program were 4.65% for
Ada County, 2.23% for Canyon County, and 3%
for the Emmett Valley.
Demand Impact
The demand effects of this program have been
relatively stable over the past three years. On
average, IPC expects a 1.05 kW demand
reduction per participating household per hour
over the course of a 50% cycling event. The
Annual Report 2006 Page 13
Demand-Side Management Idaho Power Company
range of variability around this average has been
estimated through sampling studies to be
81 kW to 1.16 kW per cycling event. This
variability is caused by participant usage factors
which are impacted by weather and household
activity during cycling events. Increasing
cycling rates is shown to increase the overall
kW reduction of the program. However, IPC
primarily uses a 50% cycling rate for this
program in order to balance customer
satisfaction concerns with maximizing the
program s load-reduction potential.
Aside from significant per-unit peak impact, the
energy impact of cycling is relatively small.
Analysis shows that a participant s average
seasonal kWh usage decreases by .89 kWh due
to cycling. Although cycling appears to shift
some usage from cycling hours to non-cycling
hours, the net effect on kWh usage is negligible.
This level of load shift is also variable and is
primarily dependent on the cycling percentage
participant population usage profiles, and the
outside temperature during cycling events.
Plan for 2007
An escalated installation schedule will begin in
2007, as approximately 12 000 new participants
are planned to be added annually to reach the
goal of 40 000 program participants by the end
of2009. In order to meet the demand reduction
targets of this program, IPC plans to obtain
adequate control equipment, implement timely
marketing campaigns, and refine installation and
customer-care procedures in the upcoming year.
In past years, IPC has leased the communication
software. In 2007, IPC plans to purchase and
maintain this communications software to
operate the radio-controlled switches. This
change will improve response time and reduce
program life cycle costs.
IPC will continue to manage and monitor the
performance of the installation contractors to
ensure that customer satisfaction with the
program remains high as the number of
installations increases. As IPC increases its
marketing efforts in 2007, additional trained
installers will be utilized in order to maintain
low backlog levels.

Description
IPC launched the Energy House Calls pilot
program in October 2002 to evaluate the
viability of providing duct sealing and
additional efficiency measures to IPC customers
living in manufactured homes. Upon successful
completion of the pilot program, IPC rolled-out
the program to its entire service area in 2003. At
that time, the program was renamed Energy
House Calls for Manufactured Homes (formerly
known as Manufactured Home Energy
Checkups). This program was funded in 2006
through the BP A's C&RD and CRC funding
mechanisms.
BP A funds cover the participant costs and
include the following services and products:
Duct testing and sealing according to
Performance Tested Comfort System
(PTCS) specifications endorsed by the BP
Three compact fluorescent light bulbs;
Two furnace filters along with replacement
instructions;
Water heater temperature test for proper
setting;
Energy efficiency educational materials for
manufactured home occupants.
The program is managed under contract by Ecos
Consulting in partnership with Delta- T Inc.
both of whom have experience in managing and
providing duct-sealing service programs. These
partners coordinate local weatherization and
energy efficiency service providers to market
and perform the services. Quality assurance is
provided by third-party audits in compliance
with the BPA's C&RD and CRC guidelines.
Results
The year 2006 was the fourth full year of
operation for this program. The program
provided energy savings throughout the year
and earned IPC credits in the BPA's CRC
program.
Participation
Participation in this program was lower in 2006
than in the prior year. This was due primarily to
a continued focus on recruiting rural customers
and those who live in colder climates. This
focus represented a shift from the initial
program target sector of customers concentrated
in communities of manufactured homes. The
shift in focus to decentralized, rural
manufactured housing units required increased
marketing effort and travel time per housing
unit.
Energy Impact
The primary source of savings from the program
came from increasing the efficiency of the
heating system through improving air delivery
from the furnace through the duct system.
Improved delivery through the duct system also
provided energy savings associated with cooled
air where applicable.
Annual Report 2006 Page 15
Demand-Side Management Idaho Power Company
The installation of three CFL units into high
lighting-use areas also provided additional
energy savmgs.
The furnace filter and water temperature
evaluation services provided by the program are
designed to educate the occupants on
maintaining energy-efficient practices in the
future. The energy impact of these measures are
not quantified nor included in the total energy
impact of the program. Table 7 summarizes
2006 program service activity for Idaho and

Plan for 2007
In late 2006, IPC focused on determining the
saturation level of this program in the market to
assess whether or not to continue the program
into 2007. IPC found that a significant number
of qualified homes that can benefit from the
services of the program remain in the service
area; however, not everyone who is eligible will
choose to participate. Thus, as the Energy
House Calls program matures, it will reach a
point where it is no longer financially feasible to
promote this program to a small number of
receptive, potential participants.
While researching the Energy House Call
program s market saturation level and testing a
different marketing method, IPC will extend the
program for the first three months of 2007. In
the past, IPC has utilized bill stuffers, the
Customer Connection newsletter
advertisements in newspapers, and contractors
in the field to recruit new participants. In late
2006 and into 2007, IPC initiated a direct-mail
program to customers whose house-type data on
IPC's customer information system indicated
that it was a mobile or manufactured home.
Initial response rates to the campaign have been
at a rate of about 5%, exceeding the average
direct-mail marketing averages (for all-industry
marketing) of approximately 3%. Additional
benefits of this marketing method include better
geographic targeting and more productive
workload management.
In the first quarter of 2007, IPC will determine
if it is feasible to continue the program through
the end of 2007. IPC will continue to focus on
homes with a high potential energy savings.
Available housing units with such credits are
concentrated in Twin Falls, Pocatello, and in the
mountain communities in the Idaho and Oregon
servIce areas.
An additional change to the program for 2007 is
the increase of CFL installations per home from
three to five bulbs per home. This increase will
provide additional energy savings and reduced
customer bills.

Description
CIDT e ENERGY STAR Homes Northwest
Program is a regionally coordinated initiative
supported by a partnership of IPC, NEEA, and
the State of Idaho Energy Division to improve
energy-efficient construction practices for
single- family homes. The program was selected
for implementation in the 2004 Energy Plan.
The target of the program is to provide homes
that are 30% more energy-efficient than those
built to standard Idaho residential code. The
program focuses on the reduction of peak
summer demand by increasing the efficiency of
residential building envelope construction
practices and air conditioning equipment and air
delivery.
The primary market activities and incentives
provided by IPC are:
A $750 incentive per qualifying home to
participating builders ($1 000 for Parade of
Homes units);
Program management services to coordinate
the local partnerships between IPC, builders
and real estate service providers;
Educational and training activities for
residential new construction industry
partners;
Consumer marketing communications
conveying the benefits of ENERGY STARCID
homes.
Results
In 2006, the number of certified homes
increased by nearly 120% over 2005, from
200 homes to 439 homes. Participating builders
increased from 63 to 119. IPC implemented two
realtor training sessions and sponsored the
Parade of Homes shows in Ada, Canyon, and
Bannock counties. The marketing campaign for
this program included billboard advertising,
customer bill stuffers, print ads in real estate
tabloids, and public relations events. IPC
sponsored and hosted a national educational
event, the Energy and Environmental Building
Association s (EEBA) Houses That Work
Boise, attracting nearly 170 attendees.
Participation
While builder participation increased, the
number of certified homes fell short of the level
needed to meet the 2004 Energy Plan energy
target of 1 402 724 kWh or 675 homes for 2006.
Nearly 90% of the ENERGY STARCID homes
completed were built in the Treasure Valley.
The program s market share in 2006 was
approximately 5% of the total single-family
housing starts (based on preliminary estimates)
in IPC's service area.
Energy Impact
While there is variation in each home s energy
savings and demand reduction, the average
energy savings from an ENERGY STAR(ID
Home is 2 078 kWh, with a demand reduction

of2 kW based on a study completed for IPC by
Ecos Consulting.
Plan for 2007
IPC's 2007 energy target established in the
2004 Energy Plan for this program is
1,414 166 kWh, or approximately 681 certified
homes. In order to meet this goal, IPC will
engage in activities to:
Increase builder education and participation
in the program;
Increase realtor, subcontractor, lender, and
appraiser outreach programs;
Improve timeliness in quality assurance
inspections;
Increase participation in the Oregon service
area;
Develop and implement a comprehensive
marketing strategy to target consumers and
builders;
Continue to target the Treasure Valley
largest homebuilder for participation in the
program.

Description
IPC offers free energy audits for electrically
heated homes of customers within the Oregon
service area. Upon request, an IPC
representative visits the home to analyze it for
energy efficiency. An estimate of costs and
savings for specific measures is given to the
customer. IPC offers financial assistance for a
portion of the costs for weatherization measures
either as a cash incentive or with a 6.5% interest
loan.
Results
Participation
In 2006, 34 Oregon customers responded to an
informational brochure about energy audits and
home weatherization financing in 2006. Each of
the 34 customers returned a card from the
informational brochure indicating they were
interested in a home energy audit
weatherization loan, or cash payment.
Twenty-four audits and responses to customer
inquiries to the program were completed, five
customer responses were directed to Cascade
Natural Gas, and five follow-up calls to
customers had no response.
Energy Impact
None of the 2006 audit participants chose to
implement energy-saving measures during the
year.

Description
In 2003 , IPC launched a program to encourage
manufactured home buyers to purchase
energy-efficient Super Good CentsCID
ENERGY STARCID homes. The program
formerly called Energy Efficient Manufactured
Home Incentives, was renamed Rebate
Advantage at the start of 2004.
Rebate Advantage promotes and educates
buyers and retailers of manufactured homes
about the benefits of owning energy-efficient
models. The program offers financial incentives
using a two-pronged approach. Customers who
purchase a Super Good CentsCID/ENERGY
STARCID home and site it in IPC's service area
are eligible for a $300 incentive. In addition, the
salesperson receives a $75 incentive for each
qualified home sold. This program is funded by
the BP A.
Quality control and energy efficiency
specifications for qualified homes are
established by the Northwest Energy Efficiency
Manufactured Homes (NEEM) program. NEEM
is a consortium of manufacturers and state
energy offices in the Northwest. In addition to
specifications and quality control, NEEM tracks
the production and on-site performance of Super
Good CentsCID or ENERGY STARCID homes.
Results
The license to use the Super Good CentsCID
designation in the Pacific Northwest was
discontinued as of September 30, 2006. Initially,
BP A funding guidelines directed that, effective
October 1 , 2006, new homes must be
manufactured under ENERGY STARCID
standards and be certified as such by NEEM.
Subsequent to this decision, the BP A decided to
also accept the following homes for credit until
October 1 2007:
Manufactured homes certified by NEEM as
Super Good CentsCID
Manufactured homes sold as Super Good
CentsCID homes prior to October 1 , 2006
which subsequently receive the
NEEM-certified designation.
Participation
Participation in the program was fairly steady
throughout the year and similar in volume to
previous years. Participants typically are from
small, rural towns in IPC's service area. The
geographic reach of this program is noteworthy,
as seen in Table 8, in which Oregon homes
represent 14% of the total homes participating.
Approximately one-third of all manufactured
home dealers with sales in IPC's service area
are participating in this program.

Energy Impact
Savings in this program are largely due to
improvements in the shell of the home, resulting
in more efficient use of heating and cooling
resources. Manufacturers have some flexibility
in how they achieve a more efficient shell;
however, a common attribute of all homes in the
program is a sealed-duct delivery system.
Absolute savings are dependent upon the
heating and cooling climate zone in which the
home is sited. Energy savings for the year are
333 494 kWh.
While the program s focus is on overall energy
efficiency, peak demand impacts from reduced
air conditioning can be attributed to the
program.
Plan for 2007
The program will continue to be funded by the
BPA's CRC program in 2007. The 2007 goal
for this program is 150 certified homes. To
accomplish this aggressive target, IPC will
increase its manufactured home dealer outreach.

Description
The 2006 Energy Plan identified increased
residential efficiency programs associated with
lighting to capture a wider range of residential
efficiency measures. In 2006, IPC continued its
participation in regional lighting promotion
initiatives, sponsored by the BP A, called
Savings With a Twist (SWAT). Thus, the year
represented both development and
implementation for residential retrofit activities.
IPC has participated in recent, regional lighting
promotion programs in an effort to offer
energy-saving opportunities to residential
customers. In 2005, this activity was reported
under the SWAT program.
As a result of its commitment to new energy
savings targets developed in the 2006 Energy
Plan, IPC established the Residential Retrofit-
Lighting program to capture the wider range of
initiatives in the residential lighting arena. In
2006, the activities in this program were
associated with future program design, as well
as the SWAT initiatives, which are discussed
below.
IPC continued its partnership with the
Northwest ENERGY STARCID Consumer
Products program and the BP A to promote CFL
bulbs as a substitute for inefficient, incandescent
lighting. The SWAT program was designed to
highlight attractive promotional pricing and
motivate consumers to change out incandescent
bulbs with energy-efficient CFL units. Initial
program funding was through the Idaho Rider.
The program was launched in the fall of 2005
and ran through the early winter of 2006 (only
2006 impacts of the 2005 program are reported).
Given its success, the regional partners staged a
second program, initiated by BP A, for the fall of
2006.
Residential customers are the primary target
market. The primary goals of the programs were
as follows:
Build awareness of the efficiency and other
benefits of CFL lighting;
Highlight recent improvements in lighting
technology and quality;
Continue to build market penetration
especially in smaller, rural markets;
Capture incremental energy savings in
residential lighting use.
IPC's participation included funding paid
directly to manufacturers of CFL bulbs to
reduce or "buy-down" the retail price of select
CFL bulbs. The buy-down reduced in-store
prices to as low as $0.99 per bulb.
Results
Much of the program activity in early 2006
consisted of residual transactions associated
with program efforts initiated in 2005. IPC'
role during this phase was to simply support
retailers that had additional bulb inventories
available for sale in 2006. However, as the
Page 22 Annual Report 2006
Idaho Power Company Demand-Side Management
program was reinstated in the fall of 2006, the
region shifted its focus to recruiting stores that
served small, rural markets. Marketing was
focused on in-store, point-of-purchase collateral
to limit confusion among customers regarding
product-inventory availability. In addition, IPC
utilized its regional staff to support the program
with in-store visits.
For the reinstated fall 2006 initiative, the
program operated in both Idaho and Oregon and
was funded by BP A-CRC funds.
The per-bulb buy-down for the program that
operated in 2005 was $1.25 per bulb. The
per-bulb buy-down for the fall 2006 initiative
was $1.60. The increase created a higher
incentive for the manufacturers to ensure a more
reliable supply of bulbs.
Participation
Retailer participation has included both large
and small companies in hardware, drug,
grocery, and discount store channels throughout
the IPC service area. For the 2006 program
11 retailers and four manufacturers participated
in the program. Problems with product supply in
the 2005 program were addressed prior to the
implementation of the 2006 program. While not
part of the primary target audience for this
program, small commercial customers were
likely participants in the program because the
participating retailers also served this customer
sector. Energy savings totals are adjusted for
bulbs sold within IPC's service area but
assumed to be installed by out-of-service
participants.
Energy Impact
The energy impact of the program was initially
derived through guidance from the NWPCc.
The guidance called for derivation of savings
based upon the difference between incandescent
bulbs and CFL bulb replacement, and adjusted
for variable impacts due to regional differences
including heating impact, market saturation
rates, and lighting-usage profiles This method
yielded an estimated average energy savings of
39.6 kWh per CFL bulb and was used to
calculate the savings achieved under the first
program phase.
Since the second program phase was funded
through the BPA's CRC program, the energy
savings for that portion of the program was
estimated based on a number established by the
BP A. The regional average energy savings per
bulb established by the BP A was 32.8 kWh. The
difference in the savings-per-bulb rate under the
two methods was due primarily to differences in
market penetration in the region compared to
IPC's service area. For example, increased
penetration rates resulted in the installation of
newly purchased bulbs into lesser-used fixtures
resulting in fewer hours of usage and
subsequent savings.
Plan for 2007
BPA designed a new CFL mark-down program
called Change a Light, Change the Wodd that
focused on selling specialty bulbs through "big
box" retail stores during the spring of 2007. IPC
will participate in this new program and will
evaluate any other regionally-supported lighting
opportunities for implementation. BP A is
presently evaluating its fall 2006 program. It is
uncertain if the BP A will sponsor another CFL
promotion event similar to SWAT in the fall of
2007. Beyond these regional initiatives, IPC will
be targeting additional opportunities to make
ENERGY STAR CID -qualified lighting available
to a broader range of customers, and increase
the number of CFLs installed in the homes of
those customers who currently have some CFLs
installed.

Description
Weatherization Assistance for Qualified
Customers (W AQC) has been operating since
1989. The program provides funding for the
installation of cost-effective weatherization
measures in qualified owner-occupied and rental
homes that are electrically heated. These
enhancements enable low-income families to
maintain a more comfortable home
environment, while helping save energy and
money otherwise spent on heating, cooling, and
lighting.
The program is modeled after the u.s.
Department of Energy (DOE) Weatherization
Program. The DOE program is managed
through Health and Human Services offices in
Idaho and by the Department of Housing and
Community Services in Oregon.
IPC serves as the administrator of the program
in conjunction with the Community Action
Partnership (CAP) agencies serving the IPC
service area. Funding for the program is a
combination of federal government funds and
IPC base rates. The federal funds are distributed
to CAP agencies based upon u.s. Census data
of qualifying household income within each
CAP agency s geographic area of influence. The
agencies oversee local weatherization crews and
contractors for implementation. IPC funds the
program subject to cost effectiveness of
measures applied.
Results
The allowable annual average project cost from
January through September 30 2006 was
304. Idaho CAP agencies together averaged
294 for that time period. In October 2006
the annual average cost allowable per home was
raised from $2 304 to $2 826 per home to match
the state DOE program per-home average.
Expenditures for Health and Safety measures
were 7.5 % ofIPC's total project cost. IPC
allowed Health and Safety measures to be
funded up to 15% of the total project cost
annually.
Participation
Eight CAP agency executive directors signed
weatherization agreements with IPC in 2006.
Five of the eight are located in Idaho and three
are located in Oregon. The five Idaho agencies
completed a total of 540 projects. Oregon
weatherization departments completed projects
late in 2006 to be submitted to IPC for payment
and reporting in 2007.
The CAP agencies that have signed agreements
with IPC to provide weatherization services are:
Canyon County Organization on Aging and
Community Services (CCOA); El-Ada
Community Action Partnership (El-Ada);
Eastern Idaho Community Action Partnership
(EICAP); South Central Community Action
Partnership (SCCAP); South Eastern Idaho
Community Action Agency (SEICAA);
Malheur Council on Aging (MCOA); Harney
County Senior and Community Service Center
(HCSCS); Community Connections NE Oregon
(CCNO).

Energy Impact
Prior to the allowable average project cost
increase in October, the funded energy
efficiency measures by Idaho agencies averaged
096 kWh savings per home. With the recent
increase in allowable expense, average annual
energy savings per home increased to
567 kWh.
Two non-profit projects were completed with a
total of 74 927 kWh annual savings.
Table 9 shows IPC expenses for the program by
CAP agency and non-profit organizations for
Idaho and Oregon. Additional funding for the
program is provided by government funds made
available to the CAP agencies. In 2006, these
funds totaled $773 085.

IPC expects the program activity during 2007 to
maintain the same annual pace as that achieved
in 2006. To help ensure continued program
activity, IPC plans to be a party with
Community Action Partnership Association of
Idaho, Inc. (CAP AI) in a joint application
requesting the IPUC authorize continued
funding for W AQC at the level authorized in
Order No. 29505 issued May 25, 2004, in
Case No. IPC-03-13. It is anticipated that the
application will be filed with the IPUC in the
first quarter of 2007. A total of 467 dwelling
units are targeted for completion during the
year.
Annual Report 2006 Page 25
Demand-Side Management Idaho Power Company
Individual goals for Idaho and Oregon and
dwelling-unit types have also been established
as follows:
Idah0-434 dwelling units: 430 homes and
four non-profit-sponsored housing units;
Oregon-34 dwelling units: 33 homes and
one non-profit-sponsored housing unit.
Expected energy savings for these projects are
targeted at 2 757 000 kWh.

COMMERCIAL SECTOR
OVERVIEW
The commercial sector consists of over
59000 customers in IPC's service area
representing approximately 27% of total system
energy sales.
In recent years, most of IPC' s DSM efforts in
the commercial sector have been focused on
implementing energy efficiency measures in
new construction projects, which represent a
small, but important, subset of the potential
savings in the sector. Large commercial
buildings can achieve energy savings that are
only cost-effective at the time of construction
and would otherwise be lost. In 2006, it is
estimated there were approximately 1 200 to
500 new commercial buildings built in IPC'
service area with an equal number of
commercial building additions or major
renovations available for capturing this lost
opportunity.
Results
The total sector annual energy savings achieved
has increased by about 88% from 2005 to 2006
from 494 239 kWh to 927 909 kWh (Table 11).
Participation has increased even more
significantly. Completed energy efficiency
projects in 2006 were nearly three times those
completed in 2005.

Plans
The 2006 Energy Plan identified a significant
expansion for the commercial sector planned for
implementation in 2007.
This expansion targets existing commercial
structures with a wide range of energy-savings
measures that will be available to the entire
commercial sector, as well as a subset of
industrial customers (those served under
Schedule 19 and by special contract). A retrofit
program, Easy Upgrades, will provide these
same customers with streamlined access to an
array of menu options for energy-savings
measures.
In 2007, IPC plans to develop a commercial
energy efficiency education initiative similar to
a residential sector program developed in 2006.
In addition, improved customer satisfaction
evaluation and communication methods and
materials are continually being developed to
increase program satisfaction, awareness, and
participation.

Description
The Building Efficiency program is designed for
commercial customers involved in the
construction of new buildings or significant
construction projects. This program enables
customers to apply energy-efficient design
features and technologies to their projects. The
program was launched in Idaho in the spring of
2005 and expanded to Oregon in January 2006.
The Building Efficiency program offers a menu
of measures and incentives for lighting- and
cooling-efficiency options. The program
incentives also include funding for custom
projects, as well as additional incentives for
commissioning that ensures the systems perform
as designed.
Program marketing enlists architects, engineers
and other local design professionals to promote
the program. Program-related communications
also reach out to building developers, building
officials, and IPC field personnel.
Through this program, IPC is a primary sponsor
of the Boise Integrated Design Lab, which
provides technical assistance and training
seminars to local architects and designers. Much
of this activity is coordinated and supported
through NEEA's BetterBricksCID program.
Results
Program marketing and education activities that
began in 2005 continued and expanded in 2006.
By the end of 2006, IPC e-mailed program
updates to over 700 customers and design
professionals on a regular basis.
The expansion of this program into Oregon
resulted in the first Oregon project, completed in
September 2006. Also in 2006, IPC developed a
process to expand customer contact through
IPC's Customer Service Center to share
program information with customers engaging
in new or significant electrical projects.
Participation
Similar to 2005 , there were 38 projects that
submitted expressions of interest for future
projects in 2006. During 2006, 40 projects were
completed and received incentives, which was
significantly more than the 12 projects
completed in 2005.
Energy Impact
The Building Efficiency program exceeded
2004 Energy Plan targets for both energy
savings and demand reduction in 2006. The
annual energy savings increased by 43% over
2005, from 494 239 kWh to 704 541 kWh. The
peak demand reduction increased from 162 kW
in 2005 to 338 kW in 2006, which represents an
increase of 109%.
Plan for 2007
IPC plans significant modifications and
improvements to the program in 2007. With
input from a stakeholder group, the EEAG, and
IPC field personnel, the program measures
Annual Report 2006 Page 29

incentives, and eligibility requirements will be
changed for 2007.
In 2007, the program will feature four major
initiatives:
Open-up to more customers-The program
will be expanded to include customers
taking service under Schedule 19, where it
was formerly limited to those served under
Schedule 7 and Schedule 9;
Include more measures-The initial
program offering was limited to
10 measures; the revised program will
increase to 17. Beyond the additional
measures, some of the incentive levels and
requirements will also change;
Incentive payment cap increase-The single
project payment cap of $20 000 will be
raised to $100 000 in 2007;
Require a preliminary application-
Preliminary applications will be required forall future applicants.

Description
The Oregon Commercial Audit program has
been available to all Oregon commercial
customers since 1983. The purpose of the
program is to identify opportunities for
commercial building owners to achieve energy
savings. The program offering includes
evaluation (energy audit) and educational
servIces.
The primary method for communicating the
program benefits and offerings to the target
market is achieved through an annual mailing to
each customer in the commercial sector.
As was done in 2005 , IPC offered the Saving
Energy Dollars publication to customers who
wanted more information for saving energy and
reducing expenses.
The Oregon Energy Efficiency Rider provides
funding for this program. The program normally
incurres expenses from the production of
customer information packets and by the use of
third-party contractors to conduct energy audits.
In 2006, no expenses were charged to the
program (due to the fact that no new
publications were purchased) nor were any
contractor audits required.
Results
In October 2006, IPC completed its annual
mailing to all Oregon commercial customers.
The letter mailed to these customers notified
them of the availability of no-cost energy audits
and the availability of the IPC publication
Saving Energy Dollars. Last fall's mailing
resulted in a response from nine customers
requesting the Saving Energy Dollars
publication. Six customers returned requests for
energy audits, which were conducted by IPC
personnel.
Energy Impact
As an education-only program, the audit does
not develop measurable energy savings. Any
subsequent implementation of energy savings
measures was outside the scope of the program.
Plan for 2007
IPC is evaluating the potential for synergy
between the Oregon Commercial Audit program
and the planned Easy Upgrades program to offer
incentives for commercial retrofits in Oregon.
Options include adding Easy Upgrades program
information into the annual Oregon Commercial
Audit program mailing.

Description
The Oregon School Efficiency program was
initiated in late 2005 and realized energy
savings in 2006. The program operates in close
conjunction with the Oregon Department of
Energy (ODOE) in promoting energy-saving
upgrades for Oregon public school buildings.
The opportunity to partner with ODOE emerged
following the 2004 Energy Plan planning
process.
This program offering is an effective and
efficien~ vehicle to augment the school building
energy Improvement projects under the ODOE
umbrella through using IPC-provided incentives
and potential tax benefits.
Oregon School Efficiency incentive payments
for 2006 were based on $0.10 per annual kWh
savings. The Business Energy Tax Credit
(BETC) tax benefit pass-through can increase
the realized incentive by 25%-30% of a
participating school's project cost.
Through ODOE's school efficiency initiative
program infrastructure for marketing and
operations were in place prior to IPC'
Idaho Power Company
involvement, which reduced IPC's program
costs for energy savings.
Results
The first project was completed and paid in
February 2006. For the year, six projects
resulted in savings of 223 368 kWh.
Payments were made at school board meetings
providing a showcase opportunity for ODOE
and IPC providing a broad opportunity for the
local community to realize the benefits of the
program.
Participation
Five school districts, representing 35% of the
total districts in IPC's Oregon service area
committed to participate and four districts have
completed their projects.
Energy Impact
The program provided significant average load
reductions primarily through lighting retrofits;
however, summer load reduction was less than
average due to reduced consumption when
schools were not in session.
Plan for 2007
Plans for 2007 include phasing-out this program
and replacing it with a company-wide retrofit
program, Easy Upgrades. When that program is
introduced to Oregon customers, this special
school-only program will likely be discontinued.
Easy Upgrades will be offered through an
alternate application process, but will offer
similar incentives for potential, future public
school energy-saving projects.

INDUSTRIAL SECTOR
OVERVIEW
Traditionally, IPC's Industrial sector is
comprised of IPC' s largest individual energy
consumers. This sector includes customers
served under Schedule 19 and Special Contract
Customers. This sector consists of
130 customers and accounts for approximately
25% ofIPC's system energy sales. In order to
realize operational efficiencies, the Industrial
Energy Efficiency program is offered to all
customers with a minimum Basic Load Capacity
(BLC) of 500 kW or more. In 2006
approximately 300 Industrial and Commercial
customers qualified for this program, including
some of the larger commercial customers served
under Schedule 9.
Programs
The Industrial Efficiency Program represented
the sole program providing energy efficiency
initiatives to customers in 2006. The details of
the program are provided in the section that
follows.

Description
The Industrial Efficiency program was selected
for implementation during the 2004 Energy Plan
process. The program is offered to
approximately 300 large commercial and
industrial customers of IPC in both Idaho and
Oregon who have a BLC of 500 kW or more.
The program targets the acquisition of peak
demand reduction and energy savings through
the implementation of energy efficiency projects
at customer sites.
Operationally, the program provides the
following:
Training and basic education on energy
efficiency;
Energy auditing services for project
identification and evaluation;
Financial incentives for project
imp lementation.
The energy auditing, customer training, and
education services are key components in .
facilitating customer implementation of energy
efficiency projects at their facilities.
Operationally, interested customers submit to
IPC an application that identifies potential
projects applicable to their facilities. The
application must provide sufficient information
to IPC to establish a basis for viable
conservation projects. Project implementation
begins following finalizing the application with
terms and conditions of each party's obligations.
When possible, IPC conducts on-site power
monitoring and data collection to verify
information from the application process and
ensure demand reduction and energy savings are
obtainable and within program guidelines.
Large, complex projects may take as long as
two years to complete due to complexity.
Results
The Industrial Efficiency program increased
energy savings in 2006 by 60% over the prior
year, from 12 017 MWh to 19 212 MWh. This
program experienced a 67% increase in
completed projects and a 150% increase in
approved incentive applications, which
demonstrates that interest in this program
continues to grow.
Stakeholder meetings were held with industrial
customers, EEAG, IPUC, and IPC
representatives in early 2006 to review the
program. Recommendations for program
changes developed from these meetings
included the expansion of the auditing services
aspect of the program to include one detailed
energy audit per customer site annually.
Previously, one detailed energy audit was
allowed every three years per customer site.
In expanding the program s reach in 2006, IPC
also increased focus on working with the
Industrial Efficiency Alliance (IEA). .funded by
NEEA, the goal of the IEA focuses on energy
management in the food-processing sector using
Page 34 Annual Report 2006
Idaho Power Company Demand-Side Management
a top-down approach. IEA works with the upper
level management of organizations to develop a
corporate energy management policy. In 2006
three companies in IPC' s service area adopted
the IEA energy management policy.
Participation
IPC reviewed and approved a total of
60 applications for incentive projects in 2006.
Of these 60 projects, a total of 40 projects were
completed with 25 companies at 29 separate
locations in Idaho. One Oregon project was
approved in 2006 but not completed by
year-end.
IPC also increased activity in energy auditing
and education in 2006. Over 34 walk-through
energy audits were performed by IPC personnel
during the year.. In addition, a total of
12 scoping studies were performed by
independent energy service companies.
Customer training and education was another
factor in the overwhelming success of the
program in 2006. IPC sponsored a total of seven
workshops in conjunction with the IEA
Washington State University, the U.S. DOE
and the Idaho Department of Water Resources
Idaho Energy Division (IED). Approximately
200 customers participated in these workshops.
One of the workshops consisted of a new
approach to training called a "cluster." The
cluster training focused on compressed air
systems. The class was kept small and was
attended by at least two people from five
different companies. The first day of the
workshop consisted of the Compressed Air
Challenge Levell workshop developed by the
DOE. The second day consisted of team
mentoring by compressed air experts to help
each company develop specific action plans for
their facilities. Periodic follow-ups and ongoing
support are all part of the cluster approach to
training.
Energy Impact
The Industrial Efficiency program target was set
at 8 400 MWh for 2006. Actual savings
achieved were 19 212 MWh, exceeding the
target by over 128%.
Plan for 2007
For 2007, the program eligibility will be
expanded to include all Schedule 9
Schedule 19, and Special Contract customers
regardless of energy usage. However, the 2007
program will require a minimum energy savings
level per project in order to maintain the
program s cost-effectiveness. This expanded
customer group is comprised of approximately
924 Oregon customers and 21 761 Idaho
customers. The target for the 2007 Energy Plan
is 15 714 MWh.
In 2007, the program offerings will expand to
include the same options as the new commercial
retrofit program, Easy Upgrades (to be
introduced in early 2007), opening up additional
opportunities for the participants in the
Industrial Efficiency program.
The Easy Upgrades program will target
less-complex projects that do not require the
detailed engineering review and analysis.
Future plans also include the development of
enhanced program design and communication
materials to coordinate commercial and
industrial program implementation, promotion
and education.
The expansion of eligible customers and
program offerings in conjunction with the
anticipated levels of participation rates and
interest in the program will result in significant
future growth in activity and energy savings
attributable to the Industrial Efficiency program.

200 individuals with over 16 600 electrical
service locations. Other irrigation users, such as
golf courses and parks, are assigned to other
sectors and are outside the purview of the DSM
Irrigation programs.
The Irrigation sector represents approximately
30% ofIPC's summer peak load and 12% of
total system energy sales per year. The load for
this sector has not'grown significantly in recent
years; however, there is a yearly variation in
demand due primarily to the impact of weather
on irrigation needs.
Programs
IPC currently offers two programs to the
Irrigation sector: Irrigation Peak Rewards, a
demand response program designed to decrease
peak demand, and the Irrigation Efficiency
Rewards, an energy efficiency program
designed to encourage replacement or
improvement of inefficient systems and
components.
Results
The Irrigation Peak Rewards program provided
significant peak reduction during the summer of
2006 with an average load reduction of
23.9 MW and a peak reduction of31.8 MW.
The peak reduction reported by the program in
2006 was less than in 2005 due to changes in
how the participant load reduction was
distributed throughout the week.
Irrigation Efficiency Rewards participation grew
significantly from 2005 to 2006. The program
redesign, which began in 2006, offered
increased incentive levels and the addition of a
menu option program that offered incentives for
a wide range of upgrade able components. The
total energy savings increased from just over
000 MWh in 2005 to 16 986 MWh in 2006
while participation increased from 38 customers
to over 550.
Figure 8 provides a comparative perspective of
the 2006 irrigation direct program expense.

Description
The Irrigation Peak Rewards program was
initially implemented as a pilot program in
2004. Full implementation followed in 2005 as a
result of the 2004 Energy Plan planning process.
The program was developed after being selected
through the 2004 Energy Plan process. In 2006
the program also became available to IPC'
Oregon customers.
The voluntary program targeted agricultural
irrigation customers with pumps of
100 horsepower (hp) or greater with an
objective of reducing peak electrical load during
summer weekday afternoons. The program
utilizes pre-programmed, electronic
time-activated switches to turn off pumps of
participating irrigation customers during
predetermined intervals in exchange for a
financial incentive.
Voluntary participants selected one of three
weekly interruption options for the months of
June, July, and August. A monthly demand
credit was associated with each of the one-
two-, or three-day interruption options and paid
on the basis of the participating customer
monthly billing demand. Electronic timers are
programmed to turn off irrigation pumps during
the pre-programmed time periods associated
with the selected option. The following
interruption options and associated demand
credit incentives were available to customers in
2006:
One weekday per week, 4 p.8 p.
$2.01 per kW demand credit;
Two weekdays per week, 4 p.8 p.
$2.52 per kW demand credit;
Three weekdays per week, 4 p.8 p.
$2.76 per kW demand credit.
The incentive amount credited to customers
monthly bills was calculated separately for each
metered service point.
Results
IPC completed its second successful year of full
program implementation following the pilot
program in 2004, including offering this
program in the Oregon portion ofIPC's service
area. The Irrigation Peak Rewards program
achieved a peak demand reduction of
836 kW in 2006.
Participation
Participation in the program during 2006
remained largely unchanged from the prior year.
Participation rates from a service point
perspective (a customer may have more than
one metered service point participating in the
program) show the program achieved 23.3%
participation (906 service points out of
878 eligible service points). For 2006
893 participating service points were located in
Idaho, and 13 were in Oregon.
Based on number of customers rather than
number of service points, 229 customers, or
Annual Report 2006 Page 39
Demand-Side Management Idaho Power Company
20.2% ofthe 1 131 eligible customers, chose to
participate.
Demand Impact
Each summer, the program has produced
substantial and measurable impacts on peak
demand. Over the course of the 2006 summer
the program produced an average load reduction
of23.9 MW, with an average of27 MW load
reduction in the month of July. The maximum
load reduction occurred during the second half
of June, when an estimated 31.8 MW reduction
was achieved representing 106% of the
2004 Energy Plan target of30 MW of peak
savings. In 2005 , IPC chose to shape the load
reduction to be greater on Tuesdays
Wednesdays, and Thursdays than on Mondays
and Fridays. In 2006, IPC changed the
distribution of the load reduction to be equal
over all five weekdays, reducing the absolute
peak of the program relative to 2005. This
change in the peak reduction distribution was
done in response to IPC research, indicating
that, although statistically the system peak is
less likely to occur on Mondays and Fridays, the
. fact that it can happen on any weekday justifies
an even distribution in scheduling and
subsequent even load reduction for planning
purposes.
Plan for 2007
In cooperation with the Idaho Irrigation
Pumpers Association and IPUC staff, IPC
redesigned the program in the fall of 2006 with
the primary objective of increasing
participation, and subsequently, peak load
reduction. IPC received approval from both the
IPUC and OPUC to implement the proposed
changes to the program in 2007.
The changes to the Irrigation Peak Rewards
program for 2007 include increasing the
incentive amounts and decreasing the minimum
hp requirement from 100 hp to 75 hp. In
combination, these changes are expected to
increase the peak load reduction during summer
weekdays by approximately 3.9 MW.

Description
The Irrigation Efficiency Rewards program was
initially implemented as a pilot program in
2003. Full implementation followed in 2005 as a
result of the 2004 Energy Plan planning process.
The program is designed to improve the energy
efficiency of customers' irrigation systems by
providing a broad range of financial incentives
and educational programs designed to serve the
diverse needs ofIPC's irrigation customers. In
2006, IPC offered the program in both the Idaho
and Oregon service areas.
The array of available incentive categories
covers minor and major system improvements.
In order to meet the needs of such a wide range
of systems, two separate options were
developed. For major changes on new or
existing systems, the Custom Incentive Option
provides for component upgrades and
large-scale improvements. For systems where
small maintenance upgrades will provide energy
savings, the Menu Incentive Option is offered.
Specifics for each of these two incentive
alternatives are as follows:
Custom Incentive Option
Available for new or existing irrigation
system upgrades;
For new systems, incentives are the lesser
of:
$025 per kWh saved; or
10% of total project cost.
For existing system upgrades, incentives are
the lesser of:
Greater of $0.25 per annual kWh saved
or $450 per kW; or
75% of total project cost.
Menu Incentive Option
Based on specific component replacement;
Paid on predetermined, average energy
savings per component.
IPC reviewed and analyzed each proposal for a
system or component modification to determine
and verify the energy savings. IPC Agricultural
Representatives also provided energy audits to
customers to evaluate potential program
saVIngs.
In addition to incentives, the program provided
significant educational and training
opportunities for irrigation customers. IPC
Agricultural Representatives sponsored
coordinated, and participated in educational
workshops for irrigation customers. The
workshops provided customers with expert
Annual Report 2006 Page 41
Demand-Side Management Idaho Power Company
information and education across the service
area.
IPC Agricultural Representatives also engaged
agricultural irrigation equipment dealers in
training sessions to increase awareness and
product knowledge and to promote the program
throughout the irrigation equipment distribution
channel.
Marketing communication efforts provided
awareness and understanding of the program
offerings. They included direct mailing,
advertisements in agricultural publications
agricultural trade show participation, and
educational workshops.
Results
The Irrigation Efficiency Rewards program
realized 16 986 MWh of energy savings and
1 MW of peak load reduction in 2006 and
surpassed the 2004 Energy Plan targets by
227% and 96% respectively.
Participation
In 2006, 1 235 projects were completed with
irrigation customers, of which 138 were under
the Custom Incentive option, and 1 097 under
the Menu Incentive option. Incentive payments
to customers under the program options in 2006
totaled $2 477 598.
Energy Impact
The energy impact of the program is realized
from efficiency in irrigation energy use in the
summer months during both peak and non-peak
periods. Savings for 2006 were 5.1 MWof
summer peak savings and 16 986 MWh of
energy savIngs.
Plan for 2007
IPC plans to continue to operate the program in
2007. However, IPC plans to implement a few
modifications to the program based on
operational experience, along with input
received from EEAG, irrigation customers, and
irrigation equipment dealers. All of the
modifications are focused within the Menu
Option portion of the program and will take
effect in 2007.
The program changes will add two new
irrigation components to the Menu Option and
place additional caps on five of the existing
Menu Option items. IPC expects that these
changes will help to clarify the details of the
program for customers and maintain the
program s cost effectiveness into the future.

MARKET TRANSFORMATION
Northwest Energy Efficiency
Alliance (NEEA)
NEEA is a regional group whose mission is to
catalyze the Northwest marketplace to embrace
energy-efficient products and services.
IPC accomplishes market transformation in its
service area through membership and
coordinated activities with NEEA.
NEEA Activities
Industrial Efficiency Alliance (lEA)
Activities in Idaho
The IEA is a multi-year strategic effort designed
to improve energy efficiency in two regional
industries considered heavy-energy users-the
food processing and the pulp and paper
industries. The IEA also works with companies
that produce equipment and provide services for
these industries and with the utilities that serve
them.
Participants realize cost savings through the
adoption of energy-efficient business practices.
The IEA provides expert support, resources, and
services to give companies tools and training to
make energy efficiency a core business value. In
exchange, participants are asked to commit to a
Continuous Energy Improvement Program
which has the potential to increase production
capacity, improve equipment reliability, and
reduce operating costs and energy use by 5% to
20%. This effort is supported by providing
technical knowledge for individuals
organizations, and manufacturing companies to
collaborate on energy efficiency
implementation. IEA members include the BP A
regional utilities, the Energy Trust of Oregon
(ETO), ODOE, and the IED. Training activity in
2006 included a total of seven industrial
workshops co-sponsored by the IEA, IPC, and
others. This training activity focused on pumps
fans, compressed air, motors, and refrigeration.
Commercial Alliance Activities in Idaho
In Idaho, NEEA increased support of the Boise
Integrated Design Lab and BetterBricksCID
trainings and workshops, including the
sponsorship of the Third Annual BetterBricksCID
Awards. The IPC Building Efficiency program
was strategically designed to leverage the
BetterBricksCID and Boise Integrated Design Lab
offerings.
Residential NEEA Activities in Idaho
NEEA has two primary programs in the
residential sector-ENERGY STAR
(jj)
Homes
Northwest and Consumer Products. IPC was
one of the leading regional partners in the
ENERGY STARCID Homes Northwest program
providing 439 of2 335 homes, or 19% of all
homes certified in the region in 2006. IPC was
also a partner with NEEA in the SWAT
program.
Other NEEA Activities in Idaho
In 2006, NEEA conducted a new homes
construction survey to monitor the building
characteristics of new residential buildings in
the region. IPC paid for an additional
over-sample in the Treasure Valley in order to
obtain statistically valid data for energy
efficiency features of new homes in this area.
Information from both the regional study and
the specific Treasure Valley study will be used
in 2007 to develop new residential programs
and refine existing residential programs, such as
ENERGY STARCID Homes Northwest.
NEEA continued to provide energy code
support to jurisdictions in Idaho in the form of
funding for code training and other activities.
This funding also supported the efforts of the
Idaho Building Code Coalition, which met
frequently in 2006 to develop a bipartisan
document that will be presented to the Idaho
legislature during its 2007 session as it evaluates
adopting the 2006 International Energy Code.
Annual Report 2006 Page 43
Demand-Side Management Idaho Power Company
Each year NEEA underwrites the Idaho Energy
Conference through a contract with the
Association of Idaho Cities. NEEA continues to
provide general information support to the
region by funding the Energyldeas
ClearinghouseCID and ConWebCID
NEEA Funding
In 2005 , IPC began the first year of the
2005-2009 contract and funding agreement with
NEEA. Per this agreement, IPC committed to
fund $1 300 000 annually in support ofNEEA'
implementation of Market Transformation
programs in its service area. Of this amount
75% is funded through the Idaho and Oregon
Riders, and 25% is funded by a credit
accumulated during the previous contract
period.
In 2006, IPC paid $918 495 to NEEA. The
Idaho jurisdictional share of the payments was
$872 570, while $45 925 was paid for the
Oregon jurisdiction. Other expenses associated
with NEEA activities, such as administration
and travel, are paid by IPc.
Preliminary estimates reported by NEEA
indicate that IPC' s share of regional market
transformation MWh savings for 2006 is
337 MWh or 2.5 aMW. IPC relies on NEEA
to report the energy savings and other benefits
of NEE A's regional portfolio of initiatives.

ENERGY EFFICIENCY
ADVISORY GROUP (EEAG)
The EEAG, formed in May 2002, provides input
on formulating and implementing energy
efficiency and demand reduction programs that
are funded by the Rider. The EEAG currently
consists of 12 members from across IPC'
service area and the Northwest. Members
represent a cross-section of customers, including
representatives from the residential, industrial
commercial, and irrigation sectors, as well as
elderly, low income, and environmental
organizations, state agencies, the public utility
commissions, and representatives from IPC.
In 2006, the EEAG met three times: on
February 2, July 13, and November 16. In the
meetings, IPC provided a status of the Rider
funding and expenses, provided updates on
ongoing programs and projects, requested
recommendations on new program proposals
and provided information to the group on DSM
Issues.
EEAG Program
Recommendations
The following section provides a review of the
input provided to IPC by the EEAG regarding
major program implementation and operational
issues in 2006. Please note that all operational
DSM programs have been reviewed by EEAG;
however, only substantial changes or
modifications associated with EEAG input are
presented below.
Residential Programs
Residential programs reviewed in 2006 include
ENERGY STARCID Homes Northwest AlC Cool
Credit, SW AT, and the Residential Energy
Efficiency Education Initiative. In addition, the
group was given the opportunity to review plans
for new residential cooling and lighting
programs to be implemented in 2007.
Comments from the EEAG on these programs
included the following:
Group members suggested using existing
delivery mechanisms-The homes usually
are larger and have out-of-state owners, so
cost and peak demand may not be issues;
Stay way from the fixtures and go with
bulbs-Fixtures have non-standardized pins
and cost about $50, compared to $2 for the
same cost savings;
Look at a touchier replacement program;
Make purchasing the bulb an easy
transaction;
Do not over-target the product as in
prevIOus years;
Market only to available supply;
Train and commission installers,
homeowners, and employees to ensure
systems are operating at expected levels.
Commercial and
Industrial Programs
IPC presented updates to the EEAG during the
July and November meetings and received input
regarding new programs targeted to the
commercial and industrial sectors. These
2007 programs will integrate existing
commercial and industrial offerings with new
programs to provide a full array of incentives
and services for energy efficiency and demand
reduction at customer facilities. Ideas and
feedback centered on modifications that would
increase participation and streamline and reduce
the complexity of programs. Members provided
the following suggestions:
Annual Report 2006 Page 45
Demand~Side Management
Incentive caps:
Raise the cap and make it a "soft" cap.
Look at other programs to decide what the
limit will be.
Application procedures:
Penalize (with afee) ifno pre-application is
submitted and simplify small project
applications (below $500 or $1 000);
Encourage completion of pre-applications
or "intent to apply " for larger projects. This
way, staff can then encourage additional
projects. If there is no pre-application form
be careful of what qualifies. The program
must be very well marketed and understood.
The final ~esign for the new Easy Upgrades
program incorporated many of the above
suggestions, in addition to attributes associated
with input from commercial and industrial
customers. The Easy Upgrades program will
capture an additional portion of the commercial
customer population not served under existing
programs. The program will offer incentives
based on a $.12 per kWh savings, follow a
menu-option format, and be designed to cover
common retrofits. The payment cap is $100 000.
Partnerships with dealers will be made to
promote and market to customers.
IPC also asked for EEAG input as it considered
consolidating the services offered under the
existing Oregon School Efficiency program
with the Easy Upgrades program. This change
was proposed to reduce program overlap;
however, the Oregon Business Energy Tax
credit will still be available to customers in this
class. Modifications to the incentives include an
increase from $20 000 to $100 000 in the
incentive cap. Menu changes due to modified
regulation standards and technological growth
were also discussed. The new application
process will require applicants to submit an
expression of interest.
Idaho Power Company
Group Ideas and Feedback
Members would like the Oregon Business
Energy Tax credit to still be available;
Determine if there is a way to include
qualified net metering customers in the
commercial program.
Proposed changes to the Industrial Efficiency
Program were presented to the group. Under the
proposed changes, the upper incentive cap limit
would be changed from 50% to 70% of the
project cost. As a result of previous EEAG
discussions, all other incentive caps would be
eliminated. The program availability would be
expanded to include all commercial and
industrial customers. As a result, the name
would be changed to Custom Efficiency and a
minimum project size requirement of
000 kWh would be instituted.
Group Ideas and Feedback
Number of projects will increase with no
cap;
Business owners will be happier and more
willing to participate.
Irrigation Programs
The Irrigation Peak Rewards program has been
a successful program with visible megawatt
reductions in load observable at the system load
data level at 4:00 p.m. on scheduled summer
weekdays. In 2006, proposed program changes
were considered to improve customer
satisfaction and participation. These changes
included proposals to allow 75 hp pumps (a
change from the existing 100 hp minimum),
modification of the number of participation
days, and an increase in the participant demand
credit allowed. Incentive increases were also
proposed as a method for increasing program
participation rates. Such a change would also
Page 46 Annual Report 2006
Idaho'Power Company Demand-Side Management
allow for the elimination of the customer
demand charge for the participants in the
three-day per week service interruption option.
Discussions included moving the interruption
time from 3 p.m. to 7 p.; however, subsequent
input from customers indicated a desire for the
period to remain at 4 p.m. to 8 p.
The EEAG generally supported IPC's proposed
changes and offered the following ideas and
comments:
Take changes to Idaho and Oregon
commissions in late August;
Change wording from "penalty " to "fee.
s a cost issue not a punitive issue;
Cautioned that an additional set-up fee may
be a barrier to gaining program
participants;
Look at all program costs carefully. Do not
let incentive values offset actual costs;
Differentiate total costs between utility cost
and total resource costs.

OTHER PROGRAMS AND
ACTIVITIES
Residential
Education Initiative
IPC recognizes the value of general energy
efficiency awareness and education in creating
customer demand for, and satisfaction with, its
programs. Improvements in customer awareness
of IPC' s residential programs are being
achieved through the Residential Education
Initiative.
Activities
During the summer of 2006, research was
conducted in order to compile the industry
best energy efficiency practices, initiatives, and
activities. In addition to this research, four
customer focus group sessions were conducted
to query IPC's field and customer service
personnel in order to provide insight into
customer information needs in the area of
energy efficiency.
These efforts provided the basis for the
development of an educational plan for
residential customers to improve awareness of
the methods and benefits of IPC programs in
energy efficiency, demand response, and
renewable energy resources. The plan developed
outlines a program for customer education under
six specific goals for meeting educational needs.
The Residential Education Initiative will
complement and support existing programs in
the residential sector. IPC's new residential
DSM programs planned for implementation in
2007 will reflect these goals and objectives.
Distribution
Efficiency Initiative
Substation Pilot
Demonstration Project
NEEA is conducting a Pilot Demonstration
project with 10 Northwest utilities, both public
and private, to determine efficient ways to
design and operate distribution feeders. The
goal is to achieve energy savings by limiting the
primary distribution system voltage drop to
4 Volts (V) from 5V and operate the feeder
voltage in the lower bandwidth of the acceptable
voltage range, which is 126V to 114V, as
measured at the customer s meter. In addition
the use of line-drop compensation settings in the
substation voltage regulators will help reduce
the average feeder voltage during off-peak
periods. The study anticipates that the average
system voltage can be reduced by 3-5%, and the
expected energy savings associated with this
reduced voltage will be from 1-3% on average.
The pilot demonstration study will help
determine the energy savings on the utility side
of the meter and the energy savings for the
customers.
.. .-
The substation pilot demonstration project was
initiated at the Boise Substation in July 2006.
Three transformers and nine feeders have been
operating with a reduced voltage since that time.
The customer voltage was reduced by 3., on
average, which resulted in an estimated annual
energy savings of 4 050 MWh, or 3.5%.
Load Research Project
NEEA is conducting a residential load survey
project to determine the relationship between
the utility service voltage and the demand and
energy consumed by residential customers. The
study will ultimately place a Home Voltage
Regulator (HVR) at 500 locations across
10 Northwest utilities, both public and private.
The purpose of the HVR is to adjust
service-entrance voltage at the residence. A
Annual Report 2006 Page 49
Demand-Side Management Idaho Power Company
recording meter will then document the voltage
demand, and energy usage. The HVR will
operate at normal utility voltage for 24 hours
and then switch to regulate the service-entrance
voltage to 115V for the next 24 hours, toggling
day-on and day-off for a one-year period. The
voltage and energy relationship will then be
compared between the control days and the
non-control days to determine the change in
service-entrance voltage and demand and
energy usage at the residence. An in-home
survey will be conducted to determine end-use
load types, such as electric heating, air
conditioning cooling, type of lights, and other
energy-related information. A sample design
was developed by a private consulting firm to
evaluate the sample size and strata and
determine if different end-use load types had a
unique energy-to-voltage relationship.
Sixty-six HVRs have been operating in southern
Idaho since March 2006. These units have been
operating without failure during the year. The
customer voltage was reduced by 3.9% on
average , which resulted in an annual energy
savings of 361 kWh per household, or 2.3%.
Plan for 2007
A new pilot will be implemented during the first
quarter of 2007 to demonstrate remote
end-of- feeder control of the station transformer
load tap changer. This demonstration project
uses wireless communication between the
end-of- feeder and the substation. This
technology application will allow better control
of the end-of- feeder voltage.
The HVR program will be complete at the end
of the first quarter of 2007, and the devices will
be removed during the second quarter.
Small Project/Education Fund
The purpose of the Small Project/Education
Fund is to provide modest funding for
short-term projects and activities that do not fit
within other categories of energy efficiency
programs but still provide a defined benefit to
furthering DSM targets. In 2006, two projects
met these criteria.
Building Design Software
When the Integrated Design Lab in Boise was
planning to offer a special training class on
Energy Scheming in June 2006, they submitted
an application request for funds to provide free
software to 10 attendees (architects and
designers) at the class. Total actual cost of this
initiative was $2 120 and the estimated energy
savings was 4 000 000 kWh per year, based on
each recipient designing an average of
one million square feet of commercial space
over a software design life of 10 years. It was
determined that this funding was very cost
effective at an estimated $.00053 per kWh for
IPC. In addition, the software and the associated
training will support the goals of the Building
Efficiency program for commercial
construction.
CFL Education and Distribution
In February 2006, IPC was presented with an
invitation from Fort Hall tribal leaders for IPC
to participate in the Fort Hall Reservation
Idaho Energy Fair. IPC's participation was
focused on energy-efficient CFL lighting
penetration into local areas where retail
distribution opportunities were less developed.
A total of 480 bulbs and lighting efficiency tip
cards were distributed at a direct program cost
of $1 008 with an estimated energy savings of
027 kWh.

ApPENDICES
The following financial and performance tables
provide a summary of program activity,
including program expenses, funding sources
energy savings, and levelized costs for savings.
F or this 2006 DSM Annual Report, the
Historical Program Performance table is
reintroduced following its absence from the
2005 report. The table was excluded in 2005 to
allow reporting system conversion to a
standardized historical basis: A large part of the
alignment was associated with synchronizing
historical reporting practices, which included
reporting accrued energy savings associated
with incentive payments that had yet to be
reflected in the expense accounts (i., account
payable liabilities). In 2005, a decision was
made to report energy savings and expenses
based on a cash basis. This change ensures that
all energy savings are associated and reported
with the year in which the expense is recognized
and removes the necessity for reversing accruals
and restating the energy savings from
year-to-year in order to true-up historical
reporting.
The accounting method adopted was part of a
larger restructuring of the DSM reporting
system s architecture that occurred in 2006. The
system changes have provided the platform for
more productive reporting and analysis, in
addition to providing the basis for meeting
future demands from the significant growth in
program offerings and participation.
Changes to historical reporting are documented
in the footnotes to the historical program
performance report.
