Attorneys for Idaho Power Company
BEFORE THE IDAHO PUBLIC UTILITIES COMMISSION
IN THE MATTER OF IDAHO POWER )
COMPANY'S APPLICATION FOR ) CASE NO. IPC-E-25-09
MODIFICATIONS TO THE COMPANY'S )
RESIDENTIAL DEMAND RESPONSE ) APPLICATION
PROGRAM, SCHEDULE 81 )
Idaho Power Company ("Idaho Power" or "Company"), pursuant to Idaho Code §§
61-502, -503, and -507, and Idaho Public Utilities Commission's ("Commission") Rule of
Procedure ("RP") 52, submits its Application requesting modifications to the Company's
Schedule 81, Residential Air Conditioner Cycling Program, ("Schedule 81"). The Air
Conditioning Cool Credit ("ACCC") program is the Company's residential demand
response ("DR") program, which is relied upon to reduce summer electricity demand
during times of system need. Currently, customers have one option to participate in the
ACCC program, the Air Conditioner ("AC") Cycling option, which allows Idaho Power to
connect a load control device to a customer's AC unit to cycle the AC unit during DR
events. As more fully set forth below in this Application, and in response to an Integrated
Resource Plan ("IRP") identified need and non-participant feedback, Idaho Power
APPLICATION - 1

proposes to add a Bring Your Own Thermostat ("BYOT") option to the ACCC program.
Idaho Power is pursuing the BYOT option as an additional DR offering to expand its
residential ACCC program participation levels. In support of this Application, Idaho Power
represents as follows:
I. BACKGROUND
1. Purpose of DR. To minimize or delay the need for new supply-side
resources, the Company's DR programs are designed to be available to meet potential
system capacity deficits during high-risk time periods that typically occur during low hydro
generation and high load events on Idaho Power's system. Because the deficits are
expected to be relatively large in magnitude but short in duration, it can be cost-effective
to utilize DR programs rather than acquiring a supply-side resource that would only be
necessary for a small number of hours.
2. DR Programs Offered. Idaho Power's DR portfolio currently has three
optional programs with one available to each of the three major customer segments
including the irrigation Peak Rewards Program (Schedule 23), the commercial and
industrial Flex Peak Program (Schedule 82), and the residential ACCC program.
3. 2024 ACCC Season Performance. The ACCC program is offered to
customers in the Company's service area who take service under Schedule 1, Residential
Service; Schedule 5, Residential Service Time-of-Use Plan; and Schedule 6, Residential
Service On-Site Generation. Customers can currently participate by having a device
installed on their AC unit that automatically cycles the unit' when the Company calls a DR
event. At the start of the 2024 DR season, 17,753 participating service points were
' Cycling refers to switching the AC unit on and off in intervals over the event period. Intervals for cycling
(or% cycling) are set with the intent to balance the system needs with participant comfort.
APPLICATION - 2

enrolled in ACCC with approximately 24 megawatts ("MW") of capacity. ACCC's results
are evaluated and reported annually in Supplement 2 of the Demand-Side Management
("DSM") Annual Report. The report contains load reduction performance by event,
realization rates, participant counts, etc. During the 2024 season, the Company called 5
ACCC DR events with an estimated actual maximum load reduction of 21.9 MW. The full
2024 season results will be published March 14, 2025, when the Company files its 2024
DSM Annual Report.
4. 2023 IRP DR Potential Study. As part of the 2023 IRP's examination of the
potential for expanded DR, Idaho Power contracted with a third-party evaluator to provide
a 20-year forecast of Idaho Power's DR program potential to estimate what may be
available in Idaho Power's service area. Based on this study, Idaho Power grouped
expansion of its current programs and other potential programs into similar price and
characteristic buckets for analysis within the AURORA model. The analysis selected an
additional 20 MW of DR capacity in the IRP's preferred portfolio for 2029. Based on this
analysis and considering the results of the study that identified a BYOT option as one of
the lower cost DR programs beyond current program expansion that the Company may
be able to offer, Idaho Power issued a request for proposal ("RFP") to potential BYOT
vendors. Using results from the RFP, the Company determined the BYOT option could
be a cost-effective addition to its current ACCC program.
5. The Company is continually evaluating opportunities and identifying ways
to improve DR programs and actively works to improve its DR offerings. To this end, the
Company is proposing to add a BYOT option to its ACCC program, which would be
APPLICATION - 3

offered in addition to the AC Cycling option described above.
6. As more fully explained below, the Company's proposed modifications are
intended to increase participation in the Company's ACCC program by offering customers
another option and to help advance the DR program potential identified through the IRP
process. Included as Attachment 1 to this Application are clean and legislative versions
of proposed Schedule 81 that are intended to implement the changes being proposed by
the Company, which it believes will help ensure the continued success of cost-effective
programs that are relied upon to meet system needs.
II. BYOT OPTION
7. Under the BYOT option, smart thermostats, installed in customers' homes,
would be used to reduce demand when a DR event is called by automatically adjusting
the temperature settings. Customers must have a qualified smart thermostat to participate
in the offering. A list of Company approved qualified smart thermostats will be maintained
on the Company's website.
8. The Company will partner with a third-party aggregator ("aggregator") who
will coordinate directly with the smart thermostat original equipment manufacturers
("OEM")to facilitate the BYOT offering. The aggregator will provide a centralized interface
that the Company can use to communicate with all major thermostat brands. The
aggregator will also support the customer enrollment process, help optimize thermostat
responses, and assist in post-event reporting.
9. OEMs will market the program to qualified customers across various
channels engaging consumers through their computer, tablet or cellphone applications
(or "apps"). Most OEMs will leverage email marketing campaigns, sending emails to
APPLICATION -4

qualified customers at least once a year or once per DR season and often more
frequently, some on a quarterly basis. Although a few manufacturers no longer support
email marketing, all OEMs utilize in-app marketing. When an eligible customer registers
a qualified thermostat, marketing material will be displayed on their app. Additionally, the
OEMs will display periodic marketing pop ups and marketing information within the app
menu for eligible customers.
10. Additionally, the Company plans to market to customers that have received
a smart thermostat incentive offered under the Heating and Cooling Efficiency Program.2
The Company will also target marketing to customers who are not AC Cycling
participants, and it anticipates marketing in tandem with its smart thermostat incentive
offered under the Heating and Cooling Efficiency Program.
11. Idaho Power will define the necessary customer data for verifying eligibility,
which each OEM will collect when the customer enrolls. The aggregator will develop co-
branded enrollment portals for participating OEMs. During enrollment, customers will
accept terms and conditions from Idaho Power, the aggregator, and OEMs.
12. The aggregator will send the signal to the smart thermostats when a DR
event is called by the Company. Similar to the AC Cycling option, BYOT option
participants will not receive prior notice when an event is called. However, at the time of
the event BYOT participants will receive notification through their smart thermostat's app
that an event has started, and the smart thermostat will indicate when they are in an
event.
2 The Heating and Cooling Efficiency Program provides customers with energy-efficient options for space
heating/cooling and water heating. The program provides incentives to residential customers, builders,
landlords, and installation contractors for the purchase and proper installation of qualified heating and
cooling equipment and services.
APPLICATION - 5

13. Idaho Power will collaborate with the aggregator to establish its DR
objectives. The aggregator's data science team will configure the Demand Response
Management System to effectively meet the Company's goals using the available data
inputs. This process involves analyzing each home's thermodynamic properties, weather
forecasts, and customer preferences to achieve the Company's DR targets. Control
strategies will include pre-cooling,3 thermostat setbacks,4 and cycling levels.5 The
aggregator will work with the Company on an ongoing basis to ensure that the Company's
load management objectives are consistently met throughout the BYOT option.
14. Under the Company's proposal, new ACCC participants who enroll in the
BYOT option will receive a $50 enrollment incentive. The enrollment incentive includes
the first year of participation incentives. Customers who leave the BYOT option and later
re-enroll in BYOT are not eligible for an additional enrollment incentive, nor are customers
who leave the AC Cycling option within 12 months of applying to participate in the BYOT
option. After being enrolled for 12 full months, participating customers will be eligible to
begin receiving $5 bill credits for the months of June, July, August, and September, for a
maximum annual incentive of $20, which is the same incentive that customers
participating in the AC Cycling option receive. Customers with partial month participation
will have their participation prorated. To be eligible for the bill credits, a BYOT participant
must participate in at least 50 percent of DR event hours during the DR season.
15. Based on feedback from other peer utilities who have offerings similar to
the BYOT option and from third-party vendors of similar offerings, the Company does not

APPLICATION - 6

anticipate customers signing up for the BYOT option to get the enrollment incentive and
then leaving the program. Peer utilities and vendors have expressed that they do not often
see this in practice.
16. The Company acknowledges that there may be some customers in the AC
Cycling option that choose to transition to the BYOT option. In part to help mitigate
migration from one option to the other, the Company has set the annual incentive the
same for both options.
17. The Company is proposing the BYOT option as an additional element of its
existing ACCC program as it may be more enticing to some customers. In the past few
years, the Company has seen attrition in its AC Cycling option despite continued
marketing efforts, enrollment contests, and a 2024 promotion offering an enrollment
incentive to customers that had an inactive device installed at their residence and began
participating in the program. The Company is confident that the BYOT option will
ultimately be cost-effective and increase the available capacity of its DR portfolio, helping
to offset some of the attrition from the AC Cycling option. Additionally, the Company plans
to monitor the results of the initial three-year BYOT contract and report on it in its annual
DSM report. The Company will use these results to determine how to proceed at the end
of the three years.
III. COST-EFFECTIVENESS & STAKEHOLDER INPUT
18. Cost-Effectiveness BYOT Option. As with most DR programs, it is
anticipated that there will be higher upfront costs (primarily made up of the enrollment
incentives and the initial aggregator fee) as well as low capacity in the offering's initial
years and as a result the BYOT option proposed in this Application is not anticipated to
APPLICATION - 7

be cost-effective on a measure level until year three and after. This is based on the
assumption of 6,500 new participants in year one, 13,000 in years two and three, and
4,000 in all years after. The Company anticipates the cost per kilowatt ("kW") for the first
three years to be $107.26, $67.05, and $55.59, respectively. Only year three is
anticipated to be under the 2025 avoided cost threshold of$64.03 per kW, which is based
on the 2023 IRP. Based on current assumptions and costs, the Company anticipates the
BYOT option to remain cost effective after the initial three years.
19. Cost-Effectiveness BYOT Option (With Cost Spreading). In its cost-
effectiveness modeling for the option, the Company performed an analysis, spreading the
initial aggregator fee over the initial three years and the enrollment incentives over three
years from when they are paid to customers. When these costs are spread using the
method described above, the annual cost per kW for the first three years are $54.69,
$49.29, and $52.81, respectively. Each of these annual cost amounts are under the 2025
avoided cost threshold of $64.03 per kW. The annual cost per kW for years four and five
are $55.85 and $52.29, respectively, also under the 2025 avoided cost threshold. See
Chart 1 for a comparison between anticipated annual costs of the program, the costs of
the program when spreading the enrollment incentives and initial start-up costs, and the
2025 avoided cost threshold.

20. The Company believes evaluating cost-effectiveness in this manner for a
new program option with one-time upfront costs provides a more complete analysis of the
program value when using the existing cost-effectiveness framework, which was
designed for the purpose of analyzing a single year of a mature program, and not a
multiple-year contract of a new program. The Company has included its cost-
effectiveness workpapers in Attachment 2 to this Application.6
6 Because Attachment 2 includes confidential information that Idaho Power and/or a third-party claim
constitutes trade secrets or other confidential business data exempt from disclosure, the Company has
included a redacted version of the attachment with this filing. An unredacted, confidential version of the
workpapers in native format will be filed separately and available to parties who sign the Protective
Agreement.
APPLICATION - 9

21. Cost Effectiveness Total ACCC Program. The ACCC program with the
addition of the BYOT option is anticipated to be cost-effective in all years. The Company
used actual annual costs for the BYOT option in its analysis of the cost-effectiveness of
the ACCC program. For the initial three years the annual cost per kW are $58.09, $56.07,
$52.58, respectively. Each of these annual cost amounts are under the 2025 avoided cost
threshold of $64.03 per kW. See Chart 2 for anticipated program cost-effectiveness over
the next five years.

22. Based on current assumptions and costs, the Company anticipates the
ACCC program will remain cost effective during the initial three years with the inclusion
of the BYOT option.
23. Cost Effectiveness Reporting. The Company plans to report cost-
effectiveness in its Annual DSM Report at the ACCC program level. Additionally, the
APPLICATION - 10

Company intends to provide cost-effectiveness information for both the AC Cycling and
BYOT options using actual year costs.
24. Stakeholder Engagement. The Company presented details of the BYOT
option at the November 14, 2024, Energy Efficiency Advisory Group ("EEAG") meeting.
The Company explained the logistics, potential participation and capacity, and the cost-
effectiveness of the option. EEAG members asked several clarifying questions, including
how the two DR options would interact, whether there were synergies between the
proposed BYOT DR option and the existing smart thermostat incentive offered under the
Heating and Cooling Energy Efficiency program, how the program offering would be
marketed, as well as questions about the assumptions for the cost-effectiveness analysis.
Generally, EEAG members were supportive of the Company pursuing the BYOT option,
with specific support stated for the diversification the BYOT option would add to the ACCC
program.
25. Additionally, the Company met with Commission Staff ("Staff") on January
29, 2025, to further discuss the BYOT option. The Company and Staff discussed the
structure and incentives for the BYOT option, how BYOT will be marketed, how the
Company is mitigating the risk of customers moving from the AC Cycling option to the
BYOT option, the risk of customers enrolling in BYOT for the enrollment incentive to then
drop out, the cost-effectiveness of the option, and the Company's plans after the initial
three years of BYOT. Based on the discussion with Staff, the Company has included
additional information in this Application to address risk mitigation and the Company's
plans for determining how to proceed after the initial three-year period.
