SUPPLEMENT 1: 2021 COST-EFFECTIVENESS
2021
ANNUAL REPORT
Introduction
Intermountain’s Energy Efficiency Program (EE Program) offers individual customers a way to lower their
usage and monthly energy bills. It additionally benefits all customers by ensuring resources are used
efficiently which delays the need for expensive system upgrades and additional supply contracts,
thereby keeping costs low for everyone. Cost-effectiveness testing is vital to ensuring the Company’s EE
Program is in fact a least-cost resource, and is integral to the design, implementation, and success of the
EE Program.
Cost-Effectiveness and Methodology
Intermountain’s objective is for all rebates to have benefit/cost ratios greater than one for the Utility
Cost Test (UCT). The UCT measures cost-effectiveness from the utility company’s perspective and takes
into consideration avoided supply costs, program administration costs and incentives paid by the utility.
Rebates undergo cost tests at several stages: preliminary design, implementation, and an annual review.
For a different perspective, cost-effectiveness of rebates is also evaluated based on the customer’s
perspective using avoided supply costs, program administration costs and net participant costs, or the
Total Resource Cost Test (TRC). However, the TRC is not the primary cost test used for decisions
regarding the inclusion or exclusion of rebate offerings. In calculating the UCT and TRC, Intermountain
relies on the calculations outlined in the California Standard Practice Manual and the National Action
Plan for Energy Efficiency’s (NAPEE) Understanding Cost Effectiveness of Energy Efficiency Programs:
Best Practices, Technical Methods, and Emerging Issues for Policy-Makers.
Rebate characteristics such as estimated useful life, deemed therm savings, and incremental cost used
for cost-effectiveness testing are provided by the CPA study for all rebates, except for Whole Home
rebates. Estimated therm savings for Whole Home rebates are based on the EM&V impact evaluation.
The rebate count used in the cost-effectiveness calculation is the actual number of rebates paid for the
program year.
Cost-effectiveness of EE Program rebates are reviewed annually. The results are reported in the annual
report and reviewed with the Energy Efficiency Stakeholder Committee (EESC). Rebate performance,
cost-effectiveness, market insights, and lessons learned are taken into consideration when deciding
whether to continue, revise or retire a rebate.

1
Assumptions
In calculating cost-effectiveness for each rebate and for the Program as a whole, the Company relied
upon several assumptions as well as studies provided by independent third-party sources. The section
below discusses the key inputs used in calculating cost-effectiveness and the assumptions and sources
used.
Energy Savings
Energy savings for each rebate are calculated by multiplying each rebate’s gross annual therm savings by
the total number of rebates issued. The energy savings are then valuated based on the Company’s
Avoided Cost. The Avoided Cost is used both to economically evaluate the present value of the therms
saved over the life span of the measure and to track the performance of the EE Program. A more in-
depth discussion of the Avoided Cost calculation and its components can be found in Case No. INT-G-22-
03, Exhibit No. 1 which was originally filed as Exhibit No. 5 in Intermountain’s Integrated Resource Plan
(Case No. INT-G-21-06).
Rebate Costs
Total rebate costs are calculated by multiplying the value of each rebate by the number of rebates
issued for the year.
Equipment & Installation Cost
The incremental equipment and installation costs are inputs to the TRC cost test and were provided by
the CPA. These costs represent the incremental purchase and installation costs the participant will pay
between a base case measure and a higher efficient alternative. These costs are not offset by the
amount of the rebate received by the participant.
Program Delivery & Administration
Program delivery and administration costs are direct assigned to their respective program, either
residential or commercial, when they can be specifically identified. For example, the expense of a
residential builder mailing list is charged to Residential Program delivery and administration costs. After
all direct costs are assigned, the remaining pool of program and administration costs, are split between
the residential program and commercial program based on a respective 80/20 split. This ratio is based
on program uptake estimates from the 2019 CPA and is intended to divide costs considering the newly
2
formed commercial program. Within each program, expenses are allocated to each rebate based on the
rebate count as percentage of all rebates. This method ensures that costs are allocated in alignment
with the overall processing and payment work involved for that rebate. Any cost incurred solely for a
particular rebate will be directly assigned to that rebate.
Real Discount Rate
The real discount rate is used to account for the time-value of money and accurately compare costs. The
real discount rate is based on the Company’s tax-affected weighted average cost of capital. The
calculation of the real discount rate can be found in Case No. INT-G-22-03, Exhibit No. 1, Page 11.
Inflation Rate
An inflation assumption is used in cost-effectiveness testing to convert nominal, forward-looking costs
into real dollars. The company assumes an inflation rate of 2.0%.
Net-to-Gross
Net-to-gross (NTG) is a ratio that adjusts the therm savings of rebates and/or programs, so they solely
reflect energy efficiency gains that are the direct result of energy efficiency programs. The NTG deducts
therm savings resulting from free-ridership, or savings that would have occurred regardless of the
program. It also increases therm savings to account for spillover, or savings that occurred but were not
counted by the program, as well as therm savings resulting from market transformation. Unfortunately,
estimates of net savings require making sweeping assumptions to model a theoretical scenario where
the EE Program did not exist. Because of the difficulty in accurately calculating NTG percentages, the
Company used an NTG of 100% for all rebate and program cost-effectiveness analysis. Intermountain
also performs a sensitivity analysis for each rebate that determines the minimum allowable NTG ratio
where the rebate would remain (or become) cost effective under the Utility Cost Test.
Results
The Company performed cost-effectiveness testing at the program level and the individual measure
level. The Residential Program was found to be cost-effective with a UCT of 1.5. The Commercial
Program remains in an awareness-building mode since its launch on April 1, 2021. The UCT of the
Commercial Program was 0.4.

3
EM&V Schedule
The Company prepared a revised EM&V schedule through 2024. The dates on the schedule indicate the
final year of data that will be included in the study. For example, the initial study that was conducted in
2020 used data through the year ended 2019.
The schedule was amended based on the amount of data available for analysis. The impact evaluation
for residential water heating measures was moved to year end 2023 due to the limited number of both
storage and tankless water heater rebates. The Company updated both the storage and water heater
rebates effective April 1, 2021, and uptake has already increased. The impact evaluation planned for
year-end 2022 for commercial kitchen rebates, fryer, griddle, and steamer, was also postponed. Due to
the slow uptake in the Commercial Program, the Company plans to conduct a process evaluation for all
commercial measures for year-end 2023. The Company consulted with the EESC on the revised EM&V
study timing. In the interim years between formal, third-party evaluation, the Company will monitor,
evaluate, and update program incentives with the best data available.
