AMENDED ORDER NO. 35480

On July 12, 2022, Intermountain Gas Company (“Company”), a subsidiary of MDU
Resources Group, Inc., filed an Application for an order designating $4,028,174 of 2021 Energy
Efficiency Program (“EE Program”) expenditures as prudently incurred. The Company has
submitted its 2021 Energy Efficiency Annual Report with the Application.
With this Order, the Commission provides notice of the Company’s Application and sets
a deadline for interested parties to intervene.
BACKGROUND
In 2017, the Commission authorized the Company to establish the EE Program for its
residential customers. See Case No. INT-G-16-02; Order No. 33757 at 35-37. The purpose of the
EE Program “is to encourage upgrades to, or use of, high efficiency natural gas equipment.” Rate
Schedule EE, Intermountain Gas Company I.P.U.C. Gas Tariff, Sheet No. 16 at 1. On July 27,
2017, the Company requested Commission authority to implement a funding mechanism for the
EE Program. See Case No. INT-G-17-03. The Commission approved the Company’s requested
funding mechanism of an Energy Efficiency Charge (“EEC”) for the EE Program, and approved
Rate Schedules EE, EEC, and RS. The Commission found that the proposed EEC to residential
customers of $0.00367 per therm to fund the EE Program was reasonable and appropriate. Order
No. 33888 at 3.
In Case No. INT-G-19-04, the Commission required the Company to commission a third-
party Evaluation, Measurement and Verification (“EM&V”) study, review and update the
avoided cost calculation with the Energy Efficiency Stakeholder Committee (“EESC”),
immediately and continuously monitor, evaluate, and update its EE Program incentives with the
best available data, and discontinue the 80% AFUE condensing fireplace incentive. Order

In Case No. INT-G-20-04, the Commission authorized the Company to implement a
Commercial EE Program in Rate Schedule EE-GS and established a funding mechanism for
program costs in Rate Schedule EEC-GS (“EEC-GS”), which set the EEC-GS at $0.00320 per
therm. The Commission directed the Company to develop an EM&V plan, file an Annual
Commercial EE Program Report, include representatives from the GS-l rate class in its EESC,
and immediately and continuously monitor, evaluate, and update its Commercial EE Program
incentives with the best available data. Order No. 34941.
In Case No. INT-G-21-03, the Commission acknowledged an overfunded rider balance
in the EE Program of $1,318,197 and permitted the Company to carry forward the balance to
meet anticipated increased EE Program participation. Order No. 35313 at 5.
