On March 5, 2026, the Idaho Public Utilities Commission ("Commission") issued Order
No. 36956, conditionally approving the energy sales agreement ("ESA") between Idaho Power
Company ("Company") and Fossil Gulch Wind Park, LLC ("Seller") for energy generated by the
Fossil Gulch Wind Park in Twin Falls County, Idaho. The order required the Company and the
Seller to execute several modifications to the ESA and file an updated ESA through a compliance
filing. Order No. 36956 at 5.
On May 4,2026,the Company filed the First Amendment to the ESA through a compliance
filing to reflect the modifications required by Order No. 36956.
The Commission now issues this Order approving the Company's compliance filing
submitted on May 4, 2026.
COMMISSION FINDINGS AND DECISION
The Commission has jurisdiction over this matter under Idaho Code §§ 61-502 and 61-
503. The Commission is empowered to investigate rates, charges,rules,regulations,practices,and
contracts of public utilities and to determine whether they are just, reasonable, preferential,
discriminatory,or in violation of any provision of law,and to fix the same by order.Idaho Code §§
61-502 and 61-503.
Having reviewed the Company's compliance filing and Staff s recommendation, we
approve the First Amendment to the ESA included in the Company's compliance filing of May 4,
2026. According to Staff, the First Amendment to the ESA reflects all Commission-ordered
modifications, except for calculating avoided cost rates based on the updated hourly generation
profile. Staff stated that the specified generation profile was not available at an hourly level, so
"the parties re-calculated the avoided cost rates based on a new 8760-hour generation profile
ORDER NO. 37071 1

produced after Order No. 36956 was issued." Staff Decision Memorandum at 2. Given the
unavailability of the generation profile that the Commission directed the parties to use, we agree
with the parties that using the new hourly generation profile to re-calculate the avoided cost rate
was a reasonable alternative.Id.
ORDER
IT IS HEREBY ORDERED that the First Amendment to the ESA included in the
Company's compliance filing of May 4, 2026, is approved.
THIS IS A FINAL ORDER. Any person interested in this Order may petition for
reconsideration within 21 days of the service date upon this Order regarding any matter decided in
this Order. Within seven days after any person has petitioned for reconsideration, any other person
may cross-petition for reconsideration.Idaho Code §§ 61-626.
DONE by order of the Idaho Public Utilities Commission at Boise, Idaho this 16t" day of
