On June 28,2019,IdahoPower Company ("Company")filed an Application requesting
the Commission acknowledge the Company's 2019 Integrated Resource Plan ("IRP").The IRP is
the Company's biennial report on its plans to adequately and reliably serve its customers over the
next 20 years through a least-cost least-risk resource mix.
After the Company filed its 2019 IRP,it notified the Commission it would need to file
a supplemental analysis to confirm the findings of its IRP.The Company requested the
Commission not set a timeline by which to process this case until the Company had submitted its
amended 2019 IRP.
On August 13,2019,the Commission issued a Notice of Application stating the
Commission would issue a Notice establishing procedure and deadlines followingthe submittal of
the Company's amended 2019 IRP.Order No.34410.
On January 31,2020,the Company submitted its amended 2019 IRP.
The Commission now issues this Notice of Amended IRP and Notice of Intervention
Deadline.
NOTICE OF AMENDED IRP
YOU ARE HEREBY NOTIFIED that the Company used AURORA,a long-term
capacity expansion ("LTCE")model,to develop 12 portfolios based on three natural gas forecasts
and four possible carbon emission adders.The Company modeled these scenarios with the
Boardman to Hemingway transmission line project ("B2H")coming online in 2026 or not at all,

cost least-risk portfolios for Idaho Power's customers.

AURORA by developing 24 WECC-optimized portfolios and then manuallyadjusting the top-
performing portfolios to identifypotential least-cost least-risk portfolios for Idaho Power's service
territory.

revenues associated with B2H.
