INTERVENTION DEADLINE

ORDER NO. 35678

On January 27, 2023, Rocky Mountain Power, a division of PacifiCorp (“Company”) filed
an application (“Application”) requesting an order granting a Certificate of Public Convenience
and Necessity (“CPCN”) for Energy Gateway Segment H, the Boardman-to-Hemingway 500-
kilovolt (“kV”) transmission line (“B2H” or “Project”). The Company represents that it will co-
own B2H with Idaho Power Company (“IPC”), which recently filed its own CPCN application for
the Project in Case No. IPC-E-23-01.
The Company represents that B2H is an approximately 300-mile-long, 500-kV electric
transmission line that will extend from a switching station constructed near Boardman, Oregon to
the existing Hemingway Substation located in Owyhee County, Idaho. the Company states that
approximately two hundred and seventy-four (274) miles of the transmission line will be in five
Oregon counties: Malheur, Baker, Union, Umatilla, and Morrow Counties, and a 24-mile segment
of the Project will be in Owyhee County in Idaho. The Company represents that B2H will also
include ten communication stations along the route that are constructed within the right-of way of
the transmission line, and B2H will also include the installation of the B2H Midline Series
Capacitor Project and development of a remedial action scheme.
NOTICE OF APPLICATION
YOU ARE HEREBY NOTIFIED that the Company represents that B2H enables lower-
cost and more reliable transmission service to serve customer load and increases transmission
connectivity between PacifiCorp East (“PACE”) and PacifiCorp West (“PACW”) and will enable
the Company to cost-effectively and reliably serve growing customer load. The Company states
that these benefits primarily result from cost savings in serving load in central Oregon and near
the proposed Longhorn substation. Application at 9.

ORDER NO. 35678 2
YOU ARE FURTHER NOTIFIED that the Company represents that B2H is the most cost-
effective means of serving the Company’s load, and that without B2H, the Company would be
required to acquire higher-cost generation resources and third-party transmission service, which
together would increase customer costs by approximately $1.713 billion through 2042. Id.
YOU ARE FURTHER NOTIFIED that the Company represents that the cost savings are
all based on an anticipated 2026 in-service date for B2H. The Company states that to ensure that
the Project can be energized in time for a 2026 in-service date, construction must begin in the
summer of 2023. The Company requests that the Commission issue an order on its Application no
later than June 30, 2023. Id. at 9-10.
YOU ARE FURTHER NOTIFIED that the Application and supporting documentation
have been filed with the Commission and are available for public inspection during regular
business hours at the Commission’s office. These documents are also available on the
