NEWS RELEASE: Commission schedules online public workshops on transmission line project

BOISE – The Idaho Public Utilities Commission will host public workshops on April 17 and
April 19 to share information on applications from two electric utilities that have applied for
permits to build a 500-kilovolt transmission line.

Rocky Mountain Power and Idaho Power have applied for certificates of public convenience and
necessity as part of the process to build the Boardman-to-Hemingway transmission line, which
they will co-own. A certificate of public convenience and necessity is a permit granted to a
utility that allows it to provide service to a new geographic area, enter into a franchise
agreement, build and operate a new facility or build an extension of an existing facility. The
permit covers activities that are outside of a utility’s usual course of business.

Rocky Mountain Power said the transmission line is needed to create lower-cost and more
reliable electricity transmission service for its growing customer load and to avoid spending
more for higher-cost generation and transmission resources.

Idaho Power said population and business growth in the region are increasing demand for
electricity, and existing transmission lines can’t carry additional electricity when it is most
needed.

The workshop for Idaho Power’s application will be Monday, April 17. Staff with the public
utilities commission will present information on the application and answer questions. It will
start at 6:00 p.m. (MDT) and end at 9:00 p.m., or after questions from the public have been
answered, whichever comes first. To participate over the phone, please call 1-415-655-0001 and
enter meeting number 2454 319 4150 when prompted. Next, enter this numeric password:

The workshop for Rocky Mountain Power’s application will be Wednesday, April 19. Staff with
the commission will present information on the application and answer questions. It will start at
6:00 p.m. (MDT) and end at 9:00 p.m., or after all questions from the public have been
