Rocky Mountain Power seeks approval for sales agreement
with 481-kilowatt Preston area hydroelectric facility

BOISE (October 6, 2015) – PacifiCorp, which operates as Rocky Mountain Power in eastern
Idaho, is asking state regulators to approve a sales agreement between it and a Preston area
hydroelectric facility.

The 481-kilowatt hydro project, owned by Consolidated Irrigation Company, is a qualifying
facility under the provisions of the Public Utility Regulatory Policies Act. PURPA requires utilities
to buy output from qualifying renewable projects at an “avoided-cost rate,” or the rate the
utility avoids by not having to generate the power itself or buy it from another source.

The contract, if approved by the Idaho Public Utilities Commission, is for 20 years. The
commission’s published avoided-cost rate for non-intermittent projects smaller than 1
megawatt with contracts signed in 2015 is $59.88 per megawatt-hour. The proposed contract is
for a non-levelized rate, which means the price paid the project increases gradually through the
20-year life of the contract to $103.05 per MWh in 2034.
