PUC accepts PacifiCorp agreement to buy
generation from BYU-I cogeneration plant

BOISE (June 16, 2015) – The Idaho Public Utilities Commission has approved a two-year power
purchase agreement between PacifiCorp and Brigham Young University-Idaho.

Under the agreement, BYU-I will sell the output of its gas- and oil-fueled generating facility on
its Rexburg campus to PacifiCorp, which does business as Rocky Mountain Power in eastern
Idaho. The plant provides space and water heating to the campus, but also has a companion
heat-recovery generating system that can generate up to 5.6 megawatts of electricity.

The power purchase agreement falls under the provisions of the Public Utility Regulatory
Policies Act of 1978. PURPA requires regulated utilities to buy energy from qualifying
renewable generation projects at rates established by state commissions. The rate to be paid
qualifying projects is called an “avoided-cost rate,” because it is based on the cost the utility
avoids by not having to generate the energy itself or buy it from another source. The
commission must ensure the avoided-cost rate is reasonable because the price utilities pay to
independent electric generators is passed on to customers. While PURPA requires utilities to
buy from independent projects, the law leaves it up to states to determine avoided-cost rates
and other contract terms and conditions.

The average annual rate PacifiCorp will pay BYU-I is $52.28 per megawatt-hour for sales during
2015, $51.84 per MWh in 2016 and $55.01 per MWh in 2017. The rate can be adjusted slightly
for electricity delivery during on-peak and off-peak hours.
