Re:CASE NO. PAC.E.18-02:

UPDATED NATURAL GAS PRICE FORECAST OF THE U.S. ENERGY
INFORMATION ADMINISTRATION (EIA)
Dear Mr. Costello;
Thank you for your letter and worksheets dated April 5,2018, with PacifiCorp's updated Surrogate
Avoided Resource ("SAR") rates. Pursuant to OrderNo. 32697, the final release ofthe U.S. Energy
Information Administration's (EIA's) Annual Energy Outlook automatically triggers an update to
the published avoided cost rates under the SAR methodology. EIA issued their Annual Energy
Outlook for 2018 on February 6,2018, with a new natural gas forecast.
PacifiCorp has reviewed the calculation of the updated SAR published avoided cost rates with
EIA's 2018 natural gas forecast. This letter acknowledges that the updated SAR rates are accurate
and will become effective June 1,2018.
Any informal inquiries should be directed to Ted Weston at [phone].
Sincerely,
o.^,.D
