RE: CASE NOS. GNR-E-12-02
IN THE MATTER OF THE ANNUAL REVISION AND UPDATED CALCULATION OF
THE ADJUSTABLE PORTION OF THE AVOIDED COST RATE(S) FOR EXISTING
PURPA CONTRACTS FOR AVISTA CORPORATION DBA AVISTA UTILITIES, FOR
IDAHO POWER COMPANY AND FOR PACIFICORP DBA ROCKY MOUNTAIN
POWER.
We have reviewed the information you have provided in your letter dated May 14, 2012,
notifying Idaho Power of revision of the adjustable portion of the Avoided Cost Rate(s) for existing
PURPA contracts. Idaho Power concurs that the model and calculations used by the IPUC staff for
Idaho Power Company are consistent with IPUC Order No. 28708.
On the page titled "Coistrip Adjustable Rate Calculation" and the section is titled "Coistrip
Fuel Cost from Avista FERC Form 1 for CY 2010", the correct data to use for this calculation is the
CY 2011 data, we confirmed that the actual data is the CY 2011 data as contained within the Avista
FERC Form 1 and we assume the page title is simply incorrect.
Sincerely,
C .yewe
