RE:CASE NOS. GNR-07-
IN THE MATTER OF THE ANNUAL REVISION AND UPDATED CALCULATION
THE ADffiSTABLE PORTION OF THE AVOIDED COST RATE(S) FOR EXISTING
PURP A CONTRACTS FOR A VISTA CORPORATION DBA A VISTA UTILITIES, FOR
IDAHO POWER COMPANY AND FOR P ACIFICORP DBA UTAH POWER AND LIGHT
COMPANY.
We have reviewed the infonnation you have provided in your letter dated May 24, 2007
notifying Idaho Power of revision of the adjustable portion of the Avoided cost rate(s) for existing
PURP A contracts.. Idaho Power concurs that the model and calculations used by the IPUC staff for
Idaho Power Company are consistent with IPUC Order 28708.
In reviewing the letter it was noticed that the calculation of the approved gas price of $7.
less the $0.87 decrease resulted in a new price of $6.94. Mathematically, this calculation should
result in a new price of $6.93. Idaho Power contacted Rick Sterling and discussed this calculation;
the $0.01 difference is a result of mathematical rounding of the components within this calculation.
Based upon our discussion with Rick, the $6.94 value is acceptable.
Sincerely,f~'
