IDAHO POWER COMPANY'
SECOND SUPPLEMENTAL
RESPONSE TO THE FIRST
PRODUCTION REQUEST OF
COMMISSION STAFF
COMES NOW, Idaho Power Company ("Idaho Power" or "the Company")
and, in response to the First Production Request of the Commission Staff to Idaho Power
Company dated June 16, 2006, herewith submits the following supplemental information:
REQUEST NO. 61: Please discuss the status of Idaho Power s plans to
upgrade the Borah-West transmission path. Was an upgraded Borah-West transmission
path assumed to be available in the evaluation of RFP bids? Were transmission cost
estimates for projects east of the Treasure Valley area less in the March 2005 RPF than
in previous thermal RFPs due to an assumed upgraded Borah-West transmission path?
IDAHO POWER COMPANY'S SECOND SUPPLEMENTAL RESPONSE TO THE
FIRST PRODUCTION REQUEST OF COMMISSION STAFF, Page
RESPONSE TO REQUEST NO. 61: Idaho Power did not receive any
bids in this RFP that would require energy to cross the Borah-West transmission
constraint. As a result , upgrades to the Borah-West transmission path did not affect
favorably or unfavorably the evaluations of any bids received in this RFP.
The response to this request was prepared by F. Gregory Hall , Principal
Engineer, Idaho Power Company, in consultation with Barton L. Kline, Senior Attorney,
Idaho Power Company.
FIRST SUPPLEMENTAL RESPONSE TO REQUEST NO. 61: The Borah
West upgrade included in the 2004 IRP is intended to support anticipated renewable
generation that will be located in Eastern Idaho. Because this upgrade is required for
generation requirements independent of the peaking resource, it cannot be regarded as
an alternative to construction of an additional peaking resource to meet electrical
demands.
The response to this request was prepared by F. Gregory Hall , Principal
Engineer, Idaho Power Company, in consultation with Barton L. Kline, Senior Attorney,
Idaho Power Company.
SECOND SUPPLEMENTAL RESPONSE TO REQUEST NO. 61: The
Borah West up rate project will provide a 250 MW increase in East to West transfer
capability on the Borah West transmission path. Construction is presently underway
all major phases of the project. May 2007 is the anticipated project completion date.
The four major components of the project and their corresponding construction status
are listed below:
