IDAHO POWER COMPANY'S RESPONSE TO FIRST PRODUCTION REQUEST OF COMMISSION STAFF Page 26 IDAHO POWER COMPANY CASE NO. IPC- E-06- FIRST PRODUCTION REQUEST OF COMMISSION STAFF RESPONSE TO REQUEST NO. 56 NO DOCUMENTS REQUESTED AND/OR NO DOCUMENTS RESPONSIVE TO THIS REQUEST REQUEST NO. 57: Please discuss how the operation of the Danskin plant will change once the Evander Andrews plant becomes operational. Please provide numerical data showing the monthly difference in the amount of expected generation from the Danskin plant with and without the Evander Andrews plant. RESPONSE TO REQUEST NO. 57: The new plant will have the lowest heat rate of Idaho Power s fleet of combustion turbines and would typically be dispatched first, followed by the Bennett Mountain plant and then the two remaining simple cycle turbines at Danskin. These turbines are all capable of partial load operation which provides Idaho Power with additional flexibility (by combining turbines and loading combinations) to meeting system demand. For a further analysis , please refer to the response to Request No. 18 concerning the AURORA model runs. 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. IDAHO POWER COMPANY'S RESPONSE TO FIRST PRODUCTION REQUEST OF COMMISSION STAFF Page 27 IDAHO POWER COMPANY CASE NO. IPC-06- FIRST PRODUCTION REQUEST OF COMMISSION STAFF RESPONSE TO REQUEST NO. 57 NO DOCUMENTS REQUESTED AND/OR NO DOCUMENTS RESPONSIVE TO THIS REQUEST REQUEST NO. 58: Did Idaho Power consider converting the Danskin plant to combined cycle as an alternative to the Evander Andrews plant? If so, please explain why that alternative was rejected and provide a copy of any analysis completed by Idaho Power justifying this decision. RESPONSE TO REQUEST NO. 58: Idaho Power has considered converting the existing Danskin units to combined cycle operation. This alternative was considered in both the 2002 and the 2004 Integrated Resource Plans. While converting the existing Danskin units to combined cycle operation was considered as an alternative in the 2004 I RP, it was not analyzed as a direct alternative to the 88 MW peaking resource included in the preferred portfolio (Portfolio 11). Twelve portfolios of resources were analyzed in the 2004 IRP. Converting the existing Danskin units to combined cycle operation was included in one of the 12 portfolios of resources (identifed as Portfolio 4 in the 2004 IRP). Results of the portfolio ranking analysis showed that Portfolio 11 finished in 1 st place and Portfolio 4 finished in th place. Details of this analysis are included in the 2004 IRP and the Technical Appendix thereto. In addition to the portfolio analysis , a table comparing the estimated capital and operating costs of the 88 MW peaker (which was assumed to be two 43. MW units) and the Danskin combined cycle conversion are also included in the Technical Appendix of the 2004 IRP. Since the peaker is anticipated to operate in peaking service (1-10% capacity factor) and the combined cycle conversion is expected to operate in intermediate (20-50% capacity factor) or baseload service (50-85% IDAHO POWER COMPANY'S RESPONSE TO FIRST PRODUCTION REQUEST OF COMMISSION STAFF Page 28 capacity factor), the expected usage or duty cycle of the resource must be considered when comparing estimated operating costs. 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. IDAHO POWER COMPANY'S RESPONSE TO FIRST PRODUCTION REQUEST OF COMMISSION STAFF Page 29 IDAHO POWER COMPANY CASE NO. IPC-06- FIRST PRODUCTION REQUEST OF COMMISSION STAFF RESPONSE TO REQUEST NO. 58 NO DOCUMENTS REQUESTED AND/OR NO DOCUMENTS RESPONSIVE TO THIS REQUEST 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? 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.

RESPONSE TO REQUEST NO. 66: No. In accordance with Idaho Code 961-526, the Company will not pursue construction of a generation facility without a Certificate of Convenience and Necessity. However, the Company would also hope that if the Commission were to deny the Company s application for a Certificate of Convenience and Necessity, the Commission would provide guidance that would assist the Company in pursuing an alternative to construction of the Evander Andrews power plant.

Idaho Power Company is also presently in the process of obtaining a license amendment for the Shoshone Falls project. The Company anticipates filing the final license amendment application with the Federal Energy Regulatory Commission in July 2006.
