Idaho Power has closed a request for proposals (RFP) seeking to purchase about 150MW of wind-powered generation by 2012.

The RFP generated considerable interest from wind developers and Idaho Power had negotiated a contract with the clear front runner.

However, the firm closed the RFP without awarding a contract, since it could not reach a final agreement with the other entity.

Idaho Power senior vice president of power supply Lisa Grow said that since issuing the RFP over a year ago, the wind energy market has changed dramatically and prices for Power Purchase Agreements (PPAs) acquired under the Public Utility Regulatory Policies Act of 1978 (PURPA) process have decreased.

“In light of these changes, we expect to be able to acquire energy resources without concluding the RFP at this time,” Grow said.

At present, Idaho Power has contracted over 600MW from PURPA projects, which adds to the company’s resource portfolio.
