The utility’s senior vice president of power supply, Lisa Grow, said: "In the end the RFP no longer provided a competitive resource.
"Since issuing our RFP more than 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."
She said Idaho Power is still looking to add renewable power, including wind, geothermal and solar, to its portfolio.
But the utility said that the amount of wind-powered generation on its system exceeds the amount prescribed in the company’s integrated resource plan, last revised in 2009.
Among Idaho Power’s wind PPAs is a 20-year contract to buy 183MW of wind power from Idaho Wind Partners I, a grouping of 11 wind farms under development.
The projects are owned jointly by GE, Atlantic Power, Exergy Development Group and Reunion Power.
