Extensions are going ahead to two wind projects already built or in the works in Washington and Oklahoma. Energy Northwest is adding 15.6 MW to its 48 MW Nine Canyon project, completed in August 2002, and FPL Energy says it will double the size of its Oklahoma Wind Energy Center to 102 MW. The Nine Canyon extension is instead of a project by Energy Northwest at nearby Zintel Canyon, for which it has not bagged sufficient power purchase agreements. The Nine Canyon expansion will be completed in time to take advantage of the federal Renewable Energy Production Incentive (REPI), which ends September 30. Although the money available in the REPI may be reauthorised, says the company's Gary Miller, Energy Northwest cannot take the chance it would be authorised late or not at all. Renewable Energy Systems, a British-owned developer that built Nine Canyon, will construct the extension using 12 Bonus 1.3 MW turbines. Meanwhile, FPL Energy says it has signed a contract with Oklahoma Gas and Electric (OG&E) for a 51 MW project extension using GE turbines. It is already constructing 51 MW for the Oklahoma Municipal Power Authority using 34 GE Wind Energy 1.5 MW turbines (Windpower Monthly, May 2003). Although the OG&E portion of the project requires state regulator approval, FPL says the entire 102 MW will be online by December 31, when wind's federal production tax credit is scheduled to end.
