Two Duke Energy wind power projects recently under construction in Pennsylvania and Wyoming are now on line and generating renewable electricity. Duke also says that Siemens Energy will join GE as a wind turbine supplier for a 200 MW wind farm Duke Energy is planning to build near Casper, Wyo.
Duke Energy's 70 MW North Allegheny Windpower Project is producing electricity for FirstEnergy under a long-term power purchase agreement (PPA). Duke Energy assumed ownership of the development project, located about 95 miles east of Pittsburgh, from Gamesa Energy USA earlier this year. North Allegheny represents Duke Energy's first commercial wind farm in the eastern U.S.
Duke Energy has also recently brought its 42 MW Silver Sage Windpower Project in Cheyenne, Wyo., on line. Silver Sage is the company's second wind farm in the area. Under the terms of two long-term PPAs, Duke Energy will sell all of the electricity generated at Silver Sage to Cheyenne Light Fuel & Power, a utility subsidiary of Black Hills Corp., and Colorado-based Platte River Power Authority.
In addition, Duke Energy has finalized its wind turbine supply plans for the 200 MW Top of the World Windpower Project, which is scheduled for construction in Converse County, Wyo., in 2010.
In addition to the already announced 66 GE 1.5 MW turbines to be installed at the site, Duke Energy has entered into a supply agreement with Siemens Energy for 44 2.3 MW wind turbines.
PacifiCorp signed a long-term PPA with Duke Energy in late August to buy all of the renewable power that will be generated by the Top of the World project.
