MidAmerican Energy awarded a contract to Siemens Energy to supply wind turbines for its 407-MW project expansion. Siemens will supply 176 turbines to be installed at four sites in Iowa. The orders follow the completion of Siemens projects in Iowa exceeding 593 MW of wind capacity. Siemens is expected to provide SWT-2.3-108 turbines for MidAmerican’s 103.5-MW Vienna project, to be located in Marshall and Tama counties; its 200.1-MW Eclipse project in Guthrie and Audubon counties; the 101.2-MW Morning Light project in Adair County; and one 2.3-MW turbine at the Rolling Hills project. The contract includes a five-year service, maintenance, and warranty agreement. The nacelles and blades for the turbines will be manufactured at Siemens’ facilities in Fort Madison, Iowa, and Hutchinson, Kan.
American Electric Power began operating the 580-MW Dresden natural gas-fired combined-cycle power plant. AEP purchased the partially built Dresden plant from Dominion Resources in 2007 for about $85 million. AEP accelerated construction in January 2011. Total costs for the plant were about $366 million. The Dresden plant will supply electricity to AEP’s Appalachian Power customers in West Virginia, Virginia and Tennessee.
