In November 2011, MidAmerican Energy and Siemens entered into a turbine supply agreement for an additional 176 wind turbines to be constructed at three sites in Iowa. Each turbine is capable of producing 2.3 MW of energy.
Siemens will provide SWT-2.3-108 wind turbines for MidAmerican Energy's recently announced 103.5 MW Vienna wind project; 200.1 MW Eclipse wind project; and 101.2 MW Morning Light wind project. The contract includes a five-year service, maintenance and warranty agreement.
Siemens also will provide one additional 2.3 MW wind turbine, which will be installed at MidAmerican Energy's Rolling Hills wind project.
The nacelles and blades for the three projects will be manufactured at Siemens' nearby manufacturing facilities in Fort Madison, Iowa, and Hutchinson, Kan.
