Duke Energy has announced that it will expand its renewable power business with the development of a second wind power project in Cheyenne, Wyoming.

According to the company, the 42MW Silver Sage wind power project will be its third wind facility in the state of Wyoming. The company brought the 29MW Happy Jack wind power project in Cheyenne on line in September 2008 and plans to complete its 99MW Campbell Hill wind power project near Casper by the end of 2009.

As part of the Silver Sage project, Duke Energy has entered into 20-year power purchase agreements to sell all of the electricity generated at the site to Cheyenne Light Fuel & Power and Colorado-based Platte River Power Authority.

Duke Energy has said that the Silver Sage project will consist of 20 Suzlon wind turbines, each capable of generating 2.1MW of electricity. The purchase of these turbines will enable Duke Energy to start construction at Silver Sage in spring 2009 and target the end of 2009 for the project’s completion.

Duke Energy Generation Services develops, owns and operates electric generation for energy consumers, municipalities, utilities and industrial facilities. The company claims to specialize in developing innovative and environmentally sound generation services using a variety of fuels, including wind and other renewable energy sources.
