Blue Sky Green Field wind project construction to begin in June

MILWAUKEE, May 30 /PRNewswire/ — We Energies has selected Alliant Energy WindConnect(R) as the general contractor for the Blue Sky Green Field wind project in northeast Fond du Lac County.

Project construction will begin in June 2007, with the first activities including road building, cable installation, and foundation work. The first turbine equipment is expected to arrive in November 2007. The project, which includes 88 turbines, is expected to be commercially generating power within one year from the start of activities at the site.

Boldt Construction, Hooper Corporation of Madison, and Baumhardt Sand and Gravel Inc. of Eden. In addition, Waukesha Electric Systems of Waukesha has been awarded the contract to manufacture and install the main substation transformer.
