Invenergy LLC, a closely held renewable-energy,developer, said its California Ridge wind farm in Illinois has begun commercial operation.
U.S. government-owned utility Tennessee Valley Authority buys power from the project, which generates enough electricity for about 65,000 homes a year. Chicago-based Invenergy said today in an e-mailed statement. The wind farm is located on private land in Champaign and Vermilion counties and consists of 134 General Electric Co. wind turbines.
Invenergy operates wind farms in Illinois totaling 600 megawatts of capacity, it said.
