Tennessee Valley Authority, a business owned by the U.S. government that supplies electricity for business and utility customers, has added 535 MW of renewable wind power from four farms in Iowa, Illinois and Kansas to its power grid.
New renewable wind power sources, which started delivery in January to the power grid of TVA, are 150 MW from White Oak Energy Center of NextEra Energy Resources in McLean County, Illinois; 201 MW from the Caney River wind farm of ENEL Green Power in Elk County, Kansas; 101 MW from the Lost Lakes wind farm of EDP Renewables North America in Dickinson County, Iowa; and 83 MW from the Pioneer Prairie site of EDP Renewables in Howard and Mitchell counties, Iowa. In 2010, the Pioneer Prairie site started to produce wind energy for TVA.
TVA now holds contracts with five wind farms, including the newly added renewable wind power sources, in the Midwest. It has a total of 542 wind turbines that could help generate more than 1,500 MW of clean and renewable energy. The total wind energy of TVA is 950 MW or over 3 million MWh per annum and it provides sufficient electricity to power over 200,000 homes in the service region of the government-owned corporation.
TVA's total clean and renewable energy capacity is over 5,600 MW and its clean energy contracts comprise 300 MW from Cayuga Ridge wind farm of Iberdrola in Illinois. TVA has not yet acquired Renewable Energy Credits connected with this contract, but has an option to purchase it in the future.
