January 2005 - The Tennessee Valley Authority has completed the expansion of its Buffalo Mountain Wind Park with the addition of 15, 1.8-MW wind turbines, bringing the total installed capacity to 29 MW. Three, 660-kW turbines have been in operation at the site since 2000.
TVA has contracted with developer Invenergy LLC to purchase the wind output for 20 years to supply its Green Power Switch renewable energy program, which has faced supply shortages in recent months. The Buffalo Mountain Wind Park is the largest wind installation in the Southeast.
