How much electricity will the wind turbines produce?
TVA has installed three turbines on Buffalo Mountain in Anderson County, Tennessee. Each has a generating capacity of 660 kilowatts. Together, these three turbines produce some 6 million kilowatt-hours per year — enough to serve more than 400 typical Valley households. Do wind turbines produce electricity all the time? No, but when the turbines aren’t operating, other resources will continue to supply power as reliably as ever. Although wind speed varies according to the time of day, season, height above ground, and terrain, proper siting in a breezy location away from large obstructions will enhance a wind turbine’s performance. How are wind sites selected? The turbines must be situated where the wind is relatively steady and strong. Windy sites in environmentally sensitive areas will be excluded. For cost-control reasons, it’s helpful to have access to transmission or distribution lines nearby, and access by road is needed for construction and maintenance. Will the turning rotor bla
