Wind power in Tennessee has most potential in East Tennessee along the North Carolina border. The state has not passed renewable portfolio standard legislation and there is just one utility-scale wind farm with 15 operating turbines and previously 3 test turbines. The Tennessee Valley Authority (TVA), based in Knoxville, imports wind-generated electricity into its service area which includes Tennessee. US Senator Lamar Alexander from Tennessee is an outspoken critic of wind power.
According to engineers at TVA none of the windmills is now generating power because of maintenance and mechanical issues.
