Wind power in Tennessee has most potential inEast Tennessee along the North Carolina border.[1] The state has not passedrenewable portfolio standard legislation and there is just one utility-scalewind farm with 15 operating turbines[2] and previously 3 test turbines.[3] TheTennessee Valley Authority (TVA), based inKnoxville, imports wind-generated electricity into its service area which includesTennessee. US SenatorLamar Alexander from Tennessee is an outspoken critic of wind power.[4]

According to engineers at TVA none of the windmills is now generating power because of maintenance and mechanical issues.
Before expanding the wind plant at Buffalo Mountain, TVA proposed fourteen wind turbines on a ridge north of Beech Mountain, within 11 miles of theAppalachian Trail.[5]
Until 2009 the TVA operated threewind turbines with a combined generation capacity of 2 MW "as a test bed". TVA stopped operating the three turbines in 2009 due to maintenance issues. In 2021 TVA announced no access would be allowed in the area while it is removing the three original test wind turbines that "reached their end of life."[3] It purchases the output of 15 wind turbines built in 2004 and owned byInvenergy that have a combined capacity of 27 MW.[6][7][8][9][10]
2012-Invenergy - 400MW - Bishop Hill Wind Energy Center,Henry County, Illinois 200 megawatts generated by General Electric 1.5-megawatt SLE turbines. This facility began delivery in July 2012.
Clean Line Energy LLC is proposing 700-mile power transmission line to bring wind energy from Oklahoma and to the Tennessee Valley. The TVA would import 1,750 megawatts, about half of the power that could be transmitted. Developers began in 2007 to seek regulatory approval for the $2 billion project, but the approvals needed to start construction aren't expected to be in place until at least 2020.[12][13][14][15][16] The project faces opposition, particularly in Arkansas.[17]
