20-MW Wind Farm and Associated Energy Storage Facility Environmental Assessment

The Tennessee Valley Authority proposes to construct and operate a wind farm in Tennessee. TVA also proposes to construct and operate a Regenesys™ Energy Storage facility near the selected wind farm site. The wind farm would demonstrate a technology for generating electric power with minimal environmental pollution to be marketed through TVA’s Green Power Switch® program and would consist of 13 to 16 wind turbines. The Regenesys facility would demonstrate an effective technology for storing the energy generated by the wind farm and releasing it at times of high energy demand.

This final environmental assessment examines the potential effects of building on Buffalo Mountain in Anderson County (Alternative 1), building on Stone Mountain in Johnson County (Alternative 2), or not building a 20 MW wind farm and associated energy storage facility (Alternative 3).


The public summary and the entire environmental assessment can be viewed by section, as noted below (PDF files; require Adobe Acrobat Reader).
