Jonesborough Solar Site

Washington County, Tennessee

On October 24, 2017, TVA issued a final environmental assessment (EA) and finding of no significant impact for its proposed purchase of power from the SR Jonesborough, LLC (an affiliate of Silicon Ranch Corporation) solar facility in Washington County, Tennessee. The proposed Jonesborough Solar Site is one project that incorporates two end users. The project would consist of two solar facilities, one with a direct current (DC) generating capacity of 5 megawatts (MW) and a second with a capacity of 1.35 MW, co-located on the same property owned by Silicon Ranch Corporation. TVA proposes to purchase power from the 5 MW facility, and the Aeroject Rocketdyne industrial facility located northwest of the project site would purchase power from the 1.35 MW facility.

The Jonesborough Solar Site, scheduled for completion in 2018, would occupy about 42.5 acres near Jonesborough, Tennessee and use photovoltaic panels mounted on multiple rows of ground mounted fixed-tilt metal racks to generate electricity. The 5 MW facility would connect to the Johnson City Power Board distribution network, which would transmit the power to the TVA network and the 1.35 MW facility will connect directly into the Aeroject Rocketdyne industrial facility.

The EA describes the anticipated environmental impacts of the construction and operation of the solar generating facilities and associated electrical connections.
