Aspen Grove - Westhaven Transmission Line
Williamson County, Tennessee
In order to serve the rapidly growing demand for electricity in western Williamson County, Tennessee, Middle Tennessee Electric Membership Corporation plans to build a substation near the Westhaven Subdivision. TVA proposes to build a 161-kV transmission line connecting this new Westhaven Substation with MTEMC’s existing Aspen Grove Substation.
TVA has reviewed the public comments regarding the proposal and evaluated the environmental data on alternative routes for the transmission line. TVA has identified its South Mack Hatcher Parkway alternative as the preferred route.
TVA has prepared this final environmental assessment evaluating the effects of building approximately 5.25 miles of 161-kV transmission line between the Aspen Grove Substation and the Westhaven substation. Additional information on the planning process is available at Williamson County Power Supply Upgrades.
