Helicon, Alabama
Power Supply Improvement Project

Lawrence and Winston Counties, Alabama
On April 7, 2011, TVA issued an environmental assessment and a finding of no significant impact for its proposal to improve the existing power supply in east Winston County, Alabama, by constructing and operating approximately 6.5 miles of new 161-kilovolt (kV) transmission line.  The new transmission line would serve to reduce power outages and relieve equipment that is near overload in the Helicon area by providing a reliable source of power to Cullman Electric Cooperative’s (EC) planned new 161-kV substation.

Approximately 4.5 miles of new transmission line would be built on new right-of-way (ROW) 100 feet in width, and about 2 miles of the transmission line would utilize the existing 75-foot-wide ROW of Cullman EC’s Jones Chapel-Addison 46-kV Transmission Line, which is no longer in service.  TVA would purchase additional rights over the existing ROW, thus sharing this existing easement with Cullman EC, and would purchase an additional 25 feet of new ROW (12.5 feet on either side).  The proposed ROW would occupy about 79 acres.  The proposed new 161-kV transmission line would connect Cullman EC’s planned Helicon 161-kV Substation to TVA’s existing Addison 161-kV Tap Line, near the existing Addison 161-kV Substation.  The proposal also includes the installation of one switch structure and modifications to two existing switch structures.

Additional information on the project is available including background information, maps, and a project schedule.
