Kingsport Power d/b/a AEP Appalachian Power, and its affiliate Appalachian Power Transmission Co., are working on the $105m Nagel Substation Expansion Project in Hawkins County, Tenn., that is designed to help ensure continued reliable electric service to customers, American Electric Power’s (NYSE:AEP) Appalachian Power said on Sept. 25.
The infrastructure upgrade project includes modernizing the existing equipment and adding additional facilities to support a lower voltage, the company said, noting that the work will reduce congestion on the transmission grid, as well as provide a more efficient and robust power system.
The project will be completed on existing company sites and easements, the company said, adding that the project will not affect other properties.
The Nagel substation is located in Hawkins County on the Tennessee-Virginia border about 10 miles west of the City of Kingsport. The company added that the substation expansion work will take place on the Tennessee side adjacent to Stanley Valley Road. On the Virginia side, the company said, two transmission lines will be moved about 200 feet to accommodate a new entry point into the substation.
As noted on a project fact sheet, the existing Nagel substation requires routine maintenance checks to ensure equipment is working at maximum efficiency. Replacing the existing equipment with modern technology reduces the need for maintenance by allowing the company to remotely monitor issues to help increase overall system performance and reduce congestion on the transmission system, the fact sheet noted.
The upgrades will increase reliability to customers in Kingsport, Tenn., Gate City, Va., and Bristol, Va., according to the fact sheet.
According to the project schedule, construction site work will occur this year; substation construction will begin in 2018; and the project will be in service in late 2019.
