American Electric Power unit Appalachian Power filed an application with the Virginia State Corporation Commission requesting permission to make improvements and additions to the company’s existing high voltage transmission facilities in Tazewell and Buchanan Counties.
The proposed work will involve a new 7.5-mile Richlands-Whitewood 138 kV transmission line, a one-acre Whitewood switchyard, and associated improvements to the Richlands substation.
In the proposed plan, over 95 percent of new transmission line construction will take place in existing right of way.
The project is needed to address a potentially overloaded circuit projected to occur in 2017 as identified in a study conducted by PJM, Appalachian’s regional transmission organization. It will also improve reliability and reinforce the area’s electric infrastructure for future growth.
The proposed in-service date of the project is June 2017. The project will cost about $25 million. The filing covers only part of $50 million in planned improvements to Appalachian’s transmission system in Tazewell and Buchanan Counties announced in February 2014.
