Appalachian Power and an American Electric Power affiliate, AEP Appalachian Transmission Co. filed a joint request with the Virginia State Corporation Commission for approval to build the Cloverdale Extra High Voltage (EHV) Transmission Improvements Project in Botetourt County.
The project is expected to cost about $237 million. Appalachian Power announced the project in January. This filing begins a state-level review.
The project involves construction of facilities in and near the existing Cloverdale Substation. The work ultimately will involve construction of a new EHV substation yard on property the company owns, expansions and upgrades to the existing EHV yards at the Cloverdale Substation and installation of new transmission lines to tie the facilities together.
The project is intended to address voltage and thermal problems, transmission congestion and equipment obsolescence that have been identified in the region by PJM Interconnection, an independent transmission system operator.
