Potomac Edison, a subsidiary of FirstEnergy Corp., is rebuilding a power line and constructing a new substation to enhance service reliability for more than 1,200 electric customers in mountainous, densely forested northern Frederick County, Maryland.
The $4 million project includes rebuilding nearly six miles of a 12-kilovolt (kV) distribution line from Wolfsville, Md., to a new substation that will be built near Foxville.
Construction crews are setting new utility poles and replacing mostly single-wire distribution circuit with a new three-wire line to increase capacity. Smart technology capable of detecting irregular conditions also will be installed on the line. The line is expected to be completed later this summer.
The new substation site is located in the Foxville area and will be interconnected to a nearby 138-kV transmission line. The company plans to start construction on the substation later this summer with plans for it to be completed and operational before year-end.
The new substation will include a transformer that converts higher transmission voltages to lower distribution voltage levels that can be used to power electrical devices at homes and businesses. The substation also will contain a circuit breaker and relay devices, which automatically interrupt the flow of electricity to protect equipment from falling trees, vehicle accidents or lightning strikes.
The project is one of numerous distribution and transmission infrastructure projects totaling about $156 million that FirstEnergy Corp. plans to work on in 2018 for the Potomac Edison service area.
