Potomac Edison, a subsidiary of FirstEnergy Corp. (NYSE: FE), has started construction on a new substation designed to enhance system reliability for about 4,300 customers in the Brunswick, Jefferson and Petersville areas of Frederick County.

The company recently began site work for the project, which will be located on more than nine rural acres on Burgee Drive in Jefferson, just south of U.S. 340. The substation will tap into an existing overhead transmission line, reducing the need for additional construction, and will convert 230-kilovolt, high-voltage power to 34.5-kilovolt power that will then be distributed to the local system. The substation is expected to be in service in early 2023.

Potomac Edison continues to strengthen its infrastructure through investments designed to enhance reliability and improve operational efficiency. Late last year, the company completed two new distribution automation projects in Carroll and Garrett counties and installed 13 new substation reclosers in Frederick and Garrett counties to help reduce service interruptions.

In addition, Potomac Edison is replacing approximately 50 miles of underground electrical cable across its Maryland service territory each year. By replacing aging cable with new cable featuring a protective outer coating, Potomac Edison can proactively address potential service interruptions and enhance service reliability for customers.

Potomac Edison serves about 275,000 customers in all or parts of Allegany, Carroll, Frederick, Garrett, Howard, Montgomery and Washington counties. The company also serves about 151,000 customers in the Eastern Panhandle of West Virginia.
