FirstEnergy Corp. subsidiary Potomac Edison is rebuilding a 500 kV transmission line in Frederick County, Md., to help enhance service reliability for existing customers and accommodate future electrical load growth in Maryland and West Virginia.

The project, FirstEnergy says, will replace equipment that is more than 40 years old along a three-mile section of the existing transmission line, using new conductors to increase the line's capacity by more than 60%. The company notes that the total cost of the project is approximately $18 million, with $13 million expected to be spent this year.

According to FirstEnergy, existing transmission structures also will be replaced with 14 new lattice steel structures.

The project was authorized by the PJM Interconnection board in December 2010 and is scheduled for completion this summer.
