FirstEnergy places into service new 138-kV line in West Virginia

FirstEnergy (NYSE:FE) on Nov. 30 said that crews recently placed into service a new $98m, 138-kV transmission line in Harrison and Doddridge counties in West Virginia.

The line supports the electric demands of the area’s Marcellus Shale gas industry and helps enhance service reliability for almost 13,000 Mon Power customers in the Clarksburg and Salem areas, the company said.

The line is supported by 80 steel structures along an 18-mile corridor linking transmission substations in the Clarksburg and Sherwood areas, the company said, adding that the line route parallels an existing FirstEnergy transmission line for about 11 miles north of U.S. Route 50.

Anchoring both ends of the line are new or upgraded substation facilities, FirstEnergy said, noting that the substation near Clarksburg was expanded to accommodate new circuit breakers added to protect the new 138-kV line. 

The new substation near Sherwood, which was energized in 2014 at a cost of about $56m, was primarily built to support the growing electrical needs of a nearby gas plant, while also providing enhanced service reliability, the company said.

As reported, FirstEnergy subsidiary Potomac Edison also recently completed equipment upgrades at a substation in Jefferson County, W.Va., to enhance service reliability and help meet high winter demand for electricity for about 2,200 customers in the Ranson and Charles Town areas. 

The centerpiece of that $1m project was replacing one of the substation’s two distribution transformers with a larger unit, which increased the system’s capacity without having to expand the substation’s footprint or build new power lines, FirstEnergy said on Nov. 18.

Completed in October, the substation upgrade also included replacing existing fuses with a new circuit breaker to safeguard the new transformer when irregularities are detected on the electric system.
