TrAILCo’s 138-kV Osage-Whiteley line expected to be complete in August

FirstEnergy (NYSE:FE) subsidiary TrAILCo expects construction on its 138-kV Osage-Whiteley Project to be completed in August, a company spokesperson told TransmissionHub on June 24.

According to the company, the project entails 14.5 miles of new double-circuit, 138-kV transmission line connecting the Osage substation in Monongalia County, W.Va., to the Whiteley substation near Kirby in Greene County, Pa. That segment will ultimately interconnect with the 502 Junction substation near Mt. Morris, Pa.

Construction began in the spring 2012 with right-of-way clearing, the spokesperson said.

According to the company, the line is required to support Greene County under loss of transmission (N-1) contingency.

The spokesperson noted that PJM Interconnection’s current projected in-service date for the project is Aug. 15.

The Osage-Whiteley line and the work at the 502 Junction substation, which entails installing a 500/138-kV transformer and associated 138-kV breakers to interconnect the line for added transmission support in Greene County, cost more than $30m, the spokesperson said.

“The project is necessary to resolve low-voltage conditions at [the] Osage and Whiteley substations and to accommodate load growth associated with both substations,” he said.
