FirstEnergy has begun work to build a new 138kV substation and associated transmission lines in Ohio, US.

The Black River Substation will supply power to the City of Lorain and also provide power to support the new arc furnace being built by Republic Steel, a supplier of steel.

FirstEnergy Ohio Edison utility regional president Don Moul said, "The Republic Steel expansion is expected to bring nearly 450 new jobs to the region, and we’re very pleased to support this important economic development project through the construction of our new substation."

FirstEnergy subsidiary American Transmission Systems will own and operate the Black River Substation, and also be in charge of the design, planning, construction and commissioning activities.

The substation is expected to be in service by June next year.

FirstEnergy said the substation is expected to replace the Edgewater Substation and transmission lines along the Lake Erie waterfront.

FirstEnergy owns ten electric distribution companies and has a diverse generating fleet with a capacity of approximately 23,000MW.
