West Penn Power Connecting Two Solar Projects to Electric Grid

Pennsylvania solar farms to generate 220 megawatts of renewable energy

GREENSBURG, Pa., July 19, 2023 -- West Penn Power, a subsidiary of FirstEnergy Corp. (NYSE: FE), has begun work to connect a pair of solar energy projects in Fulton and Franklin counties to the electric grid. The two solar farms are being developed by global power company AES Corporation and will generate 220 megawatts of clean, renewable energy designated for a customer power purchase agreement.

For the first project, West Penn Power will expand its McConnellsburg substation in Fulton County and add a new terminal at the substation to provide a connection point for a 70-megawatt solar farm that AES is developing in Ayr Township.

The second project is a 150-megawatt solar farm in Peters and Saint Thomas Townships in Franklin County. West Penn Power is constructing a new substation on McDowell Road that will serve as an interconnection for the farm. AES will build a 138-kilovolt line from the solar farm into the substation, and West Penn Power will add a 378-foot loop to connect the substation to one of its existing 138-kilovolt transmission lines that runs between the company's Guilford and McConnellsburg substations. The company will make upgrades at the Guilford and McConnellsburg substations to support the solar project as well.

West Penn Power expects to complete the connection work for both projects in late 2023, with the two solar farms expected to be in service and delivering clean energy in early 2024.
