Invenergy said this week its 1,485 MW combined-cycle natural gas-fired power plant in northeast Pennsylvania has entered service.

The Lackawanna Energy Center has the capacity to power more than one million homes. The plant is selling power to PJM Interconnection, the regional power grid that serves all or parts of 13 states and the District of Columbia.

Invenergy CEO Michael Polsky claimed the plant, located near Scranton in Lackawanna County, is the largest and “most technically sophisticated” power plant the company has ever developed, built and operated.

The plant features a single-shaft design where each of the three 500 MW power islands are comprised of a combustion turbine and steam turbine that share a single generator, maximizing facility efficiency while still allowing for the independent operation of each gas turbine.

Cabot Oil & Gas Corp. signed a deal two years ago to exclusively supply the facility. South Jersey Resources Group LLC, a subsidiary of South Jersey Industries, provides fuel management services.

The center is the latest gas-fired power plant to come online in the state. An abundance of shale gas in the region has prompted a building boom in the sector, particularly in Ohio and Pennsylvania. There are 24 gas-fired facilities under construction or being upgraded in PJM, according to the grid operator’s services queue.
