PSEG Keys Energy Center


For the Local Information & Supplier Website – VISIT WWW.PSEGKEYSENERGYCENTER.COM

The PSEG Keys Energy Center, owned by PSEG Fossil, a subsidiary of PSEG Power, began construction in 2015 of the PSEG Keys Energy Center, a new clean, natural gas-fired power plant in Prince George’s County, Maryland.

The PSEG Keys Energy Center, a 755-MW combined cycle plant, represents an $825-$875 million investment and is targeted to be in operation in 2018.

The Maryland electricity ratepayer is not subsidizing or guaranteeing any portion of the revenue of the plant.  The plant will participate in the capacity and energy markets established by PJM for wholesale electric generators.


The PSEG Keys Energy Center project will be constructed on a 180+ acre parcel of land previously used for a sand and gravel mining operation. The site is located north of North Keys Road approximately 1.25 miles east of Brandywine, Maryland.

Site Selection

A siting evaluation was conducted to select an appropriate location for the project in Prince George’s County, Maryland. The site selection considerations included:

  • Location—rural versus developed area, existing land use
  • Zoning—industrial versus agricultural
  • Visual impacts
  • Noise impacts
  • Ecological impacts
  • Air quality
  • Water supply
  • Socioeconomic impacts
  • Electrical transmission capacity
  • Natural gas supply

A priority for site selection was to identify suitable property that had a permitted use within the current zoning designation. The proposed site was previously used as a gravel mine and is currently zoned as open space (O-S) with electric power facilities identified as a permitted use within the zone. The proximity to linear facilities was also a key factor in site selection. The proposed site has an existing 500-kV transmission line right-of-way located on the western side of the property allowing the project to directly connect to the electrical grid.  A major interstate natural gas pipeline is in close proximity. Therefore, the site was determined to be suitable for the project from engineering, environmental, and socioeconomic perspectives.

Clean, reliable energy

The PSEG Keys Energy Center will bring about 755 megawatts (MWs) of highly efficient generating capacity to the state of Maryland and region supporting electric system reliability.  This represents enough generating capacity to power 500,000 homes. The plant will run on clean, efficient natural gas. 

Environmentally responsible energy

PSEG Fossil is committed to providing Maryland and the region with reliable and environmentally responsible energy. The PSEG Keys Energy Center will meet all applicable federal and state emissions regulations.

The new plant will be a highly efficient combined-cycle unit with a combustion turbine, heat recovery steam generator, and steam turbine – one of the cleanest technologies available for electric generation.

The unit will be equipped with state-of-the-art emissions control technology, including:

  • A combination of low nitrogen oxide (NOx) combustors and a selective catalytic reduction (SCR) system to reduce NOx emissions
  • An oxidation catalyst to reduce carbon monoxide emissions
  • Air-cooled condensers to continuously recycle water for cooling purposes

Economic benefits

The PSEG Keys Energy Center will represent a major investment in the local and regional economy.

Over the 40-year life of the project, it is anticipated that the PSEG Keys Energy Center will bring significant new tax revenue – approximately $640 million in various taxes – to Charles County, the State of Maryland, Maryland-National Capital Park and Planning Commission, Prince George’s County and the Washington Suburban Transit Commission. 

In addition, as part of the Community Foundation Agreement, PSEG Power will donate $3 million toward the construction of a new Southern Area Aquatic and Recreation Complex (SAARC) in Brandywine, Maryland. The SAARC will include indoor aquatic space, a gymnasium, a fitness room and flexible programmable space. For more information, visit the Prince George’s County Department of Parks and Recreation website.

The project will generate about 700 jobs during the two-year construction phase. More than 20 permanent jobs will be created to run the new plant when it becomes operational. 

Key Dates

May 2014 – Keys Energy Project bid into and cleared PJM capacity auction.
October 16, 2014 – Community Foundation Agreement established.
October 31, 2014 – Maryland Public Service Commission approved the project.
November 17, 2014 – Public hearing held in Brandywine.


No new transmission lines will be required as part of the project. The PSEG Keys Energy Center will connect to the Potomac Electric Power Company (PEPCO)/PJM 500 kV transmission line adjacent to the property.

Fuel to run the plant is readily available. The PSEG Keys Energy Center will connect to a major interstate natural gas pipeline within close proximity of the site.
