Compass Gas Thermal IPP Project U.S.A

JERA acquired equity interest in three natural gas-fired thermal power generation plants (the “Compass Portfolio”) in the northeastern United States.

The Compass Portfolio includes the Marcus Hook Energy Center, in suburban Philadelphia, and the Dighton and Milford Energy facilities in Massachusetts, with an aggregate power generation capacity of 1,123 MW. Power and capacity from the Marcus Hook Energy Center is sold mainly into the PJM Interconnection (PJM) wholesale electricity market, and power and capacity from the other facilities is sold into the ISO New England (ISO-NE). In addition, the Marcus Hook Energy Center has a contract for capacity with the Long Island Power Authority, a power distribution utility.
