PSEG to Close Two Coal Plants in New Jersey

LCG, October 6, 2016--PSEG announced yesterday that it will retire the Hudson Generation Station in Jersey City and the Mercer Generation Station in Hamilton Township on June 1, 2017. Hudson was opened in 1968 and has an electric generating capacity of 620 MW. Mercer was opened in 1960 and has a capacity of 632 MW. PSEG is evaluating all options for future use of the sites.

The president and chief operating officer of PSEG Power stated, "The sustained low prices of natural gas have put economic pressure on these plants for some time. In that context, we could not justify the significant investment required to upgrade these plants to meet the new reliability standards. The plants have been infrequently called on to run and neither plant cleared the last two PJM capacity auctions. The plants' capacity payments have been critical to their profitability and PSEG's ability to continue to invest in modernizing them."

PSEG currently is investing over $600 million in a new state-of-the-art combined-cycled gas plant in Sewaren, New Jersey (Sewaren 7) that is scheduled to be operational in 2018. Additional new combined-cycle plants in planned in Connecticut (Bridgeport Harbor 5) and Maryland (Keys Energy Center).
