PSEG Fossil advances Sewaren repowering project at PJM


PSEG Fossil LLC has proposed a natural gas-fired generating facility located in Woodbridge Township, New Jersey, with a total capability of 625 MW with 625 MW of this output being recognized by PJM Interconnection as capacity.

PJM said in a December 2014 Facilities Study on the project that the proposed in-service date for this project is May 31, 2017. This study does not imply a Public Service Electric & Gas (PSE&G) commitment to this in-service date. This project, under queue number W2-023, will interconnect with the PSE&G transmission system at a new breaker position at the Sewaren 230-kV substation.

This combined-cycle project will consist of two combustion turbines and one steam turbine and will be located next to an existing power plant, the PJM study noted. The project still needs an Interconnection Service Agreement from PJM in order to complete the interconnection review process.

The New Jersey State Department of Environmental Protection has approved in the last couple of years air permitting that allows at the existing Sewaren facility the construction and operation of a 625-MW unit consisting of two combined cycle combustion turbines (CCCT) with two duct burners and two heat recovery steam generators (HRSGs), a 300-horsepower emergency diesel fire pump and a three-cell mechanical cooling tower. PSEG will shut down the six existing boilers, the eight peaking turbines and the natural gas-fired emergency generator within three months of commencement of operation of any one of the two new combustion turbines.

PSEG Fossil and PSE&G are both units of Public Service Enterprise Group (NYSE: PEG).
