PSEG Fossil LLC has proposed a natural gas generating facility located in Sewaren, New Jersey, said PJM Interconnection in a March 2015 study on the project.
The installed facilities will have a total capability of 568 MW with 509 MW of this output being recognized by PJM as capacity. The proposed in-service date for this project is May 31, 2018. This study does not imply a Public Service Electric & Gas (PSE&G) commitment to this in-service date. This project, under queue No. Z2-089, has claimed 509 MW of Capacity Interconnection Rights (CIRs) from the retiring Sewaren 1, 2, 3, 4 and 6 units.
Project Z2-089 will interconnect with the PSE&G transmission system via a new breaker position at the Sewaren 230-kV substation.
The intent of this System Impact Study is to determine a plan, with approximate cost and construction time estimates, to connect the subject generation interconnection project to the PJM network at a location specified by PSEG Fossil. This study is a mid-point of the queue process, which culminates with an Interconnection Service Agreement. Both PSEG Fossil and PSE&G are subsidiaries of Public Service Enterprise Group (NYSE: PEG).
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.
