PSEG Fossil pursues new gas-fired capacity to replace deactivated Edison units

PSEG Fossil plans natural gas-fired power plant to replace shut down coal units

PSEG Fossil LLC has proposed a natural gas-fired generating facility located in Edison, New Jersey, under PJM Interconnection Queue Position #AA2-125.

This queue position involves 580.08 MW and 504 MW of Capacity Interconnection Rights (CIRs), said a PJM study on the project, dated July 2015. 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, PJM noted. The Point of Interconnection for AA2-125 will be on PSE&G's transmission system at the Edison 138-kV substation.

"This project has claimed 504 MW of CIRs from the Edison units 1-3 that deactivated in June 2015," PJM noted in the study.

The intent of this Combined Feasibility/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.

PSE&G (a regulated utility) and PSEG Fossil (a power generator) are both subsidiaries of Public Service Enterprise Group (NYSE: PEG), which noted in its Feb. 26 annual Form 10-K report: "The National Park, Sewaren 6, Mercer 3, Salem 3, Burlington 8 and 11, Bergen 3, Edison 1, 2 and 3 and Essex 10, 11 and 12 peaking units are scheduled to be retired in June 2015. Salem 3 is expected to continue to be used as an emergency backup generator for the Salem nuclear site."

A PJM list of deactivated power plants, updated to June 29, shows that each of those three Edison units was deactivated on June 1 and that each is made of a cluster of four combustion turbines:

  • Edison 1, Units 11-14, with each having a capacity of 42 MW;
  • Edison 2, Units 21-24, with each having a capacity of 42 MW; and
  • Edison 3, Units 31-34, with each having a capacity of 42 MW.

Those 12 deactivated combustion turbines, multiplied by 42 MW each, comes out to a total of 504 MW, which is the CIR figure.
