PJM works out interconnect revision for uprated PSEG Bergen power plant

PJM Interconnection filed on March 16 at the Federal Energy Regulatory Commission an executed Interconnection Service Agreement with PSEG Fossil LLC and transmission owner Public Service Electric and Gas for an uprated Bergen power plant.

The new PSEG Fossil ISA supersedes an older ISA and facilitates the interconnection of the Bergen Generating Station, currently a 1,259 MW facility consisting of two combined cycle units and one single combustion turbine generator, located in Ridgefield, N.J. The new ISA indicates that PSEG Fossil will have an increase in Maximum Facility Output of up to 85 MW over its previous interconnection, with the availability and amount of such increase dependent upon the completion and results of interim deliverability studies.

It further indicates that PSEG Fossil will have 1209.9 MW Capacity Interconnection Rights that it had at the Point of Interconnection prior to the interconnection requests associated with the new ISA and 60 MW of additional interim Capacity Interconnection Rights as a result of such interconnection requests.

This plant is made up of:

  • Unit 1: Maximum Facility Output of 675 MW. Unit 1 is a combined cycle unit. It is comprised of four combustion turbine generators and two steam turbine generators. The combustion turbines can run on gas or oil. The four combustion turbine generators are connected to the 138 kV system through two step-up transformers. The two steam turbine generators are connected to the 138 kV system through a single step-up transformer.
  • Unit 2: Maximum Facility Output of 560 MW. Unit 2 is a combined cycle unit made up of two combustion turbine generators and one steam turbine generator. The combustion turbines can run on gas or oil. Each generator has its own generator step-up transformer to 230 kV.
  • Unit 3: Maximum Facility Output of 24 MW. Unit 3 is a Power-Pac consisting of a single combustion turbine generator. It runs on gas and is connected to the 26 kV system through a single step-up transformer.

The PJM filing was not very specific about where this new capacity is coming from.

Notable is that PSEG Power New York LLC on Jan. 16 asked the New York State Public Service Commission for approval of its planned upgrade project for the General Electric turbines at the Bethlehem Energy Center (BEC). In that filing, it said: “The Upgrades are essentially the same as those that have recently been completed on four CTs at the PSEG Linden Generating Station located in Linden, New Jersey, and those planned to be completed on two CTs at PSEG’s Bergen Generating Station in Ridgefield, New Jersey. GE has sold over 100 of these upgrade packages, more than 60 of which are retrofits to existing units such as those at BEC. More than 35 of those are currently in operation. The proposed Upgrades will increase the electrical output of each turbine by approximately 7.2 percent, from a nominal 165 megawatts (MW) to 177 MW.”

The PSEG companies and Public Service Electric and Gas are all subsidiaries of Public Service Enterprise Group (NYSE: PEG).
