PJM works out revised interconnect deal for uprated Linden power plant

PJM Interconnection on March 16 filed with 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 power plant.

This new PSEG Fossil ISA supersedes a prior ISA among the same parties. The new ISA facilitates the interconnection of the Linden Generating Station, currently a 1,570-MW facility located in Linden, New Jersey. It covers an increase in Maximum Facility Output of up to 170 MW over the previous interconnection, with the availability and amount of such increase dependent upon the completion and results of interim deliverability studies. The PSEG Fossil ISA further indicates that PSEG Fossil will have 1,566.2 MW of Capacity Interconnection Rights that it had at the Point of Interconnection prior to the Interconnection Requests associated with the PSEG Fossil ISA, and 120 MW of additional interim Capacity Interconnection Rights as a result of these interconnection requests.

The PJM filing was unclear on where this new capacity comes from. The ISA said this plant consists of:

  • The 615-MW Linden #1 CC is a combined cycle unit, which is comprised of two combustion turbine generators and one steam turbine generator. The combustion turbines can run on gas or oil. The steam turbine can connect to two different 138 kV buses through two different step-up transformers. One combustion turbine generator connects to the 138 kV system through a single step up transformer. The other combustion turbine generator connects to the 230 kV system through a single step-up transformer.
  • The 615-MW Linden #2 CC is a combined cycle unit, which is comprised of two combustion turbine generators and one steam turbine generator. The combustion turbines can run on gas or oil. The three generators are connected to the 230 kV system through three individual step-up transformers.
  • Linden #5  and #6 are each a single combustion turbine generator of 86 MW of capacity each. Each generator runs on oil or gas and is connected to the 230 kV system through a shared step-up transformer.
  • Linden #7 and #8 are each a single combustion turbine generator of 84 MW of capacity each. Each generator runs on oil or gas and is connected to the 138 kV system through a shared step-up transformer.

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.”
