FERC accepts interconnect for expanded Calpine plant in Delaware

The Federal Energy Regulatory Commission on Nov. 25 accepted PJM Interconnection‘s Sept. 30 filing of an executed Interconnection Service Agreement among PJM, Calpine Mid-Atlantic Development LLC and transmission owner Delmarva Power and Light for an uprated power plant.

This “First Revised ISA” is necessary to facilitate the interconnection of an additional 291 MW to Calpine’s pre-existing 565-MW facility for total capacity interconnection rights of 856 MW. 

This Calpine ISA supersedes an ISA among PJM, Conectiv Delmarva Generation and DPL. Effective July 2010, Calpine assumed all rights, responsibilities, and obligations under that prior agreement. “The Calpine ISA facilitates the interconnection to the PJM transmission system of an increase in 291 MW at Edge Moor Units EM6 and EM7 for a total of 856 MW at the Customer Facility, which consists of Hay Road Units #5, 6, 7, and 8 and Edge Moor Units EM6 and EM7, and is located in Wilmington, Delaware,” PJM told FERC.

“The Calpine ISA indicates that Calpine shall have capacity interconnection rights in the amount of 856 MW,” PJM added. “This amount of capacity interconnection rights includes 565 MW of capacity interconnection rights Calpine had at the same point of interconnection (‘POI’) prior to its interconnection request associated with the Calpine ISA, as well as 291 MW of capacity interconnection rights associated with such interconnection request.”

The title of the Calpine ISA reflects a new queue number (X1-074) and Calpine as the Interconnection Customer. In the new ISA, the facilities are described as:

  • One 565-MW combined cycle facility consisting of three combustion turbines and one steam turbine arranged in a 3×1 configuration (Units 5, 6, 7, and 8).
  • One 291-MW combined cycle facility consisting of one combustion turbine and one steam turbine arranged in a 1×1 configuration (Units EM6 and EM7).

Under the new ISA, on or before June 1, 2018, Calpine must demonstrate commercial operation of the two new generating units.
