Calpine working capacity addition at Delaware site through PJM system

Calpine Mid-Atlantic Development LLC has proposed an 80 MWC (80 MWE) upgrade to its prior queue project X1-074, with the combined X1-074/AA1-033 project now a 936 MFO (936 MWC) resource.

X1-074/AA1-033 is a natural gas-fueled combined cycle facility consisting of Hay Road Units 5, 6, 7, and 8, and Edge Moor Units 6 and 7, and is located in Wilmington, Delaware. PJM Interconnection said in a study dated September 2015 that it studied AA1-033 as an 80 MW injection into the Delmarva Power and Light (DPL) system at the Hay Road 230 kV substation and evaluated it for compliance with reliability criteria for summer peak conditions in 2018. The planned in-service date is June 18, 2018.

AA1-033 will utilize the same Point of Interconnection (POI) as prior queue project X1-074 at the Hay Road 230-kV Substation.

PJM Queue project AA1-033 is a request for an 80 MW Maximum Facility output (MFO) upgrade to the existing X1-074 1×1 combined cycle facility. The total MFO of AA1-033 will be 371 MW after the upgrade. The AA1-033 combined cycle facility consists of one 173.5-MW steam turbine and one 215-MW combustion turbine.

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 Calpine Mid-Atlantic.
