Calpine affiiate advances next Garrison project phase at PJM

Garrison Energy Center LLC continues to advance its plans for a 309-MW, gas-fired power project through the interconnection queue process at PJM Interconnection.

PJM, in a Facilities Study dated December 2014, said the company has proposed a 309 MWE (309 MWC, 309 MW MFO) natural gas-fueled 1×1 combined cycle facility. The project is to be located in the Garrison Oak Technical Park in Dover, Delaware, utilizing the same site as the company’s previous queue project W3-032A.

The combined facility will consist of two trains of one combustion turbine and one steam turbine (1×1 twice). PJM studied this latest project, under queue number, X2-067, as a 309 MW injection into the Delmarva Power and Light (DPL) system at the Cartanza 230-kV substation. The project was evaluated for compliance with reliability criteria for summer peak conditions in 2015.

The proposed in-service date, as stated in Attachment N, is June 01, 2016. The scope of the project as stated in the Impact Study Report, dated January 2013, remains relatively unchanged. The DPL portion of the project is projected to be completed approximately 60-72 months following an executed Interconnection Service Agreement (ISA) and Interconnection Construction Service Agreement (CSA), which are next steps in the queue process. The date estimates assume a normal land use and environmental permitting and approval process.

Said the Calpine (NYSE: CPN) website about this overall project: “The Garrison Energy Center is a 309-megawatt combined-cycle electric generating facility under construction that will enhance reliability for Delaware and the regional power market. The energy center will be located in the Garrison Oak Technological Park in Dover, Delaware, a site that will accommodate the addition of another 309 megawatts of generation capacity should market conditions warrant. The first phase of the project is expected to begin commercial operations by June 1, 2015. The plant will employ highly efficient combined-cycle technology with advanced environmental controls. Combined-cycle power plants are 40 percent more fuel efficient than plants employing older technologies, making them both cost-effective and low-carbon sources of electricity.”
