Calpine’s Garrison project due for commercial operation around June 1

Calpine Corp.’s (NYSE: CPN) Garrison Energy Center LLC on April 22 filed with the Federal Energy Regulatory Commission a notice of self-certification as an exempt wholesale generator.

Garrison will own and operate an approximately 309 MW (projected summer rating) natural gas- and oil-fired facility in Dover, Delaware. The facility is currently under construction and the first phase of the project is expected to begin commercial operations on or about by June 1, 2015.

The commission has already authorized Garrison to make wholesale sales of energy, capacity, and certain ancillary services at market-based rates, and Garrison is a “public utility” under the Federal Power Act.

A company contact is: Sarah G. Novosel,  Senior Vice President, Government Affairs, and Managing Counsel, Calpine Corp., 875 15th Street NW, Suite 700, Washington, DC 20005, (202) 777-7623,

Said the Calpine website about this 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.”

In terms of that second phase of this project, Garrison Energy Center LLC continues to advance its plans for that next 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 (which is the first phase that is almost completed).

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.
