Calpine files for market authority for 309-MW Delaware project

Garrison Energy Center LLC, which has a gas-fired power project in Delaware due for a commercial operations start in mid 2015, filed on Dec. 30 at the Federal Energy Regulatory Commission for market-based rate authority.

Garrison will own and operate an approximately 309 MW (projected summer rating) natural gas-fired facility in Dover, Delaware, within the PJM Interconnection market and the PJM East and 5004/5005 sub-markets. The Garrison Energy Center is currently under construction, and the first phase of the project is expected to begin commercial operations no later than June 1, 2015.

All of Garrison’s membership interests are held by Calpine Holdings LLC, all of the membership interests of which are held by Calpine Development Holdings. Calpine Development is a wholly owned subsidiary of Calpine Power, which is a wholly owned subsidiary of Calpine Corp. (NYSE: CPN).

Notable is that Garrison Energy Center LLC continues to advance its plans for a second 309-MW, gas-fired project through the interconnection queue process at PJM. 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 plant nearing completion.

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 system at the Cartanza 230-kV substation.
