FERC to review gas pipeline expansion that will support Calpine power project

The staff of the Federal Energy Regulatory Commission will prepare an environmental assessment (EA) on the White Oak Mainline Expansion Project, involving construction and operation of facilities by Eastern Shore Natural Gas Co. in Chester County, Pa., and New Castle County, Del., to serve a new Calpine Corp. (NYSE: CPN) power plant.

The commission said in a Jan. 22 notice that it will use this EA in its decision-making process to determine whether the project is in the public convenience and necessity. The scoping period where input will be taken on what should be covered in the EA will close on Feb. 23.

The project would provide 45,000 dekatherms per day of firm transportation service to Calpine Energy Services LP (CES). CES would use this firm transportation service to supply natural gas fuel to its Garrison Energy Center, a 309-MW facility currently being constructed. The project would consist of the installation of the following facilities:

  • approximately 7.2 miles of 16-inch-diameter pipeline looping (in two segments: Daleville and Kemblesville), and appurtenant facilities in Chester County, Pennsylvania; and
  • an additional 3,550 horsepower of additional compression at Eastern Shore’s existing Delaware City Compressor Station in New Castle County, Delaware.

Garrison Energy Center LLC, which has this gas-fired power project that is due for a commercial operations start in mid 2015, filed on Dec. 30 at FERC 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.

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.
