FERC lays out schedule for gas pipelines to serve two Maryland power projects

The Federal Energy Regulatory Commission on April 9 said it should be able to issue a decision by Sept. 3 on gas pipeline applications from Dominion Transmission Inc. that involve gas supply to two gas-fired power plant projects in Maryland.

On Dec. 3, 2014, Dominion Transmission requested Certificate of Public Convenience and Necessity authorizations to construct and operate certain natural gas pipeline facilities. These proposals are known as the St. Charles Transportation and Keys Energy projects, and would allow delivery of: 132,000 dekatherms per day of natural gas to CPV Maryland LLC and its power project; and 107,000 dekatherms per day of natural gas to a new generating station to be constructed by Keys Energy Center LLC.

The commission’s staff will prepare one environmental assessment (EA) for both projects, said FERC in the Aoril 9 notice. This notice identifies the FERC staff’s planned schedule for the completion of the EA. the EA is to be issued on June 5, with a 90-day federal authorization decision deadline of Sept. 3. If a schedule change becomes necessary, additional notice will be provided so that the relevant agencies are kept informed of the project’s progress.

  • The proposed St. Charles Transportation Project consists of installing one new 7,000-horsepower (hp) electric compressor and other above-ground facilities at the existing Pleasant Valley Compressor Station in Fairfax County, Virginia. One new interconnect with CPV would also be constructed, consisting of two new 16-inch diameter taps in Charles County, Maryland.
  • The proposed Keys Energy Project consists of installing one new 6,000-hp electric compressor, as well as piping and equipment at the existing Pleasant Valley Compressor Station in Fairfax County, Virginia. Two new 16-inch diameter taps, a dekatherm building that will house electronic flow control equipment, and a metering and regulating station would also be installed at the Keys Energy Interconnect in Charles County, Maryland.

FERC on April 1 had accepted PJM Interconnection‘s Feb. 4 filing of a replacement Interconnection Service Agreement (ISA) with Keys Energy Center LLC and transmission owner Potomac Electric Power Co. The Keys ISA facilitates the interconnection of the Keys Energy Center, a natural gas-fueled combined cycle project with a Maximum Facility Output (MFO) of 800 MW located on North Keys Road in Prince Georges County, Maryland. The MFO of 800 MW represents an increase of 64.5 MW over the original ISA. PJM noted in the Feb. 4 filing: “The installation and construction of the generating units at the Keys Energy Center has not yet commenced, and the Commercial Operation date is not until June 1, 2017. It also is expected that the full 800 MW of capacity will become operational at the same time, rather than in stages as is often the case with an uprate in capacity.”

In the meantime, several affiliates of Competitive Power Ventures applied March 31 at FERC for approval of a sale of power plant interests to affiliates of Global Infrastructure Management LLC. Among them was CPV Maryland. CPV Maryland is developing and will construct, own and operate a 725-MW (nameplate) combined cycle, gas-fired facility and limited interconnection facilities that will be interconnected with transmission facilities owned by Potomac Electric Power and operated by PJM.
