Keys Energy Center seeks FERC approval on Maryland power project

The Federal Energy Regulatory Commission will be taking comment until Aug. 16 on an application by Keys Energy Center LLC related to a gas feeder pipeline needed for its gas-fired power plant project in Prince George’s County, Md.

On July 17, Keys Energy Center filed a petition for declaratory order requesting the commission issue an order stating that Keys’ proposed pipeline, which will consist of one 7.5-mile segment of 20-inch pipe, is non-jurisdictional inlet pipe that is necessary and integral part of its natural gas-fired electricity generating plant, FERC said in a notice to be published in the July 29 Federal Register.

Keys proposes to construct and operate a pipeline wholly located within Maryland for the purpose of delivering its gas from the Dominion Cove Point LNG LP pipeline to Keys’s plant.

Keys, a subsidiary of Genesis Power LLC, is developing a new nominal 735-MW, two-on-one (2×1) combined-cycle, natural gas-fired plant in Prince George‘s County. The proposed Keys Plant will be constructed on a 170- acre parcel of land formerly used for a sand and gravel mining operation.

The Keys Plant will consist of: two combustion turbine generators equipped with dry, low oxides of nitrogen (NOx) combustors; two heat recovery steam generators with duct burners; a single condensing steam turbine generator; a derating surface condenser; a mechanical draft wet cooling tower; a natural gas-fired auxiliary boiler; and associated ancillary equipment. The plant will be interconnected to the Potomac Electric Power transmission line that passes adjacent to the Keys Plant by directly connecting to the 500-kV breaker-and-one-half bus arrangement in the new on-site substation.

Keys has filed for 735 MW of firm capacity under its electrical interconnection request and is PJM Generation Interconnection Request Queue Position X4-035. The System Impact Study Report was issued in November 2012 and the Facility Study Agreement was signed in December 2012.

Keys estimates that its plant and transmission line will be operational in December 2016. In anticipation of that in-service date, Keys requested that the commission to declare that the 7.5-mile Keys Plant Line constitutes a nonjurisdictional plant inlet pipeline that is a necessary and integral part of the Keys Plant.

The site for the Keys Plant is within about two miles of the site of a newly-proposed project of Mattawoman Energy LLC, a project affiliate of Panda Power Funds. Mattawoman Energy applied July 19 at the Maryland Public Service Commission for approval of an 859-MW, gas-fired power project to be located about 12 miles southeast of Washington, D.C., in Prince George’s County.

Power from the Mattawoman facility would move to an existing 230-kV line running along Brandywine Road of Potomac Electric Power. For gas supply, the project would be tapped into the existing Dominion Cove Point gas pipeline.
