PJM files revised deal for gas-fired Mattawoman project in Maryland

PJM Interconnection on June 25 filed with the Federal Energy Regulatory Commission a revision of an executed interconnection service agreement (ISA) with Mattawoman Energy LLC and transmission owner Potomac Electric Power that supersedes the ISA that the commission accepted on May 7.

The Mattawoman ISA facilitates the interconnection to the PJM transmission system of 894 MW (Maximum Facility Output) at the Mattawoman Energy Facility located on Brandywine Road in Prince George’s County, Maryland. The Mattawoman ISA indicates that Mattawoman shall have Capacity Interconnection Rights at the Point(s) of Interconnection specified in the Mattawoman ISA in the amount of 744 MW, and Incremental Auction Revenue Rights in quantities to be determined pursuant to the timeframes and procedures set forth in Section 231 of the PJM Tariff.

This is a natural gas-fueled combined-cycle facility arranged in a two combustion turbine and one steam turbine (2X1) configuration. Under this new ISA, on or before May 1, 2018, Mattawoman Energy must demonstrate commercial operation of all generating units. That is the same deadline as the older ISA.

A company contact is: Mattawoman Energy LLC, 5001 Spring Valley Road, Suite 1150, West Dallas, TX 75244, Attn: Mr. John Boswell.

There has been other activity lately on this project:

  • Dominion Transmission Inc. (DTI) applied May 15 with FERC for a Certificate of Public Convenience and Necessity on a series of gas transmission projects that would provide natural gas to two planned power plants in the Washington DC area, including Mattawoman. This certificate would authorize DTI to construct, install, own, operate and maintain certain facilities located in Clinton, Franklin, and Centre counties, Pa.; Frederick County, Maryland; and Loudoun and Fauquier counties, Virginia. This Leidy South Project will provide firm transportation service of 155,000 dekatherms per day (Dt/d) from the Leidy Interconnect in Clinton, Pa., to points in Loudoun, Va. The project customers, who have entered into binding precedent agreements for all of this capacity, are: Panda Stonewall LLC, Virginia Power Services Energy and Mattawoman Energy LLC.
  • The Maryland Public Service Commission is reviewing a July 2013 application for this project, with the commission planning a July 21 local public hearing and a possible decision this fall.
