FERC accepts interconnect for 1,038-MW Mattawoman project in Maryland

The Federal Energy Regulatory Commission on Jan. 5 accepted a November 2016 filing by PJM Interconnection of an executed, revised interconnection service agreement (ISA) with Mattawoman Energy LLC and interconnecting transmission owner Potomac Electric Power Co. (PEPCO), plus two executed interconnection construction service agreements with PEPCO and with Virginia Electric and Power Co. (VEPCO).

  • The Mattawoman ISA supersedes the ISA entered into among PJM, Mattawoman and PEPCO that had an effective date of June 1, 2015.
  • The PEPCO ICSA supersedes the ICSA entered into among PJM, Mattawoman and PEPCO, designated as Service Agreement No. 4107, which was reported as conforming in the Electric Quarterly Reports (EQR), effective March 19, 2015.
  • The Virginia Electric ICSA submitted with this filing is designated as Service Agreement No. 4567. 

The Mattawoman ISA facilitates the interconnection to the PJM system of 1,038.1 MW (Maximum Facility Output) at the gas-fired, combined-cycle Mattawoman Energy Facility located on Brandywine Road in Prince George’s County, Maryland. The new Mattawoman ISA modifies the Maximum Facility Output to specify that there is a 144.1 MW increase in the Maximum Facility Output, for a total of 1,038.1 MW.

Under the revised ISA, on or before April 1, 2019, Mattawoman Energy must demonstrate commercial operation of all generating units.

A project contact is: Mattawoman Energy LLC, 5001 Spring Valley Road, Suite 1150, West Dallas, TX 75244, Attn: Michael Trentel, MTrentel@pandafunds.com.

Incidentally, Dominion Cove Point LNG LP (DCP) filed in November 2016 for authorization from FERC to construct, install, own, operate, and maintain certain facilities located in Charles County, Maryland, and Loudoun and Fairfax counties, Virginia, which are needed in part to serve the new Mattawoman plant in Maryland. DCP is a unit of Dominion Resources (NYSE: D). This is called the Eastern Market Access Project. The project would include incremental compression and appurtenant facilities along DCP’s existing transmission pipeline.
