FERC accepts revised interconnect deal for Panda’s Mattawoman project in Maryland

The Federal Energy Regulatory Commission on Aug. 4 accepted a June 25 filed by PJM Interconnection of a revised Interconnection Service Agreement (ISA) among PJM, Mattawoman Energy LLC and transmission owner Potomac Electric Power Co. 

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: John Boswell.

The Maryland Public Service Commission plans an Aug. 17 public hearing in Brandywine, Maryland, over a July 2013 application from Mattawoman Energy LLC for this project, located in Prince George’s County, Maryland, near Washington DC. Mattawoman Energy, a project affiliate of Panda Power Funds, a few months ago offered a major revamp of the project, including a higher power output capacity, which has basically put this review process into overtime. The commission may be able to rule on the project on or around Sept. 30.

Said a July 2 report filed with the PSC by the company in this case: “Mattawoman Energy, LLC (Mattawoman Energy) is proposing to develop, construct, and operate a 990 megawatt (MW) natural gas-fired, combined-cycle power generating facility in southern Prince George’s County, Maryland. In addition to the power plant facility, which will be located on a 90-acre site, the project also requires construction of an approximately 10-mile long reclaimed water pipeline, an approximately 7-mile long natural gas pipeline, a 2.3-mile long electric generator lead line, and a substation.”
