Over two years later, Maryland PSC approves 990-MW Mattawoman project

Because nobody appealed it by a statutory deadline, the Maryland Public Service Commission on Nov. 13 granted a final approval to a tentative decision in a proceeding that had gone for over two years for approval of the gas-fired, 990-MW Mattawoman power project.

Said the brief Nov. 13 final order: “The Proposed Order of Public Utility Law Judge filed in the above-entitled matter on October 13, 2015, was not appealed by any party, nor has the Commission modified or reversed the Proposed Order or initiated further proceedings into this matter. Therefore, today the Proposed Order became a final order of the Commission, and it was assigned Order No. 87243.”

Project company Mattawoman Energy LLC is a project affiliate of Panda Power Funds. Mattawoman Energy filed for a Certificate of Public Convenience and Necessity for this project, at a nominal size of 859 MW, in July 2013. The project has since been uprated to 990 MW, with associated changes causing a delay in the review of the project so that all parties could have input on those changes. The project site is in Prince George’s County, Maryland, about 12 miles southeast of Washington D.C.

The utility law judge noted in the Oct. 13 tentative approval that comments on this project were “strident,” with most comments being against the project, mostly from local residents, but also with many comments filed for the project and the jobs it will create. On Sept. 17, a local community group tried to intervene in the case, but was rejected for filing that request too late in the process.

In other recent developments for this project:

  • PJM Interconnection posted to its website a study, dated September 2015, that is an interim step in the process that Mattawoman Energy is pursuing to get an Interconnection Service Agreement. Mattawoman Energy has proposed a natural gas-fueled combined cycle facility arranged in a two combustion turbine, one steam turbine (2×1) configuration. It will have a total capability of 927 MW with 860 MW of this output being recognized by PJM as capacity. The proposed in-service date is May 1, 2018.
  • Said a July 2 report filed with the Maryland 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.”
