Mattawoman Energy simplifies power plant docket at Maryland PSC

Mattawoman Energy LLC, which wants to build an 859-MW, gas-fired combined-cycle facility in Prince George’s County, Md., on Oct. 24 suggested a new procedural schedule to the Maryland Public Service Commission for the review of this project.

The company initially was seeking a certificate of public convenience and necessity for the power project alone, with a plan for Potomac Electric Power (PEPCO) to after that seek approval for the power interconnection portion of this project to the grid. But the state’s Power Plant Research Program, a routine participant in all power plant proceedings at the commission, objected to the idea of the commission approving the project, then being asked to approve the power line.

So Mattawoman Energy negotiated with parties to the case, including PEPCO and PJM Interconnection, and on Oct. 24 filed a proposed schedule for a combined review of the power plant and the power line. Under this new approach, Mattawoman Energy would construct a generation lead line to an existing PEPCO transmission line located about 2.3 miles north of the power project site. This means that PEPCO would no longer need to file for a separate approval of the originally planned power interconnect and that the power plant and power line can now be considered in one case under Mattawoman Energy.

The proposed new case schedule includes a Jan. 30, 2015, deadline for Mattawoman Energy to file supplemental testimony, and a July 22, 2015, final order target date.

Company representatives on June 30 had provided updates to the Maryland PSC on the status of the project, which has been under consideration for a PSC approval since July of last year. Steven Tessem, the Vice President for Business Development for Panda Power Funds, the parent company of Mattawoman Energy, said the linear facilities being worked on are: the interconnect to the electric transmission system; the water connection with the Piscataway Wastewater Treatment Plant; and the gas lateral connection from the project to Dominion Cove Point LNG LP’s natural gas pipeline.

The project is an 859-MW, two-on-one, combined-cycle facility configured with two Siemens H-class combustion turbines, two heat recovery steam generators with supplemental duct firing, and one steam turbine generator in a multishaft arrangement.
