Mattawoman makes progress in PJM Interconnection queue process

Mattawoman Energy LLC, which is still working its way through a review process at the Maryland Public Service Commission, is making progress at PJM Interconnection on getting its gas-fired power project a final interconnection service agreement.

A November 2014 Facilities Study from PJM, which is an interim step toward an interconnection agreement, noted that Mattawoman has proposed a natural gas fueled, combined cycle facility arranged in a two combustion turbine, one steam turbine (2×1) configuration to be located in Brandywine, Maryland. The combined generators will have a total capability of 894 MW with 744 MW of this output being recognized by PJM as Capacity.

Mattawoman’s proposed in-service date for this project is May 1, 2018. “While the Pepco construction schedule is supportive of the Interconnection Customer’s commercial operation date, this study report does not imply a Potomac Electric Power Company (Pepco) commitment to that date,” the study noted.

This project, under PJM queue number X3-087, will interconnect with the Pepco transmission system via a generation lead line from the generating facility to a Mattawoman-owned disconnect and breaker placed outside of a new Pepco 230-kV substation. The new Pepco substation will be constructed within, or adjacent to, the existing Pepco right of way between the Burches Hill and Talbert substations.

A review of this project by the Maryland PSC began in July 2013 and is not due to conclude until July 2015. This is a project of Panda Power Funds, which says about the project on its website: “The Panda Mattawoman Power Project is a clean natural gas-fueled, 859-megawatt combined-cycle generating station. Once built, the plant is expected to supply the power needs of up to 859,000 homes and should infuse approximately $1.2 billion into the Maryland economy.” The website said the plant should be substantially complete in 2017.
