The West Virginia Public Service Commission in a Dec. 19 order concluded that a proposed modification to increase the nominal generating capacity of Moundsville Power LLC’s gas-fired project from 549 MW to 673 MW is not a material modification and therefore granted a requested waiver, subject to certain conditions.
In February 2015, the commission granted Moundsville Power a siting certificate for the construction and operation of a combined cycle natural gas-fired wholesale generating facility of approximately 549 MW in Marshall County, together with an approximately 500-foot 138-kV (less than 200,000 volts) related transmission support line.
On Aug. 5, 2016, Moundsville Power filed an application for a waiver of siting certificate modification requirements, or in the alternative, for modification of siting certificate and related requests for relief. Moundsville Power proposed an increase in generation of approximately 124 MW of nominal capacity to the facility. The developer explained that American Electric Power (AEP) intends to make reliability improvements to the surrounding transmission system and upgrades to its George Washington substation, which is the termination point of the project’s interconnection line. The reliability upgrades will allow Moundsville Power to increase the electrical generation from the facility and transfer the increased generation to the adjacent George Washington substation for insertion into the electrical grid, allowing Moundsville Power to operate at its full design potential.
Moundsville Power stated that the electrical generation process and overall design of the project have not changed from the original application. Moundsville Power is continuing to use the same General Electric (GE) equipment with two GE 7FA.04 equivalent gas turbines and a GE D11 steam turbine.
Moundsville Power explained that it presently has an Interconnection Services Agreement with PJM Interconnection for 545 MW and is proceeding through the interconnection process with PJM to further increase the facility’s capacity.
Said the Dec. 19 order: “Based on the entire record and the analysis contained in this Order, the Commission concludes that the proposed increase of 124 MW in net generating capacity of the Facility does not constitute a material modification of the Siting Certificate, and the Commission therefore grants Moundsville Power’s requested waiver, subject to the conditions adopted in the Siting Certificate Order, including an appropriate air permit issued by [the West Virginia Division of Air Quality] in accordance with the Clean Air Act and the West Virginia State Implementation Act, and further subject to all other ordering paragraphs in the Siting Certificate Order.”
