Moundsville Power nears West Virginia PSC decision on project changes

Moundsville Power LLC on Dec. 15 filed with the West Virginia Public Service Commission a proposed order that, if approved by the commissioners, would allow several changes for its gas-fired power project, including a capacity uprate.

The proposed order has been reviewed and approved by Moundsville Power, commission staff and the West Virginia State Building and Construction Trades Council, AFL-CIO. It has not been reviewed and approved by the petitioner for special intervention, the Ohio Valley Jobs Alliance.

The proposed modifications include an increase in Moundsville Power’s nominal generating capacity of 549 MW to 673 MW. The proposed order says this increase of 124 MW in net generating capacity of the gacility is not a material modification to Moundsville Power’s siting certificate.

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. The approval also covered an approximately 500-foot, 138-kV (less than 200,000 volts) transmission support line, and associated interconnection facilities.

In August 2016, Moundsville Power filed this 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. Moundsville Power 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 138-kV interconnection line. The reliability improvements will allow Moundsville Power to increase the electrical generation from the facility and transfer the increased generation to the adjacent George Washington substation, allowing Moundsville Power to operate at its full design potential.

The proposed order noted: “Moundsville Power stated that the electrical generation process and overall design of the Project have not changed from the Application. Moundsville Power is continuing to use the same [General Electric] equipment with two GE 7FA.04 equivalent gas turbines and a GE D11 steam turbine; the locations of the gas turbines, steam turbine, exhaust stacks and cooling tower will not materially change; no additional generating units are being added to the Facility; and the perimeter footprint (including the transmission line) will not change.

“Moundsville Power explained that it presently has an Interconnection Services Agreement with PJM for 545 MW and is proceeding through the interconnection process with PJM to further increase the Facility’s capacity.”
