West Virginia regulators approved Moundsville Power LLC's plans to increase the capacity of its planned combined-cycle natural gas plant to 673 MW.
The Public Service Commission of West Virginia on Dec. 19 approved a 124-MW uprate of the company's initial plans to construct and operate the 549-MW natural gas-fired Moundsville Power Project in Marshall County, W.Va.
The PSC in February 2015 issued an order granting Moundsville Power a siting certificate to construct and operate the natural gas plant and associated transmission and interconnection facilities. The combined-cycle plant will be built on a 37-acre site in Marshall County and will interconnect with the PJM Interconnection LLC's grid via a 500-foot, 138-kV transmission line.
"The Commission concludes that a proposed modification to increase the nominal generating capacity of the Moundsville Power LLC electric generating facility from 549 MW to 673 MW is not a material modification and therefore will grant the requested waiver, subject to certain conditions," the PSC wrote in its Dec. 19 order. The PSC said Moundsville Power must meet the conditions outlined in the original approval, which includes the requirement to obtain air quality permit approval from the West Virginia Department of Environmental Protection's Division of Air Quality.
Moundsville Power told state regulators that its generation increase is tied to reliability improvements and upgrades that American Electric Power Co. Inc. plans to make to the surrounding transmission system and George Washington substation.
"The reliability improvements and 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," the company said in its regulatory filings, noting that the upgrades will not change the overall design of the project.
