FAIRMONT, W. Va., Nov. 11, 2016 /PRNewswire/ -- FirstEnergy Corp. (NYSE: FE) subsidiary Mon Power today announced it has initiated a review of its ownership stake in the Bath County Pumped Storage Project located in Warm Springs, Virginia. The review is driven by recent changes in the PJM capacity market which in the future are expected to reduce sharply Mon Power's capacity revenues from the facility. There is no assurance that this review by Mon Power will result in any alternatives being announced or consummated. Mon Power has an indirect 487-megawatt (MW) ownership interest in the pumped storage hydroelectric generating station which consists of two large reservoirs and a powerhouse interconnected by tunnels. Virginia Electric and Power Company, a subsidiary of Dominion Resources, Inc., is the majority owner of the station and manages its operation. PJM's new capacity rule reduces the value of pumped storage generation stations because they cannot produce electricity continuously during all hours of the day. Under the new rules, Bath's capacity revenues for Mon Power will be reduced by about half. PJM is the regional transmission operator that operates a competitive wholesale electricity market and manages the electric transmission grid in all or parts of 13 states and the District of Columbia to help ensure reliability for more than 61 million people. Capacity is the commitment of generation or other resources to be available to provide electricity in the future, particularly when demand surges during extreme cold snaps or heat waves.
