LCG, December 1, 2025--The Nuclear Regulatory Commission (NRC) announced today that the NRC staff completed its final safety evaluation for the application submitted by TerraPower, on behalf of its subsidiary US SFR Owner, to construct the Kemmerer Power Station Unit 1 in Kemmerer, Wyoming. Unit 1 will be the first nuclear project of its kind using the Natrium advanced reactor design. The evaluation concludes there are no safety aspects that would preclude issuing the construction permit.

LCG, November 26, 2025--RWE announced today the commissioning of the Stoneridge Solar project, located in Milam County, Texas. The project capacity is 200 MW of solar power, plus a battery energy storage system (BESS) that provides 100 MW (200 MWh) of battery storage capacity. The BESS improves the supply of short-term, reliable, affordable electricity in ERCOT.

PJM Capacity Rules Drive Mon Power to Evaluate Options for Bath County Pumped Storage Project
LCG, November 16, 2016--FirstEnergy Corp. subsidiary Mon Power Friday announced that it has initiated a review of its ownership stake in the Bath County Pumped Storage Project located in Warm Springs, Virginia. Mon Power's review is driven by recent changes in the PJM capacity market that are expected to reduce sharply its capacity revenues from the facility.
Mon Power has an indirect ownership interest in the pumped storage hydroelectric generating facility that includes a higher and lower reservoir and a powerhouse interconnected by tunnels. The powerhouse includes six pump-turbines that (i) generate power when water flows from the higher to the lower reservoir (and hourly power prices are relatively high) and (ii) consume power to pump water from the lower to upper reservoir (when power prices are relatively low, e.g., at night). Dominion Resources, Inc. subsidiary Virginia Electric and Power Company is the majority owner and operator of the facility, which has a total generating capacity of approximately 3,000 MW.
The new capacity rule for PJM, the regional transmission operator, is expected to reduce the value of pumped storage generation stations because they cannot produce electricity continuously during all hours of the day. Mon Power estimates that, under the new rules, its capacity revenues from Bath County will be roughly cut in half.
First Energy Corp. sold a number of hydro facilities in 2014, when it completed the sale of 11 other hydroelectric power stations to Harbor Hydro Holdings, LLC, a subsidiary of LS Power Equity Partners II, LP. The total capacity of those hydroelectric facilities was 527 MW, including the Seneca Pumped Storage Hydro Plant (451 MW), located in northwestern Pennsylvania.
