NERC's New Winter Reliability Assessment Raises Concerns for Elevated Risk of Insufficient Supplies to Meet Demand in Extreme Operating Conditions

LCG, November 19, 2025--NERC yesterday released its 2025–2026 Winter Reliability Assessment (WRA), which concludes "much of North America is again at an elevated risk of having insufficient energy supplies to meet demand in extreme operating conditions."

NRG Energy Sells Generation Assets for $138 Million

LCG, December 3, 2015-NRG Energy Inc. announced yesterday that it has agreed to sell two of its generating stations: the 525 MW Seward power plant in New Florence, Pennsylvania and the 352 MW Shelby County power plant in Neoga, Illinois. The two transactions, with a combined purchase price of $138 million, are expected to close in the first quarter of 2016, subject to regulatory approvals.

NRG's CEO stated, "NRG is focused on maintaining a robust presence and balance through conventional generation assets that complement each other in respect to geography, technology and smart fuel diversity. By streamlining our fleet, we can create additional value for our shareholders and meet the needs of our customers with reliable, efficient and economic power. This is part of our ongoing and deliberate strategy of portfolio optimization."

The Seward facility is located in the PJM Interconnection and burns waste coal using a Circulating Fluidized Bed (CFB) boiler design. The Seward plant became operational in 2004 and is built on the site of an old coal-fired plant that was demolished in 2003. The facility will be acquired by Seward Generation, LLC, a Robindale Energy Services, Inc. company. NRG Energy Services will provide operations and maintenance services to the Seward plant on behalf of Robindale Energy using the current NRG workforce.

The Shelby County facility is located in the MISO Interconnection and is a natural gas-fueled, simple-cycle combustion turbine peaking plant with eight General Electric LM6000 aero-derivative combustion units. The plant will be acquired by an affiliate of Rockland Capital, LLC.

NRG's COO stated, "Operating a diverse generation fleet is a key component of NRG's continued success in every region in which we operate. As part of our asset optimization initiative, we've identified a few specific facilities that would be better suited in other hands in markets where we can transact at good value while avoiding future capital expenditures."
