LCG, November 6, 2025--X-energy Reactor Company, LLC, (X-energy) and the U.S. Office of Nuclear Energy today announced the start of confirmatory irradiation testing at Idaho National Laboratory (INL) to qualify X-energy’s proprietary TRISO-X fuel pebbles for commercial use in the Xe-100 Small Modular Reactor (SMR). (TRISO stands for TRi-structural ISOtropic). This is the first time that TRISO-X fuel pebbles will undergo irradiation testing in a U.S. lab, which is a critical step in meeting requirements set forth by the U.S. Nuclear Regulatory Commission (NRC) for the commercial deployment of advanced reactors that will use the fuel.

LCG, October 28, 2025--NextEra Energy and Google yesterday announced two agreements that will help meet growing electricity demand from artificial intelligence (AI) with clean, reliable, 24/7 nuclear power and strengthen the nation's nuclear leadership. First, Google signed a new, 25-year agreement for power generated at the Duane Arnold Energy Center, Iowa's only nuclear power facility. The 601-MW boiling water reactor unit was shut down in 2020 and is expected to commence operations by the first quarter of 2029, pending regulatory approvals to restart the plant.

Connecticut Wrestles with Finding the Right Transmission Solutions
LCG, June 17, 2004--ISO New England stated today that the current design of Northeast Utilities' and United Illuminating's proposed transmission upgrade in Southwest Connecticut would result in a transmission system that continues to have significant reliability issues. ISO New England expressed the need to evaluate alternative transmission designs to ensure a viable solution for the state's and the region's energy needs.The proposed, two-phase upgrade to the Connecticut transmission system includes 345 kV lines in a loop around Southwest Connecticut. Phase I was approved by the Connecticut Siting Council last year, with 12 miles of underground cable. The current hearings address Phase II, which adds 24 miles of underground cable to the transmission loop.
ISO New England Chief Operating Officer Stephen G. Whitley stated in his testimony to the Siting Council that the proposed extensive use of underground cable will not realize the intended reliability benefits, will add costs to Connecticuts customers, and will further delay developing a suitable solution for the state and the region. Whitley requested the Siting Council to enable further study and evaluation of the proposed design and is confident that ISO New Englands concerns do not preclude a solution that could include some portion of underground transmission lines. Whitley said these projects are needed to ensure a reliable supply of power not only for Connecticut but also for all of New England.With respect to reliable supply of power to the region, the Federal Energy Regulatory Commission (FERC) has called today for settlement talks between Connecticut and New York to resolve the dispute regarding the Cross-Sound Cable, which is capable of delivering 330 MW between New Haven, Connecticut and Long Island, New York. The cable was commissioned in 2002 but has seen limited use, as Connecticut says the line violates environmental rules with respect to the depth the Cable, which crosses the Long Island Sound, is buried. New York wants the Cable in use to better ensure reliability and have access to additional supplies. The Cable was brought into service for a period following the August 14, 2003 blackout to assist in bringing the grid back online and improve reliability. "I want the parties to let us know if there is a settlement possible here," FERC Chairman Pat Wood said. The agency will rule on the case on June 24 if no agreement is reached.
