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.

Press Release
The Electric Reliability Council of Texas, Inc. chooses LCG's UPLAN integrated models for generation, transmission, reliability, and investment analysis
LCG Consulting, Los Altos, California, April 23, 2003 – The Electric Reliability Council of Texas, Inc. (ERCOT) has adopted the UPLAN Network Power Model developed by LCG Consulting for their long term projections of the costs of congestion, balancing energy, ancillary services, losses and other factors that are necessary for a realistic economic analysis of long-lived investments such as high voltage transmission lines. ERCOT will also use UPLAN to evaluate the projected costs of Reliability Must-Run Units and Out-of-Merit order services needed to alleviate system constraints in accordance with the market protocols.
ERCOT keeps the lights on in Texas and is one of ten regional reliability councils in North America. ERCOT is home to the largest control area in the United States and oversees the operation of over 77,000 megawatts of generation and 37,000 miles of transmission lines in the state of Texas. The primary regulatory authority for ERCOT is the Public Utility Commission of Texas. ERCOT's members include retail consumers, investor and municipally owned electric utilities, rural electric co-ops, river authorities, independent generators, power marketers and retail electric providers.
UPLAN base case simulation for ERCOT models approximately 500 generators with a total capacity of 74,000 MW using a wide range of generating technologies, 6,000 transmission lines representing 37,000 miles of power grid and 1200 contingencies.
Important factors contributing to ERCOT’s decision include that the UPLAN Network Power Model (UPLAN-NPM) is fully compliant with the newly announced FERC Standard Market Design (SMD) and meets all the functional requirements of Regional Transmission Organization (RTO) proposed in the FERC Order 2000. The model can accurately dispatch generators as well as forecast Locational Marginal Prices (LMP). The UPLAN-NPM is also compliant with the rules in the ERCOT market to solve for zonal balancing energy and congestion management.
