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.

FERC to Review New Filings for Market-Based Rates
LCG, August 10, 2004--Last month, the Federal Energy Regulatory Commission (FERC) issued its Order on Rehearing that confirmed and clarified the new methodology to assess generation market power. For American Electric Power (AEP), Southern Company, and Entergy Corp., yesterday was the deadline to file the market power analysis using the new rules. AEP indicates that the company passes both market screens in the control areas to which AEP is directly connected, while Southern and Entergy both stated in filings that they will fail portions of the new test.In the Order on Rehearing, the FERC stated, "Market-based rate authority is not a right. The Commission may grant such authority under the FPA only to applicants who demonstrably lack market power." Now the FERC must review the filings and determine how to proceed. At risk is the ability of each utility to sell wholesale electricity at market-based rates, rather than the incremental cost of generation.The two screening tests analyze a market participant's total amount of uncommitted capacity available for wholesale sales in a market. The first screen is the pivotal supplier analysis, which examines a participant's generation market power during the peak hour of the year, and is based on a control areas annual peak demand. The hours leading up to that point are the most likely time that a participant will be a pivotal supplier.The second screen is the wholesale market share analysis that examines the market share of a participant in all seasons. Both screens consider native load obligations, operating reserve requirements and other commitments of the participant's. If applicants pass both indicative screens, it is presumed that generation market power does not exist.If the participant fails either screen, it is presumed that the generation market power exists, and the participant can then rebut the presumption with additional analyses. Alternatively, a participant may accept the presumption of market power and go directly to mitigation or inform the FERC it will adopt the default cost-base rates or propose other cost-base rates.
