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.

Southwest Power Pool Sets Wind Penetration Record of 62.13 Percent
LCG, April 4, 2018--Southwest Power Pool (SPP) achieved a record wind penetration and record renewable penetration levels in the early morning on March 31. According to SPP, the wind generation was approximately 14.5 GW, or 62.13 percent, at 1:54 a.m. Combined with nuclear output, the renewable generation resources contributed to about 64.7% of the total load.
With the record setting wind generation, the five-minute SPP North Hub real-time locational marginal prices (LMP) fell to about $2.25/MWh at 1:55 a.m. in the real-time market, while SPP South Hub LMP dropped to negative $10/MWh.
The all-time high wind generation record was set at 15,690 MW in December, serving 51 percent of total load at that time.
The prior wind record was set on March 17, when wind penetration hit as high as 60.56 percent of the total load in the early morning hours. SPP also set a wind penetration record of 58.1 percent earlier in March.
