X-energy Commences First Irradiation Tests of Advanced TRISO-X Nuclear Fuel at Idaho National Laboratory

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.

NextEra Energy and Google Collaborate on Accelerating Nuclear Power Deployment

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.

Quinbrook Receives Federal Approval for the 690-MW Gemini Solar Project

LCG, May 14, 2020--Quinbrook Infrastructure Partners received the Record of Decision on Monday from the Bureau of Land Management (BLM) and the U.S. Department of the Interior for the 690-MW Gemini Solar Project, which will be constructed using 7,100 acres of federal land located approximately 30 miles northeast of Las Vegas, Nevada. The project includes a 380-MW battery energy storage system (BESS) that will enable the solar power to be stored when electric loads are low and to be discharged when load peaks. Quinbrook has a Power Purchase Agreement (PPA) with NV Energy for the Gemini Project output.

The two-phase, Gemini Project will use photovoltaic solar panels and be built over about 28 months, with the first phase commencing operations in early 2021. The final phase could be completed as early as 2022. The estimated cost of the massive solar plus storage project is $1.1 billion, and it is expected to be the largest solar facility in the U.S. when completed. The Gemini Solar Project will be built by Arevia Power.

The Record of Decision received Monday formally concludes the federal authorization and environmental review process for Gemini Solar Project, and it is based on the Final Environmental Impact Statement (EIS) issued in December 2019 under the National Environmental Policy Act (NEPA). The EIS evaluated the potential impact of the physical, cultural and human environments, discussed alternatives and mitigation measures and selected a preferred alternative for the project.

The Co-Founder and Managing Partner of Quinbrook stated, "We are very pleased to have reached a satisfying and final seal of approval from the Department of the Interior and the Bureau of Land Management so that we can now take Gemini forward with confidence. This final decision officially clears the pathway for Quinbrook, and our development partners at Arevia, to accelerate completion of detailed project designs and procurement plans for one of the world's largest renewables projects ever undertaken. Gemini offers the opportunity to showcase, at an unprecedented scale, what we believe to be one of the most promising technological advances in coupling battery storage to utility scale solar power to produce low cost renewable energy over the long term. Gemini will benefit all Nevadans by supporting jobs, stimulating the local economy and capturing the state's abundant solar resources to deliver low-cost, renewable power to NV Energy customers."

The Public Utilities Commission of Nevada (PUCN) granted approval of Quinbrook's 25-year PPA with NV Energy for the Gemini Project in December 2019.
