(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.

FERC Finds Much Room for Demand Response

LCG, July 9, 2003--Despite high natural gas prices and resulting increased power prices, staff of the Federal Energy Regulatory Commission have found little evidence of coordinated reduction in demand aimed at heading off price spikes.

Those regions of the country that have experienced the most severe power price increases include Florida, Texas and the West Coast, according to FERC's Office of Market Oversight and Investigations. It stated that FERC has tried to bring rules into effect that would increase the potential benefits of demand response. The areas of the country where demand response has received the most attention are New York, Connecticut, California and Florida.

The Office of Market Oversight and Invesigations' Summer Energy Market Assessment included remarks in the outline that "Demand response, an effective tool for dampening price spikes, is missing from electricity markets."
