LCG, May 30, 2025--NuScale Power Corporation (NuScale), a leading provider of advanced small modular reactor (SMR) nuclear technology, yesterday announced that it has received design approval from the U.S. Nuclear Regulatory Commission (NRC) for its uprated 77 MW power modules. NuScale states that it remains the only SMR technology company with design approval from the NRC, and the company remains on track for deployment by 2030, with 50- and 77-MW SMR options.

LCG, May 29, 2025--The U.S. Energy Information Administration (EIA) released an analysis yesterday showing that the California Independent System Operator (CAISO), the grid operator for most of the state, is increasing its curtailment of the rapidly growing solar- and wind-powered generation facilities in order to balance electricity supply and demand, which is necessary to maintain a stable electric system.

Repowered Colorado Nuke Provides 720 Megawatts
LCG, June 13, 2001Xcel Energy Inc. said yesterday that its Public Service Co. of Colorado subsidiary's conversion of the decommissioned Fort St. Vrain nuclear power plant to operate on natural gas has been completed and the facility is producing 720 megawatts of much-needed power.Fort St. Vrain was a 366 megawatt high temperature, gas-cooled reactor completed in 1979. The unusual design almost all U.S. commercial reactors are water-cooled was plagued with problems and the plant was permanently shut down in 1989. In 1996, it became the first U.S. nuclear plant to complete decommissioning.But the infrastructure was still there the switchyard, interconnection with the grid and most of all the steam turbine-driven generator. Since decommissioning, three gas-fueled turbine generators of 140 megawatts each have been installed and a heat recovery steam generator that will provide steam to spin the original generator.Public Service Co. will need the power. Since 1990, its customer base has grown 20 percent and the average residential customer is using 12 percent more power. There has been concern that Colorado could suffer a supply problem similar to that which caused California's energy crisis."Our customers want to know whether we'll face the same situation here. I'm pleased to say that we don't expect to, and the fully repowered Fort St. Vrain station is one of the largest reasons why I am so confident," said Cynthia Evans, an Xcel vice president.Fort St. Vrain is expected to provide about 12 percent of Xcel's demand in Colorado, David Wilks,president of energy supply for Xcel, told reporters.
