NuScale Power Achieves Standard Design Approval from NRC for 77 MW SMR

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.

EIA Presents Analysis of California's Solar and Wind Power Curtailment Challenges

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.

Two Plants Seen Ready for June

LCG, Apr. 25, 2002--Two 550-megawatt, gas-fired power plants are seen as being ready to operate starting in June, according to developer Kinder Morgan.

Williams Cos. will provide natural gas to a plant being developed in Jackson, Mich., and will buy the plant's entire output as part of a tolling agreement with Kinder Morgan. The plant is owned by financial services firm CIT, which is part of Tyco International. The plant is expected to be operating at the end of June.

The other plant is sited near Little Rock, Ark., and will be owned and operated by Mirant Corp., which will provide natural gas and sell the plant's output. The Arkansas-based plant is expected to begin operations on June 1.

Both plants will utilize a design that is meant to achieve the fuel efficiency of a combined-cycle power plant, and the quick start-up times of a simple-cycle peaking plant. Combined-cycle plants capture the waste heat from burning fuel in order to heat steam to provide additional energy to drive a turbine, whereas waste heat is otherwise dispersed without contributing to power generation. A simple-cycle peaking plant is an internal combustion engine that can achieve maximum output in less time than a steam turbine or traditional combined-cycle configuration.
