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.

Conversion of Coal-fired Plant Near Completion

LCG, Apr. 21, 2003--The shutdown of the coal-burning part of the Noblesville power plant in Indiana in late February will be followed in June by the start-up of three new gas-fired combustion turbines, according to Cinergy Corp.

The plant was rated at 90 megawatts previously, and with the operation of the gas turbines, will have a nominal capacity of 300 megawatts. The turbines from the coal plant will be run by steam created by the new turbines. Emissions will be reduced by 94 percent, PSI Energy Inc., the Cinergy subsidiary responsible for the conversion, said.

The same firm that designed the original NOblesville plant, Sargent & Lundy, has also done the engineering work for the current installation. It is thought that the facility will produce power for about half the year, for peak demand. The increased efficiency and reduced emissions may aid PSI Energy in reaching a final agreement with the Environmental Protection Agency over emission limits to accompany capacity expansion. Hamilton County will benefit from the new turbines, as its reserve margin has been as low as 1 percent in the past few years.
