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.

Cinergy to Spend $700 Million on Smog Control

LCG, Sept. 26, 2000--Cinergy Corp., the Ohio utility that operates some of the coal-fired power plants blamed by states in the Northeast for their air quality problems, said yesterday it plans to spend $700 million on new emissions control equipment.

Principal target of the new equipment will be oxides of nitrogen, the company said. Cinergy believes it can cut NOx emissions, a major cause of smog, by 85 percent to 90 percent.

The plan drew guarded praise from environmentalists. Marilyn Wall, conservation chairwoman of the Sierra Club in Ohio, called the plan "very positive" and said "It sounds like they are stepping up to the plate."

Cinergy said it would install as many as 11 selective catalytic reduction units at some of its power plants to meet new regulatory requirements that begin in 2003. The units, called SCRs, are huge versions of catalytic converters, like those in an automobile exhaust system. They convert NOX to nitrogen, oxygen and water.

Installation has already begun at the East Bend power plant in Rabbit Hash, Ky., Gibson station in Owensville, Ind., and Miami Fort plant in North Bend, Ohio. Future SCR installations are being considered for plants in Cayuga, Ind., and Moscow, Ohio.

Other pollution control equipment is under consideration for plants in New Richmond, Ohio, New Albany, Ind., and West Terre Haute, Ind.

William F. Tyndall, Cinergy's vice president for environmental affairs, said the project will be an "engineering challenge" and one of Cinergy's biggest-ever projects. " We expect to have NOx reduction projects at nearly every coal-fired generating station in the Cinergy system," he added.
