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.

Hydro Pumped Storage - DOE Award to Support Development of Advanced Water Power Technologies



- Hydropower Grid Services to maximize the benefits of hydropower technologies

LCG, August 9, 2010 -- A consortium headed by Electric Power Research Institute (EPRI) has been selected by the Department of Energy to develop new methods to quantify and maximize the benefits that conventional hydropower and pumped storage hydropower provide to transmission grids. For a period of two years, DOE will provide up to $1.5 million for this effort.

LCG as a member of the consortium will assist EPRI to develop and demonstrate an innovative approach using UPLAN, an industry-proven modeling tool, at the unit level, the plant level, the system level, and the regional/national level, over multiple time scales ranging from hours to years in order to quantify and maximize the benefits provided by conventional and pumped storage hydroelectric projects to transmission grids.

Because of the large role hydro plays in the West, the anticipated increase in renewable portfolio in the West aided by California’s postulated 33% renewable portfolio standard (RPS) by 2020 and the proposed carbon trade policy, the team has selected the Western Electricity Coordinating Council (WECC) as the region of study.

“LCG will simulate the WECC electricity system using its proprietary UPLAN model and the hybrid WECC-California database for the study years 2010 through 2020. Our primary objective is to develop a realistic WECC model to demonstrate how existing and new conventional and pumped storage hydro can bring benefits to the grid to meet the proposed RPS requirements in the West,” said Sidart Deb, Vice President of Operations at LCG.
