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.

EIA Releases Study on Drought Effects on California Electricity Generation and Power Market using UPLAN Model
LCG, June 6, 2022 – California is experiencing more frequent and intense drought conditions. One effect of droughts is the reduction in hydropower. In its Short-Term Energy Outlook (STEO), the U.S. Energy Information Administration assumes that monthly generation in the future follows average historical patterns to forecast California's hydroelectric generation. However, cyclic drought conditions demand an alternative approach to modeling hydropower, with more hydrological variables included to account for highly variable hydro conditions. Growth in intermittent generating capacity also magnifies the impact of droughts on power markets. In light of this, EIA performed this study as a supplement to STEO using LCG Consulting’s UPLAN model.
Six major hydropower projects in California are modeled for the critical summer months from June to September using detailed information about water and reservoir storage conditions. These hydropower projects have the biggest influence on the overall hydroelectric generation in California. EIA examines two cases: a median case assuming median water supply between 1980 and 2020 and a drought case representing the current year.
EIA found in the drought case, California's summer hydroelectric share of generation mix was nearly halved from 15% to 8%, with the reduction in generation offset by electricity from neighboring markets and in-state natural gas generation. Increased natural gas generation contributed to higher electricity prices and CO2 emissions. On-peak prices in Northern California increased by 7% relative to the median case, and Southern California by 5%.
The UPLAN model incorporated natural inflow to each hydropower project with initial reservoir inventory, and EIA used this information to produce forecasts of hourly generation.
