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.

FERC Approves Pumped Storage Project in Oregon

LCG, May 2, 2019--The Federal Energy Regulatory Commission (FERC) granted approval and a license Tuesday to construct, operate and maintain the 400-MW Swan Lake Energy Storage Project, located near Klamath Falls, Oregon. The $800 million energy storage project is a joint project between Rye Development and National Grid, which are also in the earlier stages on an even larger, 1,200-MW project on the Washington side of the Columbia River east of Portland.

The proposed Swan Lake Energy Storage Project will provide utility-scaled energy storage capacity to complement the growth of wind farms that intermittently generate electricity within the day throughout the year. The project will pump water from the lower reservoir to the upper reservoir at times when power prices are relatively low. When power prices are high and energy is needed, water will be released from the upper reservoir through the power tunnel to the powerhouse to generate electricity. This will occur based on hourly power prices, the need to augment the production of local renewable wind power generation, or to provide ancillary power services.

The elevation difference between the two, 60-plus-acre reservoirs is over 1,600 feet, which would support an electric generating capacity of approximately 400 MW, together with a duration of up to nine hours.

The project would transmit electricity from the powerhouse via a new, 32.8-mile-long, 230-kV above ground transmission line that would connect to the grid at the Malin Substation.

The project developers are pursuing customers for the energy storage facility, which should be aligned with the needs of utilities in the Northwest that seek rapid growth in renewable resources and reducing or eliminating generation resources that emit carbon dioxide.
