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.

Abengoa Moves Forward with Large-Scale Solar CSP

LCG, December 19, 2012--Abengoa announced last Friday the inauguration of the 100-MW, Castilla-La Mancha Solar Complex in Spain. The project employs a concentrating solar power (CSP) design.

The Castilla-La Mancha Solar Complex is comprised of two, 50-MW parabolic trough plants. The trough collectors track the movement of the sun across the sky and focus solar energy onto a tube circulating a synthetic heat transfer oil. The oil is heated to approximately 400 degrees C (752 F) and used to generate superheated, high pressure steam that is delivered to a steam turbine to drive an electrical generator, which creates electricity.

In the summer of 2013, Abengoa is also scheduled to commence operations of a larger solar CSP project in Arizona, about 70 miles southwest of Phoenix. The Solana project is designed with a generating capacity of 280 MW. The design also provides for six hours of molten salt thermal energy storage to allow energy to be dispatched as needed, even given cloudy periods and after sunset, when customer summer peak demands for air conditioning can occur. Construction began two years ago, and the project is now over 80 percent complete.
