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.

Cal-PX Halts Market Ops; Going Out of Business

LCG, Jan. 31m 2001--The California Power Exchange said yesterday that it would no longer operate its day-ahead and day-of energy markets. The move is in response to a Federal Energy Regulatory Commission order that it recalculate all transactions made so far this year.

When FERC set its "soft cap" of $150 per megawatt-hour it eliminated a rule that all clearing prices be at the highest price bid and pay only the actual price bid. Cal-PX ignored that portion of the order and requested a stay of the order and a rehearing with the U.S. Ninth Circuit Court of Appeals. The court is scheduled to hear oral arguments on February 7.

"Regrettably, Cal-PX must take this extraordinary action in response to FERC's order that directs us to immediately comply with the terms of its December 15 order and implement a $150 breakpoint," Cal-PX president and chief executive George Cladode said in a statement.

Cal-PX said market participants stopped doing business with the exchange following the FERC order and defaults by Southern California Edison Co. and Pacific Gas & Electric Co. only made matters worse.

"The continuing defaults in our markets and threats of defaults in the next couple of days make it ridiculous to keep the market going when you're a public benefit corporation that's revenue neutral," said Cal-PX spokesman Jesus Arredondo.

The quasi-public agency said it is in the process of winding down operations in order to shut its doors.
