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.

California ISO Declares a Stage 3 Alert – No Outages Yet

LCG, Jan. 16, 2001The California Independent System Operator, still struggling to come up with enough power to meet a forecast demand of 32,315 megawatts in its control area, declared a Stage 3 Electricity Emergency at 7:20 this morning, pacific time.

The ISO said that a total of 10,700 megawatts of generation was off line because of planned maintenance or forced outages. The 1,190 megawatt San Onofre Unit 3 nuclear power plant was among that, having shut down for refueling. Another 1,600 megawatts worth of generation tripped off line over the weekend when something broke.

On the best day in spring, with all plants operating and the state's rivers in full flow, Cal-ISO would have a little more than 44,000 megawatts of power at its disposal. That is a far cry from the 53,000 megawatts of generating capacity some state officials say the state has.

The discrepancy is the one that accompanies comparisons of apples with oranges. Cal-ISO is responsible only for that portion of the transmission network owned by the state's three investor-owned utilities. The ISO can draw on the power generated only by plants owned by those utilities or the ones sold by them to independent power producers.

The state officials, on the other hand, look at total in-state generation, which includes power generated in plants owned by municipal utilities, irrigation districts and rural electric cooperatives. The last time we looked, the Los Angeles Department of Water and Power, a municipal utility, owned about 6,500 megawatts of capacity.

Today, about 33,000 megawatts are available to Cal-ISO, and Cal-ISO is going to need all of it.
