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.

Dominion Plans on Offshore Wind Projects, Pumped Storage and Relicensing of Nuclear Plants to Reduce Carbon Emissions
LCG, August 1, 2019--Dominion Energy presented plans to invest in clean energy infrastructure in its second-quarter earnings call yesterday. Dominion's five-year growth capital plan totals $26 billion through 2023.
A significant portion of Dominion's capital expenditure plan is to develop and install offshore wind projects. In July Dominion initiated construction on its $300 million, 12-MW Coastal Virginia wind pilot project, located 27 miles offshore of Virginia Beach, Virginia. The project is scheduled for completion in 2020. Dominion now expects the offshore lease area may accommodate over 2,000 MW of generation capacity and a total investment of $1.1 billion through 2024.
The executive vice president, president and CEO of Dominion's Power Generation Group stated, "In Virginia, we're looking at the need to get the life-cycle cost equivalent down closer to maybe the $80/MWh range, which means we need to see about a 15% to 20% capital cost improvement. We think that those costs can move in that direction once we stand up the US supply chain. That's been a real benefit that they've seen in Europe is being able to scale up the supply chain."
Given Dominion's interest to add variable or intermittent renewable generation resources, Dominion is also refining its search for a potential site to install a $2 billion to $3 billion pumped storage facility in southwestern Virginia. In addition, Dominion Energy Virginia (Virginia Electric and Power Company) will file its first battery pilot program this week. "We will pair batteries with solar facilities to begin the integration of peak shifting and clipping as well as test the reliability benefits of batteries on our distribution grid."
Relicensing Dominion's four existing Westinghouse pressurized water reactors reactors in Virginia for another 20 years is another critical element of Dominion's plan to utilize carbon-free electric generating resources. The nuclear resources include the approximately 1,958-MW North Anna and the 1,750-MW Surry nuclear power plants, along with a $4 billion capital program. The North Anna and Surry units were originally licensed to operate for 40 years, like all U.S nuclear units. All four units' licenses were renewed for 20 additional years of operation in 2003. The North Anna and Surry nuclear units' respective licenses currently will expire in 2038 and 2040, and 2032 and 2033. After a second renewal, the respective licenses for North Anna and Surry will allow the units to operate to 2058 and 2060, and 2052 and 2053.
