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.

New York PSC Directs RG&E to Contract for Power from R.E. Ginna Nuclear Power Plant

LCG, November 17, 2014-The New York Public Service (PSC) ordered Rochester Gas & Electric (RG&E) to negotiate a power purchase agreement (PPA) for electricity generated from the R.E. Ginna Nuclear Power Plant, which is owned by Constellation Nuclear Energy Group, a subsidiary of Chicago-based Exelon.

Constellation had petitioned for assistance from the PSC, stating that it had lost $100 million over the last three years and that it has forecast revenue shortfalls after the contract with RG&E expired at the end of last June. Exelon stated to the PSC, "Projected market revenues are insufficient to support the Ginna facility's continued operation."

Under the expired contract, RG&E purchased 90 percent of the power generated from the 581-MW nuclear power plant. After the expiration, Constellation has to accept competitive market prices. With relatively low natural gas prices and low market prices for electricity, the non-carbon emitting nuclear facility could be uneconomic to run, which could then lead to the closure of the facility. Based on a study released last month, closure of the base load, 44-year old nuclear facility, located 22 miles northeast of Rochester, could increase grid reliability risks.

The PSC stated that, with its order, it is acting to protect grid. The Chair of the PSC would like to develop a solution to maintain grid reliability until an alternative can be implemented.
