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.

Plug Power Fuel Cells Pass Reliability Milestone

LCG, Nov. 8, 2000--Plug Power Inc. said this morning that its residential fuel cell had passed a key milestone by achieving a "mean time between failure" of more than 1,000 hours. The company is "beta testing" five of the RU1 development units.

That would indicate that half of the failures occur before 41 days have elapsed and half of them occur after 41 days.

According to Greg Silvestri, chief operating officer, Plug Power had a busy and productive summer. "We achieved significant milestones in system testing and reliability and built initial development units of our first commercial product design," he said.

That first commercial product, the RU1, is a 60-Hertz unit that produces power indistinguishable from that supplied by a utility. The units convert natural gas into hydrogen-rich fuel that is passed through the system's fuel cell stack where electricity is electrochemically generated. The fuel cell's power conditioner then converts the electricity into high-quality alternating current for normal household use.

During the summer, the company built 30 fuel cell systems, bringing the total to 91 systems builtso far this year. During the fourth quarter, the company will manufacture the initial prototype RU1 units, one of which is expected to be on display by GE Fuel Cell Systems in the GE Power Systems booth at PowerGen International next week.
