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.

Tennessee Valley Authority Issues RFP for 200 MW of Renewables
LCG, March 19, 2020--The Tennessee Valley Authority (TVA) issued a request for proposals (RFP) on March 13 to develop up to 200 MW of stand-alone renewable energy resources or renewable energy resources configured with battery energy storage systems (BESS). Solar resources must be tracking, and the projects must be commercially operational and providing power by September 29, 2023 or earlier.
In June 2019, TVA released its final 2019 IRP that provided further direction on how TVA can best deliver clean, reliable and affordable energy in the Valley over the next 20 years. The 2019 IRP recommends a solar expansion between 1,500 and 8,000 MW of solar by 2028 and up to 14,000 MW by 2038.
Proposals to the RFP are due to TVA by April 24, 2020, and the company is expected to announce the selected proposals in the fall of 2020.
Last month, TVA announced the addition of 484 MW of new contracted solar capacity since December. These five new projects resulted from TVA's April 2019 request for proposals for renewable energy projects that can be on line by the end of 2022.
"We are moving to contract large volumes of solar for our customers, whether it's for large business customers through the Green Invest program, or smaller businesses or residential customers who use our Renewable Energy Certificate programs to help offset their carbon footprint," said TVA's vice president of Commercial Energy Solutions. "TVA is pleased to bring renewable options to the table to help reach their sustainability goals."
One project includes 200 MWh (or 50 MW for 4 hours) of battery energy storage, which will make the solar power generated by this installation more efficient and able to be used when it is most valuable to the system.
Four additional projects have been contracted under TVA's new Green Invest program on behalf of large business and industrial customers. The first Green Invest agreement between TVA, Nashville Electric Service, Vanderbilt University, and Silicon Ranch for 35 MW of new solar for the university was announced in January.
"Large-scale solar projects, which cost 75% less than residential rooftop solar, deliver the best value for renewables in the Valley," said TVA's director of Origination and Renewables. "Green Invest is just one of the ways TVA is enabling the growth of large-scale renewable energy projects."
