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.

PUC Avoids Derailing Big Stone II Coal Project
LCG, October 12, 2007--The Minnesota Public Utilities Commission (PUC) yesterday agreed to allow the application to construct two electric transmission lines from the planned coal-fired unit, Big Stone II, to Granite Falls, Minnesota to proceed. Two of the utilities supporting the new power plant, Great River Energy and Southern Minnesota Municipal Power Agency, recently announced their decision to withdraw from the project, placing the future of the generation and transmission projects in doubt. The five co-owners of Big Stone II are now Otter Tail Power Co., Central Minnesota Municipal Power Agency, Heartland Consumers Power District, Missouri River Energy Services and Montana-Dakota Utilities.
As previously proposed, the transmission project was to extend between 140 and 160 miles and to cost $225 million to $275 million. With the withdrawal of the two utilities, the project partners informed the PUC that the Big Stone II power plant capacity may be reduced from a 630-MW to perhaps a 500-MW or 580-MW plant.
The proposed electric generating facility would be sited adjacent to the existing, 450-MW Big Stone facility located near the Minnesota-South Dakota border.
Opponents of the projects had hoped that, with uncertainty hanging over the power plant and its design capacity, the transmission line project would be sent back to square one to restart the approval process, which would have led to significant delays in the projects.
A final decision from the PUC is anticipated in 2008.
