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.

EPA Issues Final MATS Rule
LCG, April 3, 2013--The Environmental Protection Agency (EPA) on March 29 issued the final rule for the Mercury and Air Toxics Standards (MATS) for new coal- and oil-fired power plants, setting mercury limits slightly higher than the previous rule set in December 2011.
The EPA's action revises certain new source numerical limits in the MATS National Emission Standards for Hazardous Air Pollutants (NESHAP). Specifically, the EPA is finalizing revised hydrogen chloride (HCl), filterable particulate matter (fPM), sulfur dioxide (SO2), lead (Pb), and selenium emission limits for all new coal-fired electric generating units (EGUs); the mercury (Hg) emission limit for the "unit designed for coal > 8,300 Btu/lb subcategory;" fPM and SO2 emission limits for new solid oil-derived fuel-fired EGUs; fPM emission limits for new continental liquid oil-fired EGUs; and most of the emission limits for new integrated gasification combined cycle (IGCC) units.
The final rule sets the limit for mercury emissions for units not designed for low rank virgin coal at 0.003 pounds/GWh, which is slightly higher than the initial rule. Mercury emissions for units designed for low rank virgin coal were not opened for reconsideration.
With respect to fPM, emission limits from all new coal-fired power plants are set to 0.09 pound/MWh, and HCl emission limits are set to 0.01 pound/MWh.
The EPA stated, "Our analysis shows that new EGUs would choose to install and operate the same or similar air pollution control technologies in order to meet the revised emission limits as would have been necessary to meet the previously finalized standards. We project that this final action will result in no significant change in costs, emission reductions, or benefits. Even if there were changes in costs for these EGUs, such changes would likely be small relative to both the overall costs of the individual projects and the overall costs and benefits of the final rule. Further, we believe that EGUs would put on the same controls for this final action that they would have for the original final MATS rule, so there should not be any incremental costs related to this revision."
