LCG, November 19, 2025--Oklo Inc. and Siemens Energy announced today that the parties have signed a binding contract for the design and delivery of the power conversion system for Oklo’s Aurora-INL (Idaho National Laboratory) nuclear small modular reactor (SMR). The agreement authorizes Siemens Energy to begin engineering and design work to expedite procurement of long-lead components and to initiate the manufacturing process for the power conversion system. Oklo’s expertise in advanced fission technology will be combined with Siemens Energy’s extensive industry experience with steam turbine and generator systems, with the ultimate goal of generating carbon-free, reliable electricity.

LCG, November 19, 2025--NERC yesterday released its 2025–2026 Winter Reliability Assessment (WRA), which concludes "much of North America is again at an elevated risk of having insufficient energy supplies to meet demand in extreme operating conditions." The WRA does state that resources are adequate for normal winter peak demand, but extended, wide-area cold snaps will be challenging.

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."
