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.

CAISO Finds Duke Did Not Withhold Power
LCG, Oct. 28, 2001--An analysis of generators' available capacity during May 8, 2001, a day on which rolling blackouts were ordered in California, has found that while earlier California Public Utilities Commission (CPUC) conclusions concerning generators' withholding of power were substantially correct, Duke Energy did not withhold capacity on that day.The California Independent System Operator (ISO) issued a report Friday in response to a request from state Sen. Joe Dunn (D-Santa Ana), who is investigating last year's energy crisis. The grid operator said that outage data provided by the ISO, which was used as the basis for a report last month by the CPUC, may have led the commission to make conclusions about specific generators' reasons for outages which may or may not be correct. The ISO stated in its report that Unit 3 of Duke's Morrow Bay plant was on scheduled outage on May 8, 2001, and that the ISO had asked some of Duke's other generators to reduce output, meaning no remaining capacity was available from the company.According to the ISO, generators did have power available that was not bid into the market and were not always responsive to the grid operators' emergency orders. These behaviors did contribute to a difficult situation when the ISO required power in particular areas, according to its report. The ISO said however, that in discussing the usage of its outage data with the CPUC that the commission "may have used outage data that was useful for depicting outages on a macro level but which was not appropriate for investigation of unit-specific behavior during a specific subset of hours."Among the considerations that the ISO said were not explicitly accounted for in the earlier CPUC report were generating units' ability to increase output at a certain rate, the units' actual capacity as opposed to their rated capacities, and the need to have units back down their output to provide more power later if necessary. Transmission constraints and ISO's need to maintain stable conditions on the grid were also cited by the ISO as not appearing in the CPUC findings.
