Oklo and Siemens Energy Sign Agreement to Accelerate Power Conversion System for New SMR in Idaho

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.

NERC's New Winter Reliability Assessment Raises Concerns for Elevated Risk of Insufficient Supplies to Meet Demand in Extreme Operating Conditions

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.

Day-Ahead Market May Be Delayed in California

LCG, Nov. 1, 2002--A Federal Energy Regulatory Commission ruling that a day-ahead market be put in place in January by the California Independent System Operator will not be satisfied, the state grid operator has told the federal agency.

According to the ISO, the timetable imposed by the FERC will create liability exposure and the possibility of a poorly designed set of market rules. The FERC ruled in early October that it would not allow a proposed delay of a day-ahead market for CAISO, until mid-2003. The ISO has run an hour-ahead market, but not a day-ahead market, which was formerly the responsibility of the defunct California Power Exchange.

The FERC believes that generation resources and transmission capacity can be matched more dependably with a day-ahead market. In order to implement the FERC's deadline, the ISO will need to relax restrictions concerning submittals of balanced schedules, which indicate the providers and consumers making up each side of a transaction. "Following the Oct. 11 order, the California ISO has re-examined the feasibility of relaxing the balanced schedule requirement and the market separation rule and conlcuded that it is impossible to do so by Jan. 31, 2003," the grid operator stated.

In expressing the ISO's attitude towards the January deadline, ISO spokesman Gregg Fishman indicated that a more comprehensive, complex set of provisions for the day-ahead and hour-ahead markets the ISO will be required to implement at an as-yet-unspecified date should be its goal, without the ISO's having to rush to an intermediate version before the ISO is ready. "If you are making plans to remodel your entire kitchen in the spring, why are you spending time painting it in the fall," Fishman said.
