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.

California ISO Explains Wholesale Market Proposal

LCG, Feb. 6, 2002--Members of California's Senate Energy Committee heard from ISO officials on a wholesale energy market proposal, which is to be submitted to the Federal Energy Regulatory Commission by March.

Lawmakers want new procedures to be in place by the time wholesale price caps end in September. The hearings brought attention to the difficulty ISO has experienced in including all stakeholders in the rule-making process. A former chief operating officer of the ISO, Kellan Fluckiger, said "it's been pointed out that the ISO, while conducting a stakeholder process, is working in a vacuum."

The hearings focused on what consequences would occur when generators did not respond to emergency dispatch orders, or did not deliver power as scheduled. The ISO has charged such generators who do not provide replacement power on their own for the cost of replacement energy. In the last year, the combination of penalties and replacement power that were obtained "wasn't sufficient," said Fluckiger. The proposal outlined for the committee would enable the ISO to impose fines at hours besides just those when price caps are in effect. Sen. Joe Dunn, D-Santa Ana was skeptical of the effectiveness of the rules, saying he had "no confidence that the ISO will enforce the rules."

The ISO also wants to mandate that utilities procure a 15 percent energy reserve. Furthermore, it would try to shift more power purchase transactions to the day-ahead market, as opposed to the hour-ahead and spot markets, for which the ISO is responsible.
