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.

Out-of-State Bidding Rule Potentially Harmful, CA ISO Says

LCG, May 28, 2003--A rule that allows only real-time energy bids of zero by non-California generators could unnecessarily restrict power supplies during the summer, according to a filing made with the Federal Energy Regulatory Commission by the California Independent System Operator.

The restriction was put in place to avoid the possibility of power being sold out-of-state, potentially leading to higher-cost purchases by California from out-of-state generators. It was to have ended with the introduction of new software to be used by the ISO, with the FERC's approval. Now, the software is expected to arrive later than planned, by fall of this year.

The grid operator still wants generators to be able to bid more than zero, which would allow them to keep from incurring operating costs greater than the market clearing price when their bids are selected. Even if allowed to bid more, those generators would not be able to set the market clearing price. The ISO said in its filing that out-of-state generators' bids into the real-time energy market are reduced from what they had been before the rule was put in place.
