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.

Deterrents to Midwest Manipulation Get Conditional Approval

LCG, Mar 17, 2003--A system created by the Midwest Independent System Operator Inc. to reduce the likelihood of market manipulation has been given conditional approval by the Federal Energy Regulatory Commission.

The proposal would allow adjustment of suppliers' bids downward if they exceeded threshhold levels and raised the market clearing price by the lower of 200% or $100 per megawatt-hour. Local areas would have differing threshhold levels based on the level of congestion and excess of supply relative to demand.

In addition, the Midwest ISO would fine generators if they did not bid into the real-time market and meet minimum operating levels, such that market clearing prices were affected. FERC did not allow a proposal to fine generators for not bidding into the day-ahead market, as there is no mechanism to compensate generators for providing on-line capacity.

The Midwest ISO would not decide on any penalties it imposed. Rather, they would be determined by an independent market monitor. The Midwest ISO and PJM (Pennsylvania-Jersey-Maryland Interconnection) are continuing to develop compatible sets of rules to allow integration of their markets.
