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.

Bankrupt NRG's Plants Seen as Important to Reliability

LCG, July 18, 2003--NRG Energy, the bankrupt merchant developer, says that its losses from operating power plants under a supply contract with Connecticut Light & Power amount to $500,000 per day, and that it could have no cash left within less than a month with which to continue running the plants.

In a ruling in June, the Federal Energy Regulatory Commission (FERC) determined that NRG must honor its supply contract, which is scheduled to end at the end of the year. The grid administrator for New England, ISO-NE, has warned that the risks of not having enough power to supply customers in Connecticut would increase substantially during peak periods if capacity goes offline for any reason. NRG Energy has 25 generating units that have a combined potential output of 2,155 megawatts.

According to the New England Independent System Operator, areas throughout its territory would be vulnerable to blackouts in the absence of NRG's resources. It has urged FERC to "take whatever actions are necessary" to see that NRG's plants do not cease to operate.
