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.

Puget Energy Says California Caps Affect Us, Too

LCG, Nov. 3, 2000--Puget Sound Energy Corp. has requested federal regulators to uniformly impose price caps on sellers of wholesale electricity in both the California and Pacific Northwest power markets.

Puget Energy said that price caps set only in California without the same applied in the Pacific Northwest would result in California buying Pacific Northwest power at artificially low prices when they needed it and Pacific Northwest customers paying higher costs when the need is reversed.

"Generally, we do not favor price caps since they do not allow a wholesale market to workcompetitively," said William A. Gaines, Puget Sound Energy vice president of energy supply. "But inthis case, the only thing worse than a price cap is a price cap on only part of the market."

Gaines' remarks came in anticipation of power price limits that could be imposed by the Federal Energy Regulatory Commission in the wake of the agency's investigation into California's wholesale electricity market.

"While Puget Sound Energy strongly supports a competitive marketplace, any federal action thatwill alter the wholesale electric market in one region, needs to apply to all affected parts of thatregion," Gaines added.

In a complaint filed with FERC, Puget Energy pointed out that thousands of power transaction occur each month between California and the Northwest, and told the federal regulators that it is "unfair and unduly discriminatory to protect wholesale purchasers in California with a price cap and yet deny similar protection to wholesale purchasers in another part of essentially the same market, i.e. the Pacific Northwest."
