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.

CA Utility's Deregulation Suit Tentatively Dismissed

LCG, January 9, 2003-Pacific Gas & Electric Company's suit against California regarding price regulation has been tentatively dismissed.

PG&E, the utility and unit of PG&E Corporation, claims that electricity from its nuclear and hydroelectric generating facilities was unfairly subject to regulation by the California Public Utilities Commission in the beginning of 2001.

According to PG&E, California allowed the company's generators to sell electricity at market prices by the passing of AB 1890. During the energy crisis, the state passed AB 6X, which kept the nuclear and hydro power under state price regulation.

PG&E claims that AB 6X is the equivalent of breach of contract, as the company believes AB 1890 functions as a contract. The company asserts it lost $4.1 billion as a result of state controlled prices.

Superior Court Judge Joe Gray found that the initial law did not constitute a contract, although his ruling is only tentative.

The case comes at a time when California is trying to find the source of the spiking electricity prices of 2000 and 2001. Energy suppliers have insisted that limited generating capacity and the high price of natural gas, which fuels many generators in California, forced up the price of electricity that they produced. Therefore, market price for electricity in general was very high. As PG&E's production costs for hydro and nuclear generation were not dependent on the price of natural gas, it could have earned higher returns from the market.

PG&E is slated to emerge from its bankruptcy some time this year, although its legal route to recovery is still being argued in court.
