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.

Impact of Wisconsin Plant Under Construction Must be Re-evaluated

LCG, Feb. 23, 2004--The Public Service Commission of Wisconsin is being required to consider for the second time the possible environmental impact of the Port Washington power plant, a project of Wisconsin Energy on which construction has begun.

The rare situation occurred despite the fact that many environmental groups have not considered Port Washington, with a planned capacity of 1,090 megawatts, a priority. Dane County Circuit Judge Moria Krueger ruled this month in favor of the re-evaluation, based on opposition by Bob Owen, an energy lawyer who does research into suitable locations for wind turbines for clients such as FPL Energy. The gas-fired Port Washington project would replace coal plants.

Owen told the Milwaukee Journal Sentinel that the Public Service Commission has ignored studies for the state from over five years ago that addressed possible effects of global warming. Although he was virtually alone in his dissension, Owen's prior experience in litigation (he opposed a transmission project, and a nuclear plant in the 1970's) contributed to the favorable (at least for him) ruling. According to Wisconsin law, preference must be accorded to less environmentally damaging forms of power generation in the review of new projects.
