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.

Mitsubishi Subsidiary Seeks to Build Nevada Plant

LCG, Mar. 4, 2002--Diamond Generating, a subsidiary of Mitsubishi, the Japanese conglomerate, hopes to build a gas-fired generating plant near Goodsprings, Nevada, starting in early 2003.

While many US-based power developers have scaled back the number of projects they are actively pursuing due to a drop in power prices and lender concerns over some power producers' high levels of debt, Bill Davis, director of development of Diamond Generating, said, "there is still an increase in electric load requirements (in the western United States)." The plant would be named Ivanpah Energy Center, and would have a capacity of 500 megawatts.

The plant, which would be dry-cooled, would utilize 30 to 50 acre feet of water for cooling annually, from partially treated gray water generated by the Southern Desert Correctional Center in Jean. A typical dry-cooled plant requires 250 to 300 acre feet. The land on which Ivanpah would be built would be leased from the Bureau of Land Management.

A series of public meetings are scheduled concerning the plant. If the plant receives all required approvals, Diamond hopes to start operations by March 2005.
