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.

Northwest Power Picture Brightens

LCG, June 6, 2001The energy crunch affecting the Pacific Northwest is loosening, according to a report in this morning's Seattle Times, and none of the improvement can be laid to increased rainfall.

New supply that is, additional sources of electricity beyond the region's highly developed hydroelectric infrastructure has brightened the picture, with better reliability forecast for summer and lower regional rate increases this coming fall, the paper said.

"Things are looking better than they were," Mark Crisson, director of Tacoma Public Utilities, told the Times. "In fact, I think there is going to be a huge overreaction to the situation in terms of new supply. If we had had anything close to a normal water year, we wouldn't even be having this conversation."

Bonneville Power Administration says it has received transmission applications for between 25,000 and 30,000 megawatts of proposed power plants. Ed Mosey, a spokesman for Bonneville, said "There isn't a site in the Northwest with a source of gas and transmission capacity that isn't being looked at." Most of the plants won't be built, but enough will to ease the crunch in future years, if not this.

The Northwest Power Planning Council announced May 25 that power supplies are expected to be reliable throughout the summer, with no risk of blackouts. That does not mean the Northwest is immune into the fall and winter. If the drought continues, a shortage of power, with blackouts, is possible.
