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.

Arrowhead-Weston Transmission Project Moves Forward

LCG, August 27, 2004--The Marathon County Board approved a proposal from American Transmission Company (ATC) to allow a new, 345-kV transmission line through a county-owned recreational area. The overall Arrowhead-Weston line between Hermantown and Wausau will extend 220 miles and is estimated to cost $420 million. The plan calls for completion of the project by 2008. Similar land use agreements will be required with other counties, plus about 850 landowners in Wisconsin and Minnesota.

The Wisconsin Public Service Commission last year approved construction of the Arrowhead-Weston line. Utilities, including Wisconsin Public Service Corp. and Minnesota Power, say it is needed to improve electric reliability. Furthermore, with locational marginal pricing (LMP) to be introduced next year by the Midwest ISO, the additional transmission capacity will tend to reduce locational price volatility.

Earlier this year, Minnesota Power started work on the Hermantown to St. Louis River section and plans to complete the 12-mile segment by early 2005.
