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.

Geothermal Project Nears Full Operations

LCG, March 13, 2009--Raser Technologies Inc. plans to start delivering 7 MW of electricity next week from its new geothermal facility in Utah to the City of Anaheim, California. The plant output is expected to increase shortly up to 10 or 11 MW.

The power plant facility constructed in southwestern Utah. The system is designed for relatively small temperature differentials, which increases the potential locations that can be developed across the country.

Water is heated by geothermal energy underground, and the energy is transferred to a refrigerant, with the water reinjected underground. The facility uses an organic Rankine cycle-based power system with refrigerant, rather than steam, to generate power in a closed system that has essentially no emissions.

The facility uses 50 modular units provided by UTC Power, a division of United Technologies Corp. The facility was constructed in just over a year.
