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.

South Field Energy Breaks Ground for 1,182-MW Power Plant

LCG, May 16, 2019--South Field Energy LLC announced yesterday its groundbreaking for an 1,182-MW, combined-cycle electric generating facility in Columbiana County, Ohio. The natural gas-fired facility is scheduled to commence operations in mid-2021 and represents a $1.3 billion investment.

The project is Advanced Power's second such project in northeastern Ohio and third major infrastructure project in the United States. The South Field Energy project is similar to Advanced Power's Carroll County Energy, a 700-MW combined-cycle facility that began commercial operations in December of 2017.

The South Field Energy facility will include two General Electric 7HA gas turbines, each with an associated GE heat recovery steam generator (HRSG) and steam turbine generator. When completed, the facility will employ approximately 25 full-time employees in engineering, technical, operation, management and administrative positions. The new facility is located on less than 20 acres of land that is part of a 150-acre parcel three miles from the Village of Wellsville.

Advanced Power's Chief Operating Officer, Development, stated, "With facilities like this, we can close the growing gap Ohioans face in energy production. We will accomplish this using advanced technology to produce substantial, reliable, low-carbon electricity generation, while minimizing our environmental footprint."

Bechtel is serving as general contractor for the project. Bechtel also served in the building of Advanced Power's Carroll County Energy Facility and Cricket Valley Energy Center in New York.

Advanced Power announced last August that it had successfully closed a $1.3 billion financing for the construction of the project.
