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.

Florida PSC Approves New Nuclear Station Proposed by Progress

LCG, July 16, 2008--The Florida Public Service Commission (PSC) yesterday approved a proposal by Progress Energy Florida (Progress) for a determination of need to build two, 1,100-MW nuclear reactors at a greenfield site in Levy County, Florida. The first reactor is scheduled to be operational in 2016, and the second reactor in the following year. Progress submitted the petition to the PSC in March.

The new units, together with increased demand-side management (DSM) programs and renewable energy power purchase agreements, are forecast to meet the power supply needs of Progress through 2023 without increasing greenhouse gas emissions.

Progress plans to install two Westinghouse AP1000 reactors. In April, Progress announced that it had executed a letter of intent with Westinghouse Electric and The Shaw Group Inc. to purchase long-lead materials for the new nuclear reactors that are to be installed.

Progress is not the only utility planning to build nuclear reactors in Florida. In March, the PSC approved a petition by Florida Power and Light (FPL) for a determination of need to build two more nuclear reactors at its Turkey Point facility south of Miami. These proposed units are scheduled to commence operations in 2018 and 2020.
