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.

Progress Energy Florida Pursues Renewable Energy

LCG, July 24, 2007--Progress Energy Florida, a subsidiary of Progress Energy, announced late last week that it is issuing a request for renewables (RFR) to expand the company's renewable portfolio, to offset the need for new power plants, and to reduce Florida's dependence on fossil fuels. The pursuit of renewables is consistent with Florida Governor Charlie Crist's recent executive order suggesting a 20 percent renewable portfolio standard for utilities and the Governor's interest in responding to climate change concerns related to the use of fossil fuels.

Progress Energy Florida is targeting cost-competitive, renewable energy projects that are located in Florida and use renewable fuels, including: hydrogen, biomass, solar, geothermal, wind, ocean energy, hydroelectric power, or waste heat from a manufacturing process. The projects must be fully operational by January 1, 2013. The Florida Public Service Commission has pre-approved an as-available contract and a standard offer contract for renewable energy.

Progress Energy Carolinas, another utility subsidiary of Progress Energy, announced in late May its goal to meet customer growth in an environmentally sound manner, including with respect to global climate change issues. Progress Energy Carolinas plans to displace 2,000 MW of electric generation through demand-side management and energy-efficiency programs.

Both Progress Energy Florida and Progress Energy Carolinas are also pursuing the development of new nuclear reactors, which would tend to reduce the carbon intensity (carbon emitted per megawatt hour generated) of the Progress Energy electric generation portfolio. Progress Energy Florida selected a site in Levy County, Florida near its existing Crystal River Energy Complex for the possible construction of a new nuclear power plant. Progress Energy Carolinas plans to build new reactors at Progress Energy's Harris Nuclear Plant in the Carolinas. Progress Energy has not yet made decisions on whether or not to proceed with the installation of any new reactors.
