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.

PSEG's Bridgeport Harbor H-Class Combined Cycle Project Clears Hurdle

LCG, July 28, 2016--PSEG's proposed combined cycle facility at the existing Bridgeport Harbor Station was reviewed by the Connecticut Siting Council, and the Council issued a declaratory ruling on July 21 that no Certificate of Environmental Compatibility and Public Need is required for PSEG Power Connecticut LLC to build the 485-MW Bridgeport Harbor Unit 5.

The proposed Bridgeport Harbor Unit 5 project will be a natural gas-fired electric generating facility that will replace an existing 384-MW coal unit at the site, which will in turn be retired by July 2021. The new combined cycle facility design includes one General Electric 7HA.02 gas turbine and a steam turbine (a 1x1 design), with total net output of 517.9 MW (winter) on gas. The new plant is expected to primarily run on natural gas, although it will be able to run on ultra-low sulfur distillate (ULSD) as a back-up fuel to provide fuel diversity and better ensure dependability.

Construction is expected to begin next year, with a target completion by June 2019.

The proposed project, along with two other gas-fired projects, cleared the ISO New England (ISO-NE) Capacity auction in February 2016.
