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.

Duke , GPU in South Australian Gas Pipeline

LCG, June 27, 2001Subsidiaries of Duke Energy Corp. and GPU Inc. said yesterday they had formed an alliance to build a natural gas pipeline in Australia, running more than 400 miles from southwestern Victoria to Adelaide in the state of South Australia.

South Australia faces a shortage of natural gas as its current supply comes mostly from the Cooper Basin, which is in decline. Phil Grigsby, commercial development manager for Duke Energy International, said gas from the Gippsland Basin or gas fields proposed to be developed in western Victoria, including new Otway Basin discoveries over the past month could be shipped to Adelaide over the new pipeline.

Both Duke and GPU Gas Net had separately explored the possibility of building a Victoria to South Australia pipeline before the two companies formed their alliance.

Pending the results of a binding open season, the new pipeline could be built in a little more than two years and begin delivering natural gas by the end of 2003, Grigsby said. "I think this is a significant step. The combined efforts of a Duke International and a GPU put a lot of momentum behind a project," he said.

Duke said TXU Australia, which owns the Torrens Island Power Station in South Australia, would be an anchor customer of the new pipeline. Others could be Australian National Power, a subsidiary of the UK's International Power Plc, and the South Australian Magnesium Project.
