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.

KU & LG&E Moving Forward on New Combined Cycle Plant at Cane Run

LCG, August 21, 2012--Louisville Gas & Electric (LG&E) and Kentucky Utilities (KU) recently awarded PCL Industrial Construction (PCL) and Black & Veatch a $583 million contract to design and build a new natural gas-fueled power plant at the Cane Run Station, located in southwestern Louisville.

LG&E and KU announced plans for the combined cycle plant last September. The project is intended to offset in part the retirement of coal units at Cane Run, Green River and Tyrone Stations caused by new federal regulations imposed by the Environmental Protection Agency (EPA). The coal-fired units are scheduled to be retired by 2016.

The companies requested in a Certificate of Public Convenience and Necessity (CPCN) filed last September with the Kentucky Public Service Commission approval to build a 640-MW, natural gas-fired combined cycle generating unit at Cane Run Station.

The new Cane Run facility will incorporate Siemens advanced technology gas turbines and will provide approximately 660 MW of electric generating capacity.

Commercial operation of the Cane Run Station began in 1954. Three of its six coal-fired units are now retired; the remaining Units 4, 5 and 6 provide a combined net generating capacity of 563 MW.
