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.

AES Proposes 510 Megawatt Long Island Plant

LCG, Nov. 30, 2002--AES Corp. said yesterday that it is in negotiations with the Long Island Power Authority to build a 510 megawatt power plant to help ease possible electricity shortages facing more than a million customers in Nassau and Suffolk counties in New York.

"We've had some discussions with LIPA to build a power plant on Long Island. Those discussions are now becoming more serious," said Dan Rothaupt, an AES official.

The proposed plant would be built at either of two Suffolk County sites -- one in Smithtown or the other in Yaphank. "Sometimes there's a problem building a plant at one site. We're proposing two sites so we have a backup," said Rothaupt, who stressed "We're only looking to build one plant."

Last month, LIPA Chairman Richard Kessel said "Long Island cannot afford to go through another summer without adding a significant amount of new on-island generating capability."

In the past two years, more than 9,000 megawatts of new generation has been proposed for long island, but so far, only 44 megawatts of new capacity has been put into service.

In a filing with the New York Independent System Operator, AES proposed an in-service date of 2005 for the new plant.
