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.

UK's Ofgem Chief: Dereg Doesn't Mean California

LCG, Oct. 11, 2001--Callum McCarthy, head of British energy regulatory body, the Office of Gas and Electricity markets, was in Washington, D.C., yesterday, where he told the European Institute that electric deregulation doesn't necessarily lead to a California-style energy crisis.

"California is not the inevitable result of liberalizing energy markets," McCarthy said. "The British experience, as well as that in the Nordic countries of Europe and individual states in Australia, show that privatization and liberalization can bring very real customer benefits."

McCarthy said the British experience showed quite the opposite -- he said 14 million customers have switched their sources of supply, with 167,000 switching every week. All of those customers, he said, benefit from the downward pressure on prices which competition has brought and continues to exert.

Since the UK privatized and deregulated its energy sector, residential gas prices have fallen 37 percent and residential electricity prices 28 percent, McCarthy said. Today, Britain has a more diverse energy mix than at any time in its history, interruptions are even rarer today than they were a decade ago and generation capacity exceeds demand by almost 30 per cent, he added.

"There is not much, therefore, that is obviously wrong with the way in which the British energy market operates," McCarthy concluded. "Those who search for market failures to correct have some difficulty in identifying what they are. They have even more difficulty in demonstrating that there is an administrative solution which will improve matters."
