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.

El Paso Gets Okay to Reopen Killer Gas Line

LCG, July 9, 2001El Paso Energy Corp. has been given permission to resume natural gas transmission on its pipeline which was shut down by an explosion last August killing 12 people camped alongside it near Carlsbad, N.M.

El Paso's South Mainline system consists of three trunklines that carry gas from West Texas to California. Together, they were carrying about 1.1 billion cubic feet of das per day at the time of the rupture. Following the blast, transmission was cut to 835 million cubic feet per day but has recently held steady at around 920 million cubic feet.

The Department of Transportation said on Friday that El Paso could begin operating the damaged line at 80 percent of capacity as it completes its final inspection of repairs. Patricia Klinger, a DOT spokeswoman, explained "The line needs to be running to conduct internal inspections."

"They are finished with the reconstruction, the hydro testing and internal cleaning. Just the internal inspection is required now," Klinger said. Federal inspectors will make the final determination whether the pipeline can run at full capacity, she added.

El Paso has begun switching the flow of gas from one of the others pipeline to the repaired line, but that will not for the time being increase the overall amount of gas heading to California, a company spokeswoman said. She said shippers would be notified when increased pressure allowed additional gas to be moved.

The federal agency fined El Paso $2.52 million last month for the fatal explosion, the largest fine ever against a gas pipeline operator.
