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.

California Approves 1,060 Megawatt Duke Project

LCG, Oct. 26, 2000--After 14 months of deliberations the California Energy Commission has approved a plan by Duke Energy Corp. to replace five idle units at an existing power plant with two natural gas-fired combined-cycle units producing 1,060 megawatts of electricity.

You can imagine the amount of thinking that goes into approving a power plant where one did not previously exist.

Duke will tear down five units at the Moss Landing facility it purchased from Pacific Gas & Electricity Co. and replace them with the two new units. The old units, taken out of service five years ago, produced 613 megawatts. Two other units at the plant, which remain in service, have a combined capacity of 1,530 megawatts.

When the $500 million project is complete in the spring of 2002, Moss Landing will have a capacity of about 2,590 megawatts.

Duke had to pay for the approval. The company will contribute $7 million to support steps that mitigate the impacts of the power plant's operations on the area's marine biology. The decision also requires the company to pay $425,000 to the Monterey Bay Sanctuary Foundation to fund the Coastal Waters Evaluation Program.

Since the California electric industry restructuring law was enacted in the late summer of 1996, about 15,000 megawatts of new power projects have been announced for the state, which this past summer experienced 31 days of electric power shortages.

So far, the Energy Commission has approved six of the projects, including Moss Landing, having a total capacity of about 4,700 megawatts. Of that, around 2,000 megawatts is expected to enter commercial operation next summer.
