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.

Rule Issued on Connecting Generators to Transmission Grid

LCG, July 23, 2003--The Federal Energy Regulatory Commission intends to minimize the effort spent on negotiations between transmission providers and generators, with the issuance of a final rule specifying what costs are to be paid by either party when a generator with capacity of at least 20 megawatts is connected to the transmission system.

A generator owner connecting to transmission operated by a company that is not independent will need to pay for costs on the generation side of the transmission infrastructure. Upgrades to the transmission side during the would also be paid by the generator owner, although the payments could be refunded by the transmission provider.

Existing interconnection agreements will be maintained as they are currently. Regional transmission organizations will have some flexibility, and could engage in what is called participant funding for the first year of the rule being issued. A rule covering generators below 20 megawatts will be issued shortly, FERC has said.
