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.

Back to the Drawing Board for Salem Harbor Plant

LCG, July 13, 2004--The Federal Energy Regulatory Commission (FERC) issued an order last week for PG&E National Energy Group Inc. - the bankrupt owner of the Salem Harbor Power Plant - to work with ISO New England and others to develop a better plan to address the $85 million environmental cleanup of the plant. The FERC did not approve the plans that would have Eastern Massachusetts electric customers pay environmental cleanup costs.

If an agreement on a new plan that addresses the FERC's concerns is not delivered within 60 days, the FERC will order a full investigation to determine if the plan "may be unjust, unreasonable...or otherwise unlawful."

The Salem Harbor power station includes three coal-fired generating units totaling 313 MW, plus 450 MW oil-burning unit. PG&E has requested ISO New England officials to shut down the plant, given its lack of funds to pay for the environmental cleanup costs. However, from a system reliability perspective, ISO New England sees the plant as needed to avoid blackouts. "The ISO is pleased that the FERC recognizes that a reliability operating agreement for Salem Harbor will be needed until power system conditions improve in the Greater Boston area," said Ellen Foley, a spokeswoman for ISO New England.

Those interested in purchasing the plant from PG&E must address the uncertainties regarding who carries the $85 million cost for environmental clean-up, plus the potential impact of transmission upgrades that would effectively (a) increase the competition between Salem and other generating stations and (b) reduce its "reliability" value from ISO New England's perspective.
