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.

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.

New Power Plan for Ontario Relies on Nuclear and Phases Out Coal
LCG, August 30, 2007--The Ontario Power Authority (OPA) yesterday filed its proposed electricity plan with the Ontario Energy Board (OEB), the energy regulator for the Province of Ontario. Key elements of the plan include: conservation, new renewable generation, natural gas distributed generation, nuclear generation and grid improvements to transmit electricity to the market. Existing coal-fired generation would be phased out by the end of 2014.
The estimated capital cost of the Integrated Power System Plan (IPSP) is C$60 (2007 dollars), with a cost breakdown as follows: conservation, C$10.2; renewables, C$15.4; nuclear, C$26.5; natural gas, C$3.6; and transmission, C$4.0. Approximately three quarters of the transmission cost is associated with renewable resource development.
The proposed plan would roughly double the amount of renewable energy on the grid by 2025. Of perhaps greater interest is the proposal to develop nuclear power to support the growing baseload requirement. OPA plans to add approximately 10,250 MW of nuclear resources, in part through refurbishing existing reactors. Refurbishment could shorten schedules, reduce costs, and better utilize existing infrastructure.
A significant portion of the new supply resources are planned to enable the retirement of over 6,400 MW of coal-fired, generating facilities. The retirements are driven by government commitments to reduce emissions, including greenhouse gases. The environmental benefits estimated by OPA include: sulfur dioxide emissions would decrease by 95 percent, nitrogen oxide emissions would decline by over 50 percent, mercury emissions would be eliminated, and carbon dioxide emissions would decline by over 60 percent.
