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.

Connecticut Wrestles with Finding the Right Transmission Solutions
LCG, June 17, 2004--ISO New England stated today that the current design of Northeast Utilities' and United Illuminating's proposed transmission upgrade in Southwest Connecticut would result in a transmission system that continues to have significant reliability issues. ISO New England expressed the need to evaluate alternative transmission designs to ensure a viable solution for the state's and the region's energy needs.The proposed, two-phase upgrade to the Connecticut transmission system includes 345 kV lines in a loop around Southwest Connecticut. Phase I was approved by the Connecticut Siting Council last year, with 12 miles of underground cable. The current hearings address Phase II, which adds 24 miles of underground cable to the transmission loop.
ISO New England Chief Operating Officer Stephen G. Whitley stated in his testimony to the Siting Council that the proposed extensive use of underground cable will not realize the intended reliability benefits, will add costs to Connecticuts customers, and will further delay developing a suitable solution for the state and the region. Whitley requested the Siting Council to enable further study and evaluation of the proposed design and is confident that ISO New Englands concerns do not preclude a solution that could include some portion of underground transmission lines. Whitley said these projects are needed to ensure a reliable supply of power not only for Connecticut but also for all of New England.With respect to reliable supply of power to the region, the Federal Energy Regulatory Commission (FERC) has called today for settlement talks between Connecticut and New York to resolve the dispute regarding the Cross-Sound Cable, which is capable of delivering 330 MW between New Haven, Connecticut and Long Island, New York. The cable was commissioned in 2002 but has seen limited use, as Connecticut says the line violates environmental rules with respect to the depth the Cable, which crosses the Long Island Sound, is buried. New York wants the Cable in use to better ensure reliability and have access to additional supplies. The Cable was brought into service for a period following the August 14, 2003 blackout to assist in bringing the grid back online and improve reliability. "I want the parties to let us know if there is a settlement possible here," FERC Chairman Pat Wood said. The agency will rule on the case on June 24 if no agreement is reached.
