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.

Summer 2021 Resource Adequacy Scenarios- Revised Report
LCG June 11, 2021--LCG Consulting (LCG) has released its analysis of resource adequacy in ERCOT for summer 2021, as we do each spring.
Under expected conditions, in agreement with ERCOT’s expectations, our model shows the ERCOT region will have enough installed generating capacity to serve peak loading condition. ERCOT projects peak load as 77,144 MW with a total resource capacity of 86,862 MW.
However, more challenging conditions are always possible. This summer follows what may have been the most extreme weather event to ever test the modern Texas grid, February’s storm that is described as a 1-in-a-100 event. The state is still reeling from its effects, and electricity market participants are facing much stronger public scrutiny of reliability, as well as new legislation, some still pending resolution.
Resource adequacy analysis for the region is critical during extreme summer loading conditions. Reserves have tightened because of recent retirements. The ERCOT landscape is rapidly evolving, with significant transmission changes and unprecedented growth of renewables, particularly wind.
Beside using the conditions that ERCOT itself expects to model this upcoming summer, LCG chose three other scenarios to model: reduced wind output, increased generator outages, and higher-than-expected load.
Each scenario sheds light on where issues might arise and what magnitude of effects might occur.
