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.

ERCOT Board Endorses ETT's 345-kV Transmission Project

LCG, September 23, 2011--The Electric Reliability Council of Texas (ERCOT) Board of Directors Tuesday endorsed a 345-kV electric transmission project from the Laredo area into the Lower Rio Grande Valley. The project proposal is from Electric Transmission Texas LLC (ETT), a joint venture between subsidiaries of American Electric Power and MidAmerican Energy Holdings Company.

The Board characterized the $300 million project as "critical to reliability." Last February, Texas experienced rolling blackouts during an extremely cold period, when electric loads were high and a number of generators experienced difficulties in delivering power to the grid.

ETT's President stated, "The endorsement from the ERCOT board clearly establishes the need for this transmission project and paves the way for a Certificate of Convenience and Necessity (CCN) application from the Public Utility Commission of Texas (PUCT). Currently, there are only two 345-kV transmission lines serving the Valley. Both of the existing lines import power from the Corpus Christi area and run parallel to the Gulf Coast, which means both are vulnerable to hurricanes and other severe weather. The import capacity of these lines is limited, and the ability to schedule maintenance often can be a problem."

The 345-kV transmission project will extend approximately 163 miles and connect ETT?s Lobo Substation near Laredo with substations north of Edinburg. In addition, the Board supported the need for AEP Texas to reconductor two existing 345-kv lines and to upgrade substation facilities. These improvements are estimated to increase the project cost by $225 million. Given timely environmental and regulatory approvals, ETT anticipates that the project will be completed for 2016.
