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.

Transco Files Application for Southeastern Trail Expansion Project with FERC

LCG, April 13, 2018--Williams Partners L.P. announced yesterday that Transco has filed an application with the Federal Energy Regulatory Commission (FERC) seeking authorization for its Southeastern Trail Expansion Project. The expansion of the Transco natural gas pipeline system would create 296,375 dekatherms per day of additional firm transportation capacity to serve the growing markets in the Mid-Atlantic and Southeast. The application reflects an expected capital cost of $404.8 million and a target in-service date of November 1, 2020. The proposed schedule includes starting construction in August 2019.

Transco is a wholly owned subsidiary of Williams Partners L.P., of which Williams owns approximately 74 percent, including the general-partner interest. Transco delivers natural gas through its pipeline network whose mainline extends nearly 1,800 miles between South Texas and New York City and serves markets in 12 Southeast and Atlantic Seaboard states, including major metropolitan areas in New York, New Jersey and Pennsylvania.

Williams Partners has executed precedent agreements with utility and local distribution companies (LDCs) located in Virginia, North Carolina, South Carolina and Georgia for 100 percent of the firm transportation capacity. Customers served by the project are PSNC Energy, South Carolina Electric & Gas, Virginia Natural Gas, the City of Lagrange, Georgia, and the City of Buford, Georgia.

"Southeastern Trail is a critical project that will work to bring key supplies from interconnects in the Mid-Atlantic region to growing demand centers in the Southeastern U.S.," said the chief operating officer of Williams Partners' general partner. "This vital project, along with additional expansion opportunities under development, will link low-cost supply to key customers in high-growth markets and continues the expansion of southbound capacity on the Transco pipeline system. Construction of this project along Transco's existing corridor results in significantly less environmental impact and more economical transportation rates for our customers than other greenfield projects serving these same markets."

The proposed Southeastern Trail Expansion project will consist of approximately 7.7 miles of 42-inch pipeline looping facilities in Virginia, horsepower additions at existing compressor stations in Virginia, and piping and valve modifications on other existing facilities in South Carolina, Georgia, and Louisiana to allow for bi-directional flow.
