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.

SWEPCO Announces Plans for New Coal-fired Power Plant in Arkansas
LCG, August 10, 2006--Southwestern Electric Power Company announced yesterday that it has selected a site in Hempstead County, Arkansas, for a new, 600-MW, coal-fired electric generating station. The location is approximately 15 miles northeast of Texarkana.
Southwestern Electric Power Company (SWEPCO), an affiliate of American Electric Power (AEP), stated that the planned new station will employ an ultra-super critical design and burn sub-bituminous, Powder River Basin coal from Wyoming. The estimated cost for the new plant is $1.3 billion, and the project is scheduled to commence operations by the summer of 2011.
AEP has plans to build two new coal-fired plants elsewhere in the east that use an Integrated Gasification Combined Cycle (IGCC) design, and these plants would consume coal with different qualities than that planned for the SWEPCO facility. According to SWEPCO, the difference in coal qualities requires IGCC technology other than the GE technology planned for the other two sites, and adequate performance guarantees were not available to support deployment of IGCC technology at the SWEPCO plant.
The announcement falls on the heels of similar announcements regarding new coal-fired generation capacity in the region. Earlier this month, Plum Point Energy Associates, LLC, a member of the LS Power Group, announced that it has signed a power purchase agreement with South Mississippi Electric Power Association to deliver electricity from the Plum Point Project, a greenfield, coal-fired power project with a design capacity of 665 MW. Construction on the Plum Point Project, located near Osceola, Arkansas, began in March of this year, and commercial operations are scheduled to commence in mid-2010. Plum Point is a member of the LS Power Group of St. Louis, Missouri.
Last month AEP, together with a group of electric utilities, announced plans to build a new, 950-MW, coal-fired power plant in north-central Oklahoma. The estimated cost of the new facility is $1.8 billion, and this project - like the SWEPCO project - would burn coal from the Powder River Basin. The project will be a joint venture of AEP's Public Service Company of Oklahoma, Oklahoma Gas & Electric Company (OG&E) and the Oklahoma Municipal Power Authority (OMPA).
