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.

WPS Files Application with the Public Service Commission of Wisconsin to Build Combined Cycle Facility at Fox Energy Center

LCG, January 22, 2015--Wisconsin Public Service Corp. (WPS) submitted its application for permission from the state Public Service Commission to install a 400-MW natural gas-fired, combined-cycle generating unit at the Fox Energy Center in Kaukauna, Wisconsin. The estimated cost of the project is $517 million. Construction is anticipated to begin late in the spring of 2016.

The existing Fox Energy Center hosts a 593-MW combined cycle generating facility that began commercial operation in December 2005. WPS originally purchased the power generated from the facility. In March 2013, WPS acquired the dual fuel (natural gas and oil) facility for a total purchase price of $440 million from Fox Energy Center LLC, owned by subsidiaries of Tyr Energy, Inc. and General Electric.

Late in 2013, WPS announced a need for an additional 400-500 MW of electric generating capacity by 2019. Alternatives considered were to purchase power from other energy suppliers, buy an existing or new generating facility, or add another natural gas-fueled generator at the Fox Energy Center.

WPS also operates coal-fired power plants in Wausau and Green Bay, and these coal-fired plants may be taken out of service to avoid the need to invest in equipment and controls to meet increasingly stringent environmental regulations.

A WPS spokesperson stated, "The studies say this is the best thing to do to meet our needs in 2019. It's the right site, it's the right time, it makes great sense.We are able to take advantage of existing cooling water and intake structures, as well as the electric transmission facilities and natural gas pipeline already in place at the site."

The Public Service Commission hearings are planned during the spring and summer, with a ruling likely by year-end.
