Oklo and Siemens Energy's Clean Energy Partnership

As the energy sector accelerates toward decarbonisation, one principle remains consistent: procurement determines how quickly innovation can scale.

Advanced energy developers are transforming how they source critical systems — viewing suppliers not as transactional vendors but as partners in engineering long-term resilience. Recent achievements show that early collaboration and strategic contracting can transform next-generation power technologies into practical, deployable solutions.

Oklo and Siemens Energy's partnership

Oklo and Siemens Energy have signed a binding agreement for the design and delivery of the power conversion system for Oklo’s Aurora powerhouse.

The deal authorises Siemens Energy to begin engineering and design activities to accelerate procurement of long-lead components and launch the manufacturing process for the power conversion system.

This partnership combines Oklo’s expertise in advanced fission with Siemens Energy’s renowned steam turbine and generator technologies to deliver clean, reliable electricity through proven industrial equipment.

“We are thrilled to be working with Siemens Energy, a global industry leader and key strategic partner, to bring the Aurora powerhouse online,” says Alexandra Renner, Oklo’s Chief Product Officer.

“Aurora’s inherent safety allows us to use proven, commercially available power systems like Siemens Energy’s turbine technology. That design philosophy shortens timelines, reduces costs, and turns advanced nuclear into a deployable product. We believe this is a historic step forward for the advanced nuclear industry – a real-world purchase that demonstrates progress toward deployment and operation.”

Pioneering advanced fission with proven supply chains

Oklo is developing fast fission plants designed to deliver clean, affordable and reliable energy at scale, while establishing a domestic supply chain for critical radioisotopes and advancing nuclear fuel recycling that converts waste into clean power.

The company was the first to receive a site use permit from the US Department of Energy for a commercial advanced fission plant, was awarded fuel from Idaho National Laboratory, and submitted the first custom combined licence application for an advanced reactor to the US Nuclear Regulatory Commission.

Oklo is also advancing next-generation fuel recycling technologies in collaboration with the US Department of Energy and several National Laboratories.

Under this contract, Siemens Energy will perform detailed engineering and layout for a condensing SST-600 steam turbine, an SGen-100A industrial generator, and related auxiliaries to support Oklo’s first advanced reactor, the Aurora powerhouse, at Idaho National Laboratory (INL).

The power conversion system is one of the major long-lead components required before power operations can begin at the Aurora facility.

All sustainability, net zero and sustainable supply chain leaders should attend:

• Sustainability LIVE: The Net Zero Summit - QEII Centre, London, March 4-5
• Sustainability LIVE: The US Summit - Navy Pier, Chicago, April 21-22

Co-located with Procurement & Supply Chain LIVE, these events brings together CSOs, ESG leaders and senior decision-makers at a moment when sustainability, supply chains and commercial performance are increasingly interconnected.

Tickets can be booked online today for The Net Zero Summit and The US Summit. Group discounts available.

De-risking deployment through strategic equipment agreements

Critical procurement areas for Aurora-INL include fuel, site, and the plant’s power conversion system. Since Oklo has secured both the site and the fuel, the Siemens Energy contract helps de-risk supply chain constraints and production timelines, demonstrating concrete execution capability.

“Siemens Energy and Oklo will develop the best solution for power supply,” adds Tobias Panse, Senior Vice President for Steam Turbines and Generators at Siemens Energy.

“We offer best-in-class solutions for reliable power supply with the highest efficiency. Oklo’s small modular reactor solutions are ideal for companies with large power demand. This agreement brings our partnership to life.”

The partnership benefits both sides: Oklo gains momentum in deploying its powerhouses, while Siemens Energy reinforces its role as a turbine technology provider for emerging clean energy initiatives.

The agreement also establishes the foundation for continued collaboration, creating opportunities to scale advanced powerhouse technologies beyond Aurora-INL and advancing both companies’ shared goals of delivering innovative, reliable, low-carbon power worldwide.
