SANTA CLARA, Calif.--(BUSINESS WIRE)-- Oklo Inc. (NYSE: OKLO) and Siemens Energy have signed a binding contract for the design and delivery of the power conversion system for Oklo’s Aurora powerhouse. The agreement authorizes Siemens Energy to begin engineering and design work to expedite procurement of long-lead components and initiate the manufacturing process for the power conversion system. This partnership on key components combines Oklo’s expertise in advanced fission technology with Siemens Energy’s industry-leading steam turbine and generator systems to deliver clean, reliable electricity using proven industrial equipment.
Under the contract, Siemens Energy will conduct detailed engineering and layout activities for a condensing SST-600 steam turbine, an SGen-100A industrial generator, and associated auxiliaries to support Oklo’s first advanced reactor, the Aurora powerhouse at Idaho National Laboratory (INL). The power conversion system represents one of the major long-lead procurements required to commence power operations of the Aurora powerhouse. Key procurement areas include fuel, site, and the plant power conversion system and, since Aurora-INL has fuel material and the site allocated, this contract with Siemens Energy for the power conversion system helps to de-risk supply chain and production timeline challenges and demonstrates concrete execution capability.
“Siemens Energy and Oklo will develop the best solution for power supply,” said Tobias Panse, Senior Vice President, Steam Turbines and Generators, 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.”
“We are thrilled to be working with Siemens Energy, a global industry leader and key strategic partner, to bring the Aurora powerhouse online,” said Alex 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, lowers 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.”
The collaboration showcases mutual benefits: Oklo accelerates powerhouse deployment while Siemens Energy expands its leadership in delivering turbine technology for next-generation clean energy projects. This partnership establishes a foundation for long-term collaboration, enabling future scaling of advanced powerhouses beyond the Aurora-INL and reinforcing both companies’ shared commitment to innovation and dependable, low-carbon power for global customers.
