Oklo Inc. (NYSE: OKLO) (“Oklo”), an advanced nuclear power and nuclear fuel recycling company, has signed a memorandum of understanding with RPower, a leading provider of onsite prime an

d backup power solutions, to deploy a phased power model for data centers. This model combines immediate energy deployment using RPower natural gas generators with a transition path to clean, reliable energy from Oklo’s Aurora powerhouses, eliminating reliance on diesel generators and supporting scalable, sustainable operations.

“This collaboration aims to ensure that data centers can access reliable energy today while building a clear and practical pathway to clean energy in the future,” said Jacob DeWitte, Co-Founder and CEO of Oklo. “With a growing customer pipeline and a current order book of 14 gigawatts of energy, we are thrilled to work with RPower to address both immediate and long-term energy challenges.”

Once implemented, the phased power model is expected to work in three stages. Initially, RPower’s natural gas generators will be deployed within approximately 24 months, depending on site conditions, to meet immediate power needs for data centers that the local utility cannot serve. Next, Oklo’s advanced nuclear power solutions, the Aurora powerhouses, will be added to these sites as they become commercially available, providing emissions-free energy. Finally, over time, the Aurora powerhouses will supply the majority of the energy needed, transitioning the RPower natural gas generators to backup and resilience roles and allowing RPower to serve as a Good Grid Citizen^TM by providing extra power to the local grid in times of need.

By leveraging Oklo’s advanced nuclear expertise and RPower’s deep experience with prime and backup power systems, this relationship aims to offer a comprehensive, turnkey solution and speed to market for data centers and other large energy users. Oklo and RPower intend to work together to deploy this phased power strategy on behalf of their respective existing customers as well as new customers who can benefit from this unique combination of immediately deployable natural gas generation with the ability to transition to nuclear energy solutions in the future.

“Our relationship with Oklo represents a powerful way to bridge today’s energy demands with tomorrow’s clean energy solutions,” said Jamie Smith, COO of RPower. “We are excited to bring this phased model to market, providing valuable and timely energy solutions to our customers while advancing their sustainability goals.”
