FOR IMMEDIATE RELEASE
Colusa, CA and The Woodlands, TX – March 25, 2026
Strata Expanse’s first partnership with a Tribal Nation, featuring a Center of Excellence (CoE) with plans for expanded energy generation and future development, announced at the 2026 Reservation Economic Summit.
Colusa Indian Energy and Strata Expanse today announced a strategic partnership to develop energy and digital infrastructure on the land of the Cachil Dehe Band of Wintun Indians of the Colusa Indian Community in northern California—an instrumental step to diversify the Colusa Indian Community’s economic base. The collaboration marks Strata Expanse’s first partnership with a Tribal Nation and includes the deployment of an Amphix™ Center of Excellence (CoE), a production-grade environment designed to validate next-generation AI workloads and a core part of the company’s Amphix™ AI Infrastructure Platform.
The project is strengthened by a growing ecosystem of certified technology partners, including DDN, Supermicro, NVIDIA, Intel, and AMD.
The companies are deploying proof of concepts with their technology partners through immediate interconnection to the Colusa Indian Community’s existing microgrid, with plans to expand onsite energy generation capacity to more than 100 MW over the next 18 months to support the CoE. The CoE will serve as a leading-edge incubator for advanced computational models for years to come.
Colusa Indian Energy has established itself as a leader in next-generation energy infrastructure through the Colusa Indian Community’s flagship microgrid, which has operated off-grid in island mode for more than 23 years, including 14 years without a single power outage—demonstrating a level of reliability rarely seen in energy systems. These decades of experience, combined with a team that has delivered more than 2.5 gigawatts of installed capacity across more than 100 countries, position Colusa Indian Energy to bring global expertise and proven performance to advancing innovative energy solutions.
This pre-release coincides with the Reservation Economic Summit (RES) 2026 at Caesars Palace in Las Vegas, where Tribal Nations from across the country gather to discuss economic development opportunities and innovation. Announcing this partnership at RES underscores Colusa Indian Energy’s leadership in emerging technology and energy development, while providing a replicable model for digital and energy infrastructure partnerships that Tribal Nations across the country can adopt.
