Crusoe and Redwood Materials expand partnership with 20 more Crusoe Spark modular data centers

Crusoe and Redwood Materials expanded their partnership at Redwood Materials’ campus in Sparks, Nevada, adding 20 more Crusoe Spark modular data centers. The update centers on scaling renewable-powered Artificial Intelligence (AI) computing capacity on the same energy system used for an earlier June 2025 deployment.

In June 2025, the companies deployed a Redwood Energy 12 megawatts / 63 megawatt-hour microgrid to support four Crusoe Spark modular data centers. Since commissioning, the system reported 99.2% operational availability over seven months of continuous operation with minimal unplanned downtime.

The project used solar power alongside repurposed Electric Vehicle (EV) batteries. The batteries were integrated through Redwood Energy’s Pack Manager technology to orchestrate power for compute workloads including Crusoe Spark modular AI factories for Crusoe Cloud. The companies said the reported uptime validated this approach for reliable 24/7 power.

For the expansion, the companies moved the campus deployment from four to 24 Crusoe Spark modular data centers, bringing total compute capacity to nearly seven times the original deployment. JB Straubel, Founder and CEO of Redwood Materials, said, “Since launch, the Redwood Energy and Crusoe system has demonstrated that repurposed EV batteries can reliably power high-performance compute workloads at scale.” Cully Cavness, Co-Founder, President and Chief Strategy Officer of Crusoe, said, “By expanding our work with Redwood Energy to 20 megawatts, we are proving that the ‘AI factory’ of the future can be quickly scaled through the convergence of innovative energy solutions and modular infrastructure deployment.”

The companies said the expanded collaboration adds additional compute capacity on the same system after the June 2025 launch.
