The team envisions data centers evolving into frequency-control nodes on the grid—unlocking generation capacity and accelerating renewable integration. Endeavour funds the development of a patented, high-efficiency Brayton-cycle power system built around mass-produced automotive turbochargers. This fast-response generator handles aggressive load transients and block loading, while outperforming CARB emissions standards without aftertreatment.

They conclude that to optimize the performance and reliability of on-site generation assets for irregular frequency control a fundamentally new architecture is needed—close coupling generation to a battery in a unified hybrid system.

The partnership fuses Endeavour’s pioneering vision and systems engineering with BorgWarner’s decades of mastery in turbocharger development, scaled manufacturing, and global supply chains, creating a foundation to bring next-generation power systems to market at multi-gigawatt scale.

The hybrid DC architecture they pioneered for irregular frequency control can be further optimized to address this AI power challenge. By upgrading the battery system to absorb millisecond- and sub-millisecond-level transients and closely coupling the TurboCell system to the server racks, they create a solution that eliminates transients and harmonics at the source.

The hybrid DC architecture delivers unmatched power quality and performance, even under the most demanding loads. The system is verified to provide 99.999% availability, thanks to its design, minimal moving parts, and small failure zone.
