Endeavour has announced TurboCell, a rapidly deployable, scalable power system designed to accelerate time-to-power for AI cloud providers facing utility expansion and generation-capacity constraints. The company says TurboCell provides immediate, gigawatt-scale prime power for early operations and then transitions to long-term backup after grid connection, aiming to avoid stranded power assets as sites move from temporary bridging to permanent utility service.
Endeavour positions TurboCell for AI data center electrical behavior characterized by large, fast load steps. The company notes that thousands of GPUs can drive abrupt transitions between idle and peak load, producing megawatt-scale power swings that lead to electrical transients, voltage sags and swells, and frequency excursions. According to Endeavour, TurboCell addresses this with a Hybrid DC architecture intended to stabilize volatile AI loads at the source and prevent disturbances from propagating into GPU power-delivery systems, on-site generation equipment, or the utility grid.
“TurboCell is our answer: A rapidly deployable high-speed generator and hybrid battery system that delivers gigawatt-scale power with the real time stabilization needed to absorb large AI power swings,” said Chris Ellis, CEO of TurboCell.
Endeavour says TurboCell uses standardized modular units with minimal moving parts to reduce failure domains, improve fault isolation, and provide redundancy. Data center reliability expert Steve Fairfax is quoted as saying, “When deployed in appropriate configurations, the inherent availability of power from arrays of TurboCell engines exceeds 99.999%.” The company also says TurboCell’s modular architecture, resilient supply chain, and streamlined oneline support on-demand scaling and allow cloud providers to reallocate power after deployment as AI requirements change.
On emissions and permitting, Endeavour claims TurboCell delivers “ultra-low emissions” and can run on natural gas, diesel, and hydrogen. The company reports emissions reductions “without aftertreatment,” citing “94% lower emissions than diesel generators” and “86% lower emissions than natural gas turbines,” with the footnote specifying nitrogen oxides (NOx) comparisons against published manufacturer specifications for Tier 2 diesel or a natural gas turbine using the same fuel source.
Endeavour says TurboCell includes a standard two-year warranty with a five-year option and 24/7 support, supports non-disruptive maintenance, and has a minimum 80,000-hour product life. The company reports it is ramping US manufacturing capacity to multi-gigawatt scale and that TurboCell will begin shipping in 2026, with orders open now for 2027 delivery. Endeavour says TurboCell is available exclusively through Edged Infrastructure.
