TerraFlow and DG Matrix Deploy Integrated VRFB and SST Architecture for US Data Centers

Pioneering VRFB and SST Integration

TerraFlow Energy and DG Matrix have announced a commercial agreement to deploy the first integrated vanadium redox flow battery and solid-state transformer architecture in the United States. This live deployment is designed to power high-performance computing clusters, marking a significant technological leap for data center energy management.

TerraFlow's LDUPS Platform

The deployment utilizes TerraFlow's Long-Duration Uninterruptible Power System. Unlike traditional backup systems, this platform features modular power blocks ranging from 1.25MW to 25MW, with energy durations spanning four to over 48 hours. It boasts a nominal response time below five milliseconds, actively managing power quality and smoothing rapid compute-driven load ramps.

Upgraded Solid-State Transformer

Complementing the flow battery is DG Matrix’s Interport solid-state transformer technology. In September 2026, DG Matrix upgraded its Interport power module capacity from 200kW to 400kW using silicon carbide devices from STMicroelectronics. This upgrade maintains the same module footprint, significantly improving power density for demanding data-center applications.

TerraFlow's battery-in-building architecture combines uninterrupted power, long-duration energy storage, and controllable load management in a single platform, turning large electrical loads into flexible grid assets.

By integrating Dell PowerEdge servers with this advanced storage and transformer architecture, the partnership aims to address the massive and fluctuating power demands of AI-driven data centers. The synergy between the long-duration flow battery and the high-efficiency solid-state transformer creates a highly resilient microgrid environment. This is particularly crucial for AI workloads that require continuous, high-quality power without the risk of voltage sags or interruptions. This non-flammable, long-duration approach offers a robust alternative to conventional lithium-ion setups, ensuring both operational continuity and grid stability. Ultimately, this deployment sets a new industry standard for sustainable data center operations.
