TerraFlow Energy and DG Matrix to Integrate Vanadium Flow Batteries with Solid-State Transformer Technology for AI Data Centres



New U.S. deployment will combine long-duration vanadium flow battery storage with programmable power conversion to support rapidly changing AI computing loads

TerraFlow Energy and DG Matrix have announced a commercial agreement to deploy an integrated vanadium flow battery (VFB) and solid-state transformer system to power a live high-performance computing cluster in the United States. The project brings together long-duration energy storage, advanced power electronics and AI computing infrastructure in a single system. 

Announced on 28 September 2026, the initial deployment will combine TerraFlow Energy’s long-duration uninterruptible power system (LDUPS), DG Matrix’s programmable Interport solid-state transformer, and Dell PowerEdge servers. The system is intended to manage power dynamically between the grid, on-site generation, energy storage and computing loads.

Vanadium Flow Batteries Supporting the Growth of AI

The rapid expansion of artificial intelligence and high-performance computing is creating increasingly demanding electricity requirements. Large GPU clusters can experience rapid changes in power demand as computing workloads fluctuate, presenting new challenges for electrical infrastructure and grid management. 

The TerraFlow–DG Matrix system is designed to absorb these rapid variations in computing demand before they propagate upstream into the wider electrical system. TerraFlow’s LDUPS combines uninterruptible-power functionality with hours of energy storage, while DG Matrix’s Interport technology provides programmable power conversion and routing between power sources, storage and computing equipment.

At the centre of the project is vanadium flow battery technology, which is expected to provide both fast response and multi-hour energy capacity. TerraFlow’s LDUPS architecture is designed around modular 1.25 MW building blocks with scalable energy duration.

This combination could enable vanadium flow batteries to perform a broader role than conventional short-duration UPS batteries. Rather than providing only brief ride-through power during interruptions, long-duration storage can potentially support power-quality management, load balancing and longer-duration energy requirements within an integrated data-centre power architecture. 

A New Application for Vanadium Energy Storage

TerraFlow and DG Matrix describe the project as the first integrated U.S. architecture combining a vanadium flow battery with a solid-state transformer to directly power a live high-performance computing cluster. This is a company characterization and has not yet been independently established across the market. 

The deployment will provide an opportunity to assess the technology under real AI workloads, including how rapidly the storage system responds to changes in computing demand, the extent to which it can smooth upstream load variations, the efficiency of power transfer and whether multi-hour storage can be provided while maintaining the fast response required of UPS systems. 

The project also demonstrates an emerging opportunity for vanadium flow batteries in the rapidly expanding data-centre sector, where long-duration energy storage could complement grid supply and on-site generation while helping manage increasingly dynamic computing loads.

Details including the installation location, overall megawatt load, battery energy capacity, project cost and expected commercial-operation date have not yet been disclosed.
