TerraFlow and DG Matrix deploy VRFB-SST combo to power US AI compute
TerraFlow Energy and DG Matrix announced a commercial agreement on September 28, 2026, to deploy the first integrated vanadium redox flow battery (VRFB) and solid-state transformer (SST) system in the US. The setup will power a live high-performance computing cluster using TerraFlow’s LDUPS and DG Matrix’s Interport technology alongside Dell PowerEdge servers. The goal is to manage rapid power…
Key points
- TerraFlow’s LDUPS combines uninterruptible power with hours-long energy storage to handle compute demand swings
- DG Matrix’s Interport solid-state transformer dynamically routes power between sources and compute loads
- Initial deployment uses Dell PowerEdge servers in a US data center; companies target AI workloads
The companies claim their architecture buffers demand spikes in real time, smoothing out volatility before it reaches the grid. Jon Parrella of TerraFlow called it a shift from treating data centers as grid liabilities to making them assets. DG Matrix’s Haroon Inam emphasized the need for dynamic power control, not just conversion. The deal includes plans to scale the system for future AI infrastructure projects requiring precise power management.
