- Prometheus and Engie agree to colocate data centres with nearby renewable and storage assets in the Dallas area, targeting first go-lives in 2026.
- The plan adds on-site bridging power via Conduit, aiming to ease interconnection bottlenecks while ERCOT tightens rules for very large loads.
What happened: Colocating compute with renewables in Dallas
Prometheus Hyperscale, an AI data-centre developer, signs an exclusive deal with Engie North America to place liquid-cooled sites beside Engie’s wind, solar and battery assets in the Dallas area. The first locations aim to start service in 2026, with more planned from 2027. The idea is direct: put compute next to the power source along the I-35 corridor and use Engie’s local portfolio and trading desk to support it. David Carroll, Engie North America’s chief renewables officer, says the partnership draws on Engie’s assets to deliver “scalable, resilient and sustainable infrastructure.” Prometheus chair Bernard Looney says Engie is a good fit for building next-generation AI capacity. Prometheus also teams with Conduit Power to add near-term on-site bridging and back-up generation, with designs that can reach hundreds of megawatts per site.

Why it’s important
Texas is seeing record electricity demand as data centres multiply and heat pushes peaks higher, and ERCOT now has stronger powers to rein in very large users during grid emergencies. Placing compute next to wind, solar and battery sites can cut interconnection waits, reduce curtailment risk and use storage to steady supply, and on-site dispatchable units can bridge gaps when the grid is tight. This looks like a practical choice in congested ERCOT nodes with sharp price swings. Engie already serves major hyperscalers through big clean-power contracts, so it brings experience in shaping supply for large footprints. The plan still carries risk: any gas-fired bridging will face emissions scrutiny, and curtailment rules can still bite during emergencies. On balance, siting AI-class facilities beside generation and storage improves deliverability and gives operators more options in North Texas’s crowded queue.
