CyrusOne and Eolian have partnered to accelerate the development of a 200-megawatt data center campus in Fort Worth, Texas, by co-locating new digital infrastructure with existing high-voltage transmission and substation assets. The project, known as DFW7, sits adjacent to Eolian’s Chisholm Grid site, a 100 MW battery energy storage system that has operated in the ERCOT market since 2021.
The collaboration enables CyrusOne to compress development timelines by reusing grid infrastructure that would be difficult and time-consuming to replicate. Eolian identified the Fort Worth site in 2023 as a location with available substation capacity suitable for large load growth. CyrusOne broke ground on the campus in April 2025, with initial capacity scheduled to come online beginning in 2026.
Beyond speed to market, the project establishes a model for pairing hyperscale data center development with existing grid-scale energy assets. Eolian will modernize and upgrade one of Texas’ earliest utility-scale BESS installations as part of the transaction, while the shared infrastructure supports early phases of data center power delivery. The companies position the Fort Worth campus as a template for supporting AI-driven compute growth while maintaining grid efficiency and reliability.
- 200 MW data center campus under development in Fort Worth, Texas
- Co-located with a 100 MW battery energy storage system operating since 2021
- Uses existing high-voltage transmission and substation infrastructure
- Construction began in April 2025; initial capacity expected online in 2026
- Designed to support hyperscale, enterprise, and AI-driven workloads
“Our customers’ continued growth drives demand for new capacity. Leveraging the existing infrastructure at the Fort Worth campus enables CyrusOne to deliver large-scale capacity to customers beginning in 2026,” said Eric Schwartz, Chief Executive Officer of CyrusOne.
🌐 Analysis
The DFW7 project reflects a broader shift in U.S. data center development toward power-first site selection, as hyperscalers and operators prioritize speed to power over traditional greenfield expansion. By aligning with energy storage developers like Eolian, data center operators can reduce exposure to transmission bottlenecks while advancing AI-ready capacity in constrained markets such as North Texas.
