Data centre developer CyrusOne and independent power producer (IPP) Eolian have announced the deployment of a 200MW data centre campus at a pre-existing grid-scale battery energy storage system (BESS) site in Fort Worth, Texas, US.
The data centre DFW7, which is currently under construction, will offer additional digital infrastructure capacity for hyperscaler and enterprise companies.
CyrusOne and Eolian state that by utilising the existing high-voltage transmission infrastructure and substation capacity near DFW7, the companies have sped up the time-to-market for the strategic site.
DFW7 will be located near developer Able Grid’s 100MW Chisholm Grid BESS, which began operating in 2021.

Construction on Chisholm Grid began in 2020, through partners Able Grid, MAP Energy, Astral Electricity, and Mortenson.
In 2021, solar inverter manufacturer Sungrow announced it had signed a contract to supply the fully integrated battery storage system for Chisholm.
Eolian claims it identified this data centre opportunity for CyrusOne in 2023, enabling it to break ground in April 2025 and compress the timeline for data centre deployment.
Eolian presented the Fort Worth industrial campus to CyrusOne, leveraging its operational experience at the BESS facility and recognising the substation as “a key piece of infrastructure” for regional load growth.
Through this deal, Eolian will modernise and upgrade one of Texas’s earliest utility-scale BESS systems, with the existing infrastructure supplying energy for the initial digital infrastructure phases.
Often, BESS projects supply data centres via offtake agreements and are typically constructed in a different location.
A similar co-located project, though in a reversed order of data centre and BESS deployment, was announced in October 2025 by developer Calibrant Energy. That project will see Calibrant delivering a 31MW/62MWh BESS at Aligned Data Centres’ campus in the Pacific Northwest area of the US.
The on-site system, planned to be operational sometime this year, will similarly enable the facility to begin and scale up its operations several years earlier than traditional utility upgrades would allow.
CyrusOne, headquartered in Dallas, Texas, currently operates over 55 data centres across the US, Europe, and Japan.
The Energy Storage Summit USA will be held from 24-25 March 2026, in Dallas, TX. It features keynote speeches and panel discussions on topics like FEOC challenges, power demand forecasting, and managing the BESS supply chain. For complete information, visit the Energy Storage Summit USA website.
