Energy provider Flexbase has commenced construction on what will become the world’s largest battery energy storage system (BESS) in Laufenburg, Switzerland.
The Laufenburg Technology Center in the northern canton of Aargau will house a redox flow BESS facility with an eventual battery capacity of 1.6GW and a storage capacity of 2.1GWh.

The site will also host a 480MW AI data center. Construction will be overseen by the Swiss firm Erne and is scheduled to be completed by 2029, with total costs estimated to be between 1 billion to 5.5 billion CHF ($1.27bn-$7bn). DCD has approached Flexbase for comment.
The Laufenburg Technology Center will be situated near the ‘Star of Laufenburg,’ a substation that serves as an interconnection hub for the Swiss and wider European electricity grids.
