Spain’s largest battery plant is rising in Aragon. CATL, the world’s biggest battery maker, and automaker Stellantis broke ground in late 2025 on a roughly €4.1 billion gigafactory near Zaragoza, sited beside Stellantis’s existing Figueruelas vehicle plant. Production is scheduled to begin by the end of 2026, supplying lithium iron phosphate batteries to electric vehicles across Europe.
Project Scope
The plant targets 50 gigawatt-hours of annual LFP battery output and is designed to run entirely on renewable energy, a point both partners have pushed as central to the facility’s carbon case. The project is expected to create around 4,000 jobs once operational. Co-locating next to Stellantis’s assembly plant shortens the supply chain between cell and car, one of the reasons the joint venture chose the site.
Battery gigafactories carry construction demands that ordinary industrial buildings don’t: dry rooms, tight environmental controls, and heavy process infrastructure that drive the schedule and the cost well beyond the shell.
Why It Matters
The Zaragoza plant is a marker for Europe’s push to localize EV battery production rather than depend on imported cells. Pairing the world’s largest battery manufacturer with a major automaker, and powering the whole operation on renewables, sets a template for how the continent intends to scale electrification. For the surrounding region, a 50 GWh plant and 4,000 jobs anchor a new industrial cluster, and the all-renewable design signals where heavy manufacturing siting is headed as carbon accounting tightens.
