The groundbreaking ceremony was attended by Italy’s Minister of Enterprises and Made in Italy, Adolfo Urso, at the site which used to be used for now-decommissioned industrial activities including polymer storage.

It follows an initial engineering phase and economic, financial and permitting assessments, kicked off in September 2025.

The project pairs an LFP cell manufacturing and BESS assembly plant. The latter will also assemble BESS using modules provided by its Brindisi project joint venture (JV) partner Seri Industrial, from a manufacturing facility in Teverola.

A second phase will see the Brindisi site also host LFP cathode active material production and battery recycling facilities.

In total, the project envisages a capacity of 16GWh per year by 2030, half at Brindisi and half at the Teverola plant, though Eni didn’t specify how much of this was LFP batteries, modules or BESS.
