Eni Brings Battery Production to Italy: The Largest European Site in Brindisi Becomes a Reality
Eni has started work on the new industrial hub in Brindisi dedicated to the production of lithium iron phosphate (LFP) batteries, which will bring stationary battery production directly to Italy. The project, developed by Eni Storage Systems, a company partially owned by Eni Industrial Evolution and FIB of the Seri Industrial group, aims to create an integrated production supply chain specifically destined for Battery Energy Storage Systems (BESS), systems that allow energy produced from renewable sources to be stored and made available when the grid needs it.
The groundbreaking ceremony took place at the Versalis industrial site in Brindisi, in an area that previously hosted activities dedicated to polymer storage and other now-abandoned productions. The repurposing of the site represents the first step towards the realization of what Eni defines as "the first integrated Italian and European hub dedicated to stationary batteries."
The project includes the construction of a gigafactory for the production of LFP cells and modules, alongside a facility for assembling BESS battery packs. The structure will have sufficient capacity to also integrate the modules from the Seri Industrial gigafactory in Teverola, in the province of Caserta.
"An investment that will give rise to an innovative local supply chain capable of generating employment and strategic autonomy from non-EU markets, while reducing emissions without losing competitiveness. Our model of industrial transformation, which combines greater environmental sustainability, economic competitiveness, and energy security, is concrete. It is complemented by Eni's concurrent entry into FAENIX, the company of the Seri Industrial group that will market the storage systems produced in Teverola and Brindisi," said Giuseppe Ricci, Chief Operating Officer of Industrial Transformation at Eni.
LFP batteries represent one of the most widespread technologies for stationary storage due to their operational stability, long lifespan, and competitive costs compared to other lithium-ion chemistries. BESS systems play a fundamental role in managing modern electrical grids because they store energy produced during peak generation from photovoltaic and wind plants and release it when demand increases or production decreases.
According to company estimates, European demand for storage systems will increase from 36 GWh in 2025 to approximately 138 GWh by 2030, a rise that makes this sector increasingly relevant for the development of renewable energies and the stability of the electrical grid.
The industrial plan foresees a total production capacity of 16 GWh per year by 2030, divided equally between Brindisi and Teverola. Once fully operational, the new hub could cover over 10% of the European market for stationary storage systems.
"Phases of deep transformation require courage, vision, and the ability to recognize when certain industrial models are no longer sustainable. And if the answer is an investment in an innovative, competitive activity that is central to the global energy transition, we are proud to be part of it. When change is driven by a solid industrial vision, social responsibility, and the awareness that we need to work together in our country, we are confident that this initiative will be an extraordinary development opportunity for Brindisi and Italy," said Vittorio Civitillo, CEO of Seri Industrial and CEO of FAENIX.
The second phase of the initiative will also include the production of LFP cathode active material and the establishment of a dedicated battery recycling facility, both sized to support the two gigafactories. The goal is to build an autonomous industrial supply chain from non-European suppliers, strengthening national production along the entire value chain.
For Eni, this initiative represents entry into a new industrial sector linked to the energy transition. The company aims to integrate battery production with the development of renewable energies, strengthening energy security, and growing an Italian manufacturing supply chain dedicated to energy storage technologies.
