Eni Brindisi Battery Plant: LFP Gigafactory Construction Begins

July 8, 2026 — Eni Storage Systems has begun construction of a new battery plant in Brindisi, Italy, a key advancement in Europe’s energy storage manufacturing. The groundbreaking ceremony took place on July 6, 2026, with Italy’s Minister of Enterprises, Adolfo Urso, in attendance.

This Eni LFP battery gigafactory project transforms a former Versalis industrial site into an integrated hub for lithium-iron-phosphate (LFP) batteries. The initiative aims to strengthen Italy’s role in the battery energy storage sector while supporting the wider energy transition across Europe.

The plant will primarily supply Battery Energy Storage Systems (BESS), which are critical for managing the intermittency of renewable energy sources. This development positions Italy as an emerging player in stationary storage manufacturing.

Project Overview

The Eni Brindisi battery plant will focus on producing LFP batteries optimized for stationary Battery Energy Storage Systems (BESS). These systems store excess renewable energy when generation is high and release it during peak demand, stabilizing grids and enhancing renewable integration.

Local production of LFP batteries in Italy meets the rising European demand for sustainable energy storage solutions. It combines advanced manufacturing with circular economy principles through future recycling capabilities.

Key Details of the Brindisi Battery Plant

• Capacity: 8 GWh in Brindisi + 8 GWh at the Teverola plant = 16 GWh total annual production by 2030, representing over 10% of the projected European stationary BESS market.
• Timeline: Groundbreaking on July 6, 2026, with full operations phased in toward the 2030 target.
• Components: Gigafactory for battery cells and modules, expanded BESS assembly plant, LFP cathode active material production, and battery recycling facilities in later phases.
• Joint Venture: Eni Seri Industrial joint venture Eni Storage Systems is jointly owned by Eni Industrial Evolution and FIB (Seri Industrial Group). The Brindisi site will also integrate modules from Seri’s Teverola gigafactory in Caserta.

Market Context and European Demand

European demand for stationary battery energy storage is accelerating rapidly. According to Wood Mackenzie, the market is expected to grow from 36 GWh in 2025 to around 138 GWh by 2030. Ambitious renewable energy targets, the need for grid modernization, and increasing electrification across the continent drive this surge.

The Eni Brindisi battery plant is crucial as Italy and the EU aim to lessen dependence on imported batteries, mainly from Asia. Domestic LFP production strengthens supply chain resilience for Italy’s battery energy storage projects.

Statements from Leaders

“Today, we are launching in Brindisi an industrial initiative that marks Eni’s entry into an entirely new business with significant growth potential. This project is designed to support the energy transition by creating industrial and technological value in a sector that is crucial to the decarbonisation process, combining the development of renewables with the resilience of the energy system. This investment will establish an innovative local value chain capable of generating employment and strengthening strategic autonomy from non-EU markets, while reducing emissions without compromising competitiveness. Our industrial transformation model, which combines greater environmental sustainability, economic competitiveness and energy security, is now a tangible reality. It is further strengthened by Eni’s investment in FAENIX, the Seri Industrial Group company, made in parallel that will market the energy storage systems produced in Teverola and Brindisi”, said Giuseppe Ricci, Eni’s Chief Operating Officer for Industrial Transformation.

“Periods of profound transformation require courage, vision and the ability to recognise when certain industrial models are no longer sustainable. When the answer is investment in an innovative, competitive business that is central to the global energy transition, we are proud to be part of it. When change is driven by a strong industrial vision, social responsibility and the awareness that we must work together as a country, we are confident that this initiative will become an extraordinary opportunity for growth for Brindisi and for Italy”, said Vittorio Civitillo, Chief Executive Officer of Seri Industrial and of FAENIX.

Strategic Importance for Italy and Europe

The Eni LFP battery gigafactory delivers multiple benefits for the energy transition and grid stability. It enhances solar and wind power integration, balancing supply and demand while reducing renewable generation curtailment.

The project is expected to generate employment in Brindisi and surrounding regions, supporting local economic development. It enhances Italy’s strategic autonomy in clean tech supply chains, reducing reliance on non-EU suppliers for LFP batteries.

What Are LFP Batteries and Why Do They Matter?

LFP (lithium-iron-phosphate) batteries are a safe, long-lasting, and cost-effective lithium-ion option compared to nickel-based alternatives. They contain no cobalt or nickel, making them more environmentally friendly and less vulnerable to volatile raw material prices.

In stationary storage applications like BESS, LFP’s durability and thermal stability make it the preferred choice for utility-scale and grid-support projects. This technology aligns perfectly with Europe’s goals for sustainable, long-duration energy storage.

What This Means for the Future

The launch of the Eni Brindisi battery plant signals Italy’s growing ambition in the European battery ecosystem. This creates a domestic value chain from cathode materials to finished BESS systems, combining the Teverola facility and FAENIX’s marketing.

As Europe races toward its 2030 climate targets, projects like this will be essential for grid reliability and energy security. The Eni Seri Industrial joint venture sets a model for how traditional energy companies can pivot successfully into storage manufacturing.
