Eni Storage Systems starts LFP battery plant
Analysis based on 6 articles · First reported Mar 09, 2018 · Last updated Jul 10, 2026
The construction of the LFP battery hub positions Eni and Seri Industrial to capture a significant share of the growing European BESS market, potentially boosting their revenues and strategic autonomy. The separate lithium investment in Chile secures upstream supply for battery production, positively impacting Eni's vertical integration.
City Storage Systems, a joint venture between Eni Industrial Evolution and FIB (Seri Industrial Group), has begun construction of a lithium-iron-phosphate (LFP) battery production hub in Brindisi, Italy. The facility includes a gigafactory for battery cells and modules, a BESS assembly plant, and future phases for LFP cathode production and battery recycling. By 2030, the combined capacity of Brindisi and Teverola is expected to reach 16 GWh per year, representing over 10% of the European stationary storage market. The project supports renewable energy deployment and grid stability, with European BESS demand projected to grow from 36 GWh in 2025 to 138 GWh in 2030. Separately, Eni has agreed to acquire a 25% stake in Black Giant, a Chilean subsidiary of Energy Exploration Technologies, for a total phased investment of $225 million, to develop a lithium extraction project in northern Chile.
