According to Italia Solare's assessment, as of September 30, 2025, Italy had 848,814 connected electrochemical storage systems, representing a total energy capacity of 17,416 MWh and total power of 7,068 MW. Italian electricity transmission system operator Terna has published the results of 2025's main capacity market auction. The conclusion comes from Italia. In the first three months of 2025, five new battery storage plants went into operation, bringing the installed capacity of our battery energy storage systems (BESS) in Italy to 1 GW. This move underscores the country's growing commitment to grid resilience, energy. The Italian energy storage market is expected to experience its second consecutive year of decline in 2025, with new installations falling to 5. 1 GWh and further declining to 4. Solar panels peak at noon, but demand surges at 7 PM - that's where battery storage systems become crucial.
