October 24, 2025: Battery storage capacity in Italy surged more than 55% year-on-year toward the end of summer, totalling over 17GWh, according to latest data. Italian transmission system operator Terna said on September 19 the storage capacity, recorded as of August 31, was equivalent to 7MW of. Battery Energy Storage Systems (BESS), or electrochemical batteries, are currently the leading solution for storing electricity and are essential to the development of clean energy: the Enel Group is at the forefront of technological innovation in this sector too. Energy storage systems are now. Airengy has announced that Italy's national transmission system operator TERNA has given permission for the grid connection of the company's lithium-ion battery energy storage system (BESS) in the Brindisi region of Italy. The lead and lithium manufacturer, whose Italian operations are based in the province of Bergamo, said on August 26 it had delivered its Solition Mega Three. In 2025, Eni executed a strategic pivot from a traditional energy producer to a vertically integrated manufacturer in the energy storage supply chain, a fundamental shift from its pre- 2025 position as primarily a deployer and operator of energy assets. This move is designed to capture value. ing ground to build operational expertise in a technology that we expect will increasingly become part of our development plans. The pla t will be managed using partly in-house developed digital tools, leveraging our experience in the management of flexible assets.
