According to the companies, the Rizziconi project addresses conditions in southern Italy where increasing solar generation frequently surpasses grid absorption capacity by midday.
Battery systems that store excess generation and release it during later periods are essential for managing this dynamic. Calabria has historically experienced higher electricity costs and less robust grid connectivity compared to northern Italy, making local flexibility valuable.
The project also marks e-Storage’s first project in Italy, and the companies intend to continue working together, forming a “broader relationship”.
Italy’s energy storage capacity was expanded last year. On 1 October 2025, transmission system operator (TSO) Terna announced the results of the country’s energy storage-focused capacity auction scheme, the Meccanismo di Approvvigionamento di Capacità di Stoccaggio Elettrico (MACSE), procuring 10GWh of energy storage capacity for Italy.
E-Storage and Axpo have both previously been active in Europe. In December 2023, e-Storage signed a deal with international utility and independent power producer (IPP) Engie for two separate 50MW/100MWh BESS projects in the UK.
