Trade body Italia Solare has processed data from electricity transmission system operator (TSO) Terna, which shows that independent storage is the biggest new market development.

According to the Italian PV association Italia Solare, Italy had 650,007 grid-connected energy storage systems at the end of June 2024, with a total of 4.5 GW of nominal capacity.
“During the first half of 2024, 126,916 storage systems were connected in Italy, with a total capacity of 1.05 GW and a capacity of 2.63 GWh,” Italia Solare wrote in comments on TSO Terna data.
The data shows that the number of storage systems increased by 24.6% in the first half of 2024, while their total rated capacity increased by 30.4%, indicating that systems are becoming increasingly larger.
About 58%, or 1.55 GWh, of the energy storage capacity connected in the first half of 2024 “is attributable to storage facilities with a capacity of less than 50 kWh related to photovoltaic systems,” wrote Italia Solare, and added: “About 2% (48 MWh) is attributable to storage facilities with a capacity of more than 50 kWh associated with photovoltaic systems and, this is the novelty, 39% (1.04 GWh) is instead related to six standalone storage facilities of which 35% is attributable to a single 200 MW (805 MWh) system connected in Piacenza.”
Commercial and industrial (C&I) energy storage systems in Italy still have a capacity of just 108 MWh, the trade body said, but the segment is growing, with 44% (48 MWh) of that total connected in the first half of 2024.
The Lombardy region, with a storage capacity of 1,454 MWh, is the leader in Italy in energy storage systems connected to solar photovoltaic energy. It is followed by Veneto, with 1,081 MWh; Emilia-Romagna, with 749 MWh; Lazio, with 577 MWh; and Piedmont, with 568 MWh. The connected capacity in these five regions accounts for more than 55% of the country’s solar-connected storage.
