Terna's thinking The date is set. The first of Italy's new energy storage capacity procurement auctions (MACSE) will take place on September 30, 2025, Terna's president for grid development strategies, Francesco Del Pizzo, has confirmed.
There are stark differences in energy storage requirements across Italy and MACSE procurement targets will adapt to these zonal needs. Most of the new utility-scale storage capacity catalyzed by MACSE will be needed in Southern Italy and the islands, with 16.8 GWh in the South, 13.6 GWh in Sicily, and 10.4 GWh in Sardinia.
The mechanism, offering 15-year contracts on up to 100% of asset capacity, aims to support the installation of energy storage necessary to achieve the country's renewable energy target of 131 GW by 2030.
Most of the need for new utility-scale storage capacity is concentrated in Southern Italy and the islands, with 16.8 GWh required in the South, 13.6 GWh in Sicily and 10.4 GWh in Sardinia. Aurora's detailed analysis highlights the MACSE mechanism's ability to attract significant investments in energy storage, balancing risks and returns.
