Italy has taken a major step forward in its energy transition efforts, giving the green light to 361 MW of new battery energy storage systems (BESS) spread across three regions—Lazio, Puglia, and Sardinia. This move underscores the country’s growing commitment to grid resilience, energy independence, and renewable integration through the deployment of commercial and industrial energy storage solutions.
Final approvals were issued by Italy’s Ministry of the Environment and Energy Security (MASE) on August 5th, delivered through multiple Decreti Direttoriali (Directorial Decrees). These formal authorizations represent the culmination of the “Autorizzazione Unica”—a simplified national permitting process designed to accelerate energy infrastructure development by consolidating all necessary permissions into one administrative act. With these approvals now in place, developers can officially move forward with construction.
A Diverse Portfolio Across Italy
The headline project among the newly approved developments is the 160 MW Roverella BESS, to be constructed in Tuscania, a historic town in the province of Viterbo, central Italy. Spearheaded by Sphera Zefiro Srl, this facility will serve as a key node in bolstering grid stability in the Lazio region—strategically positioned between the densely populated cities of Rome and Siena.
The remaining projects vary in size and regional significance:
- 72 MW BESS in Mogorella, Sardinia – developed by Mogorella Srl, this marks a noteworthy advancement for the island’s energy infrastructure, which has long faced challenges due to its geographic isolation.
- 54.4 MW BESS in Santeramo in Colle, Apulia – awarded to Jupiter Srl, this project adds crucial storage capacity in one of Italy’s sunniest regions, rich in solar PV resources.
- 50 MW “Stornara” BESS in Foggia, Apulia – developed by Atlas Storage 5 Srl, the project reinforces the southern grid’s capacity to absorb excess renewable production.
- 25 MW “Malone” BESS in Ceprano, Lazio – by GreenStore 4 Srl, further enhances the region’s decentralized energy strategy.
While detailed specifications such as storage duration (in MWh) are not typically disclosed in the permitting stage, these BESS projects are expected to deliver critical grid services including frequency regulation, peak shaving, and balancing of intermittent renewables—particularly solar and wind.
Why This Matters for Italy—and Europe
These developments arrive at a pivotal moment. Italy, like much of Europe, is undergoing a rapid transformation in how it generates and distributes energy. With solar PV and wind power ramping up quickly, grid operators are increasingly reliant on energy storage systems to manage variability and avoid curtailment of renewable energy during periods of oversupply.
Italy’s national energy and climate plan (PNIEC) outlines ambitious targets for decarbonization and aims to reach around 70 GW of solar and 18 GW of wind capacity by 2030. Realizing this vision will require a parallel surge in C&I ESS and utility-scale storage to ensure energy security, grid stability, and affordability.
Moreover, the deployment of commercial and industrial energy storage systems also helps decentralize energy management—empowering local communities and businesses to participate actively in the energy transition.
The Road Ahead: Storage as a Strategic Asset
The approval of these 361 MW represents not just regulatory progress, but a broader market signal. Developers now have three years to complete construction, setting the stage for Italy’s energy storage capacity to expand significantly in the near term. In tandem with similar developments across Europe, Italy’s push is contributing to the maturation of the continent’s storage market—where flexibility is fast becoming as critical as capacity.
As storage technologies continue to evolve and costs decline, industry observers expect more BESS projects to move from paper to reality. The challenge now lies in ensuring adequate grid integration, streamlining further permits, and fostering the right investment climate to support this growth trajectory.
For Italy, these latest approvals are more than just infrastructure projects—they’re foundational pieces in a cleaner, more resilient, and smarter energy system. And for Europe at large, they offer a compelling case study in how battery storage is no longer an option, but an essential component of the energy future.
