GreenGo has secured authorisation for the 120MW San Sostene battery storage project in Calabria, bringing its total approved storage capacity to 249MW.
The Bologna-based developer said San Sostene will deliver 480MWh of capacity and connect to the 150kV SE San Sostene node, charging during peak renewable availability and discharging at peak demand.
The company added that with the new approval its entire battery pipeline is now authorised, with 998MW eligible for the first MACSE auction in the south and Sicily.
GreenGo said San Sostene was acquired in 2024 and reached full approval within 18 months, including 13 months from the initial application.
The company noted that 200MW of storage has been authorised in the last six months.
Business development and M&A director Alberto Piva (pictured) said: “San Sostene is a clear example of how an M&A transaction, guided by a vision of industrial development, can generate concrete value in a short time.
“In just over a calendar year, we obtained the Single Authorisation, transforming the investment into a strategic asset perfectly positioned on the network.
“This result confirms the soundness of our approach to scouting and execution, while strengthening GreenGo’s competitive positioning ahead of the MACSE auctions.”
CTO and partner Fabio Amico said: “With San Sostene, we are consolidating GreenGo’s presence in the storage sector, bringing the total of BESS projects already authorised to around 250MWp and strengthening our ability to participate in the first round of MACSE.
“This result demonstrates not only the speed and efficiency of our technical and authorisation teams, but also the industrial vision that guides us in the development of strategic energy infrastructure and storage.”
GreenGo said it has expanded its storage portfolio to over 400MW in less than two years, more than half of which are authorised projects.
The project is among the first approved through Italy’s new digital ministerial permitting portal.
GreenGo said its overall pipeline now stands at 1.73GW across 75 projects in 12 regions, with 693MW authorised or ready-to-build and 40MW under construction.
