Wedoany.com Report-Aug. 26, GreenGo has received authorisation for the 120MW San Sostene battery storage project in Calabria, bringing its total approved storage capacity to 249MW. According to the company, the San Sostene facility will deliver 480MWh of storage capacity and connect to the 150kV SE San Sostene node. It will charge during periods of high renewable energy availability and discharge at times of peak electricity demand, providing flexibility to the regional grid.

The Bologna-based developer highlighted that with this latest approval, its entire battery storage pipeline is now authorised, with 998MW eligible for participation in the first MACSE auction in southern Italy and Sicily. GreenGo explained that the San Sostene project was acquired in 2024 and achieved full approval within 18 months, including 13 months from the submission of the initial application. The company also noted that 200MW of storage capacity has been authorised in the last six months, underscoring the pace of development in its portfolio.

Alberto Piva, business development and M&A director at GreenGo, 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.”

Fabio Amico, CTO and partner at GreenGo, added: “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.”

The company stated that it has expanded its storage portfolio to more than 400MW in under two years, with over half of that capacity now authorised. The San Sostene project is among the first to receive approval through Italy’s new digital ministerial permitting portal, marking a step toward more efficient regulatory processes.

GreenGo further reported that its overall project pipeline currently stands at 1.73GW across 75 projects in 12 regions of Italy. Within this pipeline, 693MW has either been authorised or reached ready-to-build status, while 40MW is already under construction. These figures indicate steady progress in advancing energy storage capacity, aligning with broader efforts to strengthen electricity system flexibility and integrate renewable energy sources.

By advancing projects such as San Sostene, GreenGo is reinforcing its position in Italy’s energy storage sector and preparing to play an active role in upcoming market mechanisms, while contributing to the development of more resilient and adaptable energy infrastructure.
