BW ESS and ACL Energy Expand Italian BESS Partnership

BW ESS and ACL Energy have announced a significant expansion of their joint project development pipeline for stand-alone, utility-scale battery energy storage systems (BESS) in Italy. Building on their initial partnership established in February 2024 – which included three projects totalling 0.4 GW – the two companies now commit to co-developing an additional eleven projects with a substantial 2.5 GW of capacity. 

This expansion brings the total development pipeline managed by the BW ESS and ACL Energy partnership to 14 projects, representing 2.9 GW of capacity across Italy's North and South electricity zones. All projects have secured land and grid access and are advancing towards obtaining permits. Notably, seven of these projects totalling over 1 GW are already undergoing review by the Ministry of Environment and Energy Security (MASE). Northern projects will target participation in the capacity market scheme, while Southern projects aim to bid in the Mechanism for Procuring Electricity Storage Capacity (MACSE).

The partnership’s growth aligns with Italy’s accelerating renewable energy expansion, and thus need for energy storage. According to Terna , the Italian transmission system operator, the country added 2.9 GW of wind and solar capacity in 2022, 5.7 GW in 2023, and another 5.4 GW in the first nine months of 2024. The scale of BW ESS and ACL Energy’s collaboration underscores their shared belief in the critical role of BESS in Italy’s transition to a sustainable energy future.

Roberto Jiménez, Executive Director of BW ESS, stated: "Deepening our partnership with ACL Energy allows us to significantly scale our development activities in Italy. We believe our shared pipeline represents one of the largest among non-utility players in the Italian BESS market. We're excited to contribute to the country’s energy transition by bringing substantial battery storage capacity online."

Nicola Locascio, Managing Partner of ACL Energy, added: "We are proud to strengthen our partnership with a global leader like BW ESS, whose expertise in energy storage is invaluable. This collaboration is a cornerstone of our medium- and long-term strategy, reinforcing ACL Energy’s ambition to lead in Italy’s rapidly growing energy storage sector."

ACL Energy was advised by Eversheds Sutherland, while BW ESS received counsel from Bird & Bird, with technical advisory support from Kiwa Moroni.
