Aer Soléir today announced the finalization of a fixed toll agreement with its partner EGO Energy S.r.l. (“EGO Energy”), a direct subsidiary of Shell Italia Holding S.P.A. and one of the fastest growing energy management companies in Italy. This agreement is among the largest battery energy storage system (BESS) offtake deal completed in Europe to date and marks a major milestone in Aer Soléir’s mission to deliver best-in-class renewable energy infrastructure across the continent.

Under the agreement, EGO Energy will trade and operate the Rondissone BESS asset as part of its renewable energy portfolio. In exchange, EGO Energy will make fixed annual payments to Aer Soléir. This revenue stream, in addition to Rondissone’s 15-year Capacity Market Contract awarded by the Italian government, secures 100 percent of the asset’s revenue for the first seven years of its operational life.

Rondissone is Aer Soléir’s flagship battery storage project. At 250 MW with a 4-hour duration, it is the largest battery storage project currently under construction in Italy. Located in Piedmont, within the Italy Nord Power Zone, the project represents a capital deployment by Aer Soléir of more than €150 million and is the first step in Aer Soléir’s €1.5 billion capital deployment plan across its 17 wind, solar and battery storage projects in Italy over the next five years.

The Rondissone project secured the 15-year Capacity Market Contract with the Italian Government in the Q1 2025 auction at €47,000 per MW per year, generating over €115M in revenue over the contract tenor. Under this agreement, Rondissone will provide flexible capacity to support the Italian power grid in exchange for fixed annual payments.

Andy Kinsella, Founder and CEO of Aer Soléir, said: “We are delighted to announce this landmark collaboration with EGO Energy. This agreement further enhances Aer Soléir’s reputation as a provider and supplier of best-in-class renewable energy projects and as an attractive corporate offtake partner for blue-chip global corporations. This breakthrough project is also a testament to the strength of our partnership with Quantum Capital Group and 547 Energy, whose support enables us to deliver high-impact, sustainable infrastructure across Europe.”
