Paris, December 2025 - Astris Finance congratulates its client Amarenco, a leading Irish-based solar IPP, for the raise of a €65m debt facility for the repowering and refinancing of a battery storage asset located in southwestern France (“Claudia”). This transaction also marks the start of a long-term partnership with Banque des Territoires, the investment arm of State-owned Caisse des Dépôts.

Originally designed as a 1-hour BESS, Claudia is now being upgraded to 2 hours of storage, doubling its energy capacity - from 105 MW / 100 MWh to 94 MW / 188 MWh -, significantly increasing its value for the power system and extending the asset’s lifetime while reusing existing infrastructure. First battery deliveries are expected in spring 2026, with commercial operation planned for early 2027.

The transaction was arranged and financed by Société Générale and Rabobank.

Astris acted as exclusive financial advisor to Amarenco. This transaction is Astris’s fifth closing with Amarenco over the past 3 years and an additional credential in the very dynamic European BESS space.
