We are repowering Claudia, our battery energy storage facility located in Saucats (France).<\/strong><\/p>\n\n

Originally designed as a 1 hour BESS, Claudia is now being upgraded to 2 hours of storage, doubling its energy capacity and significantly increasing its value for the power system!<\/p>\n\n

Why does it matter? Because as renewables grow, flexibility becomes just as critical as production. Longer-duration storage means better frequency control, improved balancing, and readiness for advanced grid services like grid-forming.<\/p>\n\n

In practical terms, the site evolves from 105 MW \/ 100 MWh to 94 MW \/ 188 MWh, extending the asset\u2019s lifetime while reusing existing infrastructure: a strong example of how repowering can combine performance and sustainability.<\/p>\n\n

This project is also built on solid foundations: a hybrid battery architecture (NMC & LFP) to maximize safety and resilience, and a long-term public-private partnership with Caisse des D\u00e9p\u00f4ts joining the project alongside Amarenco. The debt is carried by Soci\u00e9t\u00e9 G\u00e9n\u00e9rale and Rabobank.<\/p>\n\n

Claudia also benefits from a long-term operating framework that provides Amarenco with strong visibility on future revenues, through a tolling agreement provided by ENGIE. This structure strengthens the asset\u2019s financial robustness and confirms the economic relevance of large-scale storage infrastructure. <\/p>\n\n

First battery deliveries are expected in spring 2026, with commercial operation planned for early 2027.<\/p>\n\n

Claudia represents more than ever a key step in building Amarenco\u2019s European storage platform to support the next phase of the energy transition.<\/p>\n","protected":false},"excerpt":{"rendered":"
