Amarenco acquires 100% of Énergie Développement

Amarenco acquires 100% of Énergie Développement, its long-standing joint venture with TotalEnergies Renouvelables France

With this transaction, Amarenco becomes the sole shareholder of this entity, which was established in 2017, and takes a further step forward in its development as a fully integrated European Independent Power Producer.

By taking full ownership of this multi-segment portfolio of solar assets, which is particularly well-established in the South-West, we are consolidating our position as an IPP and strengthening the predictability of our revenues.

This acquisition also marks the culmination of a successful partnership with TotalEnergies, Amarenco’s long-standing partner in the development of solar energy in France!

It is also a key step towards achieving our ambition: to reach, within 24 months, 1 TWh of annual generation, 1 GW of installed capacity and full structural financial independence.

Amarenco launches construction of Osmo

Amarenco launches construction of Osmo, a new 100 MW / 2-hour BESS project in France!
After Claudia, Osmo marks another major step in our commitment to energy storage and grid flexibility.

The energy transition is really about building the infrastructure needed to make the power system more stable, secure and resilient. Located between Os-Marsillon and Mourenx, in the Lacq industrial basin, Osmo is a 100 MW Lithium-Ion LFP battery energy storage project with a 2-hour capacity.

By investing for more than four years in these strategic infrastructures, Amarenco continues to anticipate the needs of the French electricity system and support RTE with essential services.

The project’s location was also a key choice. By developing on a former industrial site, close to existing infrastructure and with optimal grid connection conditions, Osmo helps limit the environmental footprint of the project while adding new value to an underused land area.

This project is supported by a strong ecosystem of industrial and local partners, and we are delighted to have finalized the financing of this project with our partner Société Générale and are now fully focused on launching its construction

With this closing, the Group confirms the acceleration of its energy storage project portfolio in France and across several European countries.

A huge thank you to our partners and internal teams for helping move forward this strategically important project!

Amarenco Vivescia Partnership

A strategic alliance serving local communities

We are pleased to announce this partnership, with the priority launch of 8 ground-mounted photovoltaic power plant projects representing a total cumulative capacity of 15 MWc on agricultural storage sites. This alliance is part of a strategic initiative aimed at regenerating natural and living spaces as part of our ECHO Program and energy transition efforts.

In practical terms, this first phase will enable the production of local renewable energy, directly aligned with local needs, while limiting soil artificialization thanks to the low land footprint of the proposed reversibility solutions.

We share with VIVESCIA a long-term vision: combining energy performance, territorial anchoring, and the transition toward agricultural and agro-industrial sectors. Thank you to the committed teams on both sides for their trust and mobilization around this structuring project!

Let’s talk about storage With ENEDIS

A day of strategic discussions with ENEDIS at our Saucats storage facility!

We were pleased to welcome the managers and members of the Executive Committee of Enedis Aquitaine Nord to Saucats, home to Claudia, one of Europe’s largest storage units, developed by Amarenco. It was a busy, productive day—and, above all, one that was closely aligned with current challenges.

Their feedback speaks for itself:

  • “Unanimously very positive” discussions
  • A better understanding of the role of storage in the power system
  • Transparent discussions on market realities, both in France and across Europe

Storage is a strategic lever for grid operators: it contributes to grid regulation, congestion relief, and, ultimately, the optimization of their day-to-day operations.

For ENEDIS, the challenge was to better understand the potential of services provided to the power system in relation to connection requests.

For AMARENCO, the challenge was to share our expertise, concretely demonstrating our mastery of these technologies.

A mission 100% accomplished!

Thank you to the Enedis teams for their commitment and the quality of our discussions, And thank you to our teams for their unwavering dedication

Amarenco secures a €130 million preferred equity tranche

Amarenco obtient un preferred equity de 130 millions d’euros auprès de Arjun Infrastructure Partners pour accélérer sa croissance européenne.

Amarenco secures a €130 million preferred equity tranche from Arjun Infrastructure Partners to accelerate its European growth.

This strategic investment, completed with our long-standing shareholder Arjun Infrastructure Partners, an important milestone in the next phase of our development: it reinforces our integrated IPP platform and supports our clear trajectory toward structural financial autonomy.

Within the next 24 months, we are targeting a key threshold, exceeding 1 TWh of annual production, backed by more than 1 GW of installed capacity, a decisive step toward a fully integrated IPP model generating recurring EBITDA from energy production and asset rotation. 📈

In 2025, we delivered more than 600 GWh of clean electricity and reached 650 MW of installed solar capacity, a clear demonstration of our execution capabilities and long-term vision. Our growing portfolio also includes 94 MW / 188 MWh of storage capacity, contributing to grid resilience while generating additional value through energy trading.

As we grow, we remain committed to our regenerative approach, embedding soil restoration and biodiversity enhancement at the heart of our projects.

Thank you to our teams, partners and investors for their continued trust! ☀️

Repowering Claudia

We are repowering Claudia, our battery energy storage facility located in Saucats (France).

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!

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.

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

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 Dépôts joining the project alongside Amarenco. The debt is carried by Société Générale and Rabobank.

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’s financial robustness and confirms the economic relevance of large-scale storage infrastructure.

First battery deliveries are expected in spring 2026, with commercial operation planned for early 2027.

Claudia represents more than ever a key step in building Amarenco’s European storage platform to support the next phase of the energy transition.
