De Gaulle Fleurance advises the banking pool on the financing of a hybrid power station designed to secure the electricity supply in eastern French Guiana

Deals 30 July 2026

De Gaulle Fleurance has advised the banking consortium comprising Bpifrance, BRED Banque Populaire, Caisse d’Épargne CEPAC and Crédit Agricole Transitions & Énergies on the financing of the Sainte-Anne hybrid power station, developed by Voltalia in French Guiana. This project constitutes a strategic piece of infrastructure designed to strengthen the security of the electricity supply in the western part of the territory whilst promoting the development of low-carbon energy generation.

Developed by Voltalia, a French renewable energy company established in French Guiana in 2005, the Sainte-Anne hybrid power station, located in the commune of Mana, near Saint-Laurent-du-Maroni, will combine 43 MW of photovoltaic panels with a lithium-ion battery storage system with a capacity of 135 MWh, as well as five backup generators running on biofuel (HVO[1] ), representing a total capacity of 7 MW. This combination of renewable energy, storage and controllable generation will ensure the continuity of the electricity supply whilst optimizing the integration of solar energy into the network.

The power station will generate nearly 50 GWh of electricity per year, equivalent to the electricity consumption of around 50,000 residents. Site preparation work began in July 2025, and construction is ongoing with a view to commissioning in 2028. This project also benefited from a national crowdfunding campaign that was successfully concluded in April 2026, demonstrating strong local support for the region’s energy transition.

In a backdrop of energy transition and efforts to strengthen the resilience of electricity networks in non-interconnected regions, this hybrid power station addresses the challenges of security of supply and decarbonizing electricity generation. It also illustrates the development of innovative energy models combining renewable generation, storage and flexible generation capacity.

Long-term financing of over €120 million was provided by Bpifrance, BRED Banque Populaire, Caisse d’Épargne CEPAC and Auxifip as lenders, and by Bpifrance, BRED Banque Populaire, Caisse d’Épargne CEPAC and Crédit Agricole Transitions & Énergies as arrangers.

De Gaulle Fleurance (Sylvie Perrin, partner; Claire Haas, senior counsel; Noé Fontalba, senior manager; Béatrice Boisnier and Hugo Nougarolis, lawyers) acted alongside the banking syndicate in structuring and negotiating the financing documentation for this transaction. This financing demonstrates the vital role played by banks in supporting the energy infrastructure required for the energy transition and for securing electricity networks.

Sylvie Perrin, partner at De Gaulle Fleurance, said: “We are delighted to have supported the banking syndicate in financing this hybrid power station, which exemplifies the development of innovative energy solutions that balance security of supply, economic performance and the energy transition. This project demonstrates the growing role of hybrid infrastructure in the transformation of electricity systems.”
