Voltalia (Euronext, Paris), international player in renewable energies, has announced the commissioning of the Mana battery storage power plant with a capacity of 10 megawatts / 13.6 megawatt hours. The power plant will reinforce the Toco storage complex. Located in French Guiana, the Toco complex is the largest storage system in France, with 12.6 megawatts / 16.5 megawatt hours in operation and 0.5 megawatts / 0.6 megawatt hours under construction.

“With 29 megawatts in operation and under construction in French Guiana (biomass, hydroelectricity, ground and roof-mounted solar power, storage) Voltalia is a key player in the local energy landscape. Its activity also has a structuring effect on the economy, particularly in the biomass sector, which is at the heart of a strategic sector for French Guiana. Our new storage facility makes it possible to take advantage of renewable energies even when climatic conditions do not allow production. In French Guiana, thanks to the drop in the cost of renewable technologies and batteries, it is now possible to avoid burning polluting fossil fuels that are more expensive than renewables. I would like to warmly thank our teams who, despite numerous difficulties due to the sanitary context, have successfully built the largest battery storage system in France” said Sébastien Clerc, CEO of Voltalia.

A second battery storage project in the Toco storage complex, the largest in France after the Savane des Pères1 power plant, with its 2.6 megawatt / 2.9 megawatt hour battery storage system backing a 3.8 megawatt solar power plant, the Toco complex is expanding with the commissioning of the Mana storage power plant, and its 10 megawatt / 13.6 megawatt hour batteries.

Entirely developed by Voltalia, the Toco complex thus becomes the largest battery storage system in operation in France. An additional 0.5 megawatt / 0.6 megawatt hour unit is currently under construction. Thanks to its accumulated expertise and economies of scale, Voltalia plans to continue its strategy of growing the Toco complex with additional units that will be added to the system.

The Mana storage facility is named after the municipality in which it is located. The main winner of a call for projects from the French Energy Regulatory Commission (CRE) in 2018, Mana Stockage benefits from 10-year remuneration contracts. This project is supported by the European Regional Development Fund (ERDF).
