In French Guiana, Commissioning of a Combined Solar and Storage Power Plant

Voltalia (Euronext Paris, ISIN code: FR0011995588), an international player in renewable energy, announces today the commissioning of its Sable Blanc power plant combining photovoltaic production, with a capacity of five megawatts, and battery storage, with a capacity of 10.6 megawatt hours.

Developed entirely by Voltalia, the Sable Blanc mixed plant will benefit from a guaranteed sales price for 20 years.

The photovoltaic production capacity will cover the equivalent of the electricity needs of 3,090 inhabitants of Western Guiana.

The lithium-ion batteries allow the electricity produced during the day to be injected after night fall, while improving the stability of electricity production in a region with high demand.

These batteries strengthen the Toco storage complex, which now has a capacity of 19 megawatts and 27 megawatt hours.

With a strong presence in French Guiana, Voltalia currently operates solar, hydro, biomass and storage power plants with a combined capacity of 48 megawatts, covering almost 10% of the consumption of the main electricity grid.
