Voltalia, an international player in renewable energies, announces the start of commissioning of its 10.5-megawatt biomass power plant in Sinnamary. This new facility complements the existing plants in Kourou (1.7 megawatts) and Cacao (5.1 megawatts), which are already operational in French Guiana.
The first boiler ignitions, a key milestone in the commissioning process of the Sinnamary biomass power plant, took place in early April 2025. This initial phase marked the beginning of technical tests. The largest biomass power plant in French Guiana, currently in its final testing phase before full commissioning, will be able to meet up to 8% of the territory’s electricity needs.
Located on the Petit Saut site, the biomass plant has an annual production capacity of over 80 gigawatt-hours. This project is part of a broader initiative to harness local resources and contribute to the diversification and decarbonization of the region’s energy mix.
With the commissioning of the Sinnamary power plant, Voltalia is reaching a new milestone by doubling its local generation capacity. The company will now have a production capacity equivalent to approximately 16% of the territory’s electricity consumption, further strengthening its role as a key player in the energy transition in French Guiana.
