Voltalia Starts Construction of 43 MW Hybrid Solar-Storage Power Plant in French Guiana, Targeting 2028 Commissioning

The hybrid facility features a 43 MW photovoltaic installation paired with a lithium-ion battery system capable of delivering 34 MW of power and storing 135 MWh of energy. This configuration will enable the plant to stabilize intermittent solar output and provide reliable electricity despite the grid’s frequent strain in western French Guiana. Additionally, the plant incorporates seven megawatts of HVO1 biofuel-powered generators, which will only be deployed in extreme emergencies to support the grid, further enhancing supply reliability in this remote region. Located near the EDF source substation at Carrefour Margot, the site facilitates smooth integration into the existing electricity infrastructure. The plant is expected to produce approximately 50 gigawatt-hours annually, covering the energy needs of roughly 50,000 residents and cutting carbon dioxide emissions by an estimated 45,300 tons each year. Voltalia emphasizes the design’s adaptability to local climatic conditions such as heavy rainfall and elevated temperatures, and the facility has been developed for future scalability in both generation and storage capacity. Site preparation began in July 2025, with construction scheduled over a three-year period and commissioning planned for 2028. The project aligns with French Guiana’s Multi-Year Energy Program (PPE) and the territory’s push for energy independence by reducing reliance on costly imported fossil fuels. Voltalia, an international renewable energy producer with over 3.3 gigawatts in operation and construction worldwide, will manage the full development cycle from construction to operation. This project underscores Voltalia’s growing footprint in French Guiana and its commitment to advancing sustainable energy infrastructure in isolated tropical environments.
