Larivot bioenergy power plant: VINCI Energies in synergy mode
Reading time: 3 min
The Larivot site in French Guiana is to replace the current Dégrad des Cannes power plant. This is a major project crucial to French Guiana’s economy, involving several VINCI Energies business units. The primary challenge is to meet the completion deadline so the new plant can be commissioned in 2026.
With guaranteed power of 120 MW, the new Larivot bioenergy plant is due to replace the current Dégrad des Cannes plant in 2026 to secure the electricity supply in French Guiana. This strategic facility will be powered by liquid biomass obtained from vegetable oils such as rapeseed, a 100% renewable biofuel from sustainable supply chains excluding soybean and palm oil.
Equipped with seven next-generation motors, the Larivot plant will be able to adjust its power and energy according to the region’s changing means of production and the population’s energy requirements. EDF Production Electrique Insulaire (EDF PEI), an EDF group subsidiary involved in energy transition for island territories, entrusted two of the project’s three batches to two consortiums – one led by VINCI Construction Grands Projets and the other by Omexom Major Projects.
Extra-high-voltage synergy
“For this project, VINCI Energies has mobilised several business units specialised in extra-high voltage for their know-how and expertise to meet the needs and expectations of EDF (EDF PEI and EDF SEI Guyane),” explains Adel Farouil, Project Manager at Omexom Major Projects.
“VINCI Energies has mobilised several business units specialised in extra-high voltage for their know-how and expertise.”
In partnership with Nofrayane (VINCI Construction), Omexom Major Projects is responsible for construction of the HV indoor modular substation, which will transfer energy from the power plant to the EDF SEI Guyane network. This substation will become a strategic component in French Guiana’s electricity system. Omexom Major Projects is also contributing to the installation and HV/MV connection of the plant’s seven power transformers.
SDEL Contrôle Commande is handling design studies, fabrication and commissioning of the control cabinets for the energy output station. Omexom THT Antilles Guyane is creating the overhead and underground HV lines to connect the HV substation to the EDF SEI Guyane network.
In short, this major project in French Guiana required VINCI Energies to mobilise an entire ecosystem to meet the completion deadline so the Larivot plant can be commissioned in 2026.
