Production multiplied by five with four times fewer wind turbines : TotalEnergies inaugurated the completely renovated La Perrière wind farm on July 8 in Sainte-Suzanne., after the dismantling of the old wind turbines. This new generation park limits its environmental impact as much as possible and contributes significantly to Reunion Island’s energy transition strategy..
Commissioned between 2005 and 2007, the La Perrière wind farm was the first of its kind in Reunion Island. Made up of 37 folding Vergnet wind turbines, l produced 10 GWh by the, i.e. the equivalent of the consumption of 7,100 inhabitants. End of life arrivals in 2021, these wind turbines were dismantled in compliance with environmental standards, with a material recovery rate greater than 90%. The operation was carried out in particular with a view to preserving the endemic fauna of the site., notably the green lizard of the Hauts, protected species and carefully relocated under the supervision of ecologists. The land was entirely returned to its natural state before the reconstruction phase initiated in 2022.
Consumption of 35,000 inhabitants
The modernization of the park allowed the installation of nine wind turbines of 2,2 MW each, bringing the installed power to 19,8 MW. Thanks to this latest generation equipment, production is multiplied by five, attractant 50 GWh par the, i.e. the equivalent of the consumption of 35,000 inhabitants and an annual saving of 40,000 tonnes of CO2. One of the strengths of the project also lies in the integration of batteries, allowing part of the electricity to be stored and released later, according to needs. This storage system helps stabilize the network by ensuring regular injection of the electricity produced.. This new park is part of the objectives of the multi-annual energy program (PPE), which provides 91,5 MW installed in wind power by 2028. This achievement mobilizes local businesses, whether in the construction phase, operation or maintenance.
A project designed with respect for biodiversity
The new wind turbines are equipped with an avifauna detection system, capable of identifying the trajectory of birds and triggering light and sound signals to avoid collisions. Reinforced environmental monitoring has been put in place, supplemented by support for the national action plan in favor of papangue, endemic raptor of the island.
