Floating solar panels on a quarry lake
Piolenc is the very first project developed by Laketricity (formerly Multimega, the development arm of the Ciel & Terre group). It is also the first French floating solar pilot, installed on the company’s own initiative.
The project was developed in collaboration with Akuo, who remained active during the development phase and made a significant contribution to the engineering of the project. The floating solar power plant is now operated by Akuo.
This installation was made possible thanks to the surface area offered by the quarry lake to accommodate floating solar panels. The town of Piolenc was thus able to reduce its carbon footprint, with 1,093 tonnes of CO2 avoided in the first year thanks to the production of renewable energy. In terms of equivalent energy consumption per household in France, the Piolenc project generates energy for more than 4,700 households.
After several years of project development and commissioning, the floating solar panels were able to generate electricity in Piolenc. The renewable energy produced is fed into the grid.
