The first photovoltaic power plant in France and the largest floating solar power plant in Europe has been opened in Piolenc, a commune of 5,000 inhabitants in the department of Vaucluse (84). This groundbreaking project was realised by Bouygues Energies & Services, a subsidiary of Bouygues Construction.  

With almost 50,000 photovoltaic panels floating on a former quarry converted into an artificial lake, this plant will produce the equivalent of the electricity consumption of the commune of Piolenc every year (17 megawatts-peak) and will supply the electricity for over 4,700 households.
