Alsace Launches First Large-Scale Floating Solar Plant

Jan 16, 2025 01:42 PM ET
  • Leutenheim's pioneering 20-MWp floating solar plant transforms a gravel pit into renewable power, generating enough energy for 7,250 homes while showcasing cutting-edge technology and sustainability.

A 20-MWp floating solar plant has been installed in Leutenheim, Alsace, marking the region's first large-scale floating photovoltaic project. Developed over five years by French independent power producer Generale du Solaire, in partnership with floating solar specialist Ciel & Terre, the plant will generate approximately 21,750 MWh of electricity annually, enough to power 7,250 homes. The project repurposes a former gravel pit, with the site owned by the municipality while Generale du Solaire oversees development and operations.

Ciel & Terre utilized its advanced Hydrelio aiR Optim technology to optimize electricity production from the floating structure, addressing technical challenges due to varying water levels. Having participated in over 325 floating solar projects worldwide, Ciel & Terre's expertise contributed to the successful execution of this innovative solar installation, which represents Generale du Solaire's first venture into floating solar energy projects in France.
