Floating photovoltaics deployed in a quarry in France – PV Magazine International


Sorégies built a 2.7 MW floating photovoltaic generator in a quarry in Nouvelle-Aquitaine, France.

By pv magazine FranceSergies, the renewable energy unit of Sorégies, has completed a 27 MW floating photovoltaic field on a flooded quarry in Saint-Maurice-la-Clouère, in Nouvelle-Aquitaine, France.

The factory was built by the French entrepreneur GSM. Panel manufacturer based in France VMH Energies supplied the PV modules. The project was built on a former quarry owned by GSM.

The solar panels, assembled by VMH in Châtellerault, are completely removable and recyclable. The electrical engineering work – as well as the installation of structures and modules – was carried out by Bouygues Energies Services, a subsidiary of the French conglomerate Bouygues SA. The floating structures were provided by Ako Industries, while Novanautic / Nautischaphe took care of the installation and anchoring.

This plant will produce more than 3.3 GWh of electricity per year, Sergies said. The total cost of the project is 3 million euros ($ 3.5 million).

Residents of several local municipalities supported the project with a crowdfunding effort last summer on the Lumo platform, raising € 150,000. About a hundred subscribers took part in the initiative. Projects built with a certain percentage of crowdfunding funding also benefit from an additional incentive in addition to that granted under the country’s tendering system.

If all of France’s man-made lakes housed photovoltaic systems, they could cover the needs of 3 million homes – including heating and hot water, Sergies said.

In June 2019, the Compagnie Nationale du Rhône (CNR) unit of French energy giant Engie inaugurated its first floating solar power plant, on Lac de la Madone, in the Rhône department, in the south of France. Later in March this year, CNR said it had started planning a 30 MW floating grid in the municipality of Châteauneuf-du-Rhône, in the Drôme department.
