- The Pierrières solar farm comprises 7,420 solar modules with an installed capacity of 3.37 MWac.
- The facility will supply green electricity to approximately 1,500 households.
- Located on a former landfill site, the Pierrières solar farm illustrates how land can be repurposed to support the energy transition.
RWE has officially inaugurated its Pierrières solar farm, located in the municipality of Ardillières in Charente-Maritime, France. Launched in 2019 in collaboration with the local council, the project received its construction permit in 2023 and was selected the same year under the technology-neutral call for tenders issued by the French Energy Regulatory Commission (CRE). Construction began at the end of 2024, with electricity generation to start in the summer of 2025.
Spread across four plots covering a total of 3.6 hectares, the solar farm comprises 7,420 panels with a combined installed capacity of 3.37 MWac. It will generate enough green electricity to meet the annual needs of around 1,500 households, including heating.
The Pierrières solar farm will also deliver significant local economic benefits, as it is built on municipal land that provides an annual lease payment in addition to the usual tax revenues.
Katja Wünschel, CEO RWE Renewables Europe & Australia: 'With the inauguration of the Pierrières solar farm, RWE is taking another step forward in its solar activities in France, where we have strong ambitions. Delivered in less than five years – from development through completion of construction and commissioning - , this project demonstrates our operational capabilities and the excellent collaboration with local stakeholders that has been established throughout its development.'
Olivier Denéchaud, Mayor of Ardillières: 'The Pierrières solar farm brings multiple benefits: built on a former municipal landfill, it will generate substantial economic returns for our community and its residents. It also enables us to launch new projects, such as the renovation of municipal buildings — particularly our school.'
A project combining power generation and environmental excellence
This formerly unused municipal land is now being put to value through a solar farm that produces low-carbon electricity. RWE worked with leading experts to minimise the project’s impact on its surroundings by avoiding both dry and wet habitats characteristic of the area. Several measures have been implemented as a result, including the planting of hedgerows, the creation of wildlife crossings, and enhanced landscape integration through a limited panel height.
