A family-run quarry extracting a distinctive white limestone with golden reflections in Bouches-du-Rhône has had the main hangar roof renovated with support from French energy company Tenergie. The industrial building, integral to the site’s operations, required complete refurbishment to maintain safety and operational continuity.
A renovated structure with no upfront investment
Tenergie oversaw the full scope of the works, which included dismantling the old roofing, reinforcing the structural framework, and installing a new steel deck roof. A 270 kilowatt-peak (kWc) solar plant was then installed on the new surface and is now operational. The electricity generated is fed into the local public grid.
The project was implemented under a 25-year lease agreement, allowing the quarry operator to benefit from upgraded infrastructure without any initial capital expenditure. This model provides a renewed industrial roof while incorporating an energy production asset.
A replicable model for industrial sites
The plant produces electricity equivalent to the annual consumption of 152 people, according to data provided. Its operation is expected to offset approximately 80 tonnes of carbon dioxide (CO2) emissions per year.
This initiative is part of Tenergie’s deployment strategy, which supports industrial operators in upgrading existing structures with integrated photovoltaic solutions. The aim is to utilise already developed surfaces to increase decentralised electricity production without requiring additional land.
