Vitrolles: One of France’s Largest Solar Energy Communities in 2026

In Vitrolles, in the Bouches-du-Rhône department, an unprecedented chapter of France's energy transition is being written. The city has awarded a concession contract for the rollout of Notre Énergie Vitrolles, one of the largest local energy communities in France, led by the companies SerenySun and Watteos. A first loop, known as the “North loop,” has already been operating since spring 2026, and the project's official inauguration is scheduled for October 2, 2026.

The principle is that of collective self-consumption: electricity produced locally from solar panels installed on municipal buildings is shared in a short circuit among several nearby parties, rather than being fed indiscriminately into the national grid. In practice, a school, a satellite town hall, or a gymnasium equipped with photovoltaic panels can directly supply neighboring homes or businesses.

A Project of Unprecedented Scale in France

The financial and technical structure of Notre Énergie Vitrolles stands out for its scale: roughly 10 million euros in investment, 25 municipal sites equipped with solar panels covering some 25,000 square meters of rooftops, for an expected annual output of around 8 GWh of renewable electricity. Ultimately, the project aims to cover nearly 29% of the city's electricity needs.

• Total investment: approximately 10 million euros
• 25 municipal buildings equipped, covering nearly 25,000 square meters of panels
• Target output: approximately 8 GWh of renewable electricity per year
• Goal: covering up to 29% of the city's electricity consumption

The project's legal structure is distinctive: according to several specialized media outlets, it would be the first energy community in France set up as a long-term concession contract, rather than a standard collective self-consumption agreement. This arrangement commits the local government and its private partners for several years, with precise specifications governing production, maintenance, and the distribution of the electricity generated.

Public Buildings, Businesses, and Residents on the Same Network

The network brings together three types of participants: public buildings (schools, sports facilities, municipal offices), local businesses based in Vitrolles, and volunteer residents, who become both producers and consumers of the electricity generated. This model, still rare at this scale in France, is part of the broader momentum behind positive energy projects led by local governments.

For local businesses, taking part in this kind of network can help control energy costs, at a time when electricity prices remain a concern for many local businesses and industries. For individual residents, the issue ties into broader questions related to housing and energy renovation, a topic closely followed by households working on improvements to their home.

A Gradual Rollout Leading Up to the Inauguration

The system is being rolled out in stages: after the North loop went live in spring 2026, other parts of the city are expected to gradually join the network before the project is officially presented to residents on October 2, 2026. The project's backers describe this phase as a “pioneering” step for the local energy transition, one that could inspire other French towns pursuing similar large-scale collective self-consumption initiatives.

Frequently Asked Questions

What is a local energy community?

It is a system that allows several geographically close parties (local government, businesses, residents) to jointly produce and consume renewable electricity generated locally, in a short circuit, rather than relying solely on the national power grid.

How can Vitrolles residents take part in the project?

Willing nearby residents can join the network as consumers, and in some cases as producers, of the electricity generated by the panels installed on municipal buildings, according to the terms set up by the project's operators and the city.

Which buildings are involved in the solar panel installation?

The project covers 25 municipal sites (including schools, sports facilities, and administrative buildings), representing about 25,000 square meters of rooftops fitted with photovoltaic panels.
