Saint-Etienne (Loire) has for some time undertaken an energy transition process by investing heavily in solar energy. The city has invested in the installation of solar panels on the roofs of 150 buildings by 2021. Several buildings will thus be able to be supplied with electricity: the Geoffroy-Guichard stadium, the Museum of modern art, the Opera or even school and sports buildings ... In town, nearly 200,000 square meters of surfaces will be covered.
These 20 ha of solar panels will then enable Saint-Etienne Métropole to produce 33 gigawatt hours per year of electricity, ie the electricity consumption (excluding heating) of 12,000 homes. This approach by the city will thus prevent the release of 15,000 tonnes of CO2 into the atmosphere.
The Saint-Etienne trams will also be powered by solar energy. In fact, 5,000 photovoltaic panels are being installed on the roof of the Stas depot (Société des transports de l'Agglomération Stéphanoise) and will thus enable part of the Saint-Etienne tram network to be supplied.
The investment is carried by GreenYellow (a subsidiary of the Casino Group) and its subsidiary Reservoir Sun.

Sustainable Development
Testimony / Feedback
“This ambitious heritage solarization project is part of the sustainable development policy pursued by SaintEtienne Métropole since 2014 and represents a major development in terms of energy transition. Through this project, unprecedented in France, our metropolis is once again demonstrating its ability to evolve, innovate and transform ”declared Gaël Perdriau, Mayor of Saint-Etienne and President of Saint-Etienne Métropole.
"Faithful to the requirements and expertise of our group, TRANSDEV - the leading European operator of zero emission mobility - STAS is proud to carry out this solarization project and to act in favor of the" Positive energy territory "policy led by Saint-Etienne Métropole ”specifies Ludovic Jourdain, Director of Stas.
“I am very proud to support Saint Etienne Métropole in this major project. For GreenYellow, this is the demonstration of our ability to be a real partner for communities and public authorities in their energy transition, with solarization of course but also energy efficiency. Saint-Etienne is a very special city for GreenYellow, cradle of the Casino group, and we are happy to continue this historic link by committing ourselves to its side ”, declared Otmane Hajji, President of GreenYellow.

Private
Local authorities provide areas for installing photovoltaic panels. From this provision of these areas, these same communities receive a rent.
Also, self-consumption infrastructures will be able to benefit from green energy at lower costs.
Finally, this allows them to be able to become shareholders, if they so wish, of the holding companies which will operate these photovoltaic plants and thus receive dividends.
GreenYellow and Reservoir Sun will lease these areas and then install, finance and operate these plants. This will allow them to derive a turnover from it by reselling the electricity produced.

Saint-Etienne trams powered by solar energy
The Saint-Etienne trams will also be powered by solar energy. In fact, 5,000 photovoltaic panels are being installed on the roof of the Stas depot (Société des transports de l'Agglomération Stéphanoise) and will thus enable part of the Saint-Etienne tram network to be supplied. The photovoltaic plant on the Stas site will inject directly into the supply network of the trams.

Les points forts de la démarche :
- Transition énergétique de Saint-Etienne Métropole (Loire) via l'installation de panneaux solaires sur les toits de 150 bâtiments d'ici à 2021. En ville, ce sont près de 200 000 mètres carrés de surface qui seront couverts.
Ces 20 ha de panneaux solaires vont ainsi permettre à Saint-Etienne Métropole la production de 33 gigawatts/heure par an d'électricité, soit la consommation électrique (hors chauffage) de 12 000 logements. Cela permettra ainsi d'éviter le rejet de 15 000 tonnes de CO2 dans l’atmosphère.
- L'alimentation en énergie solaire d'une partie du réseau de tramways de Saint-Etienne via l'installation de panneaux photovoltaïques sur la toiture du dépôt de la Stas (Société des transports de l'agglomération stéphanoise)
