🔋🚗Electric mobility is gaining speed in Yvelines with SEY: over 300 charging stations installed!
Rédigé le 12 May 2025
As part of its commitment to deploy electric mobility across its 201 member municipalities, SEY 78 – Syndicat d’Energie des Yvelines, in partnership with Bouygues Energies & Services, an Equans France entity, is strengthening its Electric Vehicle Charging Infrastructure offer.
Objective? Make access easier for everyone by providing charging stations well located and close to where citizens live and work.
As part of this program, our teams—mobilized since 2019—contribute across the entire value chain:
- 304 charging stations already installed and 100 more planned for 2025, including 90 standard AC chargers and 10 ultra-fast DC chargers to meet different needs
- Maintenance contract for charging stations ongoing until 2027, ensuring network reliability
- 24/7 supervision and user services via the Alizé® solution
A big thank you to the SEY for their trust in this mobility decarbonization project and to our teams for their commitment.
