The most recent major hydropower investment project is designed to keep the
La Rance tidal power plant in Brittany operating at the highest efficiency level. The plant has been generating electricity from tidal energy for 50 years. The La
Rance Project is a 10-year EDF investment programme at the site, which includes:
- renovation of the 24 bulb turbines, the gates and the automatic control systems (gantry cranes, lifts)
- replacement of the extra high voltage (245 kV) outgoing transmission cables.
The objective is to ensure the long-term generation of clean, predictable and renewable power over coming decades. The La Rance tidal plant will continue to generate electricity while work is carried out.
