EDF - Le Bazacle site Toulouse (31) & 
Golfech site (82)

EDF, the leading producer and supplier of electricity in France invites you to discover electricity and nuclear power. How do we produce electricity? How does a nuclear power plant work?

Come and get the answers directly on site!



The history of the Bazacle is rich and of great importance for the city of Toulouse. This place combines history, industrial heritage and environment.

It is a run-of-river plant, meaning that it produces 24 hours a day, 7 days a week for an installed power of 3 Megawatts. This corresponds to the electricity consumption of 12,000 people! Today, it supplies the EDF network. Hydroelectricity, a renewable energy, represents on average 10% of the electricity production of the French energy mix. By participating in the guided tour, you will have the chance to enter the engine room and discover the century-old alternators still in operation!

From the Bazacle terrace, you will enjoy an exceptional view of the tumultuous Garonne, Toulouse's heritage, in particular the dome of La Grave and the Pont Neuf, but also of the fish pass! The fish pass is the particularity of the site. Born in the Pyrenees, the salmon travels between fresh water and salt water and begins a journey to return to reproduce in the river where it was born: the Garonne.

Arrived at Golfech, nuclear and hydraulic power station, it takes the fish lift to cross the dam 17 meters high. He continues to go up the Garonne and arrives in Toulouse, the fall of 4 meters in height of the Bazacle preventing him from crossing, our salmon then takes the fish pass. These are several successive basins allowing him to cross the fall, a bit like a staircase! Once in the Pyrenees, the salmon give birth to the next generation which will make the same journey as its parents.

As you will have understood, via the fish passes EDF is committed to promoting the ecological continuity of the Garonne. Follow us now in the Gallery of the eye of the Bazacle, this gallery dates from 1814. At the time, it was used to conduct water to the old turbines, today you can enjoy photo exhibitions. But above all you are now under the Garonne and you can observe the porthole of the fish pass. You may be lucky enough to observe fish! The salmon migration season runs from April to June.
