Promoting biodiversity
Fourteen projects at a total cost of twenty-two million Swiss francs have been, or will soon be, completed to offset the environmental impact of the following constructions: pumped storage power plant and very high-voltage line connecting the power plant to the power grid.
Most measures aim to recreate specific biotopes locally, especially wetlands, in order to encourage recolonisation of the area by certain rare or endangered animal and plant species in Switzerland.
In the Rhone valley, a set of six measures aims to recreate corridors favourable to the movement of fauna between the mountain slopes and the Rhone, as well as wetlands which are home to a rich biodiversity of plants and animals.

Clos du Rhône
From the mouth of the Trient to the Dorénaz bridge, the bed of the Rhône will be widened to give it more room to expand, particularly in the event of flooding. Considered a priority, this measure is being carried out during the 3rd Rhône correction with the financial participation of Nant de Drance SA.
