The "run-of-river" hydroelectric power stations represent in France, in 2012, 30% of the power of the hydroelectric power plant (with more than 2,000 power stations) with a total power of 8,500 MW and producing an energy of 32 TWh .
Or 52% of French production. The bigest power plants are over the Rhône and the Rhine.

Run-of-river production consumes neither water r fossil fuels, it uses a renewable and inexhaustible source of primary energy (the current)
Run-of-river power plants do not emit CO₂, pollutants or waste.

"Run -of-river" hydroelectricity refers to the production of electricity by a hydroelectric power station that operates without water, so that it can not be stored during periods of high flow detocking during low water periods.

# data[].attributes.body
The electrical energy is produced by the transformation of kinetic energy of the water into electrical energy by means of a hydraulic turbine couplet to an electric generator

# data[].attributes.body
Run-of-river power plants dont have the capacity to modulate their production acording to the needs of the consumers or the operator of the network

# data[].attributes.body
On the contrary their production varies greatly acording to climatic events (rains droughts seasons etc ...) Like wind turbines and solar power, they form parts of renewable energy.

# data[].attributes.body
Running hydroelectricity is safe, clean, inexpensive source of energy that is close to consumers, Supports the distribution network, while limiting online losses.
It contributes to the development of renewable energy
