Hydroelectric energy
Hydroelectricity is the second largest source of electricity production after nuclear energy and the primary source of renewable electricity in France. Flexible and storable, it contributes actively to the balance of the electricity system and to network safety.
Primary source of renewable energy in France
Hydroelectric energy is the primary source of renewable energy in France. With 20 GW of installed capacity and more than 10% of its electricity supplied by hydroelectricity, EDF is the leader in hydropower energy in the European Union.
Available on demand
Hydroelectric energy can be switched on in a few minutes and at any time. It responds to sudden fluctuations in electricity demand at a low cost thanks to the water stored in EDF dams. Such flexibility makes it the ideal adjustment lever for EDF in the face of sudden variations in consumption.
Supporting local challenges
Local economy and dialogue
EDF's hydroelectric energy business is a great asset for the economic development of the regions. The lakes formed by dams give rise to activities that are important for the tourism industry. EDF launched the ‘One River, One Region’ programme to support growth and innovation in hydroelectric valleys.
Water use based on consultation
Dams operated by EDF in mainland France have a capacity of around 6 billion m³ of water. The Group works with local stakeholders to ensure that this resource is shared and used correctly. It is also involved in its long-term preservation and anticipates the effects of global warming.
Protecting biodiversity
EDF gives great importance to ensuring compatibility between biodiversity and hydroelectricity and, more generally, preserving fauna and flora close to production facilities.
