Hydro power is EDF Energies Nouvelles' original area of expertise.
It now operates hydro power plants with combined capacity totalling 128.4 MW in France and Bulgaria.

Micro hydro facilities are already very widely used, and the technology is now stable in EDF EN's target countries.
The development of combined hydro/wind power plants offers a promising way of generating electricity on islands.
EDF Energies Nouvelles is carrying out research with a view to initiating a project of this type in Greece.
