Competitive and abundant, photovoltaics is one of the sectors where the price drop has been the most dramatic.

Technical progress has reduced the cost of equipment and installations. The massification of installations has made it possible to increase competence and optimize production and construction processes.

Wind power is a competitive means of producing electricity and has many advantages: its resource, the wind, is inexhaustible. A wind turbine produces electricity without emitting greenhouse gases, yet the installations are completely reversible: at the end of operation, a site returns to its original appearance.


Beyond its contribution to the development of renewable energies, biomass involves local players and therefore stimulates a territorial dynamic. For the territories where the subsidiary is developed, it presents many interests: energy, economic and, of course, environmental.



Hydro Power in many countries remains the most competitive source of non-intermittent energy. Coupled with storage it can enable the integration of even cheaper sources of intermittent energy.

Well-designed Hydro Power Project provides low level of CO2 emissions, high energy efficiency and load factor, making this source of energy both competitive and reliable.


Voltalia is developing a new sector in its project portfolio: storage, which enables energy production to be optimised. Storage allows us to ensure continuity of supply in the event of a problem on the network, and more generally to improve the quality of service and integrate more intermittent renewable energies.
