ENGIE has gained national and international recognition in the development and responsible operation of hydroelectric plants.
Hydroelectric power plants generate electricity using the kinetic and potential energy of water. The water drives turbines that in turn drive generators which convert mechanical energy into electricity.
ENGIE operates three main categories of hydroelectric power plants:
Countries with rich hydroelectric resources are the first to meet their electricity needs with renewable electricity production.
Hydropower promotes the growth of intermittent renewable energies such as wind and solar, thanks to its flexibility in terms of dispatching* and storage, meeting demand when these variable sources are not available and allowing energy storage when there is a surplus.
Hydroelectric power plants are flexible and reliable and they have a long service life.
* Management of energy distribution on power grids to keep supply and demand in balance
Greenhouse gas emissions from hydroelectricity are mainly due to the use of cement (depending on the type of cement and its production method) and, in the form of methane, during the first years of filling reservoirs in tropical areas. These emissions are negligible.
Hydroelectric power is the second largest source of electricity production in France. ENGIE, the second largest national producer, produces 25% of the country's hydropower, contributing to the promotion of this type of renewable energy working in conjunction with local authorities and regional businesses and participating in regional development benefiting the population, in conjunction with local authorities and regional businesses, through its two subsidiaries, Compagnie Nationale du Rhône (CNR) and La Société Hydro Electrique du Midi (SHEM).
ENGIE, together with its consortium partners Crédit Agricole Assurances and Mirova, an affiliate of Natixis Investment Managers, have acquired the second largest hydroelectric portfolio of Portugal, with a generation capacity of 1.7 GW a concession term of 45 years. This hydroelectric portfolio includes three newly commissioned pump storage units along with three recently repowered run-of-river plants. ENGIE, as the industrial partner for the consortium, will operate and maintain the hydroelectric portfolio and also provide energy management services.
ENGIE is the country's leading independent producer of electricity, operating 61 plants, including 12 hydroelectric plants. These major projects are backed up by initiatives and projects carried out in close collaboration with local associations and structures.
ENGIE Energía Perú operates two hydroelectric plants: Yuncán (with a nominal capacity of 136.5 MW) and Quitaracsa (with a total nominal capacity of 118 MW).
ENGIE operates 3 hydroelectric power plants: Tanzmühle, Reisach and Trausnitz.
ENGIE led the construction of the Laja hydroelectric plant, the first run-of-the-river power plant in Chile, on the lower section of the Laja River. A system of turbines installed at the foot of the dam avoids the need to divert the river and minimizes the dam’s environmental impact. This project is one-of-a-kind in Chile.
The Europe Generation BU operates the Coo-Trois-Ponts pumped storage power station, a facility with an installed capacity of 1,164 MW located in the Ardennes, near the Coo Waterfall.
First Hydro Company, a subsidiary of ENGIE, is one of the most successful electricity generators in the UK with an installed capacity of 2,088 MW. It manages and operates the Dinorwig and Festiniog pumped storage power stations, located in the Snowdonia region of Wales.
