El Hierro island: supplied in a 100% by renewable sources


On 9/08/2015, Gorona del Viento hydro-wind power plant supplies with energy from clean sources to all the residents of El Hierro island.

Technically, the plant consists of a wind farm of 5 grid-connected wind turbines and an hydroelectric power station with 4 generators made by ALCONZA, capable of producing 35 GW/h of energy to supply the population. These generators (2,825MVA/unit) perform when the windmills do not produce enough energy and due to this the waterfall must be exploited.

The project is a world leader not only by the technological achievement record combining different natural energy sources, but also because it is the first time a project of such magnitude and dimensions has ever built.

For the next decade, it is expected that the implemented system will generate a saving of 80 million of Euros due to 6.000 tons per year of less burned diesel and 20.000 tons of CO2 less poured to the atmosphere.
