Gorona del Viento El Hierro, S.A., is the company responsible for the running, operation and maintenance of the “Wind-Pumped Hydro Power Station”. The purpose of the facility is to supply El Hierro, the Meridian Island, with electrical energy derived from clean, renewable sources such as water and wind.

A wind farm produces energy which is directed into the Island’s electricity grid to satisfy the population’s demand for electricity. The surplus energy that is not consumed directly by the Island’s inhabitants is used to pump water between two reservoirs set at different altitudes. During times of wind shortage, the water stored in the Upper Reservoir is discharged into the Lower Reservoir, where the Wind-Pumped Hydro Power Station is, to generate electricity from its turbines.

In this way, an intermittent, fluctuating source of energy can be converted into a controlled, constant electricity supply, guaranteeing that the grid remains stable and optimising the benefits of renewable energy sources. The diesel-engine-powered Power Station only comes into operation in exceptional circumstances when there is neither sufficient wind or water to produce the energy to meet demand.

World-class innovation

A benchmark in the development of renewable energy and environmental respect.

This ground-breaking system, which is unique in the world, has transformed El Hierro into a flagship for the development of renewable energies and for respect for the environment thanks to the high percentage of electricity which it succeeds in generating from clean sources, resulting in a saving on diesel and a considerable reduction in CO2 emissions.

El Hierro’s Island Council maintains a 65.82% holding in Gorona del Viento, while Endesa holds 23.21%, the Instituto Tecnológico de Canarias (Technological Institute of the Canary Islands) holds 7.74% and the Canary Islands Government 3.23%.


Gorona del Viento is committed to transparency, innovation and sustainability as fundamental values. That is why it annually allocates resources to activities that generate a positive impact on the society of Herrera.
