The Wind Farm has capacity to fully meet El Hierro´s demand for electricity. The surplus wind energy which is not consumed by the Island´s population is used to pump water from a lower reservoir to a higher reservoir. This water is stored in the upper reservoir and used to produce electricity by means of a hidraulic jump at times when the wind power is inadequate.
The combination of wind- and hydro- power succesfully transforms an intermittente energy source – wind- into a continuos, controlled supply, and represents an innovative contribution to the advancement of the renewable energy sector.
The diesel-engine-powered Power Station only comes into operation in exceptional circumnstances when theres is not sufficient wind or water to produce enough energy meet demand.
