The island of El Hierro broke the world record in isolated territories thanks to the Gorona del Viento hydroelectric power station, a plant that has already avoided emitting 80,000 tonnes of CO2 into the atmosphere.

Last year, it had already reached a record figure: consuming 100% renewable electricity produced on the island for 18 consecutive days (from January 25 to February 12, 2018), according to data from Red Eléctrica de España.

New registration.

El Hierro breaks the world record for renewable energies in isolated territories with 24 consecutive days of consecutive generation exclusively from the Gorona del Viento hydroelectric power station.

Between July 13 and August 7, all electrical energy consumed at El Hierro came from clean sources (wind turbines and hydro), and there are already more than 4,800 hours since the first 100% renewable period that took place on August 9, 2015. Hydroelectric power The plant has covered 52% of El Hierro’s electricity demand so far this year, a figure that is expected to continue to rise during the summer as the effect of the trade winds increases. It is estimated that since its commissioning, Gorona del Viento has prevented the emission of some 80,000 tonnes of CO2 into the atmosphere.

A world leader in generation innovation with renewable energies.

The president of Gorona del Viento and Cabildo de El Hierro, Alpidio Armas, stressed that this 24-day record is “one more step towards decarbonisation and the complete supply of renewable energies“. Armas took the opportunity to recall that Gorona del Viento completed its first five years of operation last June and”Since then it has been a fundamental piece for the integration of renewable energy production into the power system of this island and an example for other isolated systems“.

El Hierro has become the world capital of generation innovation with renewable energies. The succession of coverage records marks a path for a sustainable future based on an energy model of self-sufficiency with alternative energies, the experience accumulated in the management of the hydropower plant is an opportunity to forge links with other regions that are moving towards self-sufficiency. -sufficiency ”, while affirming that being the first isolated territory in the world capable of using water and wind as the majority source of electricity production makes it“ a technological example, but also a tourist attraction and a reference for training of experts in innovation with renewable energies.

The Gorona del Viento system is designed to supply Meridian Island with electricity from clean, renewable sources such as water and wind.

The wind farm is able to meet the electricity demand of the whole island. The wind surplus not used by the population is used to pump water between the lower and upper reservoirs; the water which remains accumulated in the latter reservoir and will be responsible for the production of electricity from the hydraulic jump in periods of low wind.

The plant was commissioned on an experimental basis in June 2014, an idea born over 20 years ago, when Endesa opened an alternative energy department in the Canary Islands. With a guarantee of over 300 windy days per year and large natural cavities that served for large water reservoirs, the waterfalls for periods of calm wind maintain energy production.

The wind surplus not used by the population is used to pump water between the lower and upper reservoirs; the water which remains accumulated in the latter reservoir and will be responsible for the production of electricity from the hydraulic jump in periods of low wind.

The diesel engine plant is only put into operation in exceptional cases when there is neither wind nor enough water to produce the necessary energy.
