An island with 100% renewable energy
With 276 km² and more than 10000 inhabitants, El Hierro is the smallest island of the Canary archipelago ( Spain ). The island has its own electricity grid; it is totally isolated as the significant sea depths make any interconnection impossible. Till a little time ago , the electricity demand, which accounts for about 65% of the internal energy consumption, was mainly covered by a conventional thermal power station (10MW diesel-fired system). The contribution of renewable energies to the electricity grid was
less than 5% and came from two wind turbines installed close to the main town (100 kW and 180 kW).
El Hierro, the smallest island of the Canaries, is staging one of the most ambitious island projects regarding energy self-sufficiency through the use of renewable energies. In a few years, El Hierro will become one of the first islands in the world to meet its energy demand using RES (Renewable Energy Sources). Considered as one of the most audacious actions of the strategy established in the European Commission White Paper on Renewable Energies, the project is already a reference for other islands, such as Crete and Madeira…
