Renewable energy in Spain: how tides and waves can be used to produce clean energy.
Although Spain has almost 6,000 kilometers of coastline, there are currently no tidal energy plants, but there have been projects to produce wave energy in the Basque Country, Cantabria and Galicia.
The only one of these that currently survives is the Mutriku plant, in Guipúzcoa (Basque Country). Although many believe it to be a tidal power plant, this plant only produces clean energy from ocean waves, not from changes in tides.
The Mutriku project, promoted by the Basque Energy Agency, has been the first wave production center in Europe, since its installation in 2011. It has 16 turbines that produce about 600,000 kWh of electricity annually and supplies about 600 homes. with electricity.
It is clear that the exploitation of tidal and wave power from the sea has not yet reached its peak and that its development does not compare with the rapid expansion that solar and wind power have seen in recent years. This could change as Spain has huge potential for tidal power generation in the Strait of Gibraltar and a plant there could replace the country’s nuclear power production entirely, explains Magallanes Renovables’ managing director Mario Iglesias Casals. The Galician company has already been producing tidal energy since 2 March this year, but it does so on the ATIR platform in Scotland’s Orkney Islands. This platform has a submerged mast with two blade turbines. As it is a floating platform, it avoids the installation of pillars that have a negative impact on the environment.
