  • Our hydropower generation assets in Spain

    We have 12 hydropower plants in northern Spain with enough annual output capacity to supply every single household in the city of Madrid.

    Along with our other renewable energy generation projects, this will help us become a net zero emissions company by 2050.

  • How does a hydropower plant work?

    These facilities make it possible to take advantage of the energy in the water in a river or reservoir to turn it into electric energy.

In case you still have any questions...

  • Water falling in a hydropower plant

    How does it work?

    Flowing water from a river or a dam falls on the blades of a turbine, making a generator spin to produce electricity. The power generated is fed into the distribution network which is then delivered to homes, businesses, etc.

    Is it eco-friendly?

    Yes, this is a zero emissions electricity generation process. Also, all the water that's used in the process is returned to the river or dam in its original state with its quality intact.

    How much energy is produced like this?

    In 2019, 9% of the total energy produced in Spain was generated in hydropower plants. This production is part of Spain's renewable energy mix, which has been on the rise for years now.
A Certificate Maximum Grade Level: 100% Renewable Electricity

Guaranteeing with the highest certification the 100% renewable origin of the electricity we offer

The Spanish National Commission on Markets and Competition (CNMC) awarded us the highest certification – the A label – for the environmentally friendly origin of the electricity we offer. This makes us the only major retailer, in terms of customers supplied, to be awarded this label for the second year in a row. Also, we provided 100% renewable energy in 2020.
