Our wind energy projects

Our three onshore wind energy projects are located in the Spanish regions of Aragon and Castile-Leon.


Production capacity: 335 MW 

Location: Between the provinces of Zaragoza and Teruel  

Characteristics: Features 89 turbines

Delta 2 

Production capacity: 860 MW 

Location: Between the provinces of Huesca, Zaragoza, and Teruel 

Startup year: 2023 

Characteristics: Consists of 26 wind farms


Production capacity: 175 MW 

Location: Between the provinces of Palencia and Valladolid 

Startup year: TBD

Did you know...? Thanks to our Delta 2 project, it'll be possible to supply energy to 1.8 million people, which is more than the entire population of the Spanish region of Aragon.

  • How does wind energy work

    Wind turbines take full advantage of wind energy to turn it into electricity.

Discover step by step how wind energy works

A renewable, clean source of energy that harnesses the strength of the wind to generate electricity.
  • Illustration of wind turbines


    The blowing wind spins the blades of the turbine and activate a generator. Turbines have a vane that indicates the direction of the wind and automatically orient them to take full advantage of the energy.
  • Illustration of the parts of a wind turbine


    The turbines also a gearbox that increases the rotational speed of the shaft to thousands of revolutions per minute. The resulting kinetic energy is then transferred to the generator which, through magnetic fields, converts it into electric energy.
  • Illustration of a power substation


    Finally, the electricity is sent to a converter in the base that transforms it into alternating current, which is then sent to a booster substation. From the booster substation, the energy is then transported to the grid for consumption.
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.

Committed to the fight against climate change

WindFloat is another one of our renewable energy, environmentally-friendly projects that contributes to our commitment to becoming a net zero emissions company by 2050.
