Offshore wind power is key to Iberdrola's future growth

Twenty years ago, the group was a pioneer in onshore wind generation, and now it is doing the same in the offshore wind market. During the last year, offshore wind power has become a major business growth vector for the company. At the end of the first half of 2021, the company already had more than 1.3 GW of installed capacity, which it will triple by building a further 2.6 GW by 2025. The enormous expansion of the company's pipeline of this technology will allow Iberdrola to have 12,000 MW in operation by 2030, with investments totalling almost 30 billion euros worldwide during the decade.

We are ready for the future with the biggest renewables pipeline in the industry

Within Iberdrola's renewables pipeline, which totals 81.5 GW, offshore wind has become the second-most-important technology thanks to strong growth in the last year. The company has invested in new growth platforms with enormous potential, such as Poland, Sweden, Ireland, Japan, Korea, Taiwan and Australia, which has made it possible to increase the size of our offshore wind stable to 25.2 GW. This ensures that we can fulfill our plant to 2030, when we will have 12,000 MW in operation.

Our major offshore wind projects

    East Anglia Hub
    Consisting of three wind farms, they add up to 3,100 MW and will be Iberdrola's largest offshore wind project.
    Kitty Hawk
    Off the Outer Banks coasts, they will have a capacity of 2,500 MW and will supply 700,000 households.
    Park City Wind
    With 804 MW, it will supply 14 % of the state of Connecticut's electricity needs.
    Vineyard Wind 1
    With 800 MW, it will be capable of meeting the energy needs of more than 400,000 homes.
    With the start of the operation phase in 2023, it will have a total installed capacity of 496 MW.
    Baltic Eagle
    This new 476 MW facility is our second flagship project in Baltic waters.

We are continuing to grow to establish ourselves as the world leader in offshore wind farms

As well as the wind farms in development, Iberdrola has an additional pipeline of 22.6 GW. This puts Iberdrola in an optimal position when participating in auctions and tenders planned for the coming months in its new growth platforms for both projects in its existing pipeline (United States, 3,600 MW; United Kingdom, 3,100 MW; Japan, around 2,000 MW; Germany, 300 MW) and for new pipeline (Poland, 14 GW of capacity up for auction; United Kingdom, 10 GW of capacity up for auction; United States, approximately 7 GW; Ireland, around 5 GW of national target 2022-2025; France, 1.6 GW; Denmark, 1.6 GW; the Netherlands, 1.4 GW; and Taiwan, 6 GW).

What are wind turbines and how do they work?

Have you ever wondered how a wind turbine tower can support so much weight? Or why they are all orientated in the same direction? It is curious to see how wind turbines appear to work in sync. It's like watching a football team, with all of the members placed strategically and turning in the same direction. It may seem coincidental, but it is not: every detail of their functioning is governed by carefully studied and defined reasons. Find out all about them!

Floating offshore wind power: a milestone for driving renewables through innovation

The wind's power is stronger over the ocean than on land, which is why offshore wind power has developed in recent years. Until recently, they could not be installed in very deep or complex seabed locations because they were based on fixed structures, something that has changed with the emergence of floating structures. Wind turbines can now be installed on floating platforms that are anchored to the seabed by means of flexible moorings, chains or steel cables.

How does an offshore wind farm work? 

Offshore wind energy is the clean and renewable energy obtained by taking advantage of the force of the wind that is produced on the high seas, where it reaches a higher and more constant speed than on land due to the absence of barriers. In order to make the most of this resource, mega-structures are installed that are seated on the seabed and equipped with the latest technical innovations. Discover what these real sea giants are like and how they work.
