Offshore wind power

Leaders in wind generation, also in the sea

Offshore wind power, key to Iberdrola's future growth and its commitment to the energy transition.

Twenty years ago, the Group was a pioneer in onshore wind generation, and now it is doing the same in the offshore wind power market, one of the company's major growth vectors. At the end of 2022, we have 1,258 MW offshore in operation and 5,500 MW under construction or secured with long-term contracts, which will come into operation before 2027 thanks to investments of around 30,000 million euros worldwide during this decade. 

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

Within Iberdrola's renewables portfolio, which totals 90 GW, offshore wind energy is the second most important technology, thanks to the strong growth experienced in the last year. The company has committed to new growth platforms with great potential, such as Poland, Sweden, Ireland, the United States, Brazil and Japan, which has allowed our offshore wind portfolio to now exceed 30 GW. In this way, we have ensured compliance with the plan to 2025, when we will reach 3,100 MW in operation.

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

The significant expansion of the offshore wind pipeline 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 Kingdom, 3,100 MW; United States, 1,200 MW; Japan, 1,800 MW) and for new pipeline (Poland, 5 GW of capacity up for auction; United Kingdom, 10 GW of capacity up for auction; United States, 37 GW; Ireland, around 5 GW of national target 2022-2025; France, 1.6 GW; Denmark, 1 GW; the Netherlands, 1.4 GW; South Corea, 12 GW; Vietnam, 2 GW; and Taiwan, 9 GW).

Everything you'd like to know about offshore wind farm construction

The harnessing of offshore wind energy requires the installation of impressive offshore wind farms with large wind turbines equipped with the latest technology. The design, construction, transport and installation of such mega-structures offshore is a technical challenge, highly refined with experience, and requires a process lasting several years.

How an offshore wind farm is built

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.
