Iberdrola has completed the delivery of the final monopiles manufactured for its Windanker offshore wind farm , located in German waters of the Baltic Sea. These structures, essential for the foundation of offshore turbines, were produced by the alliance between Navantia SeaEnergies and Windar Renovables at their facilities in Fene (A Coruña), thus consolidating a long-term strategic relationship between the companies.
The development of this project represents a considerable boost for local and national industry. The production of the monopiles has generated around 300 jobs and is part of a framework agreement signed in 2021 for the supply of large foundations, known as XXL monopiles, which are increasingly in demand in the fixed offshore wind energy sector.
Advanced manufacturing and technological commitment at Fene

At Navantia Seanergies' facilities in Fene, the Navantia and Windar teams have worked together to complete this batch of foundations. Each monopile reaches up to 84 meters in length, 10 meters in diameter, and can weigh up to 2.100 tons —dimensions that reflect the scale of the infrastructure required for this type of deep-water wind farm.
To enable the manufacture of these parts, €36 million was invested in renovating the plant . The work included everything from adapting buildings for bending thick, large-diameter sheet metal to adding new paint booths and storage areas. State-of-the-art technological equipment has also been implemented to guarantee the quality and efficiency of the production process.
The decision to increase the plant's capacity has positioned Navantia and Windar as European leaders in the manufacture of foundations for offshore wind power, consolidating the competitiveness of the Spanish industry in this field.
Windanker Park and Iberdrola's Baltic Hub
Windanker is part of the ambitious offshore wind hub that Iberdrola is developing in the Baltic Sea , alongside the Wikinger (350 MW) and Baltic Eagle (476 MW) wind farms. Together, this energy complex will exceed 1.100 megawatts (MW) of installed capacity and represents a total investment of €3.500 billion.
Windanker is scheduled to become operational in 2026 and will provide a generation capacity of 315 MW . The park will be equipped with state-of-the-art offshore wind turbines, each with a capacity of approximately 15 MW, allowing for maximum utilization of the wind resource in the area.
This progress strengthens Iberdrola's position as a key player in the European and global energy transition, committed to large-scale renewable solutions and the use of advanced technology in the production and exploitation of wind energy in offshore environments.
Collaboration and industrial impact

The collaboration between Iberdrola, Navantia Seaenergies, and Windar Renovables has now spanned a decade of joint projects. During this period, the total value of orders exceeds €1.000 billion , with projects in key markets such as the United Kingdom, France, Germany, and the United States. This mutual trust has enabled them to tackle complex developments and position the Spanish companies at the forefront of international offshore wind energy.
The companies involved emphasize the importance of this strategic alliance. Both the presidents of Navantia and Windar Renovables emphasized the added value of contributing to both the strengthening of the national supply chain and the international recognition of their technological and manufacturing capabilities.
For Iberdrola, its long-term relationships with suppliers and the promotion of stable agreements allow it to maintain industrial activity in Spain and generate employment opportunities and ongoing technological development in the renewable energy sector.
Impact on the sector and new horizons

The experience gained from executing projects such as Windanker and East Anglia Three—the other major contract underway between Navantia, Windar, and Iberdrola in the United Kingdom—positions these companies as leaders in the construction of highly complex offshore foundations. In parallel, progress is being made in the manufacture of monopiles and other structures for new developments, in view of a future where offshore wind power is emerging as one of the key drivers of economic decarbonization.
Iberdrola's commitment to innovation and internationalization is reflected in projects that not only generate clean energy but also boost the business and technology landscape, especially in regions like Galicia, where monopile production has become a pillar of heavy industry.
