Iberdrola has secured approval for its 315MW Windanker offshore wind farm from the German Federal Maritime and Hydrographic Agency (BSH).
The approval is a major step forward in the project, with the company now preparing to begin construction in the Baltic Sea offshore Germany.

The fabrication of 21 foundation structures, including monopiles and transition pieces, is proceeding on schedule.
Spanish firm Windar is in charge of production, and the timeline remains on track.
The installation of the foundations at sea will begin in the summer of 2025, with work on the internal cabling later in the year.
The Windanker project will be equipped with 21 Siemens Gamesa SG 14-236 DD turbines, each with 15MW generating capacity.
Clean energy generated by the wind farm will be sufficient to power 315,000 households in the region.
The overall investment required for Windanker totals €1bn ($1.07bn), and full operations are expected to begin in 2026.
Kansai, a Japanese energy corporation, holds a 49% stake in Windanker, having joined the project in December 2024, while Iberdrola retains a majority 51% share.
Power purchase agreements (PPAs) for the energy produced by the wind facility have already been secured by Iberdrola.
The project is an integral part of the company’s strategic expansion in the German energy sector. It represents the third major offshore wind initiative Iberdrola is undertaking in the country.
Iberdrola also oversees the nearby Wikinger and Baltic Eagle wind farms, with capacities of 350MW and 476MW respectively. These ventures will collectively form Iberdrola’s Baltic Hub.
By 2026, the Baltic Hub will reach a combined power capacity exceeding 1.1GW, and the total investments across these three projects will amount to €3.7bn.
Iberdrola Germany CEO Felipe Montero stated: “With the approval of the BSH, we have come a big step closer to realising our Baltic Hub in the German Baltic Sea.
“In total, our three wind farms will have a total capacity of 1.1GW. We are continuing our growth course and clearly demonstrating Iberdrola’s commitment to the German renewable energy market.”
In March 2025, Iberdrola signed a 1,000 gigawatt hours PPA with Italian retail company Pam Panorama.
