- Capacity: 1,075 MW
- Turbines: 114 Vestas V164 10 MW
- Status: Operational since 2023
Scotland’s Seagreen 1 wind farm showcases European leadership in offshore wind energy. With a capacity of 1,075 MW, it highlights the significance of Vestas turbines in the renewable energy revolution. Seagreen is also the deepest fixed-bottom offshore wind farm.
6. Moray East
- Location: Scotland, North Sea
- Capacity: 950 MW
- Turbines: 100 Vestas V164 9.5 MW
- Status: Operational since 2022
Moray East wind farm is a major Scottish offshore cluster. It goes on to underscore the region’s commitment to sustainability. With a capacity of 950 MW, it features advanced Vestas V164 9.5 MW turbines.
7. Triton Knoll
- Location: United Kingdom, North Sea
- Capacity: 857 MW
- Turbines: 90 Vestas V164 9.5 MW
- Status: Operational since 2022
Developed by RWE, J-Power, and Kansai, Triton Knoll lights up the UK’s coastline with 857 MW of clean energy – another significant achievement in the region’s offshore wind power. Vestas turbines ensure the efficiency and reliability.
RWE is also developing the
8. Greater Changhua 1 & 2a
- Location: Taiwan, Taiwan Strait
- Capacity: 847 MW
- Turbines: 111 Siemens Gamesa 8 MW
- Status: Operational since 2022
Greater Changhua significantly contributes to Asia’s renewable energy capacity, boasting 847 MW generated by Siemens turbines. The wind farm is also the largest in Asia to date.
9. Borssele 1 & 2
- Location: Netherlands, North Sea
- Capacity: 752 MW
- Turbines: 94 Siemens Gamesa 8 MW
- Status: Operational since 2020
The Borssele 1 & 2 is a pioneer in offshore wind energy in the Dutch region. It stands as a testament to the Netherlands’ dedication to clean power generation. With 752 MW capacity and 94 Siemens Gamesa turbines, it has paved way for future offshore projects.
10. East Anglia ONE
- Location: United Kingdom, North Sea
- Capacity: 714 MW
- Turbines: 102 Siemens Gamesa 7 MW
- Status: Operational since 2020
This is the first of Iberdrola’s East Anglia projects. Operational since 2020, the East Anglia ONE continues to reassert the dominance of UK’s offshore wind.
Another East Anglia project in development is its third installment. The 1.4 GW power scheme recently a
Outlook on the top ten biggest offshore wind farms in the world
These top ten largest offshore wind farms in the world are pioneering a sustainable energy future. They continue to showcase the remarkable potential of offshore wind power and contribute significantly to reducing carbon emissions.
The projects also seem to be mainly from Europe and Asia, with unseen leads from the West. However, the U.S is also gearing up its offshore wind deployment with projects like the CVOW project despite resistance from President Donald Trump’s administration.
As 2025 progresses, these giants of clean energy continue to light the way toward a greener and more environmentally friendly world, reaffirming their positions as the largest wind farms globally.
