Here is list of 10 largest Offshore Wind power plant in the world, their capacity and some additional information.

1. Hornsea 1 Offshore Wind Farm (UK)

Located off the coast of Yorkshire, England, Hornsea 1 is currently the world's largest offshore Wind Farm. It has a total capacity of 1.2 gigawatts (GW) and comprises 174 wind turbines. Completed in 2020, it can generate enough clean energy to power over one million homes.

2. Gansu Wind Farm (China)

Situated in the Gansu Province, this offshore wind farm has a planned capacity of 6.7 GW, which will make it the largest offshore wind project in the world once completed. The project is part of China's ambitious plan to increase renewable energy generation and reduce carbon emissions.

3. Dogger Bank Wind Farm (UK)

The Dogger Bank Wind Farm, located in the North Sea off the east coast of England, will have a total capacity of 3.6 GW. It is being developed in three phases: Dogger Bank A, B, and C. Once fully operational, it will become the largest offshore wind farm in the world.

4. Greater Changhua Offshore Wind Farm (Taiwan)

The Greater Changhua Offshore Wind Farm, developed by Ørsted, is expected to have a total capacity of 2.4 GW. It is being constructed in two phases, with Changhua 1 and Changhua 2 projects. The wind farm will contribute significantly to Taiwan's renewable energy goals.

5. Hollandse Kust Zuid Offshore Wind Farm (Netherlands)

The Hollandse Kust Zuid Offshore Wind Farm is being developed in the Dutch North Sea. Once completed, it will have a total capacity of 1.5 GW. The project aims to provide clean energy to over one million households in the Netherlands.

6. Formosa 1 Offshore Wind Farm (Taiwan)

Situated off the coast of Miaoli County, Taiwan, Formosa 1 was the country's first commercial-scale offshore wind farm. It has a current capacity of 128 megawatts (MW) and consists of 22 wind turbines. The project is a collaboration between Ørsted, JERA, Macquarie Capital, and Swancor.

7. SeaMade Offshore Wind Farm (Belgium)

SeaMade is a combined offshore wind farm consisting of the Mermaid and Seastar projects. With a total capacity of 487 MW, it is the largest offshore wind farm in Belgium. Located in the Belgian North Sea, it can provide clean energy to approximately 485,000 households.

8. Borssele Wind Farm (Netherlands)

The Borssele Wind Farm, located in the Dutch North Sea, is a cluster of offshore wind projects. When fully operational, it will have a combined capacity of 1.5 GW. Borssele plays a crucial role in the Netherlands' transition to renewable energy and contributes to the country's goal of achieving a carbon-neutral economy by 2050.

9. Vineyard Wind (USA)

Situated off the coast of Massachusetts, Vineyard Wind is set to be the first large-scale offshore wind farm in the United States. With a planned capacity of 800 MW, it will provide clean energy to over 400,000 homes. The project will help the U.S. accelerate its renewable energy deployment and reduce greenhouse gas emissions.

10. East Anglia ONE Offshore Wind Farm (UK)

Located in the North Sea off the coast of Suffolk, England, East Anglia ONE has a capacity of 714 MW. It consists of 102 wind turbines and can generate enough renewable energy to power more than 630,000 homes. The project is a collaboration between ScottishPower Renewables and Macquarie's Green Investment Group.
