List of Top 7 Largest Upcoming Wind Farm Projects by Ørsted (according to capacity)

Hornsea 3

Hornsea 3 is set to become one of the largest offshore wind projects in the world ever built by Orsted, delivering clean electricity for more than three million UK homes. The 2.9 GW project covers 696 square kilometres in the Hornsea zone and uses up to 231 Siemens Gamesa 14 MW turbines.

Construction began in 2023, and completion is targeted for the end of 2027. Ørsted will manage the project from its operations hub in Grimsby and will also run the associated 300 MW battery storage facility at Swardeston.

Apollo Global Management agreed in November 2025 to acquire a 50 percent stake, while Ørsted will continue to lead construction under a full-scope EPC contract. The company will also handle long-term operations, maintenance, balancing services, and market access for the power the project produces.

Hornsea 3 sits 160 kilometres off the Yorkshire coast, close to the operational Hornsea 1 and 2 sites. Once Hornsea 3 comes online, the zone will exceed 5 GW of capacity, the largest operating offshore wind cluster in the world. Ørsted took the final investment decision (FID) on Hornsea 3 on November 19–20, 2025, confirming the world's single largest offshore wind farm will proceed to full construction.

Baltica 2

Baltica 2 is Poland’s largest offshore wind project under construction and forms the first phase of the Baltica Offshore Wind Farm complex developed by PGE Group and Ørsted. The 1498 MW site will generate enough clean power for about 2.4 million consumers and sits roughly 40 kilometres off the coast between Choczewo and Ustka.

Baltica 2 has a 25-year inflation-protected contract for difference (CfD) in place with Poland, and the layout includes 107 turbines rated at 14 MW each, supported by monopile foundations across an area of about 190 square kilometres. Four offshore substations and subsea export cables will move the electricity to the onshore grid connection at Osieki Lęborskie.

The European Union’s largest offshore wind farm to date continues to progress, including the first monopiles rolling off the production line in September 2025 and seabed preparation by the BOKA Falcon later that year, ahead of cable installation. The onshore substation and cable network will deliver power into the Polish Power System once commissioning begins in 2027.

An operations and maintenance base is taking shape in Ustka and is scheduled to open in 2026 to support long-term monitoring, vessel staging, and component storage. In January 2025, the project obtained PLN 11.1 billion (approximately EUR 2.6 billion) in loans from 24 Polish and international financial institutions, including the European Investment Bank and European Bank for Reconstruction and Development.

Baltica 3

Baltica 3 is the first stage of the Baltica offshore wind complex and will deliver about 1045 MW of clean power from the Polish part of the Baltic Sea. Ørsted and PGE are developing the project as a 50:50 joint venture and have secured key permits, including environmental and location approvals. The project also holds a contract for difference, which provides revenue stability for its investors. Developers expect the wind farm to begin supplying power in 2026 and will be fully operational by 2029.

Baltica 3 forms part of Poland’s move toward large-scale offshore wind and will come online a year before the larger Baltica 2 phase. The two projects together will create one of the biggest offshore wind complexes in the region. Preparatory work has advanced steadily as the partners move toward full construction. Once operational, the project will strengthen Poland’s long-term renewable energy capacity.

Sunrise Wind

Sunrise Wind is a 924 MW offshore wind farm under construction off the coast of New York and is set to become Ørsted’s largest project in the US. The site sits about 30 miles from Montauk Point and will use 84 Siemens Gamesa 8 MW turbines. Developers expect the wind farm to supply enough clean power for nearly 600,000 homes when it enters operation in 2027.

The project will also be the first US offshore wind farm to use high-voltage direct current transmission, which improves efficiency by reducing energy losses. The development has moved steadily through major milestones, including the installation of its offshore substation in September 2025. Ørsted, world’s largest offshore wind developer, leads the project and estimates it will create at least 800 construction jobs and support long-term investment in local manufacturing and workforce training.

Sunrise Wind secured its offtake agreement with NYSERDA in 2024 and fits into New York’s plan to build a carbon-free grid by 2040. The project is expected to operate until 2052 and contributes to the state's goal of reaching 9 GW of offshore wind capacity by 2035.

Greater Changhua 2b & 4

Greater Changhua 2b and 4 are Ørsted’s next major offshore wind projects in Taiwan and will add 920 MW of capacity to the country’s growing offshore wind sector. The two sites sit 35 to 60 kilometres off Changhua County in waters up to 44 metres deep and cover an area of 185 square kilometres.

They will host 66 Siemens Gamesa 14 MW turbines, and the first units began generating power in mid-2025 after installation work started earlier that year. All suction bucket jacket foundations are already in place, and turbine installation is scheduled to finish by the end of 2025.

The projects reached a final investment decision in 2023 and secured a 20-year corporate power purchase agreement with TSMC, which will take the full output once the wind farms are fully connected in 2026. They sit next to the operational Greater Changhua 1 and 2a projects, extending Ørsted’s large cluster in the region.

Early milestones, including onshore substation work and offshore construction, have progressed on time. Once completed, the wind farms will support Taiwan’s broader push to expand renewable energy and strengthen its offshore wind supply chain.

They sit next to the operational Greater Changhua 1 and 2a projects, extending Ørsted’s large cluster in the region. Commissioning of Greater Changhua 2b is now expected in the third quarter of 2026 after a damaged cable delayed the schedule.

Borkum Riffgrund 3

Borkum Riffgrund 3 is set to become Germany’s largest offshore wind farm, delivering 913 MW of clean power from the North Sea. The project lies about 110 kilometres northwest of Borkum and uses 83 Siemens Gamesa 11 MW direct-drive turbines.

Ørsted and Glennmont Partners from Nuveen Infrastructure each hold a 50 percent stake and built the project without subsidies, supported by long-term power purchase agreements with companies including Amazon, BASF, and Covestro. The final turbine was installed in early 2025, and the wind farm will have the capacity to power more than 900,000 homes once fully online.

Development followed a structured timeline that began with Ørsted securing rights in 2019 and reaching a final investment decision in 2021. Turbine manufacturing and foundation works progressed through 2023, and offshore installation started in 2024.

TenneT fully energized the DolWin5 HVDC grid connection in October 2025, clearing the way for commissioning in 2026. Borkum Riffgrund 3 builds on Ørsted’s earlier projects in the region and shares infrastructure with the nearby Gode Wind 3.

Revolution Wind

Revolution Wind is a 704 MW offshore wind farm, one of the biggest in the US, taking shape 15 nautical miles off Rhode Island and built to supply clean electricity to both Rhode Island and Connecticut. The project will use 65 turbines and is expected to power more than 350,000 homes once fully operational.

Construction is about 80 percent complete, with 45 turbines already installed. Owners Ørsted and Skyborn Renewables expect the wind farm to enter service in the second half of 2026. Work at the site continued after a temporary stop-work order in August 2025 was lifted by a court injunction the following month. Offshore installation resumed soon after, keeping the project on track for late-2026 commissioning.

Conclusion

Ørsted’s 2025 pipeline shows a company moving into its next era of global offshore wind leadership, backed by more than 20 GW in development and new technologies such as low-noise Osonic monopile installation and high-efficiency transmission systems to reduce costs and environmental impacts.

Projects like Hornsea 3, Sunrise Wind, and Greater Changhua 2b and 4 will add gigawatts of clean electricity to grids that are under pressure to decarbonize, while subsidy-free agreements and improved installation methods strengthen long-term competitiveness.
