All Wind Turbines Installed at Ørsted's 920 MW Greater Changhua 2b and 4 Offshore Wind Farms in Taiwan

Since achieving first power generation in July 2025, the Greater Changhua 2b and 4 offshore wind farms have been steadily delivering clean energy to Taiwan's national power grid.

Ørsted announced that the installation of the last wind turbine at the 920 MW Greater Changhua 2b and 4 offshore wind farms in Taiwan was completed last week, marking a successful conclusion of the wind turbine build-out and a landmark milestone for the offshore wind industry in the Asia-Pacific region.

Located 35–60 kilometres off the coast of Changhua County, Taiwan, Greater Changhua 2b and 4 comprises 66 state-of-the-art 14 MW SG 14-236 wind turbines and is set to reach commercial operation in Q3 2026. Offshore construction of the 920 MW project began in February 2025, with wind turbine installation commencing in April last year, executed by turbine supplier Siemens Gamesa using Cadeler's newly built installation vessel, Wind Maker.

The Greater Changhua 2b and 4 offshore wind farms are the first of their kind in the Asia-Pacific region to supply renewable electricity to Ørsted's corporate customer on the project under a corporate power purchase agreement signed in 2020. Since achieving first power in July 2025, the project has been delivering renewable energy to the national grid.

Throughout the entire construction phase, the Greater Changhua 2b and 4 offshore wind farms have adhered to stringent safety standards. Since the commencement of turbine installation works, the projects have accumulated approximately 131,576 offshore working hours with zero lost-time injuries (LTIs), demonstrating an outstanding safety performance.

Per Mejnert Kristensen, CEO of Region APAC at Ørsted, says: "With all wind turbines now installed, we've achieved an important milestone in Taiwan's offshore wind expansion and Ørsted's 8.1 GW historically large construction pipeline."

Jayaram Naidu, Managing Director of Greater Changhua Offshore Wind Farms at Ørsted, says: "Completing the offshore wind turbine installation for a 920 MW project within a single installation season is a significant achievement, particularly given the short weather window and challenging sea conditions in the Taiwan Strait. It reflects our disciplined execution, rigorous risk management, and close coordination across marine operations, logistics, and installation planning, all underpinned by a strong safety culture."

Safety performance is embedded into all phases in the Greater Changhua 2b and 4 offshore wind farms, from contractor selection over vessel mobilization to offshore operations. Since the start of the wind turbine installation campaign, a total of approximate 131,576 working hours offshore with zero lost-time injuries (LTIs) has been achieved.

The focus now for the project is to efficiently continue the commissioning of the wind turbines, the electrical system testing, and the finalisation of offshore cable works. Full commercial operation of Greater Changhua 2b and 4 is expected in Q3 2026.

The project has several technical achievements as of today:

• First offshore wind project in the Asia-Pacific region to deploy piling-free suction bucket jacket foundations at scale, keeping the underwater noise close to background levels during installation.
• First offshore wind farms globally to install 14 MW wind turbines with 115-metre-long blades – the largest of their kind in the world – setting a new benchmark for large-scale wind turbine component deployment.
• Completion of the 66-wind turbine installation campaign in approximately 275 days.
  
  

The Greater Changhua 2b and 4 offshore wind farms are the world's first offshore wind projects to deploy large-scale 14 MW turbines, featuring 115-meter-long blades, setting a new global benchmark for the installation of next-generation large-capacity offshore wind turbines.

Offshore Wind Farms in Commercial Operation

• Ørsted is the largest shareholder (35% equity stake) of Taiwan's first offshore wind project, Formosa 1 Offshore Wind Farm. The project's second construction phase was completed at the end of 2019 and achieved commercial operation in early 2020, expanding installed capacity from 8 MW to 128 MW.
• The Greater Changhua 1 and 2a offshore wind farms located 35 to 60 kilometers off the coast of Changhua, have a combined grid-connected capacity of 900 MW. The projects generate enough clean electricity annually to supply approximately one million Taiwanese households.
• The Greater Changhua 1 offshore wind farms has an installed capacity of 605 MW. Ørsted holds a 50% ownership stake, with the remaining 50% held by a joint venture between international infrastructure investor CDPQ (Caisse de dépôt et placement du Québec) and Taiwan's Cathay Sustainable Private Equity Fund.
• At the Greater Changhua 1 Offshore Wind Farm, Ørsted is conducting the world's first coral propagation feasibility study, ReCoral by Ørsted™, leveraging offshore wind turbine substructures in tropical waters to explore the creation of new coral habitats.
  
  

Offshore Wind Farms Under Construction

• In June 2018, Ørsted secured its second large-scale offshore wind development in Taiwan through a competitive bidding process: the 920 MW Greater Changhua 2b and 4 Offshore Wind Farms. In July 2020, Ørsted signed a corporate power purchase agreement (CPPA) with Taiwan's largest semiconductor manufacturer.
• The Greater Changhua 4 Offshore Wind Farm has an installed capacity of 583 MW, with Ørsted holding 50% equity, and the remaining 50% owned by Cathay Life Insurance.
• Ørsted has entered into agreements with Cathay Life Insurance Co., Ltd. and its subsidiary Cathay Power Co., Ltd. (collectively, "Cathay") to jointly invest in a 55% equity stake in the Greater Changhua 2 Offshore Wind Farm, which has a total installed capacity of 632 MW. The transaction is expected to be completed upon commercial operation of the wind farm in the Q3 2026.
