Orsted has completed the installation of all wind turbines at its 920 MW Greater Changhua 2b and 4 offshore wind farms in Taiwan, marking a major milestone for the Asia-Pacific offshore wind market.
The final turbine was installed last week, concluding the wind turbine build-out phase of one of the region’s largest offshore wind projects. Located around 35 to 60 kilometres off the coast of Changhua County, the Greater Changhua 2b and 4 projects feature 66 Siemens Gamesa SG 14-236 wind turbines, each with a capacity of 14 MW.
Offshore construction of the project began in February 2025, while turbine installation started in April 2025. The installation work was carried out by Siemens Gamesa using Cadeler’s installation vessel Wind Maker. Orsted said the completion of all turbine installations within a single installation season was achieved despite limited weather windows and challenging sea conditions in the Taiwan Strait.
The offshore wind farms are the first in the Asia-Pacific region to deliver renewable electricity to a corporate customer under a corporate power purchase agreement signed in 2020. Since achieving first power in July 2025, the project has been supplying renewable energy to Taiwan’s national grid.
Per Mejnert Kristensen, CEO of Orsted’s Asia-Pacific region, said the milestone supports both Taiwan’s offshore wind ambitions and Orsted’s global construction pipeline, which currently stands at 8.1 GW.
Jayaram Naidu, Managing Director of the Greater Changhua Offshore Wind Farms, highlighted the complexity of the installation campaign, noting that the successful execution reflects strong coordination across marine operations, logistics, and installation planning, supported by rigorous risk management and a strong safety culture.
Orsted also reported a strong safety record during the turbine installation phase, with around 131,576 offshore working hours completed without any lost-time injuries.
The project now moves into the next phase, which includes wind turbine commissioning, electrical system testing, and the completion of offshore cable works. Full commercial operation of Greater Changhua 2b and 4 is expected in the third quarter of 2026.
The project has already delivered several industry firsts. It is the first offshore wind project in the Asia-Pacific region to deploy piling-free suction bucket jacket foundations at scale, significantly reducing underwater noise during installation. It is also the first offshore wind project globally to install 14 MW turbines equipped with 115-metre-long blades, setting a new benchmark for large-scale offshore wind deployment. The full installation of all 66 turbines was completed in just 275 days.
