The last turbine at the 920MW Greater Changhua 2b and 4 offshore wind farms off Taiwan was installed last week.
Orsted said the milestone marked the completion of a key phase of construction at the site located 35–60km off Changhua County.
The company added that the project features 66 SG 14-236 turbines installed by Siemens Gamesa using Cadeler’s Wind Maker vessel.
“Now that all wind turbines have been installed, we have reached an important milestone in the expansion of the offshore wind industry in Taiwan and in the construction of Orsted’s historically large construction portfolio of 8.1GW,” said Per Mejnert Kristensen, regional director for Asia Pacific at Ørsted.
“To complete the installation of the offshore wind turbines for a 920MW project in just one season is an unprecedented achievement, especially given the highly volatile weather and challenging sea conditions in the Taiwan Strait,” added Jayaram Naidu, programme director for Orsted’s Greater Changhua offshore wind farms.
The project has logged about 131,576 offshore working hours without any work-related accidents with absences.
The wind farms began producing power in July 2025 under a long-term power purchase agreement signed in 2020.
The scheme is the first in Asia Pacific to use suction bucket foundations without ramming on a large scale, with underwater noise kept close to background levels.
It is also the first globally to install 14MW turbines with 115-metre blades, while completing 66 turbine installations in 275 days.
Work now focuses on commissioning, electrical testing and completing cable installation, with full commissioning expected in the third quarter of 2026.
