Ørsted has installed the final turbine at its 920-megawatt Greater Changhua 2b and 4 offshore wind farms off the coast of Taiwan, marking the completion of a key phase of construction, the company said.
The projects are located around 35 to 60 kilometres offshore Changhua County. Ørsted said the wind farms comprise 66 SG 14-236 turbines supplied by Siemens Gamesa, installed using Cadeler’s Wind Maker installation 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 Ørsted’s historically large construction portfolio of 8.1GW,” Per Mejnert Kristensen, Ørsted’s regional director for Asia Pacific, said in a statement.
The company said turbine installation for the full 920MW capacity was completed within a single construction season, despite challenging conditions in the Taiwan Strait.
“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,” Jayaram Naidu, programme director for Ørsted’s Greater Changhua offshore wind farms, said.
Ørsted said the project has recorded about 131,576 offshore working hours without any work-related accidents resulting in absences.
The Greater Changhua 2b and 4 wind farms began generating electricity in July 2025 under a long-term power purchase agreement signed in 2020. The project is the first in the Asia-Pacific region to deploy suction bucket foundations at scale without ramming, with the company saying underwater noise levels were kept close to natural background levels.
Ørsted added that the development is also the first globally to install 14-megawatt turbines equipped with 115-metre blades, completing the installation of all 66 turbines within 275 days.
Construction activity will now focus on commissioning, electrical testing and the completion of cable installation. Full commissioning of the wind farms is expected in the third quarter of 2026, the company said.
