Offshore wind farms Greater Changhua 2b and 4, developed by Ørsted off the west coast of Taiwan, have completed the installation of their 66 Siemens Gamesa SG 14-236 DD offshore turbines. This phase concludes after an intensive season of offshore work started in April 2025, using the installation vessel Wind Maker installation vessel.
With a total capacity of 920 MW, these wind farms, located between 35 and 60 km from Changhua County, marked several technical achievements in the region. Among them is the use of large-scale suction bucket foundations, a pile-less solution that minimizes underwater acoustic impact.
A technical operation under challenging conditions
The director of wind projects at Ørsted Taiwan, Jayaram Naidu, highlighted the complexity of the offshore environment in the Taiwan Strait and the achievement of completing the entire installation in a single season. The process involved 131,576 hours of offshore work with no lost-time incidents, reaffirming the commitment to operational safety at every stage of the project.
As of July 2025, the Greater Changhua Greater Changhua 2b and 4 already supplies renewable electricity to the national grid as part of a corporate power purchase agreement signed in 2020. The final commissioning, including electrical testing and connection of submarine cablesis progressing progressively. Full commercial operation is expected to begin in the third quarter of 2026.
Offshore turbines to drive energy shift
The SG 14-236 units, with 115-meter blades, represent one of the most advanced models in the global wind industry. Ørsted, with more than 18 GW of renewable capacity in operation or under development worldwide, thus reinforces its key role in the Asia-Pacific energy transition.
Per Mejnert Kristensen, managing director of Ørsted’s APAC region, noted that this breakthrough is integrated within the 8.1 GW construction portfolio that the company leads globally.
In addition, the project includes strategic agreements with local investors such as Cathay Life, strengthening national participation in the growth of the offshore sector.
