Ørsted has completed the installation and energisation of all 66 array cables at the 920 MW Greater Changhua 2b and 4 offshore wind farms in Taiwan, marking another step toward full commercial operations in one of Asia’s largest offshore renewable energy developments.
The Danish offshore wind developer also confirmed that all 42 turbines at the 583 MW Greater Changhua 4 project are now connected to Taiwan Power Company’s grid and generating electricity offshore Taiwan.
Offshore Installation Campaign Advances
The latest milestone reflects the rapid pace of offshore commissioning work in Taiwanese waters, where vessel coordination, subsea cable installation, and turbine integration continue to intensify across the project zone.
Array cables act as the offshore wind farm’s internal nervous system, linking turbines to offshore substations before electricity is transmitted ashore. Completing all 66 cable connections removes one of the most technically demanding phases of the offshore construction campaign.
For project cargo and offshore logistics contractors, the achievement highlights how Taiwan continues to mature as a regional offshore wind hub. Installation campaigns in the Taiwan Strait require tight scheduling around seasonal weather windows, vessel availability, and port infrastructure constraints.
The Greater Changhua developments have relied on a broad offshore supply chain involving heavy lift vessels, cable lay ships, subsea engineering teams, and grid specialists. In practical terms, energising cables and connecting turbines means multiple offshore systems are now operating together under live conditions.
Grid Integration Work Continues
Ørsted said commissioning and grid integration activities remain ongoing as engineers continue synchronising subsea cables, offshore substations, and turbine systems to ensure stable long term operations.
That phase can often resemble testing every circuit in a floating industrial city before handing over the keys. Offshore wind farms may appear complete once turbines are spinning, but final commercial operation depends on months of integration testing and reliability checks.
Taiwan has positioned offshore wind as a strategic component of its industrial and energy transition plans, particularly as manufacturers and technology companies seek greater access to low carbon electricity supplies.
Greater Changhua 2b and 4 are expected to contribute renewable power to Taiwan’s energy mix while supporting continued offshore construction activity and marine logistics demand across the region.
