Ørsted completes cable works at Taiwan offshore wind farm

Ørsted has completed the installation and energisation of all inter-array cables at its 920-MW Greater Changhua 2b and 4 offshore wind project in Taiwan, Offshore Energy writes.

The developer said all 42 turbines at the project’s second phase, the 583-MW Greater Changhua 4 wind farm, are now connected to Taipower’s grid and generating electricity.

“We’re continuing commissioning and grid integration works to ensure that all the complex systems of the offshore wind farms — from subsea cables to offshore substations — work together seamlessly, enabling reliable operation day in and day out,” Ørsted said on social media.

Located 35km to 60km off the coast of Changhua County, the Greater Changhua 2b and 4 project comprises 66 Siemens Gamesa SG 14-236 turbines.

According to Ørsted, the development is the first offshore wind farm globally to install 14-MW turbines equipped with 115-metre blades.

Offshore construction began in February 2025. The first turbine at Greater Changhua 2b was installed in April last year, shortly after the first suction bucket jacket foundation was deployed by Cadeler’s vessel Wind Maker.

The wind farm generated first power in July 2025. The 66th and final turbine was installed in January this year.

The project is expected to become fully operational in the third quarter of 2026.

Once completed, Greater Changhua 2b and 4 will supply renewable electricity to Taiwan Semiconductor Manufacturing Company under a corporate power purchase agreement signed in 2020.
