Ørsted has completed the main construction works on the 920 MW Greater Changhua 2b and 4 offshore wind farms in Taiwan, bringing the company’s installed capacity across the Greater Changhua cluster to 1.82 GW.
The projects are expected to enter full commercial operation in late Q3 2026, once remaining commissioning work and regulatory requirements are completed.
Ørsted is developing the project with Taiwanese insurer Cathay Life Insurance and a wider group of domestic and international suppliers and financial institutions.
The latest project adds another large block of renewable generation to Taiwan’s developing offshore wind sector, while increasing Ørsted’s presence in a market where it opened its first local office a decade ago.
The 920 MW development follows Ørsted’s 900 MW Greater Changhua 1 and 2a wind farms, which entered operation in 2024.
Construction has included the installation of suction bucket jacket foundations, a technology intended to reduce the need for conventional foundation piling. The project has also involved the development of local operations and maintenance capability at Ørsted’s hub in the Port of Taichung.
Patrick Harnett, Ørsted’s chief construction officer, said the project demonstrated what could be achieved through the combination of offshore wind experience and a strong supply chain.
“Delivering 920 MW of offshore wind capacity at this scale and complexity is a major achievement,” he said.
The financing structure also highlights the increasing role of Taiwanese institutional capital in offshore wind. Greater Changhua 4, with capacity of 583 MW, is owned equally by Ørsted and Cathay Life. Cathay has also agreed to acquire a 55% stake in the 632 MW Greater Changhua 2 project, subject to completion following commissioning.
Thirty domestic and international financial institutions supported the project’s financing, while the development includes a corporate power purchase agreement linked to Taiwan’s semiconductor industry.
For Taiwan, the project adds generation capacity to a power system facing growing electricity demand from industry and the wider economy. For Ørsted, it represents another large-scale project within its global 8.1 GW construction programme.
“The completion of Greater Changhua 2b and 4 is a significant milestone in the delivery of Ørsted’s strategy,” said group CEO Rasmus Errboe.
With construction now substantially complete, attention turns to commissioning and the transition from project delivery to long-term operation – the stage at which the project’s generation, grid integration and local supply chain arrangements will be tested in practice.
