Ørsted's Greater Changhua 2b & 4 Offshore Wind Project Nears Completion with 61 Foundations Installed
Key Insights
Ørsted's Greater Changhua 2b & 4 offshore wind farms in Taiwan are nearing completion, with 61 out of 66 jacket foundations already installed.
Heerema Marine Contractors' vessel Aegir has completed foundation installation for Changhua 2b and is now working on the final units for Changhua 4.
A third of the Siemens Gamesa SG 14-236 DD turbines are in place, marking progress toward the project's 920 MW capacity.
The project is the first in the Asia-Pacific region to use suction bucket jacket foundations and Siemens Gamesa's latest turbine technology.
The jacket foundation installation for Ørsted’s Greater Changhua 2b & 4 offshore wind farms is in its final stages, with 61 out of 66 foundations now installed off the coast of Taiwan. The project, which began offshore construction in February 2025, is a significant milestone for Taiwan’s renewable energy ambitions and Ørsted’s global portfolio. Heerema Marine Contractors’ heavy-lift vessel Aegir has played a pivotal role, completing the installation of all 24 foundations at the Greater Changhua 2b site and now focusing on the remaining five for Changhua 4. The foundations, delivered by Petrovietnam Technical Services Corporation (PTSC) and HSG Sungdong, utilize suction bucket jacket technology, a first for large-scale offshore wind in the Asia-Pacific region.
On the turbine front, 22 of the 66 Siemens Gamesa SG 14-236 DD units are already in place, with the first installed in April 2025. These turbines, with a capacity of 14 MW each, are among the most advanced in the industry, underscoring the project’s technological leadership. The second onshore substation has also been energized and connected to Taiwan’s Taipower grid, ensuring seamless integration of the wind farms’ output.
The Greater Changhua 2b & 4 projects, totaling 920 MW, are adjacent to the operational 900 MW Greater Changhua 1 and 2a wind farms, also developed by Ørsted. This cluster positions Taiwan as a key player in offshore wind energy in the region. The project’s progress reflects Ørsted’s commitment to expanding renewable energy capacity and Taiwan’s strategic push to diversify its energy mix.
