In May 2025, Heerema Marine Contractors’ heavy-lift vessel Aegir completed the installation of all 24 SBJ foundations for Greater Changhua 2b. The vessel is now installing the final five foundations for Greater Changhua 4, as indicated by AIS data. These foundations, supplied by Petrovietnam Technical Services Corporation (PTSC) and HSG Sungdong, use piling-free SBJ technology, a first for large-scale offshore wind farms in the Asia-Pacific region, minimizing seabed disturbance and noise.
Wind turbine installation is also advancing, with 22 of 66 Siemens Gamesa SG 14-236 DD turbines in place, as reported by Ørsted. The first of these 14 MW turbines, the largest of their kind in the Taiwan Strait, was installed in April 2025. “Progress is advancing well with the onshore works, and we anticipate the offshore installation to be completed by the end of 2025,” said Jayaram Naidu, Managing Director of Greater Changhua Offshore Wind Farms at Ørsted.
The second onshore substation has been energized and connected to the Taiwan Power Company (Taipower) grid, enhancing system integration. This milestone follows the energization of the first onshore substation in April 2025, supporting the project’s grid connectivity goals.
Located adjacent to the fully operational 900 MW Greater Changhua 1 and 2a wind farms, also developed by Ørsted, Greater Changhua 2b and 4 are set to be completed by the end of 2025, with full grid connection expected in 2026. The project will contribute significantly to Taiwan’s renewable energy targets, delivering clean energy to power millions of households.
Ørsted’s use of innovative SBJ foundations and advanced turbines underscores its commitment to sustainable energy development. The project, supported by a 20-year corporate power purchase agreement signed in July 2020, reinforces Taiwan’s position as a leader in offshore wind in the Asia-Pacific region.
