Located 35-60 kilometres off the coast of Changhua County, the offshore wind farms consist of 66 Siemens Gamesa 14-236 14 MW wind turbines. Once fully operational, the wind farms will supply substantial renewable electricity to the corporate offtaker, accelerating Taiwan’s offshore wind capacity expansion and supporting the island’s transition to net-zero.
Jayaram Naidu, Managing Director of Ørsted’s Greater Changhua offshore wind farms, says: “Achieving first power just three months since the first foundation was installed in April reflects Ørsted’s strong project execution. Despite ongoing challenges in the global wind industry, we’ve stayed on course by working closely with our suppliers and contractors. This milestone marks the beginning of the next phase — safely completing construction, energising additional wind turbines, and progressing steadily toward full commercial operation.”
Christy Wang, Chairperson of Ørsted Taiwan, says: “First power from Greater Changhua 2b and 4 isn’t only a key milestone for the project, it also reaffirms Taiwan’s leadership in offshore wind across the Asia-Pacific region. All of the renewable energy generated by the 920 MW wind farms will be supplied to TSMC through our 20-year corporate power purchase agreement, aiding our corporate customer in advancing its climate action and sustainability goals.”
Since final investment decision in March 2023, the project has progressed rapidly, with all 66 suction bucket jacket foundations and 32 wind turbines already installed. Two onshore substations and one offshore substation have been energised, with cable installation proceeding as schedules.
Beyond renewable energy, the project is the first in Taiwan to employ advanced piling-free suction bucket jacket (SBJ) foundations, which is in line with Ørsted’s commitment to continue introducing innovative foundation technology. The SBJ technology produces almost no noise during installation and can be fully removed at decommissioning, minimising the potential impact on marine ecosystems.
Greater Changhua 2b and 4 is Ørsted’s second gigawatt-size offshore wind project in Taiwan, following the 900 MW Greater Changhua 1 and 2a offshore wind farms that came into operation in April 2024. With this addition, Ørsted’s total installed capacity in the Greater Changhua offshore wind zone will reach 1.82 GW — enough renewable electricity to power approximately two million Taiwanese households annually, or equivalent to avoiding approximately 3.5 million tons of carbon dioxide emissions each year, making Ørsted the largest contributor to Taiwan’s offshore wind build-out to date.
