The Hai Long project, located off the coast of Changhua, is consolidating its position as Taiwan’s largest offshore wind farm, with a total installed capacity of more than 1 GW. It is estimated to be fully connected to the grid by 2026, strengthening the country’s role as a leader in offshore wind energy in the Asia-Pacific region.
The development of the Hai Long project
Developed by Mitsui & Co, Northland Power and Gentari Renewables, the project is incorporating Siemens Gamesa technology with SG 14-222 turbines, capable of reaching 15 MW thanks to Power Boost. This collaboration has driven key infrastructure investments, such as the expansion of the nacelle assembly plant at Taichung Port, now the largest of its kind in APAC.
The assembly of critical components has progressed smoothly. By the end of 2025, fourteen wind turbines have been installed and 37 jacket foundations were completed. Century Wind Power successfully delivered 21 locally manufactured three-legged jacket foundations, the largest ever produced in the country, integrating for the first time a hydraulic clamp system designed to withstand extreme loads and facilitate precise alignment.
During 2025, energization of the Hai Long 2 offshore substation, installation of the substation for Hai Long 3 and the first test deliveries of electricity to the Taipower grid were achieved. The generated power is uprated to 220 kV offshore and then transformed to 161 kV onshore before being integrated into the ChangOne Grid substation.
The project has been key to the development of local capabilities in offshore wind energy. Century Wind Power’s “Twin Tower,” the first open-pit heavy lift facility for extra-large deepwater foundations, has enabled scaling up domestic manufacturing. Taiwanese companies such as CSBC, Century Iron and Steel and Century Hwa Shin have actively contributed.
Scheduled for completion in 2026, Hai Long will be the first Taiwanese offshore wind farm to exceed 1 GW of grid-connected capacity. This achievement reinforces Taiwan’s strategic role in the regional energy transition, providing clean energy to more than one million households and consolidating its supply chain as a benchmark in the APAC offshore market.
