Taiwan has completed installation of all 73 turbines at the Hai Long offshore wind farm, bringing total capacity to 1,022 MW — with every unit already feeding electricity into the grid. The project in the Taiwan Strait is now entering its final phase ahead of full commercial operations in 2027. According to offshorewind.biz, developers expect to receive the remaining regulatory approvals in the first half of 2027.
Key figures:
- 1,022 MW — combined capacity across all three Hai Long phases.
- 73 Siemens Gamesa SG 14-222 DD turbines installed and grid-connected.
- 45–70 km — distance from the Changhua County coastline.
- Over 1 million Taiwanese households — projected electricity coverage.
Three Phases in the Taiwan Strait
Hai Long sits approximately 45–70 kilometers off the coast of Changhua County and is developed in three phases: Hai Long 2A at 294 MW, Hai Long 2B at 224 MW, and Hai Long 3 at 504 MW. All sections use the 14 MW Siemens Gamesa SG 14-222 DD turbine.
The first phase, Hai Long 2A, was connected to the grid in late 2025. All 16 turbines of phase 2B were installed the following year, while construction of the largest phase, Hai Long 3, began in March 2026. All 73 machines are now generating power, though the project will not reach full commercial operation status until final permits are in hand.
Ownership and Construction
The project has an international ownership structure: Japan’s Mitsui & Co. holds 40%, Canada’s Northland Power 30.6%, and Malaysia’s Gentari International Renewables 29.4%. It was Northland Power that announced on October 15 the completion of turbine installation, noting that the project continues to await the conclusion of regulatory approval processes.
Transportation and installation of foundations, turbines, and offshore substations is handled by the joint venture CSBC-DEME Wind Engineering (CDWE). The company completed all jacket foundation installations in August 2025, having driven 219 monopiles and set the foundations for two offshore substations.
A 30-Year Power Purchase Agreement and a Benchmark for Asia
At full capacity, Hai Long is expected to supply electricity to more than 1 million Taiwanese households. The project operates under a 30-year power purchase agreement — a contract horizon that provides predictable cash flows and simplifies debt servicing for lenders.
For Asia, this is a landmark development: the region now has a working reference project at over one gigawatt, deploying 14 MW-class turbines on jacket foundations under the demanding conditions of the Taiwan Strait.
