The Hai Long Offshore Wind Project, located off the coast of Changhua County in Taiwan, is one of the country’s largest renewable energy developments. This is with a planned capacity of over 1 GW. The project is divided into Hai Long 2A, 2B, and 3. Siemens Gamesa’s SG 14-222 DD turbines also feature in Hai Long’s development. A development spearheaded by Canada’s Northland Power in partnership with Taiwan’s Yushan Energy. Also involved in the project are Mitsui & Co., and Gentari.
The first Siemens Gamesa 14-222 DD wind turbine were installed at Taiwan’s Hai Long 2A offshore wind farm in April 2025. This is as the project continues to form part of Taiwan’s broader offshore wind development landscape.
CSBC-DEME Wind Engineering JV (CDWE) completed the first turbine installation using the Blue Wind, a vessel owned by Shimizu Corporation. CDWE is handling the transport and installation of foundations, turbines, and substations across both Hai Long 2 and Hai Long 3 wind farms.
Other offshore wind developments in Taiwan include the Formosa 4 Offshore Wind Farm which recently reached a key milestone after latest award of jacket foundations, substation, and scour protection works contract to CDWE (Sept 25, 2025). CDWE is DEME‘s Taiwanese JV, and is also involved in the Hai Long project in the same capacity. The contract was awarded by Formosa’s developer, Synera Renewable Energy (SRE).

Hai Long Offshore Wind Project Timeline
2012-2017: Early Development
Project area off Changhua coast in Taiwan was identified and secured by Yushan Energy (Taiwanese developer) and Canada’s Northland Power
Initial feasibility studies, ocean assessments and site investigations were also conducted
2018: Zonal Development Approval
Taiwan government awards grid capacity allocation for Hai Long 2 & 3 as part of its offshore wind Phase 2 tender
Project capacity was announced at 1,044 MW
2019: PPAs and Partnerships
Power Purchase Agreements (PPAs) signed:
- Hai Long 2A: 300 MW, 20-year Feed-in Tariff (FiT) with Taipower
- Hai Long 2B and 3: 744 MW, 30-year Corporate PPA
Northland Power also takes majority stake. Yushan Energy retains minority share
2020: Environmental Approvals
EIA approved by Taiwan’s Environmental Protection Administration
Local supply chain plan also formalized afterwards. These covered foundation jackets, cables, and nacelle assembly in Taiwan
2021: Grid Connection Agreements
Formal agreements with Taipower to connect Hai Long 2 & 3 to the national grid
2022: Financing & Supply Contracts
Financial structuring begins. Also announced were discussions with financiers
Siemens Gamesa confirmed as turbine supplier for the SG 14-222 DD, 14 MW unit model
First nacelle assembly line for 14 MW turbines set up in Taichung, Taiwan
2023: Final Investment Decision (FID)
Northland Power & partners announce FID on Hai Long Offshore Wind at USD 6.5 billion
Debt financing was also secured from an international consortium of banks
2024: Offshore Construction Starts
Offshore site preparation starts. Cabling routes also marked
Foundation fabrication at local yards commences
April 2025: First Turbine Installed at Hai Long 2A
Siemens Gamesa installs the first SG 14-222 DD turbine at Hai Long 2A
This also marks Asia’s first deployment of the SG 14-222 DD turbine type
June 2025: First Power
Hai Long project delivers first electricity to Taiwan’s grid
Milestone celebrated as project enters commissioning phase
August 2025: Jacket Foundations Delivered
Century Wind Power delivers 21 jacket foundations for Hai Long
September 2025
Multiple turbines operational and feeding into Taiwan’s national grid
Construction of remaining turbines and array cables ongoing
Full commissioning of Hai Long 2A (300 MW) expected by late 2025 to early 2026
Hai Long 2B and 3 (744 MW) expect full commissioning by 2027-2028
A Total of 73 Siemens Gamesa 14-222 DD Turbines will be in Place Once Installation is Complete
The Hai Long project is being developed in phases. The first phase, Hai Long 2A, now has its first turbine standing. The full development will eventually consist of 73 Siemens Gamesa 14-222 DD turbines. This makes Hai Long one of the largest offshore wind farm in Taiwan.
The nacelle for the turbine was assembled at Siemens Gamesa’s Taichung facility. Also noteworthy is that the facility began expanded operations in January 2024. As a result, this marks the first time an SG 14-222 nacelle produced in Taiwan has been installed at sea.
In addition to the nacelle, the turbine includes components made in Taiwan, including towers and blade resin. This local sourcing also supports Taiwan’s goal of building a strong offshore wind supply chain.
Prior to the first turbine installation at Hai Long offshore wind farm, CDWE had also completed the installation of the offshore topside structure for Hai Long 3.
In a nutshell, the Hai Long offshore wind project will help boost the country’s renewable energy supply and also reduce its reliance on fossil fuels.
