The Hai Long Offshore Wind Project has installed its first wind turbine at the Hai Long 3 wind farm — the final and largest of three farms within the 1,022 MW development that is on course to become Taiwan’s largest offshore wind installation and one of the largest offshore wind facilities in the Asia-Pacific region. The milestone was achieved by marine engineering contractor CDWE using a nacelle assembled at Siemens Gamesa’s Taichung facility, with the SG 14-222 turbine installed at a location 45–70 kilometres off the Changhua coast in the Taiwan Strait at water depths of 35–55 metres. With Hai Long 2A fully turbined and grid-connected, all units at Hai Long 2B installed, and Hai Long 3’s installation campaign now underway, the project consortium of Mitsui & Co., Northland Power, and Gentari International Renewables is targeting full commercial operations by the end of 2026 — a milestone that will deliver approximately 4,500 GWh of clean electricity annually to over one million Taiwanese households.

73 Nacelles, One Factory, and the SG 14-222 with Power Boost

The Hai Long project’s turbine strategy is inseparable from its local content commitment. Siemens Gamesa expanded and upgraded its Nacelle 2.0 assembly facility at the Port of Taichung specifically to serve the Hai Long programme, transforming what was a partial assembly operation into the only complete nacelle assembly factory in the Asia-Pacific region — tripling both the site’s land area and its workforce in the process. Nine Taiwanese suppliers achieved certification in Siemens Gamesa’s global supply chain as part of this industrial deepening, contributing key components including bed frames, cables, canopies, fasteners, hub castings, spinners, towers, and transformers. At the time of the Hai Long 3 first installation, all 73 nacelles for the entire project had been assembled at Taichung and were either already installed or in the process of being transported to the offshore site.

The turbine model employed throughout is the Siemens Gamesa SG 14-222 — a direct-drive offshore machine with a 222-metre rotor diameter and a nameplate rating of 14 MW, boosted to up to 15 MW per unit through Siemens Gamesa’s Power Boost technology, which temporarily increases output during favourable wind conditions. At the Hai Long site, average wind speeds of 10–11 metres per second make it one of the highest-yielding offshore wind locations in Asia. The 73 turbines across the three farms — 21 at HL2A (294 MW), 16 at HL2B (224 MW), and 36 at HL3 (504 MW) — are all mounted on jacket foundations, the preferred foundation structure for the water depths and seabed conditions of the Changhua coastal waters. Tim Kittelhake, Hai Long Project CEO and project director, has framed the Hai Long 3 first installation as a demonstration of the synergy between the project team and local contractors as they move steadily toward full grid connection.

The Developer Consortium: Mitsui, Northland, Gentari, and the Project’s Financial Architecture

The Hai Long Offshore Wind Project is owned by a consortium in which Mitsui & Co. holds 40 per cent, Northland Power holds 30.6 per cent, and Gentari International Renewables — the clean energy subsidiary of Malaysia’s PETRONAS, which acquired its stake in December 2023 at a consideration of approximately CAD 1 billion — holds the remaining 29.4 per cent indirect equity interest. The Final Investment Decision was made by Mitsui and Northland on 22 September 2023, with project financing reaching close through a US$3.6 billion debt facility arranged across 16 international and local financial institutions including Crédit Agricole CIB, ING, Société Générale, and the Japan Bank for International Cooperation. Total project costs are estimated at approximately US$6.5 billion — making Hai Long one of the most capital-intensive individual offshore wind projects in Asia-Pacific history, and the recipient of the PFI Awards’ Asia-Pacific Offshore Wind Deal of the Year for 2023.

The revenue structure underpinning the financing reflects Taiwan’s hybrid offshore wind procurement model. Hai Long 2A’s 294 MW is sold to Taiwan Power Company (Taipower) under a 20-year Feed-in-Tariff PPA signed in February 2019 — a contract that provides a stable, government-backed revenue floor for the project’s most mature phase. Hai Long 2B and 3, representing the remaining 728 MW, are sold to an undisclosed investment-grade private counterparty under a 30-year Corporate Power Purchase Agreement signed in July 2022 at a price more favourable than the original 2018 auction tariff — a commercial outcome that reflects both the long-term demand from Taiwanese industrial and corporate buyers for large-scale renewable power and the developers’ ability to negotiate terms that exceed the auction baseline.

Sequential Construction: Hai Long 2A Complete, 2B Installed, and 3 Underway

The Hai Long project has been delivered in a carefully sequenced three-farm construction programme that allows each phase to inform the next while sharing the offshore logistics, marine vessel fleet, and supply chain infrastructure mobilised for the overall campaign. Hai Long 2A — the smallest farm at 294 MW — has been fully completed and grid-connected, with its turbines already delivering power to Taipower’s network. The project’s first power was delivered to the grid on 12 June 2025, confirming the successful commissioning of both the onshore substation in the Changhua Binhai Industrial Zone — equipped with four transformers serving all three farms — and the offshore substations. Hai Long 2B, at 224 MW, has had all its turbines installed and was pending final commissioning works as of the time of the Hai Long 3 first installation milestone.

Hai Long 3 — at 504 MW the largest of the three farms, and by output the decisive component in Hai Long’s claim to be Taiwan’s largest offshore wind project — is now in active turbine installation with CDWE as the marine contractor. The installation of the first SG 14-222 unit at HL3 marks the beginning of a campaign that will see 36 turbines placed at distances of 50–70 kilometres from shore in water depths of 40–55 metres — conditions that represent the more challenging outer edge of the Hai Long lease area. The project developers have committed to matching the local assembly intensity of the construction phase with local operations and maintenance activities once commercial operation begins, embedding the supply chain development that has characterised Hai Long’s construction in the long-term operational economic model of the project.

Taiwan’s Offshore Wind Build and Hai Long’s Role in the National Energy Transition

The Hai Long Offshore Wind Project sits at the centre of Taiwan’s most ambitious phase of offshore wind development. Taiwan’s government has targeted 15 GW of offshore wind capacity to be constructed between 2026 and 2035, and the long-term plan envisions 40–55 GW of installed offshore wind by 2050 as the island territory pursues its net-zero carbon emissions commitment. Hai Long, at 1,022 MW, represents the first offshore wind project in Taiwan to exceed 1 GW — and its full grid connection by end of 2026 will supply approximately 4,500 GWh of clean electricity annually, displacing a significant share of the island’s historically coal and gas-dependent generation mix. This push for renewable energy is further highlighted by the official inauguration of the 640 MW Yunlin offshore wind farm, a major project that now contributes significantly to Taiwan’s sustainable power grid.

Taiwan’s offshore wind ambitions are geographically and strategically compelling. The Taiwan Strait is consistently ranked among the highest-wind offshore environments in the world, with average wind speeds substantially exceeding those of the North Sea zones that defined the first generation of European offshore wind development. The Changhua coast — where Hai Long, Changfang & Xidao, Greater Changhua, and multiple other utility-scale projects are clustered — has emerged as one of the world’s most active offshore wind construction zones, with international developers from Ørsted (Denmark), Equinor (Norway), and Copenhagen Infrastructure Partners alongside Asian developers competing for Taiwan Power Company and corporate offtake. Hai Long’s successful delivery of its local content commitments — building the only complete nacelle assembly facility in APAC at Taichung, certifying nine Taiwanese companies in a global offshore wind supply chain, and deploying a Taiwanese marine contractor in CDWE — will be closely watched as a template for the local content regimes that Taiwan’s subsequent auction rounds have embedded as increasingly demanding conditions of project development.
