Ørsted Nears the Finish Line in Taiwan: Ørsted Installs All Turbines at Greater Changhua 2b and 4 Offshore Wind Farm Complex - Share Price Declines
Fredericia (Denmark) - Ørsted has completed the installation of all 66 wind turbines at the Greater Changhua 2b/4 offshore wind farm in Taiwan. This marks the end of the construction phase of the 920-MW project, which is one of the largest offshore wind developments in the Asia-Pacific region and plays a key role in the region’s energy transition.
Installation completed - 920-MW project reaches key milestone
Ørsted has completed the installation of the final wind turbine at the Greater Changhua 2b/4 offshore wind farm. The 920-MW complex is located 35 to 60 kilometers off the coast of Changhua County and comprises 66 Siemens Gamesa SG 14-236 wind turbines, each with a capacity of 14 MW. Offshore construction activities began in February 2025, with turbine installation starting in April 2025. The work was carried out by turbine supplier Siemens Gamesa, which executed the installation using Cadeler’s new jack-up vessel Wind Maker.
Ørsted was awarded the Greater Changhua 2b and 4 projects in June 2018. The 583-MW Greater Changhua 4 wind farm is a joint venture between Ørsted (50%) and Cathay Life (50%). For the 632-MW Greater Changhua 2 project, Ørsted entered into an agreement with Cathay Life Insurance and Cathay Power, under which Cathay will acquire a 55% ownership stake.
“With all wind turbines now installed, we’ve achieved an important milestone in Taiwan’s offshore wind expansion and Ørsted’s 8.1 GW historically large construction pipeline,” said Per Mejnert Kristensen, CEO of Ørsted’s APAC region. Since the generation of first power in July 2025, electricity has been fed into the national grid.
Greater Changhua 2b/4 is also a pioneer for Corporate Power Purchase Agreements (CPPAs) in the region: it is the first project in the Asia-Pacific region to deliver electricity to a corporate customer under a CPPA signed in 2020.
Fast installation despite challenging conditions
The turbine installation was completed within a single season - a pace Ørsted highlights as a notable achievement. “Completing the offshore wind turbine installation for a 920 MW project within a single installation season is a significant achievement, particularly given the short weather window and challenging sea conditions in the Taiwan Strait,” said Jayaram Naidu, Managing Director of the Greater Changhua Offshore Wind Farms at Ørsted. According to Ørsted, approximately 131,576 offshore working hours have been completed since the start of turbine installation without any lost-time injuries (LTI).
Technical milestones and outlook for commercial operation
From a technical perspective, Greater Changhua 2b/4 sets several new benchmarks. It is the first offshore wind project in the Asia-Pacific region to use suction bucket jacket foundations on a large scale. These foundations are designed to keep underwater noise close to background levels during installation. In addition, the project comprises the world’s first offshore wind farms to install 14-MW turbines with 115-meter-long rotor blades - the largest of their kind.
The installation of all 66 turbines was completed in just 275 days. The focus now shifts to commissioning, testing of electrical systems, and completion of offshore cable works. Ørsted expects Greater Changhua 2b/4 to reach full commercial operation in the third quarter of 2026.
Ørsted is already active in Taiwan with several offshore projects: the company is the largest shareholder and co-owner of Formosa 1 and is also involved in the Greater Changhua 1 and 2a offshore wind farms. With the completion of Greater Changhua 2b/4, Ørsted expands its regional portfolio by another large-scale project.
Ørsted share price declines
Ørsted’s share price did not benefit from the announcement of project progress in Taiwan yesterday. The stock fell by 4.2% to €16.79 (closing price on 20 January 2026). In early trading, the stock is currently trading at €17.60.
