Ørsted has finished installing all 66 wind turbines at the 920 MW Greater Changhua 2b and 4 wind project, a major construction milestone that transitions the offshore wind farm into full commissioning. The project is located 35–60 kilometres off the coast of Changhua County, Taiwan.
“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.” – Jayaram Naidu, Managing Director of Greater Changhua Offshore Wind Farms at Ørsted
Crews are now shifting focus from heavy-lift installation to the detailed work of commissioning the wind turbines, electrical system testing, and the finalization of offshore cable works. Full commercial operation is expected in Q3 this year.
Reaching turbine installation completion signals that the project’s most schedule-sensitive activities are behind it. The construction team now concentrates on clearing punch lists, finalizing as-built documentation, and turning over systems from construction to operations. That handover includes training, spare parts provisioning, and verification that warranty conditions and performance guarantees can be met once commercial operations begin.
For commissioning teams, the focus now is on data. Performance engineers will compare actual turbine output to expected power curves, adjust control parameters to optimize energy yield, and calibrate condition monitoring systems that underpin predictive maintenance strategies. The operators will also stress-test the wind farm’s cyber and physical security systems and confirm fail-safe responses across the fleet for events such as sudden grid disturbances or extreme weather.
Once in service, the project will transition to a long-term operations model anchored by an operations and maintenance base that supports technicians, spare parts logistics, and scheduled campaigns for inspection and upkeep. Early operational years typically emphasize blade and drivetrain inspections, oil sampling, gearbox and generator condition monitoring, and periodic firmware updates. The goal is to lock in stable performance, validate availability targets, and build a maintenance history that supports fleet-wide reliability.
Project leaders have framed this step as proof that large-scale offshore wind construction and commissioning can be executed safely and predictably. This project is the first offshore wind project in the Asia-Pacific region to deploy piling-free suction bucket jacket foundations at scale and first offshore wind farm globally to install 14 MW wind turbines with 115-meter-long blades – the largest of their kind in the world. All of the 66 wind turbines were installed in just 275 days.
