On 8 August, a wind turbine at the Greater Changhua 4 Wind Farm automatically tripped and ceased operation after its system detected an abnormal condition. Following this, the wind farm team observed a fire on the turbine, and the fire was extinguished shortly after. We can confirm that no personnel were injured in the incident and all relevant authorities and key stakeholders have been notified.
The team immediately implemented safety measures and isolated the turbine from the transmission system. The turbine remains shut down and isolated, while the rest of the wind farm continues to operate normally, and a safety exclusion zone has been established around the turbine as a precaution.
Offshore wind farms are designed with multiple layers of safety protection and equipment isolation mechanisms. When an individual piece of equipment detects an abnormal condition, it can be stopped and isolated immediately, preventing the incident from affecting other turbines or the wind farm's overall operation.
We will continue to investigate the cause of the incident in close collaboration with our supplier Siemens Gamesa and closely monitor the situation. An investigation plan and a subsequent repair plan have been developed. All actions will prioritize personnel and operational safety, with the utmost consideration given to ensuring no impact on the surrounding marine environment.
The root cause of this incident remains subject to further investigation. We continue to follow statutory reporting requirement and remain in close dialogue with the competent authorities and key stakeholders on the progress. Before the facts are fully confirmed, we urge all parties to avoid speculating on the cause or potential impact of the incident to ensure the accuracy of relevant information.
