Recently, staff members have carried out maintenance of offshore wind turbines and step-up substations at two offshore wind farms, so as to ensure a stable and safe power supply during the incoming high temperature period.

From January to May this year, the total power generation capacity of the two wind farms reached 880 million kWh, with an accumulated power output of 10.26 billion kWh since their operation in December 2021. (Photo by Xu Congjun/Xinhua)
