The province's meteorological center said many parts of Hunan Province could see minimum temperatures plunge to below zero degrees Celsius starting Jan. 20, which could easily lead to ice-covered power lines in mountainous areas, posing a challenge to the normal operation of the power grid.

In response to the cold wave, the production and control centers of the company have been running 24 hours a day, and teams have been established to deal with ice on the power grid.

According to statistics, the company has sent 5,973 personnel and 1,925 vehicles to carry out inspections and tests on 1,786 power lines and 417 transformer substations. Emergency repair teams and equipment have also been set up in key areas.
