Chongqing- During the sweltering weather, Chongqing's forest fire situation was severe, with different fire outbreaks in some districts and counties.
Since the summer, Chongqing's electricity situation has been bleak because of the extremely high temperature. More than 10,000 State Grid Chongqing Electric Power Company workers make sure the city's power supply is reliable and runs smoothly.
A mountain fire broke out in Jieshi Town, Banan District, recently leading to the continuous exposure of power lines to high temperatures.
That night, the State Grid Chongqing Electric Power Company activated its emergency plan and set up a rescue command. 145 courageous repair personnel were sent to the disaster areas to conduct on-site investigations and formulate emergency repair plans.
Despite the extreme heat and intense smoke brought by the wildfire and high temperature, a repair technician climbed the tower to repair the burning lines, replace the damaged insulators, and deal with the impaired wires.
Coupled with drones, video surveillance, and other methods, the open fire near the broken lines was extinguished the following day, and the fire was effectively contained.

Electricity transmission to meet Chongqing's demand
The State Grid Chongqing Electric Power Company closely monitors the national supply situation and power transmission channels to protect the electricity supply.
With the strong support of the State Grid Corporation of China, Chongqing opened northwest and northeast power transmission channels, and six regional power grids, 15 provincial power grids, and 15 direct currents (DC) were connected.
As far as 1,600 and 2,600 kilometers from Chongqing, electricity was imported from eastern Inner Mongolia and Liaoning Provinces. The electricity transmission from the China Southern Power Grid to Chongqing was made possible for the first time by utilizing the enormous power grid edges.

Likewise, the State Grid Chongqing Marketing Service Center used big data technology to ensure the safe and stable operation of the marketing system operation, maintenance, and data monitoring under high temperatures.
"We extract data every 15 minutes on the load pressure limited situation and analyze the results accurately with three special lines for supervision," said a company representative.
According to the Economic and Information Technology Commission, a power shortage is alleviated in Chongqing by working from supply and demand.
For example, power generation should be well-planned for coal storage, natural gas protection, and water storage. The potential of the city's 135 power points, such as small hydropower, local power grids, and self-provided power plants, should be explored to increase supply.
Chongqing's primary power plants stocked 3.04 million tons of coal with an increase of 22.7% year-on-year, which can meet the city's coal-fired units for about 30 days of stable and complete hair needs.
