On August 16 at 12:00 a.m., the scorching sun pushed ground temperatures to an alarming 50 to 60 degrees Celsius. Amid this relentless heat, within the confines of the 220kV University Town Substation of the State Grid Chongqing Electric Power Company, a group of young employees, clad in yellow safety helmets and red vests marked for power transformation center operations and inspections, diligently scrutinized the equipment.

The substation stood exposed to the relentless heatwave, offering no respite from the blazing sun. Amidst the sizzling currents, the whirring of fans, and the constant chorus of cicadas, Wei Jiajia, a vigilant watchkeeper of the centralized control team, offered insight, “Due to Chongqing’s prolonged high temperatures, the municipal power demand has peaked, resulting in increased stress on the substation equipment. Consequently, inspections have become more frequent and extended, ensuring the safe and stable provision of electricity and the reliable operation of the power grid.” At that moment, Wei had just completed an inspection, his work attire drenched in sweat.
