The Chongqing power grid set a new load record on July 14. At 17:11, unified dispatch load hit 30.67 GW, exceeding the previous maximum of 30.28 GW by 0.39 GW.
This surge is closely linked to high temperatures. Since late June, temperatures in Chongqing have been rising, and on July 14, the Chongqing Meteorological Observatory issued its first "red high-temperature warning," leading to widespread use of air conditioning and cooling devices.
State Grid Chongqing Electric Power Company stated it is closely monitoring weather and load changes, coordinating load forecasting, grid dispatching, and equipment maintenance. In dispatch operations, it optimized generation plans, utilized adjustable power sources, purchased spot power interprovincially as needed, and adjusted summer operation modes to strengthen monitoring and control.
Eleven key summer projects were commissioned on schedule to boost power supply capacity. Power plants were urged to maintain their units, ensuring all available capacity is connected and generating.
For external power purchases, Chongqing secured medium- and long-term interprovincial contracts before summer, serving as a ballast for supply. Through cross-unit and cross-professional consultation mechanisms, daily discussions, weekly coordination, and monthly planning are held to ensure transmission channels from other regions operate at full capacity during summer peak hours. This year, Chongqing's transacted maximum external power reached 11.87 GW. The "Xinjiang Power to Chongqing" project's current maximum transmission is 6 GW, accounting for roughly one-fifth of the grid's unified peak load.
Equipment maintenance was also strengthened. Before summer, over 6,000 grid equipment overhauls were completed; core substations and transmission lines from power plants received targeted protection. Three mobile substations and 29 medium-voltage generator vehicles are on standby. Currently, State Grid Chongqing Electric Power deploys an average of 4,700 professional personnel and 1,200 vehicle trips daily, conducting over 1,200 special patrols and over 1,000 infrared temperature checks, with 76 substations staffed and 165 grid-based stations on duty.
