Ensuring reliable power supply during peak summer demand is a "tough battle" that the company faces every year. On June 13, the company held its third meeting of the 2025 Peak Summer Power Supply and Safety Committee, where key tasks for power supply assurance, safe production, and flood prevention were planned and deployed. Then, on June 18, the company conducted a joint anti-accident drill for the 2025 Peak Summer period and large-scale power outage scenarios, thoroughly testing the company’s emergency response system and capabilities. Throughout the peak summer period, all units within the company remained united in managing the grid, strengthened collaboration between government and enterprises, firmly assigned responsibilities, meticulously organized operations, and refined measures—effectively addressing this year’s unprecedented challenges, including the longest-lasting high-temperature load, below-average water inflows in major river basins, frequent severe rainstorms and flooding disasters, and concentrated power demands tied to major events. As a result, the company successfully safeguarded both the critical safety line and the essential electricity supply needed to meet public needs.

From June to August, China experienced its highest average temperatures on record, making it the hottest summer since temperature records began. Driven by economic growth and prolonged, widespread heatwaves, electricity demand across all sectors surged significantly. Cooling loads—particularly from air conditioners—spurred a continuous rise in overall power consumption.

On July 4, the nation’s peak electricity demand reached 1.465 billion kilowatts, while the company’s operational area saw a load of 1.196 billion kilowatts. These figures continued to rise from August 4 to 6, peaking on August 20 at 1.235 billion kilowatts—up by 55 million kilowatts compared to last summer’s previous high of 1.180 billion kilowatts.

Jiangsu's power grid saw its peak electricity demand exceed 156 million kilowatts, Shandong's grid experienced its load reach a record high eight times, and Henan's grid recorded a 12.4% increase in peak demand compared to last year's previous record—highlighting the ongoing challenges of meeting soaring summer electricity needs. According to data from the National Electric Power Dispatch and Control Center, during this year’s peak-demand period, the company’s operational areas witnessed electricity loads hit new highs six times, while 18 provincial grids across six regional power systems collectively set 81 all-time records. To effectively manage these summer peak demands, the company had anticipated the situation well in advance and made thorough preparations.

Various power sources have been ramped up to ensure a stable supply, providing the "grain and fodder" needed to secure electricity availability. As of the end of July, the nation’s total installed power generation capacity reached 3.67 billion kilowatts. The company has proactively enhanced grid connection services for power sources, leveraging the inter-ministerial coordination mechanism for coal, electricity, oil, gas, and transportation. Working closely with power-generation enterprises, we’re strengthening integrated management of primary energy resources while also advancing the application of advanced technologies like renewable energy forecasting.
