In 2025, under the guidance and support of superior dispatching entities including the Changjiang Water Resources Commission of the Ministry of Water Resources, State Grid Corporation of China, and China Southern Power Grid, CYPC under China Three Gorges Corporation successfully completed flood control, drought relief water supplementation, ecological scheduling, among other tasks. The annual power generation of the world's largest clean energy corridor exceeded 300 billion kilowatt-hours for the first time, fully realizing the comprehensive benefits of this key national infrastructure.
Safeguarding the flood safety of the Yangtze River to protect livelihoods. Confronting the "strongest autumn rainfall" since 1961 in western China, the world's largest clean energy corridor broke its established operational rhythm of "pre-flood drawdown, flood-season operation, and post-flood impoundment", implementing flood control operations during the impoundment period. Notably, the Three Gorges Reservoir maintained its water level at 152 meters during drawdown for the first time, retaining approximately 3.6 billion cubic meters of floodwater with a peak flow reduction rate of 40%. This achieved "droughts without disaster, floods without damage" in the basin, making outstanding contributions to Yangtze River flood and drought management.
Demonstrating responsibility in energy supply security. CYPC continuously strengthened its core capability in integrated operation of cascade reservoirs, successfully completing multiple rounds of power supply guarantees for national major events including the September 3 Military Parade and the Fourth Plenary Session of the 20th CPC Central Committee. During the peak summer consumption period, the corridor achieved extended-period and high-load operation, generating an additional 14 billion kilowatt-hours through water conservation and achieving year-end stored energy over 34 billion kilowatt-hours, both of which reached record highs. Its role as the "ballast stone" and "pillar" in energy supply security was fully demonstrated.
Alleviating drought and replenishing water to benefit millions of households. The corridor fully leveraged its function as a strategic freshwater resource reservoir, actively supporting the Yangtze-Hanjiang River Water Diversion Project. During dry seasons, it supplemented a total of 25.2 billion cubic meters to the middle and lower reaches of the Yangtze and Hanjiang rivers. Specifically, the Three Gorges Reservoir implemented three rounds of irrigation-supporting water supplementation operations, providing approximately 7.2 billion cubic meters that effectively secured summer grain harvest water demands in the middle and lower Yangtze River basins.
Ecological scheduling yields results. The corridor conducted 13 rounds of ecological scheduling operations across three categories and two rounds of sediment reduction operations at the reservoir tail throughout the year. During ecological scheduling trials at Three Gorges Reservoir to promote natural reproduction of drifting-egg spawning fish, both the total spawning scale in Shashi section and total fry quantity in Jianli section reached historic highs, effectively advancing ecological preservation and biodiversity restoration along?the Yangtze River.
2026 marks the beginning year of the "15th Five-Year Plan". As the operator and manager of the world's largest clean energy corridor, CYPC will, building on this new starting point, faithfully fulfill the duties and missions entrusted by China Three Gorges Corporation. Specifically, we will manage these strategic national assets through lean operation to better serve the overall interests of the Party and the country, support high-quality economic and social development, and make new contributions to safeguarding the flood safety of the Yangtze River, ensuring national energy security, and comprehensively advancing Chinese path to modernization.
