From October 1 to 8, 2025, as the nation celebrated the combined National Day and Mid-Autumn Festival holiday, the world's largest clean energy corridor generated a cumulative 10.3 TWh of electricity. This figure represents an increase of 5.85 TWh year-on-year, setting a new record for the same period in history. During this holiday, the corridor delivered a stable and reliable supply of clean electric energy to power-receiving regions including Central and East China, as well as Sichuan, Chongqing, Yunnan, and Guangdong, fully demonstrating its role as a "cornerstone" and "mainstay" in securing the national energy supply—a true testament to its status as a strategic national asset.

Coordinated efforts safeguard the safe and stable operation of the power grid. Under the guidance of dispatching authorities including the Changjiang Water Resources Commission of the Ministry of Water Resources, the State Grid and the China Southern Power Grid, China Yangtze Power Co., Ltd. (CYPC) (a subsidiary of China Three Gorges Corporation (CTG)) have engaged in the refined operational management of the world's largest clean energy corridor. By tapping into the full potential of joint operation capabilities of the cascade hydropower plants, the company successfully achieved the remarkable feat of "generating electricity six times from a single drop of water". To date, the green corridor has generated a cumulative total of over 4,000 TWh of electricity. This is equivalent to saving 1.2 billion tons of standard coal and reducing carbon dioxide emissions by nearly 3.3 billion tons, marking a vital contribution to ensuring national energy security and promoting the green and low-carbon energy transition.

Governance is promoted with intelligence to ensure both flood control and power supply. CYPC is accelerating the development of its digital twin systems and the "Three Lines of Defense" framework. By continuously enhancing hydrological and meteorological forecasting for precise, integrated operation of reservoirs, the company is contributing the "CTG strength" to water governance and management in the new era. On October 1, 2025, following its successful management of the year's largest peak flood event with a peak discharge of 42,500 m3/s on September 20, the Three Gorges Reservoir encountered another flood peak of 35,000 m3/s. Acting on prior directives from the Changjiang Water Resources Commission (CWRC), the reservoir's outflow was increased in advance to 28,400 m3/s to further lower its water level, effectively ensuring the safety and stability of the Yangtze River.

Strategic water impoundment is practiced to solidify the foundation for power supply of the upcoming winter and spring seasons. CYPC is closely monitoring hydrological conditions and changes in energy supply and demand, and optimizing the operational management of its cascade hydropower plants. Under the unified control of CWRC, it is making every effort to secure electricity supply for the upcoming winter and spring seasons. As of 24:00 on October 8, 2025, the available water storage in the cascade reservoirs reached approximately 36 billion m3, an increase of 8 billion m3 year-on-year. During the impoundment period, the dams, power plants, and their associated equipment and facilities have all been operating in excellent condition, storing precious water resources for water replenishment during the upcoming dry season and to meet peak winter demand.

It is reported that the world's largest clean energy corridor, formed by six cascaded hydropower plants on the main stream of the Yangtze River—Wudongde, Baihetan, Xiluodu, Xiangjiaba, Three Gorges, and Gezhouba HPPs—has a total installed capacity of 71.695 GW. With an average annual power generation of approximately 300 TWh, it can save over 90 million tons of standard coal and reduce carbon dioxide emissions by over 240 million tons each year. This carbon reduction benefit is equivalent to planting a 658,000-hectare broadleaf forest—an area capable of covering three-quarters of Wuhan—providing a powerful impetus for the green development of the Yangtze River Economic Belt.
