The world's largest clean energy corridor maintained strong operational performance in the first quarter of this year, reinforcing water security, navigation safety, energy supply, and ecological protection along the Yangtze River. According to an announcement on the evening of April 15 by the China Three Gorges Corporation, the corridor has played a vital role in safeguarding regional resources.
In terms of water replenishment scheduling, the corporation implemented dynamic optimization measures based on water inflow, electricity load demand, and downstream water usage needs. By the end of the first quarter, the cascade reservoirs had supplied over 20.3 billion cubic meters of water downstream during the current dry season. This volume is equivalent to approximately 163 times the water capacity of Wuhan's East Lake.
Navigation safety was also ensured, with the Three Gorges ship locks operating safely for 2,259 lock cycles during the quarter, facilitating freight volume of 35.47 million tons. The Three Gorges ship lift safely completed 869 lifts, transporting more than 100,000 passengers, 875 vessels, and 430,000 tons of cargo.
On the energy front, the clean energy corridor generated over 61.8 billion kilowatt-hours of electricity in the first quarter, representing a 7.19% year-on-year increase. This output highlights the corridor's contribution to stable power supply.
Ecologically, the Wudongde and Baihetan hydropower stations conducted three ecological scheduling tests aimed at supporting fish species that lay adhesive sinking eggs. By adjusting water discharge rates and temperature, these tests created favorable hydraulic conditions for the natural reproduction of fish in the Yangtze River.
The world's largest clean energy corridor comprises six major hydropower stations—Wudongde, Baihetan, Xiluodu, Xiangjiaba, Three Gorges, and Gezhouba—constructed and operated by China Three Gorges Corporation along the main stream of the Yangtze River. With a total installed capacity of 71,695 megawatts spanning 1,800 kilometers, the corridor generates approximately 300 billion kilowatt-hours of green electricity annually. This output saves about 90.45 million tons of standard coal and reduces carbon dioxide emissions by roughly 248 million tons each year.
