On Aug. 31, the Shuangjiangkou Hydropower Station on the Dadu River, home to the world's highest dam, successfully achieved its Phase I goal of bringing all three generating units into full operation, providing robust new support for energy security amid high temperatures during the peak summer power demand period.

The Shuangjiangkou Hydropower Station on the Dadu River, home to the world's tallest dam, has achieved the goal of fully commissioning its first-phase generating units.

As a key national energy project, the Shuangjiangkou Hydropower Station features a 315-meter-high dam, the tallest in the world today. The station has a total installed capacity of 2 million kilowatts and is equipped with four Francis turbine-generator units, each with a capacity of 500,000 kilowatts, generating an average annual output of approximately 7.7 billion kilowatt-hours. With a total reservoir storage capacity of 2.9 billion cubic meters, the facility not only significantly enhances comprehensive water resource utilization efficiency across the entire Dadu River basin but also generates an additional 6.6 billion kilowatt-hours of electricity annually for downstream cascade hydropower stations. It serves as a pivotal regulating reservoir and leading power station in the upper reaches of the Dadu River, integrating flood control, power generation, and water resource allocation functions.

Since the first unit was commissioned in June this year, the station has actively shouldered the responsibility of ensuring energy supply for the Chengdu-Chongqing Economic Circle. Faced with surging social electricity demand driven by scorching weather, the station accelerated the commissioning of its Phase I units, efficiently completing their sequential launch within two months. To date, it has delivered a cumulative 500 million kilowatt-hours of clean hydropower, solidifying the foundation for summer power security in Sichuan Province and the Chengdu-Chongqing Economic Circle.
