The Dadu River Eagle Rock Second Hydropower Station successfully impounded water, achieving key milestone objectives.

Reporter today (23rd) learned from the State Energy Group that the Daduhe River Dajiang diversion at the Daduhé Eagle Rock Second Hydropower Station has been successfully completed, smoothly achieving key milestone targets. Dajiang diversion is a milestone control step in hydropower project construction, marking the project’s official transition from auxiliary works to main construction, and providing dry-land conditions with no water for subsequent concrete placement of the main structure. The cofferdam for this station’s diversion has a maximum fill volume of about 650,000 cubic meters, and uses a concrete seepage-proof wall with a thickness of 1 meter and a maximum depth of 91 meters to cope with the complex geological conditions of a 60- to 90-meter-thick cover layer in the riverbed. The Eagle Rock Second Hydropower Station is planned to put its first generating unit into operation in 2029. With a total installed capacity of 420 megawatts, it has a designed annual power generation of 1.838 billion kilowatt-hours. Each year, it can save more than 500,000 tons of standard coal and reduce CO2 emissions by more than 1.5 million tons, which will significantly strengthen the region’s power supply security and assurance capacity.
