Impoundment is the "ultimate test" of project construction. Facing the severe challenge of closing the gates under high water levels and high flow velocities, the PowerChina project management team invited authoritative experts to review the gate-closing plan, conducted desktop sandbox drills for emergency response plans, and used underwater 3D sonar equipment to precisely survey the gate slots and sill, comprehensively ensuring a safe and controllable gate-closing process.

Facing the complex conditions of deep water and high waves at the diversion tunnel outlet, the PowerChina project team adopted an integral one-time lifting of steel caisson structures and underwater concrete pouring technology, rapidly completing cofferdam construction and creating, ahead of schedule, dry-land construction conditions for the temporary diversion tunnel plug. This set a construction record for concrete pouring of a temporary diversion tunnel plug under complex conditions.

After the station is fully operational, it is expected to generate about 10.2 billion kilowatt-hours of electricity annually, saving 3.99 million tons of standard coal and reducing carbon emissions by about 7.37 million tons each year. This is of great significance for optimizing the energy mix, promoting coordinated regional economic and social development, and serving the national "dual carbon" strategy.
