The World's Highest Head Pumped Storage Power Station Welcomes Critical Progress - The First Unit Of Tiantai Power Station Successfully Lifts The Inlet Ball Valve

On March 2nd at 13:00, Zhejiang Tiantai Pumped Storage Power Station successfully completed the lifting of the first (No. 1) unit inlet ball valve, marking the project's official entry into the critical sprint stage of mechanical and electrical installation. This power station is the world's under construction pumped storage power station with the highest rated head (724 meters), and has important demonstration significance.

The inlet ball valve lifted this time is one of the core components of the unit, weighing 142 tons and measuring 6.7 meters (length) x 3.12 meters (width) x 4.04 meters (height). Its installation quality directly affects the operating efficiency and safety stability of the unit. To ensure the smooth progress of lifting, the project team has developed a detailed construction plan and emergency response plan in advance, strictly followed the operating procedures, monitored key parameters in real time, and ensured the safety, accuracy, and efficiency of the entire operation process. After 1 hour of precise operation, the inlet ball valve was successfully positioned.

The Tiantai Pumped Storage Power Station is located in Tiantai County, Taizhou City, Zhejiang Province. It is one of the key projects of the 14th Five Year Plan and a major energy construction project in Zhejiang Province. The total installed capacity of the power station reaches 1.7 million kilowatts, with the highest rated power generation head in China, and features the largest single unit capacity, deepest burial depth, and longest shaft system.

The successful hoisting of the inlet ball valve this time is an important milestone in the project construction, which not only demonstrates the efficient execution of the project team, but also accumulates valuable experience for the subsequent installation of the unit. Next, the Tiantai Mechanical and Electrical Installation Project Department stated that they will continue to uphold a work attitude of striving for excellence, steadily advance the subsequent installation process, and ensure the smooth commissioning and power generation of the first unit by 2025.
