China's Tiantai pumped storage power station has been fully commissioned and is now in commercial operation. As the country's new benchmark for large-capacity pumped storage units, this key national energy project features advanced hydropower technology and high operating efficiency. The station effectively provides stable peak-load power for residential and industrial users, enhances grid stability and improves the reliability of the power supply. It also helps reduce fossil fuel consumption and carbon emissions, supporting China's clean energy transition and low-carbon development.
