At 22:35 on December 20th, the 24-hour trial operation of the 500kV switchyard of the Changlongshan Pumped Storage Power Station, which is the key project in Zhejiang’s "13th Five-Year Plan" period, was successfully completed, marking the complete success of the 500kV switchyard’s energization. At the same time, it is a solid step towards the commissioning of units and synchronization. The commissioning and start-up tests of the power station’s 500 kV system were in the charge of E.Energy.

After the Changlongshan Pumped-storage Power Station is put into service, clean electricity will be delivered to the grid during the daytime peak power consumption period; during the night power consumption trough period, the surplus electricity will be stored for the daytime load peak period to reduce the grid load peak-valley difference. This is equivalent to installing a giant power bank in Zhejiang Power Grid, which greatly eases the peak-to-valley difference of the power grid.
