The first unit will be commissioned by the end of March 2023, and all units will be put into commercial operation by the end of December 2023. After completion, ZhenAn will be used for peak regulation, frequency regulation, and as synchronous condenser. In addition, it will serve as emergency standby reserve and black-start capacity for the Shaanxi power grid.
