How long does it take for borehole migration in pumped storage power station?

45 to 60 months. It will take 45 to 60 months from drilling to resettlement of pumped storage power station, which will set a new record in the history of pumped storage engineering construction in China. It is planned that the drilling work of pumped storage power station will last for more than two and a half months. Pumped storage power station pumps water to the upper reservoir by using electric energy at low power load, and then releases water to the lower reservoir for power generation at peak power consumption.
