1 Project Overview Baoquan pumped storage power station is located in Hui County, Henan Province, the thin wall Township 2 km upstream of the Valley on the river, from Xinxiang and Zhengzhou, respectively 45km and 80km. The power station is a pure pumped storage power station, with one hole, two machines, and four single-stage reversible pump turbines installed with a installed capacity of 1200MW. The upper reservoir of the power station is located in Donggou within the eastern side of Baoquan Village. The dam is a concrete faced rockfill dam. The lower reservoir is constructed by strengthening and consolidating the completed Baoquan Reservoir. It is located on the Yuhe River and the dam is masonry Stone gravity dam. The water delivery system is connected to the upper and lower reservoirs, and is composed of an upper inlet and an outlet, two primary diversion holes, four diversion branch holes, two tail tunnels and a lower inlet and outlet. The two main diversion tunnels are divided into 4 branch holes at 133.5m upstream of the center line of the unit, each branch pipe adopts “BU”
