On July 12, 2022, the groundbreaking ceremony for the excavation of Pingdong for the Qinshui Pumped Storage Power Station Project in Jincheng City, Shanxi Province was held in Xipo Village, Longgang Town, Qinshui County.

Qinshui Pumped Storage Power Station Project

According to reports, the planned total installed capacity of the Huaneng Qinshui pumped storage power station project is 1,200 megawatts, and the project investment is about 7.784 billion yuan. The project is mainly composed of upper and lower reservoirs, underground water transmission and power generation systems and other buildings. The project strives to complete all approvals in December 2022 and start construction in the second half of 2023 to ensure that the units are connected to the grid for power generation by 2030.

In the future, after the project is put into operation, it will undertake the tasks of peak regulation, valley filling, frequency regulation, phase regulation black start and emergency backup of the southern Shanxi power grid, which can effectively promote the consumption of new energy, adjust the energy structure of Shanxi power grid, and improve the economical operation of the power grid. It can save 125,000 tons of standard coal, 2,500 tons of sulfur dioxide and 290,000 tons of carbon dioxide every year.

The main purpose of the excavation in the flat tunnel is to find out the lithology of the strata and the distribution of unfavorable geological bodies along the water transmission line, the weathering and unloading characteristics of the rock mass along the line, the development characteristics of geological bodies such as fissures, faults and folds, and the distribution characteristics of groundwater, etc. Smooth progress to provide detailed geological data. It is an important survey method to study the feasibility of underground workshops, an important control line in the early construction period, and a sign of an important construction node entering the feasibility study stage in advance.

The Huaneng Qinshui Pumped Storage Power Station project is the first pumped storage project in Jincheng City to be excavated in Pingdong. Jincheng City has made new breakthroughs in the construction of two integrated demonstration bases of "source network load storage" and "wind-solar fire storage", marking a solid step towards the construction of a new power system dominated by new energy.
