Warang Pumped Storage Power Station is located in Guinan County, Hainan Tibetan Autonomous Prefecture, Qinghai Province. Construction officially started in August 2023, with a total investment of 15.94 billion yuan and a total installed capacity of 2.8 million kilowatts. The overall construction period of the project is about 8 years. It is planned to achieve power generation by the first unit in September 2030 and to be fully connected to the grid and put into operation in December 2031. It is estimated that after the power station is put into operation, it can replace coal consumption by 1.82 million tons and reduce carbon dioxide emissions by 4.55 million tons.
The main project of the power station covers core facilities such as upper reservoir, lower reservoir water inlet and outlet, water transmission system, underground factory building and ground switch station. After being put into operation, it can fully play important roles in energy storage, peak regulation, valley filling, frequency regulation, phase regulation and grid emergency backup, providing guarantee for the large-scale consumption of new energy sources such as regional wind power and photovoltaics.

The ventilation and safety tunnel that was handed over this time is a key pilot project in the construction of the power station. During the construction process, it faced unfavorable geological problems such as water inflow, fault fracture zones, and weak interlayers. It was technically difficult and had high safety prevention and control risks. The construction team relied on advanced geological forecasting technology throughout the process to solve the problems one by one and successfully completed the tunnel handover. (over)
