On June 21, the groundbreaking ceremony for the civil works, electromechanical and metal structure equipment installation project of the water conveyance and power generation system of the Huanglong Pumped Storage Power Station, undertaken by Sinohydro Bureau 14 Co., Ltd., was held in Tianshui City, Gansu Province, marking the project's official entry into the substantive construction phase.

The Huanglong Pumped Storage Power Station is one of the key implementation projects of Gansu Province's 14th Five-Year Plan for pumped storage in the Medium- and Long-Term Development Plan for Pumped Storage (2021-2035), and is also the pumped storage power station with the largest installed capacity under construction in Gansu Province.

The project has a total installed capacity of 2,100 MW, with a rated head of 640 meters, and is equipped with six 350 MW reversible units. The station is connected to the grid via a 750 kV first-level voltage, with two outgoing circuits. Its hub structures adopt a layout of "five dams, four reservoirs, three tunnels and six units," covering key facilities such as the upper reservoir, water conveyance system, underground powerhouse and switch station, and lower reservoir.

Upon completion, the project will serve the Gansu power grid, playing roles in peak shaving, valley filling and energy storage, undertaking tasks such as frequency regulation, phase modulation and emergency accident reserve, smoothing fluctuations in system power output, improving the absorption capacity of new energy, further enhancing the quality of grid power supply, maintaining the safe, stable and economical operation of the power grid, promoting energy structure adjustment, accelerating the construction of a clean, low-carbon, safe and efficient modern energy system and a new power system with new energy as the main body, and helping to achieve the "dual carbon" goals.
