On October 28, the groundbreaking ceremony for the main works of the Shaanxi Shanyang Pumped Storage Power Station, surveyed and designed by Northwest Institute, was held, marking that the main powerhouse of the power station has officially entered the stage of full-scale construction.

Prior to this, the power station construction had already celebrated the successful breakthrough of the ventilation and safety tunnel on October 26. The tunnel has a total length of 901.63 meters, a clear cross-section of 7.5 m × 8 m (width × height), and a maximum longitudinal slope of 9.46%. The ventilation and safety tunnel is not only a key passage for air intake and safety evacuation for the underground cavern group, but also the only access for excavation of the first level of the main powerhouse. The tunnel passes through areas with complex geological conditions; the surrounding rock is predominantly Class III, with local densely fractured zones and fault zones being Class IV surrounding rock, which has poor stability, making construction difficult and safety risks high.

Facing numerous challenges, the design project department, together with the owner, supervision, construction and other participating units, carried out in-depth site surveys, made scientific assessments and worked together to overcome difficulties. After 191 days of intensive work, they completed the breakthrough target ahead of schedule, laying a solid foundation for the commencement of the main works.

As a key implementation project of the 14th Five-Year Plan in the national medium- and long-term development plan for pumped storage, the Shanyang Pumped Storage Power Station is located in Shanyang County, Shangluo City, with an installed capacity of 1.2 million kilowatts and a designed annual power generation of 1.511 billion kilowatt-hours. After completion, the power station will undertake tasks such as peak shaving, valley filling, energy storage, frequency regulation, phase modulation and emergency accident reserve for the Shaanxi power grid, increase the proportion of new energy power sources in Shaanxi Province, and help build a new-type power system in Shaanxi Province. It can save about 744,300 tons of standard coal per year, and is of great significance to achieving the "dual carbon" strategic goals and building a new-type power system with new energy as the main body.
