On the western Sichuan Plateau at an altitude of over 3000 meters, the construction of major energy projects is accelerating. The Lianghekou hybrid pumped storage power station has completed the excavation of the foundation pit for the inlet and outlet of the upper reservoir, and the excavation work for the upper reservoir has been completed. The project has officially entered the construction of the main structure, and the construction of the high-altitude super power bank has reached a critical turning point.

High altitude precision construction

The Lianghekou Hybrid Pumped Storage Power Station is the world's largest under construction hybrid pumped storage power station. It relies on the renovation and expansion of the existing Lianghekou Reservoir and is the core project of the integrated water, wind, solar and storage base in the Yalong River Basin. POWERCHINA implements precision and intelligent construction in project construction, innovates the four-dimensional quality control system for anchor cable construction, and uses the paint label method to implement visual quality control. The project builds a concrete weir flood control system, equipped with a real-time monitoring intelligent anti-seepage grouting system, meteorological warning AI safety monitoring intelligent blasting electronic fence and other digital equipment put into use on site to ensure engineering construction under complex high-altitude conditions.

Empowering new power systems

The inlet and outlet of the upper reservoir play a crucial role in water exchange and energy conversion, and the completion of this node will clear obstacles for subsequent construction. After the completion of the project, it can achieve multiple functions of peak shaving, valley filling, energy storage, and frequency regulation, smooth the fluctuation of wind and photovoltaic power output, improve the level of clean energy consumption in western Sichuan, effectively guarantee the power supply in Sichuan and Chongqing, assist in the green and low-carbon transformation of regional energy, and strengthen the local energy security barrier.Editor/Min Jing
