Lianghekou Dam, Embankment dam and hydroelectric station in Yajiang County, Sichuan, China
Lianghekou Dam is a hydroelectric facility at the convergence of three rivers in a remote mountain area of Sichuan Province. The structure holds back a massive water reservoir that feeds turbines for power generation.
Planning studies for the site took place during the 2000s before construction commenced in 2014. The facility reached full operational status in the early 2020s.
The development of Lianghekou Dam required the relocation of 4,900 residents, demonstrating the scale of social changes brought by large infrastructure projects in China.
The site sits at high altitude in a remote mountain region, so reaching it takes time and the air is thinner. Most visits require special permission and organized access arrangements.
A pumped-storage facility works alongside the main dam, storing excess energy when demand is low and releasing it when needed. This system allows for more flexible power supply to surrounding areas.
