Mr. Vu Ngoc Phan, Vice director of Hydro- Power Project Management Board No.1 - the authority on behalf of Vietnam Electricity to manage and operate the project revealed that while hydro-power reservoirs in the Central region and Highlands had become exhausted, the grid connection of the second unit of Huoi Quang project played a significant role in supplying a major power source for the national power system in this dry season. Moreover, this also marked a milestone in completing the whole project by November 2016 as planned.

The Huoi Quang project is located on the Nam Mu river, a tributary of the Da river. The headworks are located in Khoan On commune, Than Uyen district, Lai Chau province. The plant is sited in Chieng Lao commune, Muong La district, Son La province.
This is the first underground hydro power plant designed and constructed by Vietnam with 2 underground water tunnels inside the mountain, each is 4.2 km in length, 7.5 meters in diameter. The generator is installed inside the mountain.
With the capacity of 520MW, Huoi Quang Hydro-power plant can supply up to 1.9 billion kWh power for the national power system.
