The Sê San 4 Hydropower Plant Expansion Project aims to supply clean electricity from renewable energy sources to the national power system, contributing to energy security and meeting electricity demand for socio-economic development.

The project will also provide additional reserve capacity, enhance the system’s ability to mobilize generation during peak hours, and increase operational flexibility as the share of renewable energy sources such as wind and solar power continues to rise.

In addition, the project will utilize excess water discharged annually during the flood season by the existing Sê San 4 Hydropower Plant for power generation. This will help improve operating conditions, enhance the reliability and safety of the power system, while reducing fossil fuel consumption and CO₂ emissions./.
