Laos is taking a major step to strengthen its position as a renewable energy hub in Southeast Asia. The country’s state electricity company has signed an agreement with a South Korean private firm to build a 100-megawatt (MW) solar power project in the northern province of Oudomxay, near the Namhin Reservoir in Xay district. The project is part of Laos’s wider plan to diversify its energy sources and enhance its reputation as the “Battery of Southeast Asia.”
Currently, the project is undergoing feasibility studies, with construction expected to start in 2027. Once completed, the solar plant will produce around 160 gigawatt-hours of electricity each year, enough to power about 100,000 homes. The facility will cover roughly 150 hectares, making it one of the largest solar developments in the region.
A key aim of this project is to increase energy exports. A significant portion of the electricity generated is planned for export to Vietnam. By sending clean energy to neighboring countries, Laos hopes to earn valuable revenue while helping the region meet its renewable energy goals. This approach also allows Laos to make the most of its natural resources and strengthen cross-border energy trade within ASEAN.
The solar project will also play an important role domestically. Laos has traditionally relied heavily on hydropower, but seasonal changes can affect water availability and reduce electricity production. By adding solar energy, the country can maintain a more stable power supply, especially during the dry season. This will reduce the need to import expensive electricity and help keep energy prices stable for local consumers.
This development comes after other significant achievements in the region. Laos recently launched a 1,000 MW solar plant that exports electricity to China. The country has also built infrastructure to support cross-border energy trade, such as the Laos-China 500 kV transmission line. The new agreement with the South Korean company adds to these efforts and highlights Laos’s growing role in the transition to green energy.
Through projects like this, Laos is showing that it can balance domestic energy needs with international trade ambitions. By investing in solar power and forming international partnerships, the country aims to secure its energy future while contributing to the region’s clean energy targets. The Oudomxay solar project is an important step toward making Laos a key player in Southeast Asia’s renewable energy landscape.
