Laos has formalized a build-operate-transfer (BOT) concession for the 80-megawatt Xekaman 4 Hydropower Project in Sekong province, with all electricity generated designated for export to Vietnam.
The agreement, signed on 15 March, involves the Viet-Laos Electricity Joint Stock Company and Vietnam’s Xekaman 4 Electric Power Company. Xekaman 4 is the latest development in the Xekaman cascade, which includes Xekaman 1, 2, and 3, collectively strengthening Laos’ hydropower output along the Sekong River.
Officials said the new plant will employ modern turbines and transmission systems to ensure efficient power delivery to Vietnam while supporting Laos’ goal of expanding renewable energy production.
Hydropower remains the backbone of Laos’ energy sector, accounting for most of the country’s 12.4 GW installed capacity in 2025. Investments in renewable energy are also rising, including the 1,000 MW Oudomxay solar plant and the Monsoon Wind Power Project in southern Laos, which directly exports electricity to Vietnam.
