Strategic Insights

— 1 min read

The Monsoon Wind Power Project, a 600MW wind farm in Laos, has commenced commercial operations on August 22, 2025, marking Asia's first cross-border renewable energy initiative. The project, spearheaded by Impact Electrons Siam (IES), transmits power from Laos to Vietnam through a network of substations and high-voltage lines, integrating with Vietnam's 500kV system. The initiative aims to demonstrate how ASEAN countries can work together for a cleaner, more sustainable future. The project's 133 turbines are spread across the Dak Cheung District of Sekong Province and the Sanxay District of Attapeu Province in Laos, generating energy that is distributed via a 71km high-voltage transmission line to Vietnam.
