The Monsoon Wind Power Project, a 600MW wind farm in Laos, has officially commenced commercial operations.
The project, spearheaded by Impact Electrons Siam (IES), commenced operations on 22 August 2025 and is touted as Asia’s first cross-border renewable energy initiative, transmitting power from Laos to Vietnam.

The project’s 133 turbines are spread across the Dak Cheung District of Sekong Province and the Sanxay District of Attapeu Province in Laos.
The generated energy is transmitted through a network of substations and high-voltage lines, culminating in a connection to Vietnam’s national grid.
The energy from the Monsoon Wind Power Project is distributed via a 27km high-voltage transmission line to the Laos–Vietnam border, where it integrates with Vietnam’s 500kV system.
The line then extends an additional 44km to state-owned EVN’s Thanh My substation in Vietnam.
