The Monsoon Wind Power Project, Laos’ first wind farm and the largest onshore wind installation in Southeast Asia, is set to begin full operations by late August or early September 2025. Sekong Province’s Deputy Governor, Khanti Seelavongsa, confirmed the timeline during a local council meeting. Currently running at 300MW, the project will soon scale up to its full 600MW capacity. Spread across 70,800 hectares in Sekong’s Dak Cheung district and Attapeu’s Sanxay district, the USD 950 million wind farm comprises 133 turbines, each producing 4.51MW.
The project marks ASEAN’s first cross-border wind initiative, transmitting power via a 65-km, 500-kV line to Vietnam, supported by a 25-year power purchase agreement with Vietnam Electricity (EVN). Initial plans began in 2011, with feasibility studies identifying optimal locations in 2015. Construction started in April 2023, and all turbines were installed by May 2025. The wind farm, developed with participation from ACEN Renewables International and Mitsubishi Corporation, complements Sekong’s existing hydropower network, which includes the Nam Emoun and Houay La Ngae dams.
