The Monsoon Wind Power Project achieved commercial operation, becoming the first cross-border renewable energy project in Asia. The 600 MW project delivers electricity from southern Lao PDR into Vietnam, contributing to regional power supply and grid integration.
Located in the Dak Cheung District of Sekong Province and the Sanxay District of Attapeu Province, the wind farm consists of 133 turbines. Electricity generated is transmitted through four 115 kV substations, stepped up to 500 kV at the project substation, and carried along a 27-kilometre high-voltage line to the Lao–Vietnam border, where it connects to Vietnam’s 500 kV transmission system before continuing 44 kilometres to EVN’s Thanh My substation.
The project was initiated by Impact Electrons Siam and is developed and operated by Monsoon Wind Power Company, a Lao-incorporated company. Shareholders include Impact Electrons Siam, ACEN of the Philippines, BCPG and STP\&I of Thailand, Mitsubishi Corporation and its subsidiary Diamond Generating Asia of Japan, and SMP Consultation Sole Company of Lao PDR.
Financing was arranged by a group of regional and international lenders led by the Asian Development Bank. Other institutions include the Asian Infrastructure Investment Bank, Japan International Cooperation Agency, Export–Import Bank of Thailand, Hong Kong Mortgage Corporation, Sumitomo Mitsui Banking Corporation, Kasikornbank, and Siam Commercial Bank. Construction was carried out by PowerChina, with turbines supplied by Envision Energy.
