Asia’s first cross-border renewable power project fully connected to grid

Updated: September 01, 2025

The first cross-border renewable energy project in Asia, a 600-megawatt wind power plant in Laos built by Power Construction Corporation of China (PowerChina), has been fully connected to the grid and entered commercial operation. The project also provides solid support for Lao’s vision of becoming the “Battery of Southeast Asia”.

Located in Sekong and Attapeu Provinces, the Monsoon Wind Power Project is Laos’s first wind power development and a landmark outcome of China-Laos green energy cooperation under the Belt and Road Initiative. It consists of 133 wind turbines of 4.5 megawatt each, a booster station and a 500-kilovolt transmission line. The plant is expected to generate about 1.72 billion kilowatt-hours of electricity annually.

The project was built in four sections, with the first two entering commercial operation in July this year before the full-capacity connection this month.

Electricity from the project is transmitted through a 500-kV substation and transmission line across the Laos-Vietnam border to connect with Vietnam’s grid, helping ease power shortages in central Vietnam, making it the first cross-border renewable energy project in Asia.

The facility is projected to reduce carbon emissions by 35 million tons over its lifetime and contribute to local economic and social development.
