Truong Son Wind Power Project info by Hobo Maps - Go to Wind Power Projects Page - - - HOME
The Truong Son Wind Power project is located on the Truong Son mountain range near Lak Sao town in Khamkeut district, Bolikhamxay Province of Lao PDR. The project Plant Office is located at coordinates 18°18'49.9"N 105°06'07.5"E (18.313861, 105.102083) as seen below.
Also know as Xiuchin (Xeuchin) Wind Power Project in Chinese language publications.

We're not able to give precise location coordinates for the various wind towers as they are spread over several ridges but assume they would not be far from Lak Sao town and the Vietnam Border checkpoint at Nam Phao.
The 600 MW project is being developed in two phases. Truong Son Wind Project Phase 1 with 250 MW is completed with capital imvestment of over US$ 371 million. Project 2 with 350 MW is soon planned to be under construction in 2026 with capital imvestment of around US$ 556 million. Both Phases are planned to operate for 25 years and have Build, Operate Transfer (BOT) concession agreements with Government of Lao PDR for the same periods.
Viet Lao Energy Investment and Power Corporation (VLE) was developer and investor of Phase 1 and may be the owner. Phu Xuan Construction and Trading Co. Ltd. (PXC) was the general contractor for Phase 1.

Not sure how many towers with turbines for Phase 1 have been installed but two sources report the towers to be 120 meters high with wing spans of 182 meters. Not sure how long the blades are but likely around 90 meters.
Phase 1 of the Truong Son Wind Power project has an installed capacity of 250 MW from turbines (unsure how many) of 6.25 MW and 8 MW capacity each manufactured by Goldwind. The project has an expected electricity output of approximately 715 GWh per year. The project's estimated operational lifespan could extend up to 50 years although the original consignment period with Lao PDR is only 25 years.
The towers are located at elevations between 1,400 meters and 2,000 meters above sea level.
Construction of the 250 MW Phase 1 began in April 2024 and was completed in just 15 months with an official commercial operating date (COD) of September 26, 2025.

No info so far about detailed terms for Power Purchase Agreements with Electricity of Vietnam (EVN) but previously the project investor sent a proposal to sell electricity to EVN at the prevailing ceiling price for importing wind power electricity from Laos to Vietnam. The standard ceiling rate rate after 1 January 2026 for wind power imported into Vietnam is US$ .064 cents per unit (kWh).
On September 6, 2025, Viet Lao Energy and Investment Joint Stock Company (VLE) – the Investor of Truong Son Wind Power Plant Cluster together with the Power Transmission Corporation of Vietnam and related parties completed synchronous electrification of the transmission line.
The Truong Son 220 kV substation and Truong Son–Do Luong 220 kV transmission line (75 km in length in Vietnam) was invested by VLE Company. This is the first transmission grid project to generate electricity for electricity import from Laos to Vietnam invested by the private sector instead of by EVN. All prior importing transmission lines inside Vietnam were financed and managed by state-owned EVN. The total transmission line distance is reported to be 81 km.
The power line starts from the 220 kV Do Luong substation and ends at a connection point located in Vietnamese territory just 100 meters from the Vietnam-Laos border, in the area of the Thanh Thuy Border Gate Station (Thanh Thuy commune, Thanh Chuong district).
Phase 2 of the Truong Son Wind Power project with planned capacity of 350 MW was set to begin construction in 2025 and be completed in late 2026 or 2027. Should be an easy activation since Phase 2 will share the same transmission facilities already constructed for Phase 1.
On 16 December 2025, Vietnam Technology Co., Ltd. (VTECH), acting as the main construction contractor, successfully energized the 220 kV TS2 Substation which is a pivotal component of the Phase 2 Project.
