Groundbreaking Ceremony Held for Dong Phu Yen Pumped Storage Project in Son La
A groundbreaking ceremony for the Dong Phu Yen pumped storage project was held in Vietnam’s Son La province on November 14, 2026. The 1,200 MW project has a planned investment of nearly VND 28 trillion and will be built in two phases. Construction of the first phase is scheduled to begin in the fourth quarter of 2027.
On November 14, 2026, the Son La provincial government held a groundbreaking ceremony for the Dong Phu Yen pumped storage project in Mường Bang commune with Xuan Thien Group Joint Stock Company and Xuan Thien Ninh Binh Co., Ltd. The latter is the project investor, and the project spans Mường Bang and Mường Cơi communes. The Son La provincial government approved the project’s investment policy on August 30, 2026.

The project has a total installed capacity of 1,200 MW across four generating units and involves an investment of nearly VND 28 trillion. It includes upper and lower reservoirs, each with a usable capacity of 6.5 million cubic meters, and a transmission line nearly 10 kilometers long connecting to the 500 kV grid. Once completed, the project is expected to generate about 1.5 billion kWh of electricity annually and provide backup and regulation for the power system.
The project will be implemented in two phases: construction of the 900 MW first phase is scheduled to begin in the fourth quarter of 2027 and finish in the fourth quarter of 2030; construction of the 300 MW second phase is scheduled to begin in the first quarter of 2031 and finish in the fourth quarter of 2032. These construction schedules refer to different milestones from the groundbreaking ceremony held on this occasion.

The project will use more than 425 hectares of land, including more than 414 hectares in Mường Bang commune. Local authorities have completed an inventory of land, assets and crops covering more than 70 hectares within the first phase’s land clearance area and the groundbreaking ceremony site. The chairman of the Son La provincial government said the project met the conditions for holding the groundbreaking ceremony a year ahead of the original plan. He called on the investor and contractors to control construction quality, safety and environmental impacts, and to continue compensation and resettlement work.
