Hangzhou Jianghe Hydropower and Haili Investment Consulting Construction Group Co., Ltd. recently completed the signing of the contract for the Beijiang Hydropower Station project in Ningping Province, Vietnam. This hydropower station located in Lang Son Province will be equipped with two 7MW axial-flow turbine generators, with a total installed capacity of 14MW. It is planned to be officially connected to the grid and put into operation in July 2027. The project site selection is of great strategic significance. Liangshan Province not only has abundant water resources, but also borders Guangxi, China. Its unique border geographical location provides natural convenience for subsequent equipment operation and cross-border power dispatch.

Border Water and Electricity Supply Industrial Belt

Vietnam is currently in a period of accelerated industrialization, and the contradiction between electricity supply and demand is becoming increasingly acute. According to the latest data from Vietnam Electricity Group, the total electricity consumption in Vietnam is expected to increase by 8.5% year-on-year in 2025, and the summer electricity gap in northern industrial towns may widen to 12 billion kilowatt hours. The designed annual utilization hours of the Beijiang hydropower station reach 4800 hours, and the expected annual power generation after commissioning is 67.2 million kilowatt hours, which can directly alleviate the industrial electricity pressure in Liangshan and surrounding Beijiang Province.

Unlike traditional high head impulse units in Vietnam, the axial flow units used in this project are designed specifically for low head and high flow scenarios, with a maximum flow rate of 1300 cubic meters per second, and can maintain stable output during dry seasons. This model selection not only matches the average water head of the local river of 12 meters, but also shortens the equipment manufacturing cycle by 3 months, ensuring to catch up with the peak electricity consumption in 2027.

Standardized modules reduce costs and increase efficiency

To control costs, the project extensively adopts modular prefabrication technology based on Chinese standards. The project leader of Haili Group revealed that the civil engineering of the power station will use prefabricated cabin structures, reducing on-site assembly time by 40% compared to traditional methods. In addition, the power station access system has completed technical docking with the Vietnam State Grid and will be equipped with a 110kV booster station, which will be connected to the main grid through a 25 kilometer transmission line.

With the implementation of RCEP tariff reduction policies, the cost of energy equipment trade between China and Vietnam has decreased by about 5%. Hangzhou Jianghe Hydropower enters the northern Vietnam hydropower upgrading and transformation market through this project, and its next goal is to develop cascade power stations in Dong Nai Province. It is expected that the investment in clean energy in Vietnam will exceed 500 million US dollars in the next three years.Editor/Cheng Liting
