The second turbine of the Hoa Binh Hydropower Plant expansion project in northern Phu Tho province was officially connected to the national grid on November 14.
Earlier, its first turbine was successfully installed and connected to the national grid on August 19.
The project comprises two turbines with a total capacity of 480 MW and an average annual output of 490 million kWh.
The key project was approved by the then Prime Minister in 2018 with the investor being the Vietnam Electricity (EVN) with total investment capital of over VND9.22 trillion ($350 million).
The entire project is expected for completed by the end of the year.
Once completed, the expansion will increase peak load capacity, improve frequency regulation and system stability, reduce the operational intensity of existing units, thereby extending equipment lifespan and lowering maintenance costs, and contributing to a more secure, stable, and economically efficient national power grid.
