1. Which locality has the largest hydroelectric plant in Vietnam?

Exactly

Son La is the locality with the largest hydroelectric plant in Vietnam. The Son La Hydroelectric Plant started construction in 2005 and was completed in 2012, located in It Ong Commune, Muong La District, Son La Province. It is also known as the largest hydroelectric plant in Southeast Asia with a capacity of 2,400 MW.

The project has a total investment of about 60,000 billion VND, providing an average annual electricity output of more than 10 billion kWh and is responsible for flood prevention in the rainy season and water supply in the dry season for the Northern Delta.

2. What is the name of Vietnam's first hydroelectric plant?

  • Hoa Binh Hydroelectric Plant
  • Tri An Hydroelectric Plant
  • Ankroet Hydroelectric Plant
  • Yaly Hydroelectric Plant
Exactly

Ankroet is the first hydroelectric plant in Vietnam, built by the French in 1942 with mainly stone materials. Ankroet Hydroelectric Plant is located in Lat Commune (Lac Duong District, Lam Dong), and took many years to complete in a context where it relied mainly on human power and rudimentary support tools. With 2 generators, the initial design capacity was only 600 kW.

In 1960, to serve the construction of Da Nhim Hydroelectric Power Plant in Don Duong, the Japanese increased the capacity of Ankroet Hydroelectric Power Plant to 3,100 kW.

In 2004, Ankroet Hydropower Plant continued to be upgraded by Vietnam Electricity Group (EVN) to 4,400 kW in capacity, thereby increasing the average electricity output by nearly 22 million kWh/year, taking on the task of supplying electricity to Da Lat and connecting to the national power grid.

3. Which river has all three major hydroelectric plants?

  • Dong Nai River
  • Da River
  • Nho Que River
  • Hau River
Exactly

According to the Ministry of Science and Technology, the Da River is the largest tributary of the Red River system. The three hydropower plants on the Da River, Hoa Binh, Son La and Lai Chau, have a total capacity of 6,000 MW, making it the largest chain of plants on a river in Southeast Asia and contributing 30% of the country's electricity output.

4. Which hydroelectric plant in Vietnam was the largest in Southeast Asia in the 20th century?

  • Hoa Binh Hydroelectric Plant
  • Tri An Hydroelectric Plant
  • Lai Chau Hydroelectric Plant
  • Yaly Hydroelectric Plant
Exactly

Hoa Binh Hydropower Plant was built with the help of the Soviet Union in 1979. After nearly 15 years of construction, in 1994, the project was completed with 8 turbines, with a total installed capacity of 1,920 MW. Before 2010, when Son La, Lai Chau, Huoi Quang, Ban Chat hydropower plants did not exist, Hoa Binh Hydropower Plant was the power source with the largest installed capacity in Vietnam and Southeast Asia. This record was not broken until the Son La Hydropower Plant was inaugurated in 2012.

5. Which country has the largest hydroelectric plant in the world?

  • America
  • China
  • Brazil
  • India
Exactly

The Three Gorges Dam in Hubei, China is the world's largest hydroelectric dam in terms of electricity output. The plant can produce about 22,500 MW of electricity, and the construction cost of this dam is up to 37 billion USD.

Construction of the dam began in 1994 and was not officially completed until 2012. The giant power plant has 32 main turbines and 2 small generators. Each turbine has a capacity of 700MW, with 2 generators for 100MW.
