The Yeywa Dam is located in the Mandalay Division in the middle of Myanmar . It dams the Myitnge River , a left tributary of the Irrawaddy . Approx. The city of Mandalay is 50 km northwest of the dam .

The first detailed plans for the project were carried out from August 2001. The construction of the dam began in February 2006. The construction was completed in 2010. The dam is used to generate electricity.

Barrier structure

The barrier structure is a gravity dam made of rolled concrete with a height of 132 (or 134) m. The top of the wall lies at a height of 197 m above sea level . The length of the top of the wall is 690 m. The volume of the structure is 2.43 (or 2.5) million m³.

The flood relief is in the middle of the dam, slightly offset to the right.

In order to dry out the construction site, two tunnels were driven through the rock walls on the right side of the river and the Myitnge was led through them. The tunnels are each 10 meters in diameter and 450 and 500 meters long. One of the tunnels was then closed and the other was converted into a bottom outlet so that water could be drained in a controlled manner even if all four turbine inlets were to be closed.

At the Yeywa dam, the coffer dam was built on the upstream side as part of the actual dam.

Reservoir

With the normal storage target of 185 m, the reservoir extends over an area of around 59 km² and holds 2.6 billion m³ of water - 1.6 billion m³ of this can be used to generate electricity. The minimum congestion destination is 150 m.

power plant

With an installed capacity of 790 MW, the power plant is the largest hydropower plant in Myanmar (as of March 2015). The average annual production is 3.55 billion kWh .

In 2010 4 machines with a maximum output of 197 (or 197.5) MW each were put into operation. You are in a machine house at the foot of the dam on the left. The Francis turbines were supplied by China National Electric Equipment Corporation .

The maximum flow rate is 210 m³ / s per turbine.

The power plant is owned by the Ministry of Electric Power of Myanmar State, but is operated by Myanmar Electric Power Enterprise .

Others

The total cost of the power plant was $ 600 million and $ 700 million, respectively.
