The dam Mianhuatan is a dam with hydroelectric power plant in the province of Fujian , China . It dams the Ting Jiang into a reservoir. The associated power plant has an installed capacity of 600 MW . In addition to generating electricity, the dam is also used for flood protection and irrigation.
history
In the early to mid-1990s, the People's Republic suffered from insufficient electricity generation capacities, which led to frequent power cuts. The shortage occurred particularly during peak load times . The government therefore asked the Asian Development Bank to finance the Mianhuatan project. A hydropower plant was to be built with the dam, which, due to its storage space, would be particularly suitable for covering peak loads. In addition, the project should improve flood protection.
The construction contract was awarded in July 1994. Construction work began in April 1998. The impoundment began in December 2000. In March 2001 the barrier structure was completed and in April of the same year the first machine was put into operation. The last machine was commissioned in December 2001.
Barrier structure
The barrier structure is a gravity dam made of rolled concrete with a height of 111 (or 113) m. The length of the wall crown is 308.5 m. The volume of the structure is 615,000 m³.
The design flood is 12,000 (or 15,500) m³ / s; the probability of this event occurring was determined to be once in 500 (or 5000) years.
Reservoir
At the normal storage target , the reservoir extends over an area of 64 km² and holds 1.698 billion m³ of water - of which 1.122 billion m³ can be used to generate electricity.
power plant
The power plant has an installed capacity of 600 MW . The average annual production is 1.52 billion kWh . Each of the 4 machines in the power plant has a maximum output of 150 MW. You are in a cavern on the left side of the river.
Others
In December 1995, the Asian Development Bank granted a credit line of $ 170 million . Of this, $ 53 million has been drawn. The loan was repaid early in April 2003. At the time of the loan, the cost of the project was estimated at $ 721 million; the actual cost would then be $ 437 million.
