No matter how much water there is, it will be released. The water level is limited and the maximum water storage capacity is 175 meters.
The Three Gorges Hydroelectric Power Station has a dam height of 181 meters, a normal water storage level of 175 meters, and a dam length of 2,335 meters. It has a static investment of 135.266 billion yuan and has installed 32 hydropower plants. units with a single capacity of 700,000 kilowatts. The last hydropower unit of the Three Gorges Hydropower Station was put into operation on July 4, 2012. This means that the Three Gorges Hydropower Station, with an installed capacity of 22.4 million kilowatts, has become the largest hydropower station and clean energy production base in the world. July 4, 2012.
Detailed information
The Three Gorges Dam project consists of two parts: the buildingmain and the diversion project. The total length is approximately 3,335 m, and the diversion project. The elevation of the dam crest is 185 meters. The total investment is 95.46 billion yuan. Construction officially began on December 14, 1994 and was successfully completed on May 20, 2006. Electricity output from the Three Gorges Hydroelectric Power Station exceeded 100 billion kilowatt hours in 2018, setting a new world record for annual electricity production from a single power plant.
With the approval of the State Administration of Defense, the Three Gorges Reservoir officially launched its fourth 175-meter experimental water storage at midnight on September 10, 2011. At 7 p.m. On the 18th, the water level in the reservoir had reached 160.18 meters. On July 23, 2012, the Three Gorges Project opened seven deep drainage holes to drain floodwaters. The upstream water flow has reachednt 46,000 cubic meters per second.
On July 24, 2012, the inflow from the Three Gorges Dam reached 71,200 cubic meters per second, the largest flood peak encountered since the creation of the Three Gorges Reservoir.
First of all, let me correct the above statement: the original plan for the Three Gorges Power Plant is 26 units of 700,000 kilowatts, which means a installed capacity of 18.2 million kilowatts and annual consumption. electricity production of 84.7 billion kWh. Later, an underground power station was built in the “Baishijian” mountain of the Right Bank Dam, and six 700,000 kilowatt hydroelectric generators were built. In addition, the Three Gorges hydroelectric power station itself has two 50,000 kilowatt power plants. The total installed capacity reached 22.5 million kilowatts and the annual production capacityof electricity is 100 billion kilowatt hours.
It is incorrect to directly multiply the installed capacity by the one-year period to calculate the annual electricity production. Can you guarantee that all units will operate at full capacity throughout the year? Certainly not. Firstly, there is not enough water and secondly, the unit also needs maintenance. It is therefore impossible to operate all the units continuously over the course of a year.
The current price of electricity on the Three Gorges Power Station grid is 0.25 yuan. According to this calculation, 1,000 × 0.25 = 25 billion.
The total investment of the Three Gorges project. is 180 billion, 1800÷250=7.2 years.
Since the annual electricity price income of the Three Gorges Hydropower Station is deducted from the cost factors, the cost can be recovered in about 15 years.
