Small and medium-sized power plants.
Equivalent to the electricity consumption of a small county of 500,000 inhabitants. Typically, a 120,000 kilowatt power plant can produce 1 billion kilowatt hours of electricity per year, which is equivalent to the electricity consumption of a small county of 500,000 people. One billion kilowatt hours of electricity is the calculated value of electricity. The electricity reserve is the unit value of 1 billion kilowatt hours. We can also consider that the calculated value of electricity consumption is the value of 1 billion kilowatt hours. electricity. For example, through innovation this year, the State Grid Corporation of China increased the amount of stored electricity by 1 billion kilowatt hours to ensure the preparation and delivery of electricity consumed at high temperatures this year. Therefore, 1 billion kWh of electricity represents a staelectricity consumption statistics.
Huanren Hydropower Station is located in Huanren County, Liaoning Province, China, on the middle reaches of the Hunjiang River, the largest tributary on the Chinese side of the course main part of the Yalu River. The Hunjiang River is the main tributary of the Yalu River. It has its source at Laoling in the Changbai Mountains. It has a total length of 445 km, a height difference of 744 m and a drainage area of 14,776 square kilometers. There are many winding river channels and narrow valleys in many places, so the conditions for the development of water power resources are good. There are seven levels of river basin development, namely: Huanren Hydropower Station, Xijiang Hydropower Station, Fengming Hydropower Station, Huilongshan Hydropower Station, Taipingsh Hydropower Stationao, Shuangling Hydropower Station, Jinshao Hydropower Station, and then Shuifeng Hydropower Station on the Yalu River. Dams were built at three locations on the river, forming Huanren Reservoir, Huilongshan Reservoir, and Taipingshao Reservoir from upstream to downstream. By the end of the 20th century, the Hunjiang Cascade Hydropower Station had developed a total installed capacity of 500 MW and an annual electricity output of 1.26 billion kWh.
