The Dniebohe Hydropower Station 1 Reservoir has a total storage capacity of 2.46 billion m3 and an effective storage capacity of 530 million m3. It is a seasonally regulated reservoir with a submerged area of 78km2 and an average annual power generation of 3 billion kW·h, and it was the largest hydropower station in the world at that time. It was built from 1927 to 1939 with the assistance of American engineers. Its electricity is directly supplied to the newly-built Zaporoge Iron and Steel Complex. This power station is a symbol of socialist industrialization in the Soviet Union. 1941June, the Great Patriotic War broke out, and on the eve of the fall of Kiev at the end of September, the Soviet Supreme Command ordered the bombing of the power station, making it impossible for the Nazis to obtain electricity. 1944 after the liberation of Ukraine, the restoration project started, 1947 the first unit was put into production, and 1950 the restoration project was completed. The restored hydropower station has a total storage capacity of 3.32 billion m3 and an effective storage capacity of 850 million m3. The installed capacity has increased to 650,000 kilowatts, with an average annual power generation of 3.64 billion kilowatt-hours .. 1969. The Niebo II hydropower station has been built on the left bank of 1 power station, with an installed capacity of 828,000 kW, an average annual power generation of 5 billion kW·h, and a total installed capacity of1478,000 kW. No.2 expansion hydropower station 1969 started construction, 1974 first unit was put into operation, and 1975 project was completed. The project has comprehensive benefits such as power generation and shipping. Dnieper Reservoir was formed due to the construction of Dnieper Hydropower Station (654.38+0.48 million kilowatts). It was impounded in 1933, with an area of 4 10 square kilometers and a storage capacity of 3.3 billion cubic meters. The average depth is 8.2 meters and the water level changes by 2.9 meters. The reservoir has improved the navigation conditions of the Dnieper River, making it navigable below Kiev. Urban water supply, irrigation and fishing are still beneficial.
