In 1920 they approved a plan of electrification of the RSFSR, thus initiating industrialization of the USSR. They began to introduce electricity into agriculture. Small hydropower plants called 'farm hydropower plants', supplied farms, stockyards and farmers' houses with electricity. However, later adoption of big hydropower plants made 'farm plants' needless, so the biggest part of them disappeared without a trace. Those which have
remained, may be found along the rivers of the USSR, including Moscow area, and this is where we are now. They built different types of 'farm hydropower plants' in the USSR. There were barrage power plans in the western part of the country; in the Caucasus, the Crimea and the Urals, they had derivation power plants. The dams differed as well. There were concrete, metal (movable) and wooden (movable) dams.
