When forming the perspective ways of developing the power industry of Ukraine should take into account the experience of both domestic and world science. The reduction of organic fuels and the growing environmental problems are attracting increasing interest in the use of natural renewable energy sources (RES). The last few decades of renewable energy development have been marked by the process of refining RES technologies: new developments in energy efficiency, progress in the development of energy equipment and software, achievements in the area of energy conservation. In Ukraine, on the territory of the Azov-Black Sea coast, there are many attractive sites for the construction of small hydroelectric stations [8, 9, 10]. One of these sites for the creation of a small PSP can be the area about. Snake in the Black Sea. Currently, on this island, electricity generation for local consumers is carried out using diesel and solar power plants, and wind power is also under construction. In the future, electricity consumption will increase, and therefore the emergency and volatile situation in the supply of electricity to consumers will increase. The requirements for standby power-driven power supplies will increase, in proportion to the increase in installed power of solar and wind power plants. One of the solutions to this problem may be the construction of a small PSP, which does not require a lower and large upper reservoir. One or more pressure vessels can be used as an upper reservoir, and the sea will serve as the lower one. From the large range of pumps, you can choose those that by type and characteristics meet their use as a hydrostatic return action. For the choice of power equipment of small PSPs, it may be promising to use as turbines and generators of series pumps and electric motors. The selected standard size pump pump for a small HPP will equip the station with an inexpensive, reliable hydromotor, which provides the efficiency of energy conversion at the level of 70-75%.
