Load decrease on the environment in the building of pump storage plant (PSP)

Problem statement. Energy in Ukraine is produced by a large number of generating power plants of various types. But, despite the significant environmental benefits, the use of unconventional energy sources does not solve the main problem - providing electricity to consumers with the required amount and at the right time. The unevenness of electricity consumption in the course of the day requires the availability of reserve and regulatory capacities that would meet the peak needs of industry and society. Generation of energy in the "on-demand" mode can only be performed by hydro (HES), pump storage plants (PSP), which at the same time have a significant impact on the environment. The purpose of the article is to determine the possibility of designing and construction of a PSP with a reduction of the load on the environment. The presentation material. Solving the problem of uneven electricity consumption requires the use of regulatory capacity of PSP, which are the most mobile ones. The cost of construction of the PSP is largely determined by their location, approaching electricity consumers and the need to compensate for environmental risks. Reducing the load on the environment can be achieved with a comprehensive consideration of the environmental needs of various sectors of the economy. As the example of Rybalskyi quarry, located in the city of Dnipro,it is the expediency of placing on its territory the PSP. The calculation of the potential capacity of the PSP will be determined by optimization calculations, for which the boundary conditions are formulated. Conclusions.The analysis of the possibilities of reducing the impact on the environment during the construction of the PSP has shown that there is a possibility of the construction of the PSP without any environmental risks. A place has been determined for the possible construction of such a PSP and an optimization task has been formulated to determine its power. The estimated payback period of the design project is five years.
