Abstract
The article examines the economic aspects of the efficiency of power systems for mine loads, which include peak pumped-storage hydroelectric power plants that use reservoirs of the mine underground water drainage. The comparison of power supply options was carried out according to the net present value (NPV) criterion, which was determined by changing the water inflow through the hydro turbine and power consumption. As a result of numerical experiments, it has been established that the greatest economic effect can be achieved by implementing a pumped-storage hydroelectric power plant consisting of four hydroturbines, two of which will be used during the half-peak price hours, and at other times, when the peak price is used, all facilities will be used to.
