Abstract
The high energy intensity of mining enterprises and rising electricity tariffs necessitate the search for cost reduction methods, including through the integration of renewable energy sources (RES). The study aims to conduct a comparative economic analysis of different RES configurations (PV, wind, and hybrid systems) for power supply to mining enterprises. The objectives are to assess the economic efficiency of standalone PV and wind power plants, analyze the performance of hybrid solutions, and determine the impact of the regional factor. The research is based on discounted cash flow methods (NPV calculation) and project life cycle analysis. The key findings are: the economic efficiency of RES is highly location-dependent, wind power plants show the best results, being cost-effective in 5 out of 7 regions, whereas PV plants are profitable only in 3, hybrid systems mostly showed no significant advantages over standalone wind power plants, except in certain regions, the highest efficiency of wind power plants was achieved in Arctic and coastal zones.
