integration of renewable energy at coal mining enterprises: problems and prospects

This article addresses the issue of developing renewable energy in coal mining enterprises in the russian federation. the study presents a methodology for assessing the technical and economic efficiency of introducing renewable energy sources based on simulation modeling. an analysis of the potential of solar and wind energy for coal mining regions in russia is conducted. the authors use a custom software developed by them to simulate the power supply system for various scenarios of renewable energy integration, including solar generation, wind generation, solar generation with energy storage, wind generation together with solar generation. based on the example of the rostov region, a feasibility study of the considered options is presented. additionally, the research includes a sensitivity analysis of the investment project in the conditions of uncertainty in the development of russian renewable energy. the research findings indicate that even in market conditions with co2 emission quotas and prices at the level of the sakhalin experiment, renewable energy in coal mining enterprises in russia remains unattractive and requires additional support.
