N2 - Russia’s sources of electricity generation have been mainly from fossil fuels duel to the country’s abundant hydrocarbon resources, and nuclear power plants. The country has huge renewable energy potentials which are yet to be fully developed. This study evaluated the techno-economic potential of a PV/Wind/DG/Battery system for integration in Yekaterinburg and other rural areas around that enclave. The Hybrid Optimization of Multiple Energy Resources software was used in the simulation of the system, some financial metrics such as levelized cost of energy (LCOE) and the net present cost (NPC) were used in the analysis. Results from the monthly electricity generation indicate that a total of 75,469 kWh/year of electricity was produced from the hybrid system. The PV system produced 29,405 kWh/year representing 39% of the total electricity generated in a year. The wind system also produced 23,291 kWh/year which also represent 30.9% of the total electricity generated per annum, whiles the DG system produced some 22,773 kWh/year representing 30.1% of the total electricity generated by the hybrid system. An excess electricity of 2,353 kWh/year was generated which represents about 3.12% of the entire annual generated electricity. The system recorded an LCOE of 0.356 /kWh,NPCof255,478.80 and an operating cost (OC) of $9,409.72. The obtained results will be too expensive if implemented using the selected financial conditions. However, a sensitivity analysis conducted indicates that the cost of energy can be significantly reduced if some selected financial variables are changed.
