The use of fossil fuels for power supply of the Ukrainian Akademik Vernadsky station (UAC) in Antarctica does not meet Ukraine’s commitment to minimize the negative im pact on the environment and requires significant costs for its transportation to the station. Renewable energy sources (RES) can be used to solve this problem. The experience of other countries in this region confirms the efficiency of RES using to provide electricity to research stations. Modern algorithms for controlling the diesel generators operation allow the construction of hybrid power supply systems using wind and solar energy, which are characterized by high reliability of power supply and low consumption of diesel fuel.To assess the feasibility of using a wind power plant (WPP) and a photovoltaic power plant (PPS), long-term wind speed and solar radiation data were analyzed. As a result of the study, the possibility of using RES to provide UAC with electricity was established. The distribution of wind energy is smoother throughout the year, while solar energy is characterized by a significant decrease from May to June (to zero in July). The analysis of hourly synchronous graphs of WPP and PPS generation based on satellite data revealed a negative weak correlation between -0.14 (April) and -0.5 (September). Significant uneven generation of PPS  during the year and a negative correlation indicate the feasibility of simultaneous use of PPS and WPP, which will provide a more uniform supply of electricity from RES. The lack of electricity consumption data does not allow to determine the optimal RES capacity to ensure maximum compensation for the needs of UAC at this stage. When analyzing the operating modes of the station main equipment, it was established that there is a base load of 25 kW, which can be compensated by the RES. The use of RES with an installed capacity of 30 kW will provide from 8.6% (PPS) to 14.8% (WPP) of the UAC's annual electricity demand. This will avoid between 25 t (PPS) and 44 t (WPP) of CO2 emissions per year. Ref. 18, tab. 6, fig. 5.
