Study of the impact of climate change on the volume of electricity production at HPPs in Ukraine

Based on statistical data for 1996–2020, the influence of average annual fluctuations in air temperature and precipitation on the volume of electricity production by hydroelectric power plants in Ukraine is analyzed. During the period under investigation, a steady increase in air temperature is predicted. An analysis of model data was carried out to determine the general trends of climate change based on averaged, minimum and maximum climatic characteristics for the entire territory of Ukraine. For this, the average values of the forecasted series of data were obtained, which were averaged, as a result of which data sets were obtained, and the air temperature and precipitation averages for the seasons, year and decade of the 21st century were calculated from the monthly data. A forecast of average annual air temperatures and the corresponding amounts of electricity produced by HPPs for the period 2025–2050 is given.
