The importance of assessing hydropower resources in recent years determines the study of the quantitative characteristics of river hydropower. Interesting and at the same time important for understanding the assessment of hydropower potential and its module is a multivariate analysis of the determining factors that determine their magnitude. This approach makes it possible to establish the impact and assess the possible relationship between natural and anthropogenic indicators on its formation. It is especially important to establish the factors that determine the magnitude of the modulus of the hydropower potential, an indicator by which it is possible to reflect the total hydropower of rivers in a spatial context.Since the magnitude of the hydropower potential and its modulus is influenced by numerous factors that may be weakly interdependent, it was decided to apply multivariate analysis to establish the most significant indicators using factor analysis. Studies have shown that hydropower, runoff indicators, catchment area, indicators of erosional activity of the catchment, and indicators of the river’s slope exert the greatest influence on the magnitude of the modules of the hydropower potential. The indicators of plowing, forest cover, and regulation indirectly affect the magnitude of the modulus of the total hydropower potential. In the course of the study, the dependences of the hydropower potential on the catchment area and the average annual water discharge, the module of the hydropower potential and the indicator of the depth of the erosional incision of the rivers were built. The connections are characterized by good degrees of correlation and can be used to calculate the magnitude of hydropower in rivers for which there are no or insufficient input data. In a conclusion, the use of factor analysis made it possible to establish a relationship between all 15 factors, according to 26 hydrological stations, and to identify the main determining factors influencing the formation and spatial distribution of the total hydropower potential module for the Pripyat basin rivers within Ukraine. According to the results of the calculation by the method of factor analysis, five main groups of factors with the corresponding factor load. The first two groups of factors accounted for more than 80% of the total variance of the distribution.
