According to the 2030 EU climate and energy framework, the share of renewable energy sources should amount to at least 27% of EU energy consumption [1]. Energy production with the use of hydropower plants is widespread globally, accounting for one fifth of the total global power generation [2]. Poland, a medium-size country in central Europe, has the entire panoply of possibilities to further develop and expand effective sources of electrical energy, which use the power of water flow to produce energy. Due to Poland’s geographical localization, vast majority of watercourses streaming through the country have their river head and river mouth inside the Polish territory. Therefore, the process of development of hydropower sector rests with Polish politicians forming energy policies. In 2017, hydroelectric power plants in Poland reached a total capacity of 2.376 GW, which is 5.5% of the capacity installed in the Polish energy sector and produced 2767 GWh of electricity, covering 1.7% of the country's demand [3]. In addition to the larger hydroelectric power plants, there are also over 700 small hydropower plants [4] that are officially classified as renewable energy sources, not hydroelectric power sources, hence their power is not added to hydropower reports. To be called a small hydropower plant in Poland, the source installed capacity must be under 5 MW. In 2017, all small hydropower plants achieved a total capacity of 0.988 GW [5]. The main condition that the river must meet in order to be used in the energy production process is the flow rate higher than the minimum allowable flow, defined as the minimum flow rate to be maintained in a watercourse perpendicular to the structure to maintain biological balance and water consumption downstream [6]. In Poland, this parameter for most rivers is defined and published by the Institute of Meteorology and Water Management (IMGW). If the watercourse chosen for the construct[...]
