European Green Deal + Poland + hydroelectric plants = Future?

This study considers the current state of hydropower in Poland and the legal and environmental conditions for its development. The research objective was to provide insights into the future of hydropower in Poland. An attempt was made to determine the direction of hydropower development in Poland by 2050, taking into account the requirements of the European Green Deal. The basic method used is logical argumentation, which is in turn based on a critical analysis of planning documents and scientific papers. Statistical data on the production and consumption of hydropower were also analysed. Currently, Poland’s potential for hydropower production is not being fully exploited. The main reasons for this are a lack of political support and socio-ecological issues associated with the need to take over inhabited areas or areas of high natural value. The analysis of the state of hydropower in Poland indicates that urgent intervention is required in many areas. This applies, especially, to issues of the control, modernisation and technical condition of hydropower plants and damming facilities. The potential for the development of hydropower in Poland is assessed to be very small. Environmental, socio-economic and legal conditions are unfavourable to the construction of new, large hydropower plants. The exception is pumped-storage power plants, which, acting as energy storage facilities, should in the future constitute an important element of the Polish energy system. The possibility of using defunct lignite mining pits for this purpose is indicated. It is shown that some of Poland’s former lignite mines are also conveniently located. The possible beneficial impact of building pumped-storage power plants into the water ecosystem of central Poland is emphasised.
