Postępujące globalne ocieplenie stwarza rosnące zagrożenie dla bezpieczeństwa dostaw energii w postaci zjawisk „blackoutu”. Celem artykułu jest ocena celowości inwestycyjnej projektów bezpieczeństwa energetycznego przepompowni wód dołowych. Połączenie problematyki odwadniania opuszczonych kopalń, wykorzystania OZE i magazynowania energii dla poprawy bezpieczeństwa zasilania przepompowni nie było dotychczas przedmiotem badań naukowych. Zaprzestanie odpompowywania wód dołowych naraziłoby sąsiednie kopalnie i niżej położone tereny na zalanie. W artykule przeanalizowano cztery technicznie wykonalne warianty modernizacji przepompowni wód kopalnianych. Każdą z opcji charakteryzuje inny poziom bezpieczeństwa dostaw energii i inny poziom zaspokojenia zapotrzebowania na energię. Wszystkie warianty modernizacji przepompowni uwzględniają wytwarzanie energii elektrycznej na własne potrzeby.

Increasing global warming poses a growing threat to the security of energy supply in the form of "blackout" phenomena. The purpose of this article is to assess the investment appropriateness of mine water pumping station energy security projects. The combination of the problems of dewatering abandoned mines, application of RES and energy storage to improve the security of power supply to pumping stations has not yet been the subject of scientific research. The cessation of mine water pumping would expose neighboring mines and lower—lying areas to flooding. This paper analyzes four technically feasible variants for upgrading mine water pumping stations. Each option is characterized by a different level of energy supply security and a different level of energy demand satisfaction. All of the modernization options for the pumping stations include the generation of electricity for own use.
Purpose: Growing global warming increases the threat of energy supply security in the form of the “blackout” phenomenon. Pumping stations pump out approximately 100 million m3 of water annually (data from 2023). Discontinuation of mine water pumping would expose neighbouring mines and lower-lying areas to flooding. Design/methodology/approach: For the designed database of functional scenarios of the mine water pumping station, the optimal variant was selected based on economic and ecological criteria as well as the energy security criterion. Findings: The research analyzed five technically feasible variants of modernization of mine water pumping stations. Each variant is characterized by a different degree of security of energy supply and a different level of meeting energy demand. Research limitations/implications: All variants of modernization of the pumping station provide for the production of electricity for own needs. All investment attractiveness factors should be taken into account while making investment decisions. It is up to the decision-maker to make the final multi-criteria decision so as to implement the selected variant. Practical implications: One of the challenge is to ensure security of energy supplies in the event of a sudden energy shortage. Pumping stations have some retention, nevertheless a longer shutdown time could lead to environmental problems. Removing the damage would definitely require large financial expenditures and would take several years. Social implications: The planned project of the energy supply security can have a positive impact on the local community and economy. The projects discussed will create new markets related to "green energy". Originality/value: The aim of the article is to assess the investment relevance of safety projects for power supply to mine water pumping stations. The combination of the problems of drainage of liquidated mines, the use of renewable energy sources and energy storage to improve the security of power supply to pumping stations has not been the subject of scientific research so far.
