Comments

Around the town of Kremnica, miners have for centuries been drawing out natural treasures from the earth. The need to find a symbiosis between mining activity and water, which for miners is a good servant but bad master, gave rise to electricity generation, something we take for granted today. Located in spaces at the level of Kremnica’s Main Hereditary Adit, 245 metres below ground, an underground hydroelectric plant has since 1921 been transforming strong flowing water into electrical energy. It is a major feat of technical prowess. The length of the adit between shaft IV at Kremnica and its outlet at the Hron River is 11 km. The elevation over that distance is only 5.5 metres, and in places the water seems to flow into the hill. Shaft IV is today the only operational shaft at this location. The shaft, engine room, and hoist still operate in their original condition. With water flowing in at a rate of 1 200 litres per second, the plant has a generating capacity of 2.16 MW. With such plants being rare in Europe, the underground hydroelectric plant in Kremnica has been designated a Slovak national cultural heritage site. Its operator, the mining company Kremnická banská spoločnosť, s.r.o., aims to maintain the plant’s uniqueness and beauty, just as we have inherited it.
