URL More about Čierny Váh Pumped Storage Power Plant
The pumped storage hydro power plant (PSHPP) Čierny Váh is situated in the valley of the river Čierny Váh, approximately 10 km above its confluence with the Biely Váh River near the Kráľová Lehota municipality, which is a part of the Low Tatras National Park protected zone. It is a construction with daily water accumulation that participates in the functioning of the frequency regulation and of the distribution of electricity to the grid. This hydraulic structure consists of four parts: an upper and a lower reservoir, penstocks and a power station. The lower reservoir was created by means of damming up the valley of the Čierny Váh by a 375 m long dam. Its capacity is 5.1 million m3. The level fluctuates by 7.45 m between elevations 726.00 – 733.45 m. The upper reservoir of an irregular shape is situated between the valleys of the Biely Váh and the Čierny Váh. It has a maximum capacity of 3.7 million m3 of water and the level fluctuates by 25 m between the elevation points 1160 – 1135 m above sea level. The sealing of the slopes and of the bottom is provided by one layer of asphalt concrete sealing blanket with a surface of approximately 200,000 m2. Underneath the reservoir, there is an inspection tunnel that should collect the potential seepages from the reservoir bottom and slopes. The hydraulic connection of the upper and lower reservoir is ensured via three pressure penstocks which have an internal diameter of 3.8 m. In the valley, they split into pipes that transport the water to the two turbines and outlets of water from the two accumulation pumps. The maximum head between the upper and the lower reservoirs is 434 m. The lower reservoir dam includes also a power station with a control room. There are six pumping turbo aggregates installed that comprise a motor generator, a Francis turbine and an accumulation pump. When 6 accumulation pumps are in operation, it takes 8 hours to pump the water into the upper reservoir. Source:
