3 2 Where do you find us in the Olomouc Region? Visitor centre of the Pumped-Storage Power Station Dlouhé Stráně

4 3 Location: Kouty nad Desnou River: Divoká Desná Altitude of the generator room: 767,20 MASL Construction on the power station started:1978 Date of commissioning: 1996 Energy used capacity: MM cubic meters Installed capacity: 2 x 325 MW Head of power station: 534,3 m (the largest of a reversing turbine in Europe) Type of turbine: Francis (reversing) Turbine discharge (max): 68,5 cubic meters/sec Effectivity of the pumped-storage cycle:75,1 % The elevated storage reservoir spot height of the dam crest: MASL length of the dam crest: 1 742,5 MASL total capacity: MM cubic meters max surface submerged: 15,4 ha The lower reservoir spot height of the dam crest: 824,7 MASL length of the dam crest in the centre line:306 m total capacity : 3,405 MM cubic meters max surface submerged: 16,13 ha Basic technical data

5 4 Significance of a power station - power station works in quick start regime and by spotting the deviation of the energy system - it helps to optimize the operation of nuclear and coal-fired power plants Coal + Nuclear

6 5 it has later become one of the most touristic attractions in the Czech republic. It would have been refused by the public during the construction,

7 6 History of the construction of the power station 1978 – construction of the power station started1978 – construction of the power station started 1980‘s – then central bodies held up the project1980‘s – then central bodies held up the project 1985 – modernization of the project1985 – modernization of the project 1996 – date of commissioning1996 – date of commissioning

8 7 Environmental impact of the construction and operation of the power station Environmental impact - entire technology is located underground - technology used with no negative side effects on environment - all service water is being purified - landscape intervention caused by the construction of the power station has had no negative impact on the surrounding ecosystem - recultivation which followed the construction incorporated the power station in the natural surroundings

9 8 Further importance of the hydroelectric plant - popular tourist spot - tourist routes and cycle paths - positive effects on the development of tourism in the Desná Valley X - visit rate regulation due to the Protected landscape area of Jeseniky (need for close cooperation with the environmentalists) - cooperation with regional tourist development organizations and public administration

10 9 Public visits start at the Visitor center Visit rate of the visitor centre: approx visitors per year

11 10 And they continue to the Power Station „There is a machine unit placed deep in the underground of the mountain which rotates and produces the valuable electricity“.

12 11 Let‘s have a look in the generator room All technology is located 250 m underground = minimum impact on the environment

13 12 The uper reservoir – significant tourist spot Altitude of MASL – Beautiful scenery of main Jeseniky Mountains edge

14 13 Thank you for your attention Zdeněk Saturka
