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

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
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

Public visits start at the Visitor center
Visit rate of the visitor centre:
approx. 60 000 visitors per year
