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

It would have
been refused
by the public
during the
construction,
it has later
become one of the
most touristic
attractions in the
Czech republic.
History of the construction of the power station
• 1978 – construction of the power station started
• 1980‘s – then central bodies held up the project
• 1985 – modernization of the project
• 1996 – date of commissioning
6
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
7
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
8
Public visits start at the Visitor center
Visit rate of the visitor centre:
approx. 60 000 visitors per year

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“.

Let‘s have a look in the generator room
All technology is located 250 m
underground = minimum impact on
the environment
The uper reservoir – significant tourist spot
Altitude of 1 350 MASL – Beautiful scenery of main Jeseniky Mountains edge
