benefits of location on high plateau
- cold temperature - low evaporation rates
- no displacement of people
- no villages/towns flooded
Many lakes combine on the …….? to form ……..?
Fjell, (1000m plateau) to from lake Blasjø.
Benefit of having deep narrow valleys in the area?
can be dammed to form low lying reservoirs if needed.
what moves the water between the two main reservoirs and the three generating stations?
pipes, pumps and tunnels.
where is water supplied from.
- Blasjø reservoir
- 39 rivers/brooks
function of Hylen and Saurdal PS?
to pump water from lower levels back up to higher levels of lake Blasjø. ensuring water supplies are kept, and so can cope with short term fluctuations in demand.
Capacity of Blasjø reservoir
3.1 billion tonnes of water.
what is the advantage of having 3 generating stations nearer to sea level than lake Blasjø?
a ‘large head’ of water can be created.
so large amounts of electricity can easily be generated.
Describe Kvilldal PS
has 4 large Francis turbines - can operate continuously if required.
