Hydropower Country Notes
Sweden has one of the highest hydro potentials in Western Europe: the Swedish WEC Member Committee reports a gross theoretical capability of 130 TWh/yr, of which 85 TWh is economically exploitable. The average annual capability of the 16 100 MW hydro capacity installed at the end of 2005 was 65 TWh, about 76% of the economic potential. Actual hydro output in 2005 was 72 TWh, which provided nearly half of Sweden's electricity generation. The construction of new hydro plants has virtually stopped, on account of environmental and political considerations. Future activity is likely to be very largely confined to the modernisation and refurbishment of existing capacity.
There is 985 MW of small-scale hydro capacity installed, which generated a total of 3.8 TWh in 2005.
