Sweden
Sweden has one of the highest hydro potentials in
Western Europe: its gross theoretical capability is
reported to be 176 TWh/year, of which 90 TWh is economically
exploitable. The average annual capability of the
hydro capacity installed at the end of 1999 was 64
TWh, about 71% of the economic potential. Actual hydro
output in 1999 was 70.8 TWh: hydropower provides 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.
Tajikistan
The terrain and climate are highly favourable to the
development of hydropower. Apart from the Russian
Federation, Tajikistan has the highest potential hydro
generation of any of the FSU republics. Its economically
feasible potential is estimated to be 263.5 TWh/year,
of which only about 6% has been harnessed so far.
Hydropower provides over 95% of Tajikistan's electricity
generation.
There is just over 4 GW of hydro capacity installed:
the plants under construction will add another 4.6
GW. Hydropower & Dams World Atlas 2001 reports that
plans exist for installing a further 11.8 GW, which
would eventually bring Tajikistan's total hydro capacity
to over 20 GW, assuming that all the plans come to
fruition. The largest hydro plant presently under
construction is the huge Rogun scheme (3 600 MW) on
the river Vakhsh.
