Survey of Energy Resources 2007
Hydropower Country Notes
The overall potential for all sizes of hydropower is quite modest (technically exploitable capability: 3 978 GWh/yr). Total hydroelectricity output in 2005 was 2 401 GWh, representing 60% of the technical potential. Hydropower furnishes about 3% of the republic's electricity generation.
A relatively high proportion (nearly 40%) of the technically exploitable capability is classified as suitable for small-scale schemes; installed capacity in this category at the end of 2005 was 277 MW, equivalent to about 27% of the Czech Republic's hydro capacity. Actual generation from small-scale schemes in 2005 accounted for nearly 45% of hydro output, reflecting the higher average capacity factor achieved by small hydro compared with the larger stations.
