Hydropower Country Notes

Indonesia

At some 2 150 TWh/yr, Indonesia's gross theoretical hydro potential is the third largest in Asia. Its technically exploitable capability is just over 400 TWh/yr, of which about 10% is considered to be economically exploitable. Average annual hydro output is about 9 200 TWh, indicating the evident scope for further development within the feasible potential. Hydro presently provides approximately 12% of Indonesia's electricity supply.

The Indonesian WEC Member Committee reports that 135 MW of hydroelectric generating capacity was under construction at end-2005 and that 802 MW of additional hydro capacity was at the planning stage.

The installed capacity of small-scale hydro plants is reported as 20.89 MW, with 2005 generation amounting to 55.71 GWh. Additional capacity of 17.31 MW is on order or planned.
