Micro-hydro schemes extract energy from water flowing downhill, without the need for large dams. A range of turbines can be used, depending on the rate of flow and the head available (i.e. the height the water is falling). In addition to the turbine, civil works are required to divert water from a stream into the turbine, and return it to the stream afterwards.
Pakistan’s total hydropower potential has been estimated over 40,000 MW, some 24,000 MW of which could be easily harnessed, and approximately 6400 MW of which is actually being exploited. More than 1000 MW micro/mini hydropower potential is available in northern mountainous region of the country, of which less than 2% is being Developed .Due to anticipated growth in demand and of the fact that only about 20% of the available hydropower potential is being utilised, the ‘vision 2025’ development plan provide first and foremost for the vigorous, multi-stage development of hydroelectric power.
