Projects under studies
Aiming to fulfill IWPCo objectives, "Technical and planning deputy" and "Development Projects" are developing hydropower potentialities using three methods of dam construction, i.e. storage, run-off-the river and pumped storage as well as projects for conveyance of water.
Therefore in all over the country, the rivers and their catchment-areas have been considered for different phases of studies.
More than 24 dam sites (For construction of large Power Plants), about 200 dam sites (for construction of small and medium-sized Power Plants) and several water conveyance directions have been studied for reconnaissance, feasibility and detailed design studies.
Other project studies such as:
- GIS software installation,
- Flood alarm system software installation,
- Catchment areas studies,
- Impounding of Karkheh River, etc. are being performed, aiming to serve other projects either under construction or under studies.
