Potential assessment plays a key role for small hydropower (SHP) development. There is a huge untapped hydropower potential in India. Uttaranchal is one of the important states of India in terms of Small Hydropower potential. To tap the enormous available hydropower potential in Uttaranchal state, software Integrated Method for Power Analysis (IMP) 5.0 has been used for flow simulation in district Tehri Garhwal of Uttaranchal State. IMP software is an user-friendly tool of potential assessment for SHP development on ungauged sites. It is useful for preliminary estimates of energy potential. The software includes tips about hydrologic analysis of ungauged sites. IMP uses topographic and daily weather data, which the user inputs to generate daily stream flow. The water budget and time constant parameters are fixed by using observed discharge data of a site in the study area. The fixed parameters are used along with the watershed data and meteorological data to simulate the flow of ungauged sites. Using the simulated data, flow duration curves for the SHP potential sites are drawn which can be used to assess the power potential.
