Types of Hydro Power Projects

  • Run-Off the river Project

–Normal flow in a river which otherwise is un-utilised is used for generating power

–May require small storage facility

–Project based on stipulated dependability (90 %)

  • Dam Storage based Projects

–releases of dam are passed through the generating units resulting in added benefits along with irrigation needs

–may cater as base load plant also

  • Canal Based Projects

–utilises the drop (also sometimes called rapids) in a stretch of canal

–requires a diversion canal arrangement

  • Pumped Storage Plants

–concept based on differential tariff structure

- peak time tariff and normal tariff

–Pumps water utilising power available (at lower tariff) during normal hours to a higher altitude

–utilising this storage, and generates power during peak time (charged at higher tariff)

  • Tidal Projects

–utilises the energy of waves
