  1. Kalpsar : A kayakalp project Biggest Tidal project in the world envisaged S R Awasthi

  2. Tidal power is dependent on the tides created by the moon’s gravitational pull on earth

  3. Potential : Places with highest tidal range gulf of Kutch in India

  4. Gujarat : Gulf of Khambhat

  5. Gulf of Khambhat

  6. Gulf of Khambhat

  7. Why a kayakalp project ? • fresh water reservoir = 2000 km2 • 12 rivers including Narmada, Mahi, Sabarmati, Dadhar • Dam = 64.16 km long and 35 m wide • Tidal power plant = 5,880 MW by installing bulb turbines of 40 MW each. • Highway multi-lane & a railway line across Gulf of Khambhat connecting Ghogha in Bhavnagar district in Saurashtra with Hansot in Bharuch District in South Gujarat, reducing distance by about 225 km. • Reclamation of land = 4 Lac hectares of saline will be replaced by fresh water.

  8. Modified plan • A new location under investigation reduing dam length to 29 kms • Estimation project cost reduction from Rs. 50000 Cr to Rs. 30000 Cr. • Execution : start = 2012 completion = 2020

  9. Types of Tidal Power Generation • Barrages • Tidal Streams

  10. Tidal Barrage • Turbines • Sluice gates • Embankments

  11. Bulb Turbine

  12. Straflo or Rim Generator Turbine

  13. Tubular Turbine

  14. Tidal streams • Instead of damming estuaries the tidal currents are harnessed using wind like turbines

  15. Main methods of current generation • Marine current generator • Stingray • Tidal fence
