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

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

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

Gujarat : Gulf of Khambhat

Gulf of Khambhat

Gulf of Khambhat

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.

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

Types of Tidal Power Generation Barrages Tidal Streams

Tidal Barrage Turbines Sluice gates Embankments

Bulb Turbine

Straflo or Rim Generator Turbine

Tubular Turbine

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

Main methods of current generation Marine current generator Stingray Tidal fence
