## ANSWER

## THE MINISTER OF NEW & RENEWABLE ENERGY AND POWER

## (SHRI R.K. SINGH)

(a) to (h) As per a study conducted by the Indian Institute of Technology, Chennai in association with CRISIL Risk and Infrastructure Solutions Limited in December 2014, the tidal power potential of the country is estimated at around 12,455 MW. The potential areas with low/medium tidal wave strength are in the Gulf of Khambat & Gulf of Kutch in Gujarat, Palk Bay-Mannar Channel in Tamil Nadu, and Hoogly river, South Haldia & Sunderbans in West Bengal.

The State-wise estimated theoretical potential of tidal energy is as follows:

| State       | Estimated Theoretical Potential (MW)   |
|-------------|----------------------------------------|
| Gujarat     | 10,425                                 |
| West Bengal | 900                                    |
| Odisha      | 400                                    |

| Tamil Nadu     | 230    |
|----------------|--------|
| Maharashtra    | 200    |
| Andhra Pradesh | 100    |
| Karnataka      | 100    |
| Kerala         | 100    |
| Total          | 12,455 |

The earlier  efforts  for  harnessing  tidal  power  were  not  successful  due  to  high  capital  cost  ranging from Rs. 30 crore to Rs. 60 crore per MW. MNRE had sanctioned a demonstration project for setting up of 3.75 MW capacity tidal power plant in Sunderbans region in West Bengal in 2007. However, the project was not taken up by the Govt. of West Bengal due to high capital cost of Rs. 238 crore. Similarly, the Govt. of Gujarat had proposed 50 MW tidal power project in 2011. This project was also not taken up by Govt. of Gujarat due to high capital cost of Rs. 750 crore.

At present, due to very high capital cost, the Government of India has not put in place any policy or programme for production of tidal energy.
