## STATEMENT REFERRED TO IN REPLY TO LOK SABHA STARRED QUESTION NO. 178 FOR ANSWER ON 09.12.2021

- (a) The Indian Institute of Technology, Chennai in association with Credit Rating Information  Services  of  India  Limited  (CRISIL)  conducted  a  study  on  'Tidal  &  Waves Energy in India: Survey on the Potential & Proposition of a Roadmap' in December 2014. As per  this  report,  the  state-wise  estimated  theoretical  tidal  and  wave  power  potential  are  as follows:-

| State          | Tidal Power Potential (MW)   | Wave Power Potential (MW)   |
|----------------|------------------------------|-----------------------------|
| Andhra Pradesh | 100                          | 6,900                       |
| Gujarat        | 10,425                       | 4,100                       |
| Karnataka      | 100                          | 6,100                       |
| Kerala         | 100                          | 4,900                       |
| Maharashtra    | 200                          | 8,100                       |
| Odisha         | 400                          | 600                         |
| Tamil Nadu     | 230                          | 10,600                      |
| West Bengal    | 900                          | --                          |
| Total          | 12,455                       | 41,300                      |

The study has not estimated the potential of Ocean Thermal Energy Conversion (OTEC).

- (b) During the last three years, the quantum of funds allocated for research and development (R&D) in the area of new and renewable energy technologies is Rs. 107 crore. The R&D budget  of  the  Ministry  is  a  composite  one  without  specific  allocations  for  different technologies. Since no viable R&D project was received, no R&D funds have been spent on ocean energy R&D projects.
- (c) 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.
- (d)&(e) Reply is given in part (a) above.
- (f) Globally, ocean energy is still at a nascent R&D stage. MNRE under its Research, Design, Development and Demonstration (RD&D)  programme  provides financial support to academic institutions, research and development organisations and industry for research and development  in  renewable  energy  projects,  which  can  also  possibly  include  projects  for developing Ocean Energy technologies.
