## THE MINISTER OF NEW & RENEWABLE ENERGY AND POWER

## (SHRI R.K. SINGH)

(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) and salinity.

(b) The quantum of funds allocated for research and development (R&D) in the area of new and renewable energy technologies during the last three years (2018-19, 2019-20 & 2020-21) is Rs. 107 crore & during current year i.e. 2021-22 is Rs. 27 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)  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.
