Which of the following coasts is the largest tidal energy producing area in India ?

The Gulf of Khambhat (also known as the Gulf of Cambay) on the Gujarat coast is the largest tidal energy producing area in India. It possesses the highest tidal range in the country, with an estimated power potential of approximately 7,000 MW. This is followed by the Gulf of Kutch, which has a potential of about 1,200 MW, and the Gangetic Delta in the Sunderbans region of West Bengal, with about 100 MW.

Tidal energy generation requires a significant difference between high and low tides (tidal range) to be commercially viable. The funnel-shaped geography of the Gulf of Khambhat amplifies tidal heights, making it the most suitable location. In contrast, the coasts of Mannar, Kerala, and the North Circars do not exhibit the extreme tidal ranges necessary for large-scale tidal power production.
