Survey of Energy Resources 2007
Tidal Country Notes
The main potential sites for tidal power generation are the Gulf of Kutch and the Gulf of Khambhat (Cambay), both in the western state of Gujarat, and the Gangetic delta in the Sundarbans area of West Bengal, in eastern India.
The tidal ranges of the Gulf of Kutch and the Gulf of Khambhat are 5 and 6 m, the theoretical capacities 900 and 7 000 MW, and the estimated annual output approximately 1.6 and 16.4 TWh, all respectively.
The West Bengal Renewable Energy Development Agency (WBREDA) prepared a project report (on behalf of the Ministry of Non-Conventional Energy Sources) for a 3.65 MW demonstration tidal power plant at Durgaduani Creek in the Sundarbans. This was followed by an environmental impact assessment study. In February 2007 the WBREDA stated that it had engaged the National Hydroelectric Power Corporation to implement the Rs 400 million (approximately US$ 10 million) project on a turnkey basis, with work likely to begin in the near future.
