Offshore Wind Energy

 / Research / In-House /FTR/ Potentials of offshore Wind Energy Resources

The Project

Wind, a major renewable energy resource, is a promising alternative to fast depleting fossil fuels. Offshore wind energy plays a crucial role in fulfilling the energy needs of the society and likewise in reducing adverse environmental effects. An attempt has been made to identify the offshore wind energy potential resource along the Indian coast.

  • Offshore wind speed varies between 8 to 11 m s-1 from the MSL to 140 m height along the Indian coast
  • The cumulative potential areas are found to be more on the west coast than on the east coast of India

Potentials of Offshore Wind Energy Resource for the coast of India

Aim

Quantify the biogeochemical controls of Greenhouse gas emissions in pristine and impacted mangrove ecosystems and determine emission inventories.

Objectives

  • Greenhouse gas emissions from Pristine and Impacted Blue carbon ecosystems

    • Identification of the processes governing emissions in coastal ecosystems through various field-based and laboratory-based measurements
  • Real time exchange of greenhouse gases and energy in mangrove ecosystems

    • Comprehensive understanding of the source-sink characteristics and the degree of biosphere-atmosphere coupling of mangrove ecosystems

Key Findings

  • Offshore wind speed varies between 8 to 11 m s-1 from the MSL to 140 m height along the Indian coast

  • The cumulative potential areas are found to be more on the west coast than on the east coast of India

  • The Tamil Nadu coast is the highest potential coastal area for the offshore wind energy followed by Gujrat coast, among all other coastal areas along the Indian coast

  • The maximum gross electrical power has been predicted at 50 m hub height at about 1,510 GW during southwest monsoon season and it varied between 250 and 800 GW in other seasons along the Indian coast

  • The total annual gross offshore electrical power is about 5,442 GW within the depth of 30- 200m

  • The available annual offshore wind energy power within the 12 NM is about 74GW and between the depths (30-50, 50-100, and 100-200 m) is about 421GW with the exclusion of marine protected areas, marine ecosystem, archaeological sites, bird migration, ship routes and cyclone prone areas

  • The total annual offshore wind power is estimated in the potential sites at ~495
