Offshore Wind Development

Preliminary studies carried out by NIWE across the coastline of India indicate good potential both off the Southern tip of the country and the West coast for offshore wind farm development in India. The offshore wind potential was assessed by the FOWIND (Facilitating Offshore Wind in India) consortium with NIWE as a knowledge partner. Based on a multi-criteria approach involving assessment of various parameters such as wind resource, bathymetry etc., eight zones each off the coast of Gujarat and Tamil Nadu were identified as potential offshore wind energy zones.

In consideration of the need for the holistic development of offshore wind farms in the country and in order to expedite the process, three models have been proposed and finalized. Additionally, the Potential Zones/Sub-zones have been identified and a strategy paper for offshore has been published on the website of the MNRE.

Marine Spatial Planning for offshore wind farms in Tamil Nadu

Under the Indo-Danish co-operation, NIWE & DEA has jointly carried out the Marine Spatial Planning studies consisting of various significant factors such as wind speed, water depth, marine traffic, hazardous area, Environmental sensitive zones, etc.,

Following an analysis of the offshore wind potential in the Gulf of Mannar, a set of zones and subzones have been prepared for the identified prospective zones and subzones for the development of offshore wind farms in the Gulf of Mannar, which is located off the coast of Tamil Nadu. Also, the subzones are realigned considering the MNRE strategy document for the development offshore wind in Gulf of Mannar, Off TamilNadu coast. The realigned sub zones are given below under different models as stipulated in the strategy document.
