India”s Offshore Wind Energy Potential
India’s renewable energy market is among fastest growing markets in the world.India has consistently achieved top rank among other developed countries (globally) with respect to its market potential for renewable energy sources (RES) in the past decades.The fastest growing area in RES is observed to be wind energy,which accounts for about 70 percent of the total installed capacity in renewable energy with a cumulative onshore installation of nearly 20000 MW1.As a growing economy,the country is anticipated to witness an attractive investment option of offshore wind power generation in coming years.India has 7000kms long coastline with vast untapped potential supported with economic need,captive market,and technological experiences.While,it is estimated that offshore wind energy may overcome the existing barriers of power deficit in the country,the exploitation of this sector is yet to happen.In its efforts of bringing this sector on development scale,the Government of India recently released draft national wind energy policy 20132 which recognizes a significant amount of potential along southern coast of Tamil Nadu,and coasts of Kerala,Gujarat etc.The present study aims to provide a better and clear understanding of the long term wind resources prevailing along the country’s coastline.The overall aim of this work is development of Wind Map for coastal region of India within 40km distance from the administrative boundary and within water depth limit of 40m based on meso-scale modeling.The assessment is carried out in GIS using global datasets such as NCEP/NCAR Reanalysis 1 Project3 wind variables,SRTM+ bathymetry4,Global Land Use/Land Cover database5,and measured wind speed datasets procured from CWET.The study quantifies wind potential in GW across different coastal states of India using Vestas 7.0 MW wind turbine model6.The annual energy output is assessed over entire region of interest assuming Machine Availability of 95%,Grid Availability of 95%,Transmission Loss Factor of 95%.It also provides detail insights into potential capacity across coastline of two states Gujrat and Tamil Nadu,identified as higher potential states compared with others.The study also focuses on some of the key points in the strategic move made by MNRE,GoI in terms of technical and economical perspective to scale offshore development in the country as reflected in Draft National offshore wind energy policy2.
