52 India now ranks 4th in the world after Germany, USA and Spain with a wind power installed capacity of 4434 MW. The 10th Plan aim at 1500 MW grid-interactive wind power has been exceeded as capacity deployed upto 31.12.2005 exceeded 2800 MW taking the cumulative deployment to over 4500 MW.  On current trends, grid-interactive wind power deployment could be around triple the Plan target. 8.2 Wind Resource Potential India’s wind power potential has been assessed at around 45,000 MW assuming 3% land availability for wind farms requiring @12 ha/MW in sites having wind power density in excess of 250W/sq.m. at 50 m hub-height.  The potential for grid-interactive wind power would be less (around 15,000 MW) if sites having wind power density in excess of 300 W/ sq.m. at 50 m hub-height are considered in keeping with international practice. 8.3 Wind Resource Assessment Under a special study sponsored for Wind Resource Assessment in the North Eastern Region, 22 wind monitoring stations have been  set  up  with  25  m  masts  during  2005-06  in Tripura,  Manipur,  Mizoram, Assam, Arunachal  Pradesh  and  Sikkim.  Data collection from another 47 wind monitoring stations established under various programmes is in progress. 21 Wind Monitoring Stations with 50 metre tall mast were commissioned in 11 states namely, Chhattisgarh, Haryana, Jharkhand, Kerala, Karnataka, Madhya Pradesh, Maharashtra, Rajasthan, Tamil Nadu, Uttar Pradesh and West Bengal. The C-WET has published 7th volume of Wind Energy Resource Survey in India containing wind energy resource data collected from 26 stations covering the States of Tamil Nadu, Karnataka, Andhra Pradesh, Maharashtra, Madhya Pradesh and Gujarat. It is also proposed to prepare a Wind Atlas for India under the UNDP-CEC CCF-II Project. 8.4 Testing and Certification Testing and Certification services are offered by C-WET. Accreditation of testing services by National Accreditation Board for Laboratories is under way. It has been planned to enhance the test facility at wind turbine test station Kayathar. C-WET has evolved Type Approval Provisional Scheme – 2000 for the country. Provisional Type Certification of one wind turbine model has been completed and it is underway for nine wind turbine models. Three draft Indian Standards have been prepared for Safety Requirements, conformity testing and certification of wind turbines and power performance testing. Wind Turbines Installed at Sogi, Karnataka
