Wind is an intermittent and site-specific resource of energy and therefore, an extensive Wind Resource Assessment is essential for the selection of potential sites. The Government, throughNational Institute of Wind Energy (NIWE), has installed over 800 wind-monitoring stations all over country and issued wind potential maps at 50m, 80m and 100m above ground level.The recent assessment indicates a gross wind power potential of 302 GW in the country at 100 meter above ground level. Most of this potential exists in seven windy States as given below:-
| S.No. | State | Wind Potential (MW) |
|---|---|---|
| 1 | Gujarat | 84431.33 |
| 2 | Rajasthan | 18770.49 |
| 3 | Maharashtra | 45394.34 |
| 4 | Tamil Nadu | 33799.65 |
| 5 | Madhya Pradesh | 10483.88 |
| 6 | Karnataka | 55857.36 |
| 7 | Andhra Pradesh | 44228.60 |
| 8 | Kerala | 1699.56 |
| 9 | Telangana | 4244.29 |
| 10 | Odisha | 3093.47 |
| 11 | Chhattisgarh | 76.59 |
| 12 | West Bengal | 2.08 |
| 13 | Puducherry | 152.83 |
| 14 | Lakshadweep | 7.67 |
| 15 | Goa | 0.84 |
| 16 | Andaman & Nicobar | 8.43 |

The Wind Turbine Generator technology has evolved andstate-of-the-art technologies are available in the country for the manufacture of wind turbines. Around 70-80% indigenization has been achieved with strong domestic manufacturing in the wind sector. All the major global players in this field have their presence in the country and over 31 different models of wind turbines are being manufactured by more than 15 different companies, through (i) joint ventures under licensed production (ii) subsidiaries of foreign companies, and (iii) Indian companies with their own technology. The unit size of machines has gone up to 3.00 MW.The current annual production capacity of domestic wind turbines is about 8000 MW to 10000 MW.
The Revised List of Models & Manufacturers is the list of type and quality certified wind turbine models eligible for installation in the country in order to facilitate SNAs, investors, lenders and developers. This list is based on the provision of type certification and quality assurance of wind turbines in India as per Guidelines for Development of Onshore Wind Power Projects issued by this Ministry vide F. No. 66/183/2016-WE dated 22 October 2016. As per the said guidelines, type and quality certification by an Internationally Accredited Certification Body shall be a mandatory requirement for manufacturers of wind turbines and components and the both certifications should mandatorily include Hub and Nacelle assembly/manufacturing facility in India.
In order to promote the local manufacturing of the wind energy turbine and its components Ministry issues CCDC certificates to the recognized manufacturers as per the Ministry of Finance notification no. 50/217-Customs dated 30.06.2017. For ensuring quality and safety of the wind turbines and components only Type Certified wind energy turbines which are empaneled in the RLMM list of the Ministry are considered for issuance of CCDC. Besides, the imported parts/components must be adhered to the design/suppliers as per valid type certificate only.
India’s wind energy sector is led by indigenous wind power industry and has shown consistent progress. The expansion of the wind industry has resulted in a strong ecosystem, project operation capabilities and manufacturing base of about 10,000 MW per annum. The country currently has the fourth highest wind installed capacity in the world with total installed capacity of 35.01 GW (as on 31st October 2018) and has generated around 52.66 Billion Units during 2017-18.
The Government is promoting wind power projects in entire country through private sector investment by providing various fiscal and financial incentives such as Accelerated Depreciation benefit; concessional custom duty exemption on certain components of wind electric generators. Besides, Generation Based Incentive (GBI) Scheme was available for the wind projects commissioned before 31 March 2017.
