Technology Development and Manufacturing Base for Wind Power

The Wind Turbine Generator technology has evolved and state-of-the-art technologies are available in the country for the manufacture of wind turbines. Around 70-80% indigenisation 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 44 different models of wind turbines are being manufactured by more than 17 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.  

Revised List of Models & Manufacturers (RLMM)

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. The timelines for processing of RLMM applications are:

i. Online application for RLMM Registration by OE Ms - Last date 7th of every month (Soft copy through email and Physical Copy);

ii.  Review by MNRE- Written communication to the OEMs of any shortcomings/gaps by 30th of every month;

iii.  Replies to be filed with MNRE by OE Ms by 10th of the following month;

iv.  RLMM Committee to meet on 15th of every month and if 15th is a holiday, it will be held on the following working day; and 

v.    RLMM list to be updated by 25th of every month.

Concessional Custom Duty Certificates (CCDCs)

In order to encourage the manufacturing of Wind Turbine Generators(WTG) in India, Government is providing financial incentive in the form of Concessional Custom Duty Exemption on some of the critical components required to be imported for manufacturing of WTG.

The components eligible and the conditions for availing such benefits are outlined in the notificationno- 50/2017- dated 30.06.2017 of MOF.Wind Turbine Generators/ Models which are included in the RLLM list of MNRE for OEM and component Manufacturers, whose Bill of Material (indicating the drawing no, quantity required and supplier for the part/ raw materials) is accepted by the Ministry, are only eligible for Concessional Custom Duty Certificates (CCDCs).

The procedure for availing CCDC is given as under.


1.     The applicants are required to submit the application in the prescribedformat.

2.     The following documents are required to be enclosed.

a)  Commercial Invoice issued by the supplier in the name of Importer.

b)  Bill of lading.
