Indian wind energy sector has been developing into the main stream of industrial activity with active participation of the private sector. About nine wind turbine manufacturers/suppliers with foreign collaborations either as joint ventures or with technology transfer arrangements are installing wind turbines in India. These manufacturers/suppliers, with a few exceptions, are normally supplying wind turbines of the types provided by their principals, which are certified by accredited certification bodies. However, these certificates are issued based on the European site conditions and approval schemes/technical criteria of the country in which they are carried out. In addition, the turbines installed in India undergo major/minor changes to suit Indian conditions. All the major stakeholders expressed the need for establishing the certification facility in India. Accordingly, Ministry of New and Renewable Energy (MNRE) has established Standards and Certification (S&C) Unit of NIWE with the technical support and partial financial assistance from DANIDA, Denmark. RISO National Laboratory, Denmark acted as Technical Consultants to establish the Certification expertise in India.
TAPS-2000 (amended), the Indian certification scheme for wind turbines, has been prepared by the unit in line with International Standards, while taking into account of the Indian conditions. The scheme was approved and issued by MNRE.
According to TAPS-2000 (amended), the Provisional Type Certification (PTC) of wind turbines can be carried out according to the following three categories:
Category-I : PTC for wind turbine already possessing type certificate or approval.
Category-II :PTC for wind turbine already possessing type certificate or approval, with minor modifications/ changes, including provisional type testing/measurements at the test site of NIWE/Field.
Category-III : PTC for new or significantly modified wind turbine including provisional type testing/measurements at the test site of NIWE / Field.
Revised List of Models and Manufacturers of Wind Turbines
R&D unit focuses on time-bound, mission oriented research and development programme to achieve and maintain world class reliable and cost effective technology in wind energy system. The unit continues to improve its knowledge and skills through continuous learning to keep pace with state-of-the-art technology and excel through effective networking approaches. The unit carries out in-house R&D and networking in the research and development will be the approach the most of the project. Interaction meeting through R&D institutions, manufacturers, and designers are envisaged as necessary and essential. Strategic collaboration that would assist in the most suitable technological development for the country is nurtured. For the 12th Five Year Plan the R&D activities of NIWE are classified into following thrust areas.
Also, the R&D unit conducts research relevant studies with an objective to improve the performance of the existing wind turbines together with advancement in wind turbine technology.
