MNRE Issues Revised Norms Of Wind Turbine Prototypes

The Ministry of New and Renewable Energy (MNRE) has released revised guidelines for the installation of prototype wind turbine models, aiming to strengthen testing and certification mechanisms while curbing the proliferation of uncertified systems.

Effective from June 12, 2023, the new framework mandates that all wind turbine manufacturers seeking to deploy prototypes must obtain type certification from internationally accredited agencies. The updated rules are expected to ensure higher safety standards and technical compliance for wind energy infrastructure in the country.

Under the guidelines, the National Institute of Wind Energy (NIWE), Chennai, will act as the nodal authority for implementation. Manufacturers are required to submit documentation in a prescribed format to NIWE, which will recommend approval for prototype testing and synchronization with the grid.

Each prototype turbine will be limited to a maximum of three installations for commissioning, with land allocation based on physical footprint. Grid synchronization must occur within 18 months of NIWE’s recommendation letter, which is valid for three years. Testing and certification must be completed within four years of the recommendation date.

The guidelines strictly prohibit the use of second-hand components in prototype turbines and ban serial production unless the model is listed in the Revised List of Models and Manufacturers of Wind Turbines (RLMM). Ownership must remain with the original manufacturer, and resale is barred unless RLMM inclusion is secured.

Additional conditions include:

* Prototype certificates are valid for up to three years, with provisions for extension.

* Compliance with standards such as IECRE OD 501 and IEC 61400-22:2010 is mandatory.

* Regular maintenance is compulsory; failure may result in grid disconnection.

* An affidavit and indemnity bond must be submitted to relevant authorities.

The MNRE said the revised norms reflect India’s efforts to create a controlled testing environment for wind technologies, ensuring only certified models move forward to commercial deployment.
