The Ministry of New and Renewable Energy (MNRE), Government of India, has issued a draft notification proposing amendments to the procedure for including and updating wind turbine models in the Revised List of Models and Manufacturers (RLMM).

The draft has been circulated for public consultation, and stakeholders have been invited to submit their comments within three weeks. Under the proposed amendments, MNRE aims to streamline and expand the technical information required from wind turbine manufacturers.

As per the revised format, companies will now need to provide detailed model specifications, including hub height (HH), rotor diameter (RD), tower type, and rated power.Additionally, manufacturers must disclose type certificate and IS/ISO certification details along with their validity, as well as information about technical collaborations.

The updated clause also requires sharing details of domestic sourcing of critical components such as blades, towers, gearboxes, and generators. A major highlight of the amendment is the emphasis on domestic manufacturing. The draft mandates that wind turbine models submitted for inclusion in the RLMM must have their type certificate reflect that key components viz.blades, towers, gearboxes, and generators, are manufactured within India.To ease the transition for new players, the MNRE has proposed a temporary exemption allowing imports for up to 50 turbines or 200 MW (whichever is lower) for a period of one year from the date of RLMM inclusion.

Furthermore, the localisation requirement for gearboxes and generators will become mandatory six months after the new rules come into effect. In line with national priorities on data security, MNRE has introduced a new clause to enforce cybersecurity protocols within the wind energy sector. The proposed rules mandate that all operational data must be stored within India, and data transfer in real-time outside the country is strictly prohibited.

Manufacturers will also be required to maintain operational control centers exclusively within India. Another important condition is the establishment of R&D centers in India within six months from the date of notification. To improve transparency and ease of access, the ministry has asked applicants to submit all required documents in soft copy format. All industry stakeholders, including wind turbine manufacturers, project developers, and certification bodies, are encouraged to provide feedback on the draft.
