MNRE Amends RLMM To Promote Domestic Manufacturing, Cybersecurity
The Ministry New and Renewable Energy (MNRE) on 31 July 2025 issued amendments to its earlier Revised List of Models and Manufacturers of Wind Turbines (RLMM) from 2018 for the purpose of strengthening quality control, enhancing cybersecurity and promoting domestic wind manufacturing.
Under the new amendments, the RLMM has been renamed as Approved List of Models and Manufacturers (Wind) i.e ALMM (Wind). It also makes the use of major wind turbine components in the manufacturing of listed wind turbines such as Blade, Tower, Gearbox, Generator and Special Bearings (Main, Pitch and Yaw Bearing) mandatory from the Approved List of Models and Manufacturers (Wind Turbine Components) i.e ALMM (Wind Turbine Components).
Furthermore, the amendment stresses that the Wind Turbine R&D Centre, data centre and servers must be mandatorily located in India.
The amendment, however, will not be applicable to projects that are already bid as well as captive or open access, commercial or industrial, or third party sale projects that are to be commissioned within 18 months from the date of issuance of the amendment. New wind turbine manufacturers and models with a total capacity of 800 MW too have been exempted from the mandatory use of ALMM (Wind Turbine Components) for a period of two years. The purpose here is to promote new innovative and efficient technologies that may not be available locally.
In a press release, MNRE said the RLMM was a mechanism to ensure quality and reliability of wind turbines installed in the country, for protecting the consumer interests, while ensuring larger energy security of the country. The mechanism was one of the enablers towards promoting domestic wind turbine manufacturing industry in the country, which currently crossed the 20 GW annual manufacturing capacity. These amendments, the press release said, will boost the existing quality control mechanism including the cyber security aspects along with boosting domestic manufacturing in wind sector.
