MNRE Renames RLMM, Tightens Wind Turbine Rules
01 Aug 2025 CW Team
The Ministry of New & Renewable Energy (MNRE) has amended the framework for regulating wind turbines by renaming the existing Revised List of Models and Manufacturers (RLMM) to the Approved List of Models and Manufacturers (Wind), or ALMM (Wind).
Originally introduced in November 2018, the RLMM was designed to ensure the quality and reliability of wind turbines installed across India, aiming to safeguard consumer interests and support the country's energy security. The initiative has played a key role in supporting India’s wind turbine manufacturing industry, which has now surpassed an annual capacity of 20 GW.
Under the new amendment, it will be mandatory to use major wind turbine components — including blades, towers, gearboxes, generators and specialised bearings (main, pitch and yaw) — only from manufacturers listed in a newly introduced ALMM (Wind Turbine Components). This separate list will be issued by the MNRE. Additionally, manufacturers must locate their Wind Turbine R&D Centres, Data Centres, and/or servers within India, in a move aimed at strengthening the cybersecurity ecosystem.
However, this new policy will not apply to already auctioned wind projects, or Captive/Open Access/Commercial & Industrial (C&I)/Third Party sale projects scheduled for commissioning within 18 months of the amendment's publication. Furthermore, new manufacturers or turbine models will be granted a temporary exemption from the mandatory use of ALMM-listed components — up to a total capacity of 800 MW over two years — to encourage innovation and efficiency improvements not yet available from domestic sources.
The move is expected to reinforce India’s quality assurance mechanisms, bolster cybersecurity, and further promote indigenous wind turbine manufacturing.
