Wind Turbines Parts only from Listed Manufactures

· MNRE Issues Amendment to RLMM Procedure for Wind Turbines regarding Mandatory Use of Major Wind Turbine Components from Listed Manufacturers

· RLMM Renamed as ALMM (Wind); Amendment aims to Strengthen Quality Control, Enhance Cybersecurity, and Promote Domestic Wind Manufacturing

RLMM Renamed to ALMM (Wind)

The existing Revised List of Models and Manufacturers (RLMM) is now renamed as the Approved List of Models and Manufacturers (Wind) or ALMM (Wind).

Mandatory Use of Approved Components

· Wind turbine manufacturers must now use approved components listed under a new list:
ALMM (Wind Turbine Components), which will be issued separately.

· Major components covered:

o Blade

o Tower

o Gearbox

o Generator

o Special Bearings (Main, Pitch, and Yaw)

Cybersecurity & Localization

· Wind turbine R&D centres, data centres, and/or servers must now be located within India to enhance cybersecurity infrastructure.

Exemptions

1. Already-bidded projects and Captive/Open Access/C&I/Third-Party Sale projects
→ Exempt if commissioned within 18 months of this amendment.

2. New manufacturers or turbine models
→ Exempt from component ALMM requirement for up to 800 MW capacity for 2 years
→ Encourages new technologies and innovations not available domestically.

Impact & Objective

· Strengthens quality assurance and cybersecurity.

· Promotes Make in India by boosting domestic wind turbine manufacturing.

· Supports the sector’s growth, with current domestic capacity exceeding 20 GW annually.

<Amendment dated 31.07.2025>

[ABS News Service01.08.2025]

Ministry of New & Renewable Energy (MNRE) had earlier issued ‘Procedure to apply for inclusion of a Wind Turbine Model in the Revised List of Models and Manufacturers of Wind Turbines (RLMM)’ vide OM of even number dated 01.11.2018.

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.

Through this amendment, the RLMM has been renamed as Approved List of Models and Manufacturers (Wind) i.e ALMM (Wind). Further, it is now mandatory for use of major wind turbine components such as Blade, Tower, Gearbox, Generator and Special Bearings (Main, Pitch and Yaw Bearing) from the Approved List of Models and Manufacturers (Wind Turbine Components) i.e ALMM (Wind Turbine Components) in the manufacturing of listed wind turbines. The ALMM (Wind Turbine Components) list will be issued by the Ministry separately. The amendment also includes mandatorily locating Wind Turbine R&D Centre, Data Centre and/or Servers within India to strengthen the cybersecurity ecosystem.

This amendment will not be applicable on the already bided wind projects and Captive/Open Access/C&I/Third Party sale projects to be commissioned within 18 months from date of issuance of the amendment. In addition, new wind turbine manufacturer and / or new wind turbine models will be exempted from mandatory use of components listed in ALMM (Wind Turbine Components) for a total capacity of 800 MW for a period of two years to promote the new technologies having new innovation & performance efficiency not available indigenously.

This step will boost the existing quality control mechanism including the cyber security aspects along with boosting domestic manufacturing in wind sector.
