MNRE has updated its wind turbine approval system, renaming the Revised List of Models and Manufacturers (RLMM) to the Approved List of Models and Manufacturers (Wind) or ALMM (Wind).
- The RLMM 2018 was a mechanism to ensure quality and reliability of wind turbines installed in the country
Key features of ALMM Wind
- Domestic Supply Chains: Mandatory sourcing of key components (blades, towers, gearboxes, generators, special bearings) from approved Indian suppliers.
- Data Localisation: All operational data must be stored within India. Operational control centres must also be in India.
- R&D Centres: To be set up by manufacturers within a year to design turbines for Indian conditions.
- Quality Standards: From Sept 2026, BIS certification required for all components.
- Exemptions:
- Already-bid projects or captive/open access projects within 18 months
- New manufacturers/models exempt for 800 MW over 2 years to promote innovation.
About India’s Wind Energy Sector
- India currently ranks 4th in the world for installed wind power capacity.
- Wind contributing 4.69% to total electricity generation.
- Installed capacity increased from ~21 GW in 2014 to 51.3 GW by June 2025
- Wind potential of the country is 1164 GW at 150 meters above ground level (National Institute of Wind Energy)
- India aims to cater 10% of global wind energy equipment demand by 2030.
