On August 1, 2025, India’s Ministry of New and Renewable Energy (MNRE) issued a landmark notification tightening rules for wind-turbine makers. Beyond mandating domestic sourcing and data localization, the ministry formally renamed its quality‐control registry for wind turbines—previously the Revised List of Models and Manufacturers (RLMM)—to the Approved List of Models and Manufacturers (Wind), or ALMM (Wind).
Key Elements of the New Order
- Mandatory Use of ALMM (Wind) Components
Major subassemblies—blades, towers, gearboxes, generators, and special bearings (main, pitch, yaw)—must now come from manufacturers listed on the new ALMM (Wind Turbine Components) registry. A technical team will inspect each vendor’s production site before they are added to the list. - Data Localization & R&D Presence
All real-time turbine performance and operational data must be stored on servers located in India. Turbine OEMs are required to set up their R&D centres, data centres, and servers domestically within one year of the notification. - Exemptions & Caps
Projects already bid out or due for commissioning within 18 months are exempted. New wind-turbine models and manufacturers can receive waivers—capped at 800 MW of cumulative capacity over two years—to encourage innovative technologies not yet available domestically.
By channeling procurement toward ALMM-certified vendors, the MNRE is set to turbocharge India’s wind-turbine manufacturing ecosystem—scaling domestic production from 20 GW per year and strengthening every link in the supply chain to curb reliance on imports. At the same time, the requirement to localize all performance and operational data fortifies cybersecurity by keeping critical grid-management information within Indian jurisdiction, reducing exposure to external cyber threats. Finally, the consolidation of approved models and manufacturers under a single ALMM (Wind) registry streamlines the procurement process for developers, financiers, and regulators alike, bolstering confidence in both the quality and reliability of newly installed turbines.
Industry Winners & Challenges
- Domestic OEMs Gain: Suzlon Energy, Inox Wind, Adani Wind, and Bharat Forge are positioned to capture the bulk of new component orders as ALMM-approved suppliers.
- Foreign Firms Adapt or Exit: Global players like Envision (China) must either localize manufacturing and data functions or partner with Indian entities to comply; otherwise, they risk losing market share.
- Implementation Hurdles: MNRE will need to process vendor inspections, publish the ALMM (Wind) list promptly, and coordinate with state regulators to avoid project delays during this transition.
India’s updated wind-turbine regime—combining local-sourcing mandates, data-sovereignty rules, and a rebranded ALMM—signals a new chapter in the country’s clean-energy strategy. If implemented smoothly, these measures could not only double domestic manufacturing capacity over the next five years but also cement India’s position as a resilient, self-reliant wind-turbine market.
