ALMM Wind Turbine List 2026: 30 Models, Validity and Rules

What ALMM-Wind Is

MNRE's July 31, 2025 office memorandum renamed the Revised List of Models and Manufacturers, known as the RLMM, as the Approved List of Models and Manufacturers for wind turbines, or ALMM (Wind). The list names the turbine models and manufacturers that meet India's type certification and quality assurance requirements. State nodal agencies, utilities, developers and lenders use it as the reference for which turbines can be installed. MNRE followed with a standard operating procedure on October 29, 2025 that sets out how manufacturers apply for listing.

The list is revised from time to time, and MNRE has published several dated versions in 2026. The latest reported version is dated August 20, 2026. It lists 30 models, with rated capacity, rotor diameter, hub height, tower type and type certification details for each.

Who Is on the List

Adani's four entries are two tower variants of a 5.2 MW series, built with W2E Wind to Energy of Germany, and two models developed with Windey of China. Many of the listed companies name an overseas technology partner, including firms in Germany, China, the United States, Denmark, Austria and Spain.

How the List Splits by Size

The list already carries several 5 MW class models. Suzlon's S175 and Inox's 4X platform, which are heading for deployment, do not appear in the entries reported so far.

Certificate Dates to Check

Each entry shows how long its type certificate is valid. Reading the August 20 version against today's date, several entries have already passed their listed validity, and more come due soon.

A passed date on the list does not by itself mean a turbine has lost its approval. A renewed certificate may be on file, and MNRE may have updated the list. It does mean the entry needs checking before it goes into a bid or a purchase order.

Some entries also carry limits that matter more than the headline rating. The Envision EN-156 certificate is restricted by a component certificate that expires on May 25, 2027, and Venwind Refex's and Senvion's larger models carry similar gearbox limits.

What Listing Does Not Mean

MNRE says the list was prepared from documents and information submitted by manufacturers. It advises users to verify the complete type approvals, certificate validity, manufacturing system certificates, technical specifications and power curves before relying on it. Inclusion is not certification and not a recommendation of a model for a particular project.

The entries also carry specific exclusions:

• Power boost modes can be excluded. Suzlon's 2,250 kW enhanced mode for the S120 is not considered, and Envision's 5,250 kW boost mode is excluded from ALMM-Wind.
• Altitude limits apply. The Suzlon S120 is listed to 1,000 metres above sea level, and the Envision EN-156 to 2,000 metres.
• Facilities can be carved out. Suzlon's hub and nacelle assembly facility in Pondicherry is excluded from its listing.
• Date conditions can sit on a model. For the GE 2.7-132, units manufactured before March 5, 2026 must have valid ALMM-Wind enlistment.

Rules Behind the List

The July 2025 memorandum did more than rename the list. Under it:

• MNRE publishes more detail on each listed model, including the sources of blades, towers, generators, gearboxes and special bearings.
• Turbine type certificates must name the facilities that make those components. MNRE plans a separate list of approved component makers, and only components from approved facilities will count for ALMM-Wind turbines.
• Turbine operating data and control systems must be hosted in India, with no real-time transfer of operating data abroad, and approved manufacturers must set up an R&D centre in India within a year.
• Transition relief applies. Projects whose bids closed before July 31, 2025 can defer the component rules if they commission within three years. Captive, open access, commercial and industrial, and third-party wind projects are exempt from the component stipulation if commissioned within 18 months. Newly listed manufacturers and models get a two-year exemption for up to 800 MW, with quarterly progress reports.

Check MNRE's memorandum and SOP for the exact wording before relying on a transition date.

What This Means for Wind and Hybrid EPCs

• Start the turbine choice from the list. Check the exact variant, meaning the rating, hub height and tower type, not just the model name.
• Read the validity date against the project clock. A certificate that lapses before commissioning is a schedule risk. SECI's Tranche-XXI tender, for example, ties the turbine rule to the list as it is updated up to the scheduled supply date. Our guide to the SECI Tranche-XXI wind tender covers how one central tender treats the turbine rule.
• Watch exclusions. Boost modes, altitude limits and carved-out facilities can change what a listed model can do on your site.
• Solar EPCs in hybrids follow the developer's turbine choice. The solar array and its layout still need to fit around the turbine, which our wind solar hybrid site guide covers.

Where Design Software Fits

On a hybrid site, the solar plan has to work around the turbine footprint and its access roads. Design software like Reslink produces the solar layout, bill of materials and single line diagram, and supports ground-mount feasibility up to 1 GW, so options can be compared early. It does not choose or verify turbines.

Frequently Asked Questions

Q1. What is ALMM-Wind?

MNRE's Approved List of Models and Manufacturers for wind turbines. It replaced the name RLMM in July 2025 and lists the turbine models and manufacturers that meet India's type certification and quality requirements.

Q2. How many turbine models are on the list?

The version dated August 20, 2026 lists 30 models from 16 manufacturers, rated from 225 kW to 5.3 MW.

Q3. Which is the largest listed turbine?

Venwind Refex's GWH182-5.3, rated at 5.3 MW, followed by Adani's 5.2 MW series and Envision's 5.0 MW model.

Q4. Does listing mean MNRE approves the turbine for my project?

No. MNRE says listing is not certification or a recommendation, and users must verify certificates, specifications and power curves themselves.

Q5. Can a listed turbine have an expired certificate?

The August 20 version shows five entries whose listed type certificate validity had passed by November 4, 2026. Check MNRE's current version and the manufacturer's current certificate before relying on any entry.

Q6. Who needs to use the list?

State nodal agencies, utilities, developers and lenders use it as a reference, and SECI's Tranche-XXI tender requires turbines from MNRE's approved list.

Q7. Do captive and open access wind projects have to meet the component rules?

Captive, open access, commercial and industrial, and third-party sale wind projects are exempt from the component sourcing stipulation if commissioned within 18 months of the July 31, 2025 notification.

Final takeaway

ALMM-Wind is a short list with moving parts: dated versions, certificate expiries and model-level limits. For wind and hybrid EPCs, the practical step is to check the exact variant and its validity date against the project schedule, and to treat the MNRE page as the source of record.
