What are ALMM (Wind) and ALMM (WTC)?

The Ministry of New and Renewable Energy (MNRE) has introduced a regulatory framework- ALMM (Approved List of Models and Manufacturers), to confirm that only high-quality and verified products are being used in India’s renewable energy projects. ALMM has now stretched its limits to the wind energy sector; earlier, it was introduced for photovoltaic (PV) modules and cells. A step taken to reinforce India’s promise of safety, quality, and reliable clean energy infrastructure.

What is ALMM (Wind)?

ALMM (Wind) refers to the enlistment of complete wind turbine (WT) systems that satisfy MNRE’s prescribed technical and performance requirements. This covers all the significant components included in a functioning turbine, such as:

• Nacelle
• Rotor blades
• Hub
• Tower
• Control systems

Only manufacturers are eligible to supply equipment whose turbine models are mentioned under ALMM (Wind) for all the supported wind projects. This also includes manufacturers who are receiving subsidies or participating in public tenders.

What is ALMM (WTC)?

ALMM (WTC) refers to the enlistment of individual wind turbine components (WTC) that are essential to system performance and safety. The equipment that falls under this component are:

• Gearboxes
• Generators
• Controllers
• Yaw and pitch systems
• Power converters

The Ministry of New and Renewable Energy (MNRE) ensures that the turbine building blocks must meet the quality standards strictly by extending ALMM to components. This has helped in minimising the risk of technical failure and improving the project’s long-term profitability.

Why is ALMM important?

The ALMM (Approved List of Models and Manufacturers) framework plays a vital role in:

• Preventing unreliable imports and unverified technologies from reaching the Indian market.
• Aligning with international standards by promoting domestic production.
• To ensure dependability and consistency throughout wind energy installations.
• It helps in boosting the investors’ confidence through transparent and accountable spending.

Why MNRE ALMM Introduced the SOP:

The supply chain of India got complicated as soon as the wind energy sector expanded rapidly. Until now, a number of regulatory and operational challenges have resulted from the absence of a regulated framework for permitting wind turbines. After recognizing all these gaps, the Ministry of New and Renewable Energy (MNRE) launched an elaborate SOP (Standard Operating Procedure) for the ALMM (WTC and Wind) enlistment process.

Key Issues faced before the SOP was introduced:

• Lack of standardized approval process: There was no uniform process for evaluating and clearing wind turbine models and components, which was leading to inconsistencies and delays in manufacturer enlistment.
• Irregular documentation: Lack of systematic documentation led the manufacturers to struggle with submission requirements.
• Delay in projects: Due to a lack of transparency, it prolonged the whole approval timeline.
• Irregular imports or substandard components: As cheap, quality components stepped into the market, they hampered the project’s reliability. The parts failed to meet the performance expectations and caused frequent breakdowns, increased maintenance costs, and safety risks.
• Compliance risks: Loopholes created due to the absence of standardized testing and verification.

Other problems faced by the manufacturers are unclear timelines and different perspectives on technical standards. This not only delayed the execution of the project but also prevented new entrants from participating in the market.

Particularly for the government-backed projects where responsibility and quality are crucial, such shortcomings can result in project delays, compliance risk, and cost overruns.
