MNRE Expands ALMM Framework to Include Solar Wafers and Ingots from June 2028

The Ministry of New and Renewable Energy has broadened its Approved List of Models and Manufacturers (ALMM) framework by introducing a new List-III covering solar ingots and wafers. The mandate will come into force from June 1, 2028, aiming to strengthen domestic manufacturing and reduce import dependence.

The Ministry of New and Renewable Energy (MNRE) has announced an expansion of its ALMM regulations to include upstream solar components such as ingots and wafers. This move extends existing sourcing requirements—already applicable to solar modules and cells—further along the value chain, targeting segments where India currently relies heavily on imports.

Union Minister Pralhad Joshi described the development as a significant step toward strengthening India’s solar manufacturing ecosystem. He highlighted that the measure is expected to promote domestic production, improve supply chain resilience, and ensure better quality standards across the industry.

As per the new guidelines, all applicable solar projects—including net metering and open access installations—will be required to use wafers listed under ALMM from June 1, 2028. To ensure a smooth transition, the policy includes grandfathering provisions for projects that are already under development.

The framework also defines a cut-off timeline linked to the release of the initial ALMM List-III. Bids submitted under the Section 63 route after seven days from the publication of this list must comply with the requirement to use ALMM-approved wafers.

Importantly, the first ALMM List-III will only be issued once at least three independent wafer manufacturers, not under common ownership, are enlisted with a combined capacity of 15 GW. Additionally, eligible manufacturers must also have corresponding ingot production capacity, encouraging deeper integration within the domestic supply chain.

From the effective date, stricter compliance norms will apply to ALMM List-I for solar modules, allowing only those modules that incorporate ALMM-approved cells and wafers. Separate provisions will remain in place for grandfathered projects to ensure continuity and clarity during implementation. The amendment also maintains existing Domestic Content Requirement (DCR) rules without any dilution.

Wafers play a crucial role in the solar manufacturing process, acting as the intermediate stage between polysilicon and solar cells. With limited domestic production capacity at present, India has been largely dependent on imports for this component.

The introduction of ALMM List-III is expected to drive fresh investments in ingot and wafer manufacturing, enhance supply chain security, and reduce exposure to global disruptions. It is also likely to improve traceability and quality assurance across the solar value chain while generating skilled employment opportunities in upstream manufacturing segments.
