Centre extends ALMM framework to solar ingots and wafers

The Union Ministry of New and Renewable Energy (MNRE) has expanded the scope of the Approved List of Models and Manufacturers (ALMM) to include solar ingots and wafers, aiming to boost domestic manufacturing and reduce import dependence in the solar value chain.

A new ALMM List-III for ingots and wafers will come into effect from June 1, 2028, extending mandatory sourcing requirements—already applicable to solar modules and cells—further upstream to a segment currently dominated by imports.

Key Provisions

• All solar projects, including net metering and open access, must use ALMM-listed wafers from June 1, 2028.
• A cut-off date will apply to bids submitted under the Electricity Act, 2003 (Section 63), mandating the use of compliant wafers.
• The initial ALMM List-III will be notified only when at least three independent manufacturers with a combined capacity of 15 GW are operational.

Significance

Wafers are a crucial intermediate component in solar manufacturing, linking polysilicon to solar cells. At present, India has limited domestic wafer production capacity, making the sector vulnerable to global supply chain disruptions.

The move aligns with the government’s broader push for self-reliance under Atmanirbhar Bharat and supports India’s target of achieving 500 GW of non-fossil fuel capacity by 2030.
