ALMM & Domestic Content Requirements

Understanding the implications of the Approved List of Models and Manufacturers (ALMM) on utility-scale solar EPC procurement timelines.

SECTOR: BESS & Utility Power Infrastructure

The Ministry of New and Renewable Energy (MNRE) mandate regarding the Approved List of Models and Manufacturers (ALMM) fundamentally alters the procurement landscape for utility-scale solar projects in India. This whitepaper discusses strategic adjustments necessary for compliance.

Supply Chain Constraints and Mitigation

The restriction to domestically manufactured modules temporarily tightens supply chain availability. Developers must secure procurement contracts significantly earlier in the project lifecycle. We recommend exploring strategic partnerships and volume commitments with Tier-1 domestic manufacturers to ensure timely delivery and avoid costly delays.

Module Efficiency Impacts

While domestic manufacturing capacity is growing, the transition to high-efficiency N-type TOPCon or HJT cells is still maturing locally. EPCs must carefully evaluate the real-world performance of available ALMM-listed modules and adjust their Balance of System (BOS) designs—such as tracker spacing and DC-coupled storage integration—to compensate for potential variances in yield.

Economic Modeling for PPAs

The premium associated with domestic content must be accurately factored into financial models. We analyze the impact on Levelized Cost of Energy (LCOE) and the corresponding adjustments required in Power Purchase Agreement (PPA) bidding strategies to maintain project viability under the ALMM framework.
