India extends ALMM wafer rule to deepen domestic solar supply chain

The MNRE notice creates ALMM List-III for wafers and links approved wafer manufacturing to equivalent ingot capacity. Once the rule takes effect, new qualifying solar projects will need to use wafers from approved domestic manufacturers, with grandfathering provisions for projects already in the pipeline. The framework matters because India has built large module and cell capacity but still needs deeper supply-chain localization in wafers and ingots. For developers and manufacturers, the 2028 deadline gives a policy signal for upstream investment while leaving time for domestic capacity to scale.
