Research Methodology

Bottom-up industrial offtake modeling reconciled against top-down module manufacturing capacity tracking forms the analytical core. Primary interviews with utility planning officers, IPP project developers, EPC contractors, and grid operators were validated against secondary sources including IEA renewable deployment databases, CEA regulatory filings, and SREDA tariff notifications. Cross-referencing Bangladeshi textile procurement disclosures with Gujarat solar park interconnection queues enabled demand-supply reconciliation.

Historical capacity addition trendlines across solar, wind, and biomass segments informed projection elasticity parameters. Segmentation modeling spanned technology type, generation capacity tier, project scale, regulatory framework, and regional grid type. CAGRs were derived from installer shipment data triangulated against tender award volumes and commercial operation date announcements. Hydrogen hub feedstock demand and PLI scheme utilization rates served as industry-specific forecast inputs.

Regulatory revision, polysilicon supply disruption, and currency volatility are the dominant revision risks. Decision-makers should treat outputs as directional within the stated assumption set.
