Clean energy manufacturing in India has reached the point where domestic demand and export economics pull in the same direction. Module and cell capacity, electrolysers, battery packs and the balance of system components all now have a credible Indian case. The incentives are real, but they reward a specific kind of operator.

Two schemes doing different jobs

PLI is a production subsidy tied to committed capacity and measured output. It improves the economics of building at scale and penalises hesitancy, because the benefit is calculated against volumes you have already promised. RODTEP works on the export side, remitting embedded duties and levies that would otherwise sit inside your landed cost in a destination market. One improves the factory case, the other improves the export case, and most strong plans use both.

The demand picture

Domestic demand is no longer the swing factor it was. Utility scale procurement, rooftop programmes and open access industrial buyers now generate enough volume that a plant sized for India alone can be viable. What export access adds is the ability to run that plant at a utilisation rate the domestic season cannot guarantee on its own.

• Domestic content requirements in government linked procurement favour local manufacture and are tightening rather than loosening.

• Input duty structures change more often than plant economics, so the sensitivity analysis matters more than the base case.

• Land, evacuation infrastructure and water are state level decisions and vary widely in cost and speed.

Where projects slip

The two most common causes of delay are power evacuation and equipment import timing. Evacuation approvals sit with state utilities and are rarely parallelised properly. Equipment import timing is usually a classification problem, where tooling arrives under a code that attracts a duty nobody modelled. Both are avoidable with three months of preparation and expensive without it.

The question worth answering first

Before the plant design, the useful question is whether your product qualifies cleanly under the incentive definitions as they are written today, and what share of your bill of materials would have to be localised to keep qualifying as those definitions tighten. That analysis usually reorders the shortlist of states and partners, and it is far cheaper to run before the capital is committed.
