The hidden costs EPCs leave out of the per-MW quote

The headline price is not the project cost. Here’s what gets added later.

A “₹3.5 crore per MW” quote sounds complete — until the invoices for everything it excluded start arriving. EPCs compete on the headline number, so the safest way to win a bid is to quietly leave costs out of scope. Here is what owners routinely get billed for after signing.

01

Power evacuation — often the biggest surprise

The transmission line from your plant to the substation, the bay extension at the substation, and GETCO connectivity charges are frequently excluded. A line can run ₹20–27 lakh per km, and at a few km that is a material number nowhere in the headline quote.

02

Land development & statutory costs

Land levelling, boundary, internal roads, water and the NA-conversion premium, GEDA/registration fees, bank guarantees and Interest During Construction (IDC) are usually the owner’s scope — not the EPC’s.

03

GST and the DCR premium

Confirm whether the quote is inclusive of GST, and whether it assumes cheaper non-DCR modules. If your scheme mandates domestic (DCR) modules, that alone can add roughly ₹0.8–1.0 crore per MW — and ALMM List-II for cells applies from June 2026.

Frequently Asked Questions

Commonly the transmission line and bay extension, GETCO connectivity charges, land development, NA premium, statutory fees, bank guarantees, IDC and sometimes GST. Always get the scope in writing and a line-item exclusions list.
