India: local-content preference margin in NHPC Dibang Multipurpose Project main-dam tender (INR 17,069 crore)

Mechanism

The legal instrument is the Department for Promotion of Industry and Internal Trade's (DPIIT) Public Procurement (Preference to Make in India) Order, 2017 (as amended), which mandates a bid-evaluation preference margin for "Class-I local supplier" bidders across central-government and PSU procurement. NHPC Limited applied that standing order to the Lot-3 tender — main dam including coffer dam and hydro-mechanical works — for the Dibang Multipurpose Project (2,880 MW), a nationally strategic hydropower and flood-moderation scheme in Arunachal Pradesh sited close to the India-China border. GTA values the tender at INR 17,069 crore (~USD 2.05bn); a Lot-3 financial-bid finalisation reported in trade press in February 2026 put the winning (L1) bid at roughly INR 14,446 crore, consistent with GTA's figure being the pre-award estimated/reserve value rather than the awarded contract price.

This is the same recurring class of action as the large batch of NHAI/NHIDCL/state-PWD/NHPC localisation-preference filings already in the register, and the largest instance of that class filed to date by contract value. Severity is set at 3 (quant, anchored on the INR 17,069cr / ~USD 2.05bn tender value — roughly 5x the prior NHPC Kamala Hydroelectric filing and the single largest local-content-preference tender in the register), consistent with treating strategically sited, border-region hydropower civil works as a step above the routine NHAI-road baseline (capped at severity 2 regardless of size) while still reflecting a generic-order application rather than a new, bespoke trade instrument.

Downstream implications

• Foreign heavy-civil and hydro-mechanical contractors bidding into

one of India's largest active dam-construction packages face a structural scoring disadvantage relative to Class-I local suppliers, consistent with India's Atmanirbhar Bharat procurement posture extended into strategic, border-adjacent infrastructure.

• Another instance of the large recurring class of GTA-logged Indian

public-procurement localisation actions — individually routine in legal mechanism, but this instance is notable for scale and for sitting inside a project with independent strategic-infrastructure significance (largest dam under construction in India, Arunachal Pradesh border region).

Open questions

• The exact correspondence between GTA's INR 17,069cr valuation and

NHPC's specific NIT/tender ID for Lot-3 (candidates seen in secondary reporting include IDs in the 2024_NHPC_8xxxxx and 2025_NHPC_8xxxxx ranges) was not independently reconciled against NHPC's own tender portal during filing; GTA's full state-act detail sits behind an account-gated view.

• Exact local-content percentage margin and any exemption thresholds
