What is being procured: the work, supplies or services, deliverables and quantities, locations, phases, completion or delivery timelines, applicable standards, and notable exclusions.
Single-point-responsibility EPC for Great Nicobar Island Gas Engine Power Project (108 MW ±5 MW) near Galathea Bay, GNI — Design, Engineering, Manufacture, Supply, Civil/Structural/Architectural works, Erection, Testing, Commissioning and PG tests.
After amendments, offer 9 to 24 RLNG-fired gensets to deliver net plant capacity 108 ±5 MW, with phased installation and a small-engine subset for early transportability.
Employer supplies RLNG at an in-plant tap-off; electrical terminal is 132 kV & 33 kV line take-off gantries; exclusions are evacuation lines beyond SLD terminals, PLCC/HF/communication beyond FO terminal equipment, and RLNG supply.
Packing, ocean/inland transport, customs/port clearance and port charges are in bidder scope; Amendment Gen-19 also puts any temporary jetty/connecting-road infrastructure needed to reach site in bidder scope.
Engines to ISO 3046 and OEM proven practice; NOx statutory/guarantee level tightened by addendum to <75 ppm (dry, 15% O2); seismic Zone V and high wind design basis apply.
The complete checklist of documents to submit — mandatory vs conditional, with any prescribed formats, proformas or annexures — plus how to submit: portal and mode, envelope/cover structure, digital signature requirements, signing and attestation rules, and physical originals with their deadline.
e-tender only on GePNIC (https://eprocurentpc.nic.in/) on Single Stage Two Envelope basis; no hard-copy bidding documents and bids only on the portal.
Only if bid security (other than BG) is physical: original instrument in a separate sealed envelope, plus portal copy; BGs themselves must be e-BG (no physical BG).
IFB repeatedly requires undertakings/certificates 'as per the format enclosed in the bidding documents', but ITB/Forms & Procedures volumes are not included among the downloaded files here — only IFB, Section-VI tech specs/addendum and BOQ are present.
Every corrigendum/addendum in order — what changed (original vs amended value), its impact, and the action for the bidder — ending with the values that finally apply.
tender-metadata lists no corrigenda; the only amendment file present is ADDENDUM-SEC-VI (technical clarifications + amendments). Key IFB dates therefore remain as published on 06.08.2026.
Addendum comprises (A) Clarification to Bidder Queries (pp.1–33 of that section), (B) Amendments to Technical Specifications Section VI (pp.1–36), and (C) Annexures to Amendments.
Engine count changed from 10–24 (Part A) / 11–24 (Part B M1) to 9–24; the early small identical pair capacity changed from 12 ±3 MW to 8.5–12 MW; 100-Ton transport limit clarified to allow dismantled condition.
Guaranteed/statutory NOx changed from less than 80 ppm to less than 75 ppm (dry volume, 15% excess O2) across stated load points.
Hydrogen 20–25% compatibility shop demonstration changed from all engines to one engine of each offered capacity (1 or 2 tests).
Vol-V 1.02.03 rewritten: contractor must modify/replace at no extra cost and re-test; 90-day (or Employer-allowed) cure remains; Employer delay excluded from LD imposition timing.
Transport clause expressly places temporary jetty/connecting road and other infrastructure needed to move engines/materials to project location in bidder scope, in addition to customs/port clearance.
Sea-water pumps/outfall diffuser route deleted; replaced by RO reject evaporator system and evaporation pond; surplus no longer discharged to sea under the amended terminal-point wording.
Final technical baselines: 108 ±5 MW net with 9–24 engines; phasing 2029/2030/2031/2032 unchanged; small pair 8.5–12 MW and ≤100 T transport; NOx <75 ppm; H2 shop test per capacity type; bidder logistics including temporary jetty/road; ZLD via evaporator; IFB commercial dates and INR 20 Cr / USD 2,076,500 bid security unchanged in this pack.
Genuine conflicts within and across the documents (original vs corrigenda, clause vs annexure, tender document vs BOQ): both sides with citations, and which value prevails.
IFB, BOQ and Addendum use CS-6401-001A-2, while Technical Specification Part A/B covers print CS-6401-001-2. Treat CS-6401-001A-2 as the tender/package identity used on the IFB and addendum.
Part A/IFB originally stated 10–24 engines; Part-B M1 stated 11–24; Addendum Gen-06/07/08/09/10 finally set 9–24. Final value: 9 to 24 engines.
IFB brief scope and original Vol-V statutory guarantee say <80 ppm; Amendments Gen-03/04 change technical guarantee/statutory NOx to <75 ppm. Final technical requirement: <75 ppm.
Original project information required max two identical gensets cumulatively 12 ±3 MW; Gen-07/08 amend to 8.5 MW to 12 MW. Final: 8.5–12 MW cumulative for the special pair.
Original terminal point allowed surplus/overflow from Solar Pond to sea; WS-05 replaces this with evaporation pond + RO reject evaporator and internal use of permeate. Final: no sea discharge path under amended Cl. 26.00.00(ii).
Only critical, tender-specific pre-bid queries that could materially change bid/no-bid, pricing, eligibility or contractual risk. Skip generic or obvious questions the documents already answer clearly.
Ask NTPC/GePNIC support to confirm download of ITB, GCC/SCC, Forms & Procedures and any SCC time-for-completion / CPG / payment schedules — they are referenced but absent from this document set.
After Gen-19 puts temporary jetty and connecting road in bidder scope, seek bathymetry, permissible temporary works locations, environmental/CRZ constraints, load ratings and whether Owner facilitates statutory permits.
Clarify mobilization milestone: exact date/condition of Owner-finished levelling, fencing and major tree clearance versus bidder’s residual <30 cm cutting and package civil start.
Lock a RACI matrix for forest/wildlife/PVTG, chimney height, CTE/CTO and other clearances, including which are condition precedent to LOA/mobilization and whether Employer delay gives time/cost relief.
Seek explicit linkage of phase-wise COD, PG tests, LD for delay per phase, storage/preservation of later engines, and whether Contract Price is one EPC lump with deferred installation cash flow.
Confirm acceptable H2 blend test protocol, measurement method, pass/fail criteria, and whether tests may be at OEM works without full plant systems.
Commercial, legal and execution risks a bidder should weigh: liquidated damages and penalties, unusual or one-sided clauses, tight timelines, and payment or security risks.
All transport to Great Nicobar, including temporary jetty/connecting road if needed, is bidder risk/cost — a dominant commercial and schedule risk for heavy gensets/GIS transformers.
Per-genset output/heat-rate LDs can run concurrently up to 25% of Contract Price; beyond -2.5% output or +2% heat rate Employer may reject equipment and recover payments; Category II/III failures can also lead to rejection after 90 days.
Capacity is staged across 2029–2032, creating multi-year preservation, remobilization, warranty start and cash-flow risks on a single EPC package.
Seismic Zone V, high wind (44 m/s; min 1500 N/m²), cyclone/tsunami exposure and reliance on amendment geotech annexure / nearest-island climate data create foundation and derating risk.
Addendum deletes sea outfall works and mandates RO reject evaporator + evaporation pond path — process performance and power/chemical opex risk sits with bidder under ZLD compliance.
INR 20 crore / USD 2.0765 million bid security is immediately at stake, while performance security, delay LD and payment terms are not visible in the available files — underwriting risk until full GCC/SCC are reviewed.
Mandatory 20–25% H2-by-volume compatibility with shop demonstration (per capacity type) was not relaxed despite OEM objections — technical qualification and test-cost risk remains.
The inviting authority and relevant contacts: office, person, designation, address, phone and email — and which address receives physical submissions, if any.
NTPC Limited, Corporate Contracts, Engineering Office Complex, Noida — contacts for this IFB.
NTPC Limited registered office is NTPC Bhawan, SCOPE Complex, 7, Institutional Area, Lodi Road, New Delhi – 110003 (CIN L40101DL1975GOI007966).
Bids are online-only; the only physical item expressly required by IFB is a non-BG bid-security instrument in a separate sealed envelope — IFB gives the Noida EOC communication address but does not separately restate a distinct physical receiving desk/deadline beyond bid accompaniment.
