Formation of SPV and signing of Concession Agreement: within 30 days of award of LOA.

Financials

Tender value or estimated cost, EMD/bid security (amount, acceptable forms, validity), tender document fees, performance security, and key payment terms.

Project commercial model (no construction-price BOQ)

DBFOT PPP: bidder finances the plant and bids the highest royalty per MT of waste over a Base Royalty of ₹50/MT; revenue is from sale of Bio-CNG and by-products, not a works contract payment.

Documents do not state a fixed estimated project cost/tender value figure in the RFP/CA text reviewed; Total Project Cost is defined as cost in Financing Agreements or as certified by Authority/IE, whichever is lower.
Financial Bid is a single BOQ line 'Royalty per MT of Waste' (item rate).
Highest Bidder = highest royalty per MT of waste.

Bid Security (EMD)

Bid Security Rs.7,50,000/- via RTGS or e-Bank Guarantee on https://tntenders.gov.in; refund timelines and forfeiture events are prescribed.

Refundable no later than 60 days after expiry of bid validity (including extension) or 60 days after LOA, whichever is earlier, except Selected Bidder whose security is retained until Performance Security is provided.

Authority provides land and guaranteed wet waste and names disposal point; Concessionaire bears design/finance/build/O&M, offtake marketing, utilities, permits, rejects transport and all taxes.

Authority has no role in identifying buyers, selling price or profit margin for Bio-CNG/manure.
No construction payment/tipping fee from Authority is provided in the payment article — Concessionaire pays Royalty/License Fee to Authority.

Required documents & submission

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.

Submission mode and portal

Bids only online through https://tntenders.gov.in; physical submission not permitted; server time is final.

Freeze Bid Submission on portal generates bid summary with bid no. and timestamp.
Late bids after server closing time are not recorded.
Modification allowed till closing time; withdrawal after submission not allowed.
Technical and Financial bids are separate (two-stage opening).

Language, signing and foreign-document attestation

Bid and correspondence in English; non-English/Tamil supports need notarized certified English translation; overseas documents notarized and apostilled/legalized.

Power of Attorney formats require execution per applicable law/charter documents; overseas PoA/MoU need Indian Embassy legalization and local notarization as noted in annexure notes.
Technical Bid must not contain Financial Bid information (responsiveness test).

Online covers / packages

Technical Bid package holds Annexures I–XII and qualification proofs plus Bid Security particulars; Financial Bid is the separate BOQ on the portal.

No hard-copy originals deadline is prescribed because physical submission is barred; instruments are portal RTGS/e-BG.

Corrigendum analysis

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.

No corrigendum / addendum in the tender pack

The downloaded document set contains no corrigendum or addendum file; original RFP/NIT/CA dates and conditions currently apply.

Bidders should still monitor https://tntenders.gov.in because Clause 2.9 allows addenda/corrigenda before Bid Due Date, and the NIT states amendments will be published only on the portal.
Finally applying values as of this pack: Issue 10.09.2026; Pre-bid 16.09.2026 11.30 AM; queries 10.10.2026; bid start 05.10.2026; Bid Due 12.10.2026 3.00 PM; opening 13.10.2026 3.30 PM; validity 180 days; Bid Security Rs.7,50,000; Performance Security Rs.1,50,00,000; Base Royalty ₹50/MT.

Contradictions

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.

Bid Due Date — Tamil NIT vs English NIT/RFP

Tamil notice text states last submission 05.10.2026 11.00 AM, while English NIT and Vellore RFP state 12.10.2026 3.00 PM.

Practical reading for this Vellore RFP: follow Clause 1.3 / cover schedule / English NIT (12.10.2026 3.00 PM).
Bidder should seek written clarification because the Tamil centralized advertisement is in the same pack.

Bid submission start time — cover vs Clause 1.3

Cover page says Bid Submission Start Date 05.10.2026 at 11.30 AM; Clause 1.3 says 05.10.2026 at 11.00 AM.

Portal server lock will control actual opening; seek clarification/addendum if start-time matters for internal filing.

Blacklisting declaration annexure number

Eligibility supporting-docs column cites Annexure IX for the blacklist declaration, but TOC, Clause 2.12 upload list and the printed form identify Annexure-XI (Annexure-IX is Exclusive MoU).

Submit the printed Annexure-XI blacklist declaration (and Annexure-IX MoU only if tech-partner route applies).

Portal URL spelling variants

Documents interchangeably cite tntenders.gov.in, tntender.gov.in and tn.tenders.gov.in.

Operative e-procurement portal named throughout the RFP operative clauses is https://tntenders.gov.in.

Pre-bid queries

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.

Confirm controlling Bid Due Date and submission start time

Ask Authority to confirm in writing that Bid Due Date is 12.10.2026 15:00 (not Tamil NIT 05.10.2026) and whether bid start is 11:00 or 11:30 on 05.10.2026.

Material to bid planning and to avoid portal lock-out / late-bid risk.

Site area, location map and existing site conditions

Request filled Schedule A map/inventory, exact land area (License Fee is per sq.m), access, utilities availability, geotech/waste characterization and any existing structures/encumbrances.

Schedule A currently has placeholders only; commercial design and License Fee cannot be finalized without area/site data.
CA disclaimer shifts site/subsoil/waste-characteristic risk to Concessionaire.

Waste supply shortfall / quality risk allocation

Seek clarity on remedies if Authority supplies below Guaranteed Acceptable Waste Quantity (80 TPD ±20%), exceeds 20% impurities, or delivers prohibited waste beyond prompt removal — especially impact on Royalty, KPIs and termination.

Authority must supply guaranteed quantity and limit impurities, but payment article still charges Royalty per MT delivered and KPI LDs can escalate to default; shortfall compensation is not expressly quantified in the extracts reviewed.

Financial Bid mechanics vs Base Royalty of ₹50

Confirm whether BOQ quote is absolute royalty (must be ≥ ₹50) or only the amount over-and-above ₹50, and how tie-break best-and-final offers will be taken on portal/sealed cover.

RFP says highest royalty over and above Base Royalty of ₹50/MT; BOQ line is simply 'Royalty per MT of Waste' with no base field shown in the sheet extract.

Offtake market assumptions and absence of tipping fee/VGF

Confirm there is no capital grant, VGF or tipping fee from Authority, and whether any offtake support/SATAT or similar facilitation is contemplated.

Entire recovery appears to be product sales minus royalty/license/opex/debt — critical to bid/no-bid and royalty ceiling.

Risks

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.

Full market / offtake revenue risk with escalating royalty outflow

No tipping fee; Concessionaire must market Bio-CNG and manure, yet pays Royalty from COD with 5% annual escalation, taxes on Royalty, and License Fee — downside revenue sits with bidder.

Royalty due by 10th of succeeding month; delay attracts Bank Rate + 3%.
Authority expressly has no role in buyers/price/margin.

Feedstock quantity/quality and rejects logistics

Guaranteed waste is only 80 TPD ±20% with up to 20% impurities allowed; Concessionaire still carries processing, KPI and rejects-haul risks to a disposal point up to 30 km.

Throughput guarantee references Design Capacity 80 TPD ±20%.
Availability KPI Guaranteed Availability 90%.

Construction / COD / Financial Close liquidated damages and default

COD delay LD = 0.1% of Performance Security per day; failure to achieve COD within 180 days of Scheduled Completion is Concessionaire Default; Financial Close delay LD = 0.05% of PS per day after 150 days.

Scheduled Completion is only 12 months / 365 days from Appointed Date — tight for Bio-CNG permitting + construction.
Failure to achieve Financial Close can terminate agreement and allow encashment of Bid Security / equivalent from PS.
Milestone defaults of 60 days can also drive termination pathway.

O&M KPI liquidated damages and hair-trigger default

Availability LD 0.02% of PS/day after 3-day cure; other KPI LD 0.05% of PS/day with 1st/2nd/3rd breach multipliers; aggregate monthly LDs >5% of PS = Concessionaire Default.

Third Breach uncured 10 days, or more than three Third Breaches in 12 months, is Concessionaire Default.
Performance Security must be replenished within 15 days after appropriation or face termination.

One-sided tax, site and change-in-law style cost risks

All taxes (including future prospective tax/levy changes) are Concessionaire’s; Authority disclaims site/data accuracy; water utility failure is Concessionaire’s problem at its cost.

Clause 5.19: future change in Taxes/Levies by Centre/State — no claim on Authority.
Performance Security Rs.1.5 Cr for full 21-year concession with mandatory renewals.

Equity lock-in, tech-provider lock-in and bid-process rigidity

Strict SPV shareholding lock-ins, technology provider retention for 5 years post-COD, no bid withdrawal after submission, and Bid Security forfeiture for LOA/CA/PS defaults.

SPV must be formed and CA signed within 30 days of LOA — compressed post-award timeline alongside Financial Close clock.

Contacts

The inviting authority and relevant contacts: office, person, designation, address, phone and email — and which address receives physical submissions, if any.

Inviting / contracting authority — Vellore City Municipal Corporation
