How does BIG LOANS work with infrastructure developers?

BIG LOANS arranges ₹100 crore-and-above project finance for Indian infrastructure — roads (NHAI HAM, BOT, TOT concessions), ports, airports, urban transport (metros, MMRDA, similar), and city infrastructure. Infrastructure project finance has the longest tenors in Indian debt — typically 18-22 years for road HAM, 15-20 for ports, matched to concession period. The lender universe is dominated by infrastructure NBFCs (IIFCL, REC, PFC), multilateral co-financiers (ADB, World Bank, AIIB), and selectively private banks for top-developer projects.

Section 01 — Infrastructure debt landscape

Longest tenors, regulated cash flows.

Infrastructure project finance has the longest tenor and most predictable cash flows of any Indian debt product. HAM (Hybrid Annuity Model) road concessions are particularly clean — 40% annuity from NHAI on COD, 60% from toll/balance annuity over 15-year operational period. Lenders price these tightly because counterparty (NHAI) is sovereign-equivalent.

Ports and airports follow similar long-tenor concession structures, with revenue mixes between regulated tariffs, traffic / cargo throughput, and ancillary income. IIFCL anchors most large infra project finance; multilateral co-financing with ADB, World Bank, AIIB layers on top with concessional pricing.

Section 02 — Common funding situations

When infrastructure businesses approach us.

Common funding situations across Indian infrastructure.

01

Road HAM project

Hybrid Annuity Model road concession. NHAI pays 40% during construction (5 tranches), 60% as annuity post-COD. Project finance ₹500-3,000 Cr.

02

Road BOT / TOT

Build-Operate-Transfer or Toll-Operate-Transfer. Revenue is toll-based; lender comfort needs traffic study. Higher risk than HAM.

03

Port project finance

Port construction, expansion, or capacity addition. Concession-based revenue mix with cargo throughput risk. ₹500-5,000 Cr.

04

Airport project finance

Greenfield airport or major terminal expansion. Long-tenor concession. ₹1,000-10,000 Cr.

05

Urban infrastructure

Metro lines, urban water, sewage, smart city infrastructure. Often involves state government counterparty plus multilateral co-financing.

06

Operational asset refinancing

Operational infra asset 2-3 years post-COD refinanced into longer-tenor cheaper debt. Major IRR booster for sponsor.

Section 03 — Best-fit products

Products that fit infrastructure.

Infrastructure is dominated by project finance, with refinancing into NCDs / bonds at operational stage.

Section 04 — Lender appetite

IIFCL-anchored, multilateral-layered.

Infrastructure lending has a small specialist universe led by IIFCL, infrastructure NBFCs, and multilateral co-financiers.

01

IIFCL (anchor)

India Infrastructure Finance Company — anchor lender for most large infrastructure project finance. Sovereign-backed, longest tenors.

02

Infrastructure NBFCs

REC, PFC (primarily power), Power Finance Corp, plus dedicated infrastructure NBFCs.

03

Multilateral co-financiers

ADB, World Bank (IBRD/IDA), AIIB, JICA — concessional pricing, longer tenors, often layered with IIFCL or PSU bank debt.

04

PSU banks (syndicate)

SBI, BOB, Union Bank — participate in syndicates for large infra deals (₹1,000 Cr+).

05

Private banks (selective)

HDFC, ICICI, Axis — selectively active for top-developer infra (L&T IDPL, GMR, IRB, Adani).

06

Infrastructure InvITs

Increasingly active as operational asset acquirers — refinancing pipeline for sponsor IRR realisation.

Section 06 — FAQ

Infrastructure debt — FAQs.

18-22 years matching the concession period. Construction period 2-3 years (interest-only / partial principal), then 15-17 years of operational repayment from NHAI annuity. Pricing tight because counterparty is sovereign-equivalent.
IIFCL (India Infrastructure Finance Company Limited) is the dedicated infrastructure lender of GoI. It anchors most large infrastructure project finance, often as the largest single lender in a syndicate. Sovereign-backed, can lend longer tenors than commercial banks.
Multilateral (ADB, World Bank, AIIB) lends alongside Indian banks/NBFCs at concessional rates. The multilateral typically takes a senior position with some specific protections; commercial lenders take the bulk of debt. Tenor extension and pricing benefits flow to the project.
Yes — and increasingly common. Operational HAM road, port, airport refinanced into 15-year NCD listed on BSE/NSE WDM market. Investors include insurance companies, pension funds, AIFs. Pricing 50-150 bps below original project debt.
