How banks appraise long-gestation, capex-heavy loans â from techno-economic viability and means-of-finance, to DSCR/IRR benchmarks, security structuring and the risks that most often sink a project loan.
Project Finance is long-term lending for a specific capital asset â a factory, power plant, road, or infrastructure asset â where repayment depends primarily on the future cash flows the project itself will generate, rather than the promoter's existing balance sheet. It typically involves a large one-time capex outlay, a long construction/gestation period before revenue begins, and repayment stretched over 7-20 years.
This is fundamentally different from working capital or a short-tenure term loan: the asset being financed doesn't yet exist or isn't yet earning, so the bank is effectively underwriting the promoter's projections of a future business rather than an operating track record.
Is the technology proven, is plant capacity realistic, are the technical/engineering consultants credible, and is the project cost per unit of capacity in line with comparable projects?
Is there genuine, durable demand for the output? Are the demand-supply projections independently verifiable, and is the pricing assumption realistic against current and likely future competition?
Do the projected cash flows support debt servicing with an adequate margin (DSCR), and is the Means of Finance (debt:equity mix) appropriate for the risk profile of the project?
Does the promoter group have the experience and financial strength to execute a project of this scale, and are all statutory clearances (environmental, land, regulatory) in place or clearly on track?

Progress reports, LIE certification, escrow & TRA monitoring
For projects above a bank's internal threshold, a Lenders' Independent Engineer (LIE) and, for consortium/multiple-banking cases, a Trust and Retention Account (TRA) mechanism are commonly mandated to monitor physical progress and cash-flow waterfall respectively.
| Metric | What It Shows | Typical Comfort Level |
|---|---|---|
| Average DSCR | Cash accruals available to service debt over the full repayment tenure | âĨ 1.5â2.0x for infra/core sector; âĨ 1.25x floor in any single year |
| IRR (Project) | Return the project generates on total capital employed | Comfortably above the weighted cost of capital |
| Debt-Equity Ratio | Promoter's skin in the game vs. bank funding | Commonly 2:1 to 3:1 depending on sector risk |
| Break-even Capacity Utilisation | Minimum utilisation at which the project turns cash-positive | Lower is safer â comfortably below the projected utilisation |
| Sensitivity/Stress DSCR | DSCR under a 10-15% cost overrun or delayed-completion scenario | Should stay above 1.0x even in the stressed case |
Cost or time overrun before the project starts earning. Mitigated by fixed-price EPC contracts, contingency provisioning and promoter/sponsor completion guarantees.
Output demand or price falls short of projections. Mitigated by long-term off-take/PPA agreements where available, and conservative demand assumptions.
Delay or change in statutory clearances, tariff policy, or environmental norms. Mitigated by verifying clearance status before financial closure and building buffer time into the schedule.
Raw material or fuel cost volatility eroding margins. Mitigated by long-term supply contracts or pass-through clauses where the sector allows.
Equity or subordinate debt not coming in on schedule, stalling the project mid-way. Mitigated by requiring proof of promoter contribution upfront, ahead of debt drawdown.
Inexperienced or overstretched promoter group. Mitigated by track-record checks, group exposure caps, and requiring a professional project management team.
