Imagine a company wants to build a ₹2,000 crore toll expressway. It doesn’t have ₹2,000 crore sitting in the bank, and taking on that much debt directly on its own books could sink its balance sheet if the project runs into trouble. So how does it get built?

The answer, in most such cases, is project financing — a method of funding long-term, capital-intensive projects where the loan is repaid primarily from the cash flows the project itself generates, rather than from the promoter company’s overall balance sheet.

What Makes Project Financing Different

Traditional corporate loans are backed by the borrowing company’s entire asset base, credit history, and earnings. If the company defaults, lenders can go after its other businesses and assets too. Project financing works differently — it isolates the project into its own legal and financial silo.

The Special Purpose Vehicle (SPV)

Almost every project-financed venture is routed through a Special Purpose Vehicle — a separate legal entity created solely to build, own, and operate that one project. The SPV holds the project’s assets, contracts, and permits, and it is the SPV — not the parent company — that borrows the money.

Non-Recourse or Limited-Recourse Debt

Because the loan sits with the SPV, lenders typically have limited or no recourse to the sponsor’s other assets if the project fails. This is what makes project financing attractive to promoters — the risk is largely ring-fenced within the project — and it’s exactly why lenders scrutinise every assumption before signing off.

Key Features at a Glance

Feature	Description
Borrowing entity	A dedicated Special Purpose Vehicle (SPV), not the parent company
Primary security	Project’s future cash flows, contracts and assets
Recourse to sponsor	Limited or none, once completion risk is passed
Debt-to-equity ratio	Typically high — often 70:30 or 80:20 in infrastructure
Tenure	Long-term, often matched to the project’s operating life (10–25 years)
Lenders	Consortium of banks, NBFCs, DFIs, insurance and pension funds

The Four Stages of a Project-Financed Deal

Where the Money Comes From

A typical project financing structure blends several layers of capital:

• Senior debt — Term loans from banks, NBFCs, and infrastructure finance companies, usually the largest slice of funding.
• Subordinate or mezzanine debt — Higher-risk, higher-cost debt that sits behind senior lenders in the repayment order.
• Sponsor equity — Capital contributed by the promoter company, aligning their interests with the project’s success.
• Multilateral and DFI support — Institutions such as IREDA, IIFCL, and multilateral agencies often co-finance infrastructure and renewable energy projects in India.
• Bonds and structured instruments — Larger, operational projects sometimes refinance bank debt through infrastructure bonds once construction risk has passed.

Why Lenders Take It So Seriously

Because repayment depends entirely on the project performing as modelled, lenders don’t just check the promoter’s credit rating — they stress-test the project itself. This typically involves:

• Detailed cash flow modelling under multiple demand and cost scenarios
• Independent technical and legal due diligence on contracts, land, and clearances
• Risk allocation through contracts — construction risk to the EPC contractor, offtake risk through power purchase or toll agreements, currency risk through hedging
• Covenants such as minimum debt service coverage ratios (DSCR) that the SPV must maintain throughout the loan tenure

Common Use Cases in India

Project financing is the backbone of India’s infrastructure build-out. It’s the standard funding route for:

• Highways and expressways under BOT and HAM models
• Solar and wind power parks
• Airports, ports, and metro rail systems
• Large manufacturing plants, refineries, and petrochemical complexes
• Real estate townships and commercial developments

The Risks Worth Knowing

Project financing spreads risk cleverly, but it doesn’t eliminate it. Construction delays, cost overruns, regulatory changes, weaker-than-expected demand, and currency fluctuations can all strain a project’s ability to service its debt. This is precisely why every major risk in a project financing structure is contractually assigned to the party best placed to manage it — the construction company bears build risk, the offtaker bears demand risk, and the lender bears the residual financial risk.

The Bigger Picture

Project financing is what allows large, long-gestation assets to get built without overloading a single company’s balance sheet. It spreads risk across specialists, aligns everyone’s incentives to the project’s success, and lets capital flow toward the infrastructure a growing economy needs — one carefully structured deal at a time.
