Project Finance — The Bankability Framework
Limited-recourse financing for industrial assets, explained the way lenders actually assess it.
What is project finance?
Project finance is the technique used to fund large, long-lived industrial assets — power plants, LNG trains, mines, ports, processing facilities, cold-chain complexes, renewable projects and heavy manufacturing — where lenders look primarily to the project's own cash flows and assets, not to sponsor balance sheets, for repayment. That limited-recourse quality is why project finance can support 60–80% leverage on tenors of 10–20+ years, while corporate lending against the same sponsor would rarely stretch that far.
Anatomy of a project-finance deal
A project-finance transaction is a network of contracts around a single Special Purpose Vehicle. Sponsors inject equity; lenders extend senior (and sometimes mezzanine) debt; the SPV enters into an EPC contract with an engineering firm, an O&M contract, one or more offtake or PPA contracts, feedstock or supply agreements, an insurance package, and holds the land, permits and IP required to operate.
Lenders take security over the SPV's shares, its bank accounts, its receivables, and its material contracts (via direct agreements with each counterparty). If the project underperforms, lenders can step in, replace the sponsor or operator, and preserve the cash flows that repay the debt.
Sizing the debt: DSCR and CFADS
The single most important number in a project-finance model is the Debt Service Coverage Ratio (DSCR): Cash Flow Available for Debt Service (CFADS) divided by scheduled debt service in the same period. Lenders size the loan so that the base-case DSCR sits comfortably above a covenanted minimum in every period across the tenor, and stress-test that the minimum holds under downside scenarios (price, volume, cost, FX, delay).
| Sector archetype | Typical minimum DSCR (base case) | Typical tenor | Debt:equity |
|---|---|---|---|
| Contracted renewables (long PPA) | 1.20x – 1.30x | 15–20 years | 70:30 – 80:20 |
| Regulated infrastructure | 1.25x – 1.35x | 15–25 years | 70:30 – 80:20 |
| Merchant industrial (long-term offtake) | 1.35x – 1.50x | 10–15 years | 60:40 – 70:30 |
| Fully merchant / commodity exposure | 1.60x – 2.00x+ | 7–12 years | 50:50 – 60:40 |

The bankability package
Bankability is about risk allocation. Every material risk in a project must be allocated to the party best able to manage it — and priced accordingly. A defensible bankability package typically includes:
- EPC contract with a lump-sum, date-certain, performance-guaranteed scope, liquidated damages and retention.
- O&M contract or operator agreement with clear KPIs and performance regime.
- Offtake or PPA that provides revenue visibility across the debt tenor.
- Supply / feedstock agreements that lock input economics.
- Insurance covering construction, operational, business interruption and environmental risks.
- Permits & land tenure with clean title and stakeholder consent.
- E&S compliance aligned with the Equator Principles / IFC Performance Standards.
From feasibility to financial close
Technical, market, environmental and financial feasibility. Preliminary financing plan, target capital structure, sensitivity model, indicative DSCR profile.
Ring-fenced SPV in the appropriate jurisdiction. Shareholders' agreement, sponsor support undertakings, equity funding plan (paid-in or committed via letter of credit).
EPC contract with liquidated damages and performance guarantees, O&M contract, feedstock/supply agreements, offtake or PPA, insurance package, land and permits.
Mandate to MLAs. Independent engineer, market consultant, insurance advisor, legal counsel, tax advisor and model auditor all appointed. Parallel workstreams over 3–6 months.
Common terms agreement, facility agreements, security agreements, direct agreements with contract counterparties, inter-creditor deed, hedging documentation. Conditions precedent lifted to reach financial close.
Milestone-based drawdowns during construction, transition to operating phase, DSCR tests, cash sweeps, reserve accounts and covenant compliance through the tenor.
When project finance is the right tool
- •Large capital projects with long useful life and stable cash flows
- •Projects with contractable revenue (offtake, PPA, tariff) or predictable market
- •Sponsors seeking off-balance-sheet treatment and ring-fenced risk
- •Cross-border deals where ECAs, DFIs and commercial banks can be syndicated
- •Short-cycle, opex-heavy, or trading businesses — corporate finance fits better
- •Projects where sponsors cannot fund the required equity or shareholder support
- •Assets whose economics depend on aggressive commodity or FX assumptions
- •Cost overrun and delay risk — margins in EPC and contingency budgets matter
- •Change in law and permitting risk in emerging jurisdictions
- •Currency mismatch between revenues (local) and debt (hard-currency)

Frequently asked questions
What is project finance?+
Project finance is a limited-recourse (or non-recourse) financing structure in which lenders look primarily to the cash flows and assets of a single project — held in a Special Purpose Vehicle (SPV) — for repayment, rather than to the balance sheet of the sponsors.
How is project finance different from corporate finance?+
Corporate finance is repaid from the borrower's whole business and secured against its full balance sheet. Project finance ring-fences one asset in an SPV; lenders' recourse is limited to that project's cash flows, contracts and security package. Sponsors' broader assets are (mostly) protected.
What is DSCR and why does it matter?+
DSCR — Debt Service Coverage Ratio — is Cash Flow Available for Debt Service (CFADS) divided by scheduled debt service in the same period. Lenders size debt to keep DSCR above a covenanted minimum in every period across the tenor. Typical minima: 1.20x–1.40x for infrastructure, 1.30x–1.50x+ for merchant industrial.
How much equity do sponsors typically need to contribute?+
For most industrial project-finance deals, sponsors provide 20–40% of total project cost as equity or subordinated shareholder loans, with senior debt covering the remainder. Debt:equity varies by sector, jurisdiction, offtake certainty and lender appetite.
What is a bankable project?+
A bankable project is one whose contractual, financial, technical and legal package supports lending on limited-recourse terms — i.e. lenders can be confident that CFADS will service debt through downside scenarios. Bankability is about risk allocation, not just a good business plan.
