Project finance: how to assess whether a project is bankable
A practical assessment of contracts, risks, DSCR, security and conditions precedent to understand project financing readiness.
Bankability means the ability to attract the required debt and equity under a risk allocation acceptable to the parties. A positive NPV alone does not establish it. This guide structures a readiness assessment: which cash flows support debt, who absorbs adverse outcomes and which evidence remains outstanding. GOUCAP provides analytical and structuring advisory services; it is not a lender and does not assure successful capital raising.
Decision summary
- Economic viability asks whether a project creates value; bankability asks whether an acceptable financing structure can actually be executed.
- Debt must fit available cash flow, contractual commitments and downside performance, rather than a preferred leverage target.
- Readiness develops through verified evidence, diligence and conditions precedent; a presentation or term sheet is not financial close.
1. Economic viability is not bankability
A project can have positive NPV and still run short of liquidity during early operations. Value creation over the asset's life does not establish sufficient cash at every payment date. Separate the unlevered project assessment, shareholder returns and the borrowing entity's repayment capacity. Each view supports a different decision and requires consistent assumptions.
The World Bank emphasises repayment capacity and contractual risk allocation. A practical assessment identifies which risk prevents a proposed financing structure, who could absorb it and at what cost. Lower debt may improve coverage while requiring more equity and changing shareholder returns. The structure needs to work for both creditors and sponsors, rather than optimising one metric independently of the other parties' requirements.
2. Project company and cash-flow ring-fencing
Define the project company, often a special-purpose vehicle, its shareholders, rights, obligations and accounts. Reconcile the legal perimeter with the model: who owns the asset, receives revenue, commissions construction and pays operating expenses? Cash from other group companies should not be treated as available without a documented transfer obligation and assessment of its effectiveness.
Ring-fencing involves more than incorporating a company. Examine related-party transactions, dividend distributions, intragroup contracts and restrictions on account movements. Recourse to sponsors depends on the negotiated documents. Project finance does not necessarily mean an absence of corporate support or automatic protection against every insolvency risk. Identify cash flows exposed to other obligations and obtain appropriate legal advice.
3. Construction, completion and operating risks
Translate the schedule into verifiable commitments covering engineering, procurement, works, testing and operations. Identify contractor interfaces, cost contingency, currency exposure and responsibility for delays. A fixed contract price does not eliminate scope exclusions, contractor failure or caps on compensation. The risk matrix should show what remains with the project after contractual protections, rather than treating every allocated risk as fully resolved by a contract label.
Physical completion and completion under the financing agreement may use different criteria. Record performance tests, operating permits and conditions for releasing sponsor support. Then model maintenance, availability, productivity and replacements. Insurance may cover defined events but does not replace commercial performance. For each mitigation, identify its owner, supporting evidence, response time and residual exposure.
4. Revenue, supply and concession contracts
The model should reproduce contractual economics, not just headline terms. Examine volume, price, indexation, currency, tenor, quality, penalties and suspension or termination provisions. Distinguish contracted revenue from commercial intentions and market exposure. Even a purchase obligation depends on counterparty credit quality and the conditions required for enforcement. Check delivery, acceptance and performance requirements before recognising revenue.
Compare revenue, supply and debt maturities. A long concession does not resolve a critical input secured only for a short period. Test indexation mismatches, shared infrastructure availability and renewal of essential agreements. Concessions may also impose investment and asset-handback obligations. Legal opinions and commercial diligence should challenge material interpretations embedded in cash flow, especially where compensation, tariff adjustment or extension depends on a future approval.
5. Security, sponsor support and step-in rights
Distinguish security over assets and rights, third-party guarantees and sponsor equity commitments. Identify the beneficiary, amount, duration, enforcement trigger and financial capacity of the supporting party. A limited cost-overrun undertaking does not automatically cover all debt. Legal assessment should address creation, priority, enforceability and jurisdiction-specific restrictions. Test whether support remains credible under project stress.
Step-in rights can enable intervention or management replacement in agreed circumstances to preserve continuity. Their effectiveness depends on direct agreements, consents and procedures, not simply the words appearing in a contract. Record cure periods and interfaces with the granting authority and suppliers. Security redistributes potential losses; it does not make weak operating cash flow economically sustainable or remove the need to assess the underlying business.
6. Debt sizing and DSCR
DSCR divides cash flow available for debt service, often called CFADS, by debt service for the same period. Contractual definitions govern both amounts: check taxes, working capital, maintenance, interest and principal treatment. EBITDA is not an automatic substitute for available cash. Calculate coverage by payment period, preserving seasonality and matching collection and payment dates.
As a purely arithmetic illustration, CFADS of 130 and debt service of 100 produce DSCR of 1.30x; this is not a universal approval threshold. Acceptable coverage depends on risk, contracts and lender criteria. Size tenor, grace periods and amortisation alongside interest, reserves, currency exposure and concentrated maturities. Future refinancing should be presented as a risk, not an assured cash inflow that conveniently closes a funding gap.
7. Covenants, reserve accounts and security package
Covenants are contractual obligations that may include financial limits, dividend restrictions, additional borrowing controls and reporting duties. Distinguish distribution lock-up, reserve replenishment requirements and events of default. Model triggers and cure periods according to the documents. A debt-service reserve account can cushion a temporary mismatch, but requires funding and clear replenishment rules. Show the effect on equity needs and distributable cash rather than treating reserves as costless protection.
The package should integrate accounts, payment priorities, security and intercreditor arrangements. Where applicable to the financing, Equator Principles EP4 also addresses environmental and social undertakings and independent monitoring. It is not a general project certification and does not replace permits. Assess applicability, specific obligations and the resources required for compliance during construction and operations.
8. Downside, sensitivities and break-even
A sensitivity isolates one variable; a downside combines compatible shocks. Test delay alongside higher cost, lower demand alongside slower ramp-up, and price or interest changes where relevant. Track minimum DSCR, cash deficits, reserve use and additional equity. Show when the structure breaks: a comfortable average ratio can conceal an unfunded payment date. Preserve operational consistency rather than stacking unrelated shocks simply to produce a dramatic result.
Calculate price, volume or availability break-even against debt service and covenant requirements. This threshold need not match the point at which NPV becomes zero. Explain which corrective actions are contractually possible and how long they take. Do not count the same contingency as unrestricted cash and construction protection. Assumed responses need owners and evidence; an uncommitted shareholder injection is a dependency, not an established mitigation.
9. Conditions precedent and diligence gaps
Bring technical, commercial, legal, tax, financial, environmental and social diligence into one register. For each gap, identify the impact, expected document, owner, deadline, acceptance test and authorised approver. Receiving an answer does not automatically close an issue. Separate conditions for signing, first drawdown and subsequent obligations according to transaction documents. Track versions to identify amendments that invalidate earlier diligence.
Land availability, permits, effective contracts, equity contributions and security creation may form part of this process, depending on the structure. Financial close requires the commitments and requirements defined for the transaction; an internal approval or draft agreement alone does not establish it. Confirm which conditions are satisfied, formally waived or outstanding, and distinguish signing from access to funds.
10. Financing-readiness checklist
The assessment should produce a readiness memorandum supported by a reconciled model, risk matrix and evidence register. Show the intended structure, capital alternatives, unagreed terms and residual risks. Identify dependencies between actions: signing debt before resolving an engineering interface may merely move uncertainty into a condition that is difficult to satisfy. Prioritise gaps that change debt capacity or prevent investment.
Conclude through evidence gates: consistent perimeter, reviewed contracts, allocated risks, downside-tested debt and conditions verified by the competent parties. The next step may be further diligence, resizing or pausing the investment decision. GOUCAP can support analytical preparation and structuring, but approvals, terms and capital availability depend on third parties. Financing readiness is a sequence of substantiated decisions, not a promise that funding will be obtained.

Frequently asked questions
- Is positive NPV enough to obtain financing?
- No. Positive NPV indicates value creation under selected assumptions, not repayment capacity on every due date. Contracts, risks, liquidity, equity contributions and lender acceptance need separate assessment.
- Which DSCR makes a project bankable?
- There is no universal number. Available-cash definitions, testing frequency, risk profile and contractual criteria matter. Examine minimum coverage and downside deficits without turning an arithmetic example into a lending rule. Evaluate proposed thresholds within the complete transaction structure.
- Can guarantees replace cash flow?
- No. They may protect against particular losses or events, subject to legal effectiveness and guarantor capacity. Ordinary repayment still depends on the resources provided by the structure. Guarantees do not remove the need for sustainable operations or make every commercial risk acceptable.
- Do covenants matter only after drawdown?
- No. Model them during structuring because they affect distributions, reserves, equity requirements and operating flexibility. Documents define tests, consequences and cure periods; these must align with the model and be monitored throughout the financing. Address projected breaches before making commitments.
- Does a term sheet mean financial close?
- No. A proposal or term sheet may be conditional and may not constitute a definitive commitment. Verify executed agreements, approvals and closing requirements, then check drawdown conditions separately. Advisory work and documentation preparation do not assure approval, acceptable terms or availability of funds.
