Project finance vs corporate finance
Two ways to pay for a big asset
Imagine a company wants to build a 200 MW solar plant. It can pay in two broad ways.
Corporate finance (on-balance-sheet): the company borrows or uses its own funds, and lenders look to the whole company's balance sheet and cash flows for repayment. If the solar plant fails, lenders can still claim against the company's other businesses.
Project finance (off-balance-sheet or limited recourse): a new, legally separate company, the special purpose vehicle (SPV), is created to own the project. Lenders are repaid only from the project's own cash flows, and their security is the project's assets, contracts and shares. The sponsors' exposure is largely limited to the equity they invest (plus any specific support they agree to provide).
| Feature | Corporate finance | Project finance | |---|---|---| | Borrower | Existing company | Newly formed SPV | | Repayment source | All company cash flows | Project cash flows only | | Recourse to sponsors | Full | None or limited | | Typical leverage | Lower, set by company credit | Often high, set by project cash flow strength | | Due diligence | Company-level | Very detailed project-level (technical, legal, market, insurance, model) | | Documentation | Relatively simple | Complex contract web | | Transaction cost and time | Lower, faster | Higher, slower |
Why use project finance?
- Risk ring-fencing: a failure does not sink the sponsor.
- Higher leverage: strong contracted cash flows can support more debt, improving equity returns.
- Risk sharing: risks are allocated by contract to the parties best able to manage them.
- Enabling large projects: sponsors can undertake projects larger than their balance sheets would allow.
- Discipline: lenders' scrutiny often improves project structuring.
Project finance is widely used for power generation (including renewables), transmission, water and desalination, toll roads, airports, social infrastructure under PPPs, telecoms infrastructure, and resources. In the Gulf, independent power and water projects (IPPs/IWPs) have long relied on it; Pakistan has used it for IPPs and infrastructure; the UK pioneered PFI and later PPP models; the US uses it widely for energy projects and increasingly for infrastructure.
The SPV and the contract web
The SPV sits at the centre of a network of contracts:
Sponsors (equity) ──── Shareholders' agreement
│
Lenders ── Loan agreement ─┤
(security, accounts) │
┌─── SPV ───┐
Offtaker/grantor ─┤ ├─ EPC contractor (build)
(PPA / concession) │ ├─ O&M operator (run)
Fuel/input supplier ├─ Insurers
└─ Government permits/licences
Each contract allocates specific risks. For example, the EPC contract typically transfers construction cost and time risk to the contractor through a fixed price, a completion date and liquidated damages. The offtake agreement (e.g., a power purchase agreement) provides revenue certainty.
Limited vs non-recourse
Pure non-recourse finance is rare. Sponsors often provide limited support such as completion guarantees during construction, equity commitment letters, or cost-overrun facilities. Once the project reaches stable operations, recourse typically falls away. Understanding exactly what support is given, and when it ends, is critical for sponsors.
Worked example: choosing the route
Illustrative. Falcon Utilities, a fictional mid-sized UAE company, has equity of $300M and wants to develop a $450M desalination plant with a 25-year water purchase agreement from a creditworthy state utility.
- Corporate route: borrowing $350M on its balance sheet would stretch its credit metrics and risk a downgrade, and a problem at the plant would affect the whole company.
- Project finance route: an SPV raises roughly 75–80% debt against the contracted cash flows (illustrative gearing), with Falcon and a partner contributing the equity. Falcon's exposure is limited to its share of equity plus a completion support package that ends at commercial operation.
Falcon chooses project finance, accepting higher transaction costs and a longer timeline in exchange for risk ring-fencing and scalable leverage.
When project finance is a poor fit
- Small projects where transaction costs outweigh benefits.
- Projects without predictable, contractable revenues (unless sponsors accept merchant risk and lenders price it).
- Situations requiring speed and flexibility that complex documentation would slow down.
- Weak legal frameworks where contracts and security are hard to enforce.
Common mistakes
- Assuming "non-recourse" means sponsors carry no risk at all.
- Underestimating the time and cost of due diligence and documentation.
- Treating the SPV as a formality rather than the legal and financial core of the deal.
- Ignoring how contracts interact; a gap between the EPC and offtake terms can leave the SPV exposed.
Hands-on: a route-selection scorecard in Excel
Columns: A Criterion | B Weight | C Score (1–5) | D Evidence
A2 Predictable, contractable revenue B2 30%
A3 Project size relative to sponsor B3 20%
A4 Need to ring-fence risk B4 20%
A5 Legal framework for contracts/security B5 15%
A6 Tolerance of time and transaction cost B6 15%
C8 Weighted score =SUMPRODUCT(B2:B6, C2:C6)
C9 Indication =IFS(C8>=4, "Project finance: strong fit", C8>=3, "Consider; test with lenders", TRUE, "Corporate finance likely better")
C10 Weight check =IF(ROUND(SUM(B2:B6),4)=1, "OK", "Weights must total 100%")
Weights and thresholds are illustrative; the scorecard structures a discussion with advisers, it does not replace one.
Template: contract map for an SPV
| Contract | Counterparty | Main risk allocated | Key terms lenders check | Gap to watch | |---|---|---|---|---| | Offtake (PPA/WPA) | State utility | Revenue, price | Tenor ≥ debt + tail; termination payments | Late-COD penalties vs EPC damages | | EPC | Contractor | Construction cost and time | Fixed price, LDs, caps, bonds | LD cap too low | | O&M | Operator | Operating performance | Availability guarantees, penalties | Alignment with EPC warranties | | Supply | Supplier | Input availability and price | Pass-through, volumes | Mismatch with offtake indexation | | Loan and security | Lenders | Funding | Covenants, accounts, security | Cross-default triggers | | Shareholders' agreement | Sponsors | Governance, equity funding | Funding commitments, exits | Deadlock provisions |
Second worked example: a renewable IPP in Pakistan
Illustrative. A developer plans a 50 MW solar IPP with a 25-year energy purchase agreement. Contract mapping shows the tariff is partly indexed to USD while 30% of debt would be in local currency: a partial natural hedge. It also shows the grid connection is the utility's responsibility, so the team negotiates deemed-energy payments if the grid is not ready. Both findings are resolved before lenders' due diligence starts, shortening the path to close.
How to measure success
- Every risk in the contract map has a named counterparty and mechanism.
- No unresolved gaps between offtake penalties and EPC damages before lender engagement.
- Sponsor support obligations are listed with their end dates.

Two ways to pay for a big asset
Imagine you run a successful mid-sized utility, and you've been offered the chance to build a four hundred and fifty million dollar desalination plant, with a twenty-five-year contract to sell the water. It's a great opportunity. It's also bigger than your whole company's equity. If you borrow against your balance sheet and the plant runs into trouble, it could take the rest of the business down with it. So how do organisations build assets larger than themselves, without betting the company? That's what project finance is for. In this lecture you'll learn the difference between corporate and project finance, how a special purpose vehicle sits at the centre of a web of contracts, what limited recourse really means, and when project finance is the wrong tool. By the end, you'll be able to explain which route suits a given project, and why.
Why it matters
Why does this matter? Because the choice of financing route shapes everything that follows: the risk the sponsor carries, how much debt the project can raise, how long it takes to reach financial close and how much it costs in advisers and documentation. Project finance ring-fences risk: if the project fails, lenders generally can't pursue the sponsor's other businesses. It can support higher leverage, because lenders size debt on strong, contracted cash flows. It allocates risks to the parties best able to manage them, through contracts. And lender scrutiny often improves the project's structure. That's why it's used so widely for power and water in the Gulf, independent power projects in Pakistan, public-private partnerships in the UK, and energy and infrastructure in the US.
The concept: a ship in its own harbour
Here's the key idea. In corporate finance, the company borrows, and lenders look to the whole company's balance sheet and cash flows for repayment. In project finance, a new, legally separate company is created just to own the project. That's the special purpose vehicle, or SPV. Lenders are repaid only from the project's own cash flows, and their security is the project's assets, contracts and shares. The sponsor's exposure is largely limited to the equity it invests, plus any specific support it agrees to. Think of it like building a ship in its own harbour, with its own crew, its own cargo contracts and its own insurance. If the ship sinks, the harbour master can't come after your other ships. But because of that, the people lending for the ship want to inspect every plank, every contract and every captain before they lend a penny.
The contract web
The SPV sits at the centre of a web of contracts, and each contract allocates specific risks. The offtake agreement, such as a power or water purchase agreement, provides revenue certainty from a creditworthy buyer. The EPC contract, engineering, procurement and construction, typically transfers construction cost and time risk to the contractor through a fixed price, a completion date and liquidated damages. The operations and maintenance contract passes performance risk to an experienced operator. Supply agreements cover fuel or inputs. Insurances cover physical damage and business interruption. Permits and licences come from government. Lenders sign the loan and security documents, plus direct agreements that let them step in and cure a default before a key contract is terminated. And sponsors sign the shareholders' agreement. Here's the thing to remember: bankability lives in the gaps between these contracts.
Worked example one: a small comparison
Let's start with a simple case. A company with fifty million of equity wants to build a twenty million pound warehouse extension for its own use. There's no separate revenue contract; the warehouse just makes the existing business more efficient. Should it use project finance? Almost certainly not. There's no independent cash flow for lenders to rely on, and the legal, technical and model due diligence could cost a large share of the project value and take many months. Corporate finance is faster, simpler and cheaper here, and the risk is well within the company's capacity. Notice the reasoning: project finance isn't 'better'. It fits projects with large capital costs, predictable contractable revenues and a need to ring-fence risk.
Worked example two: Falcon Utilities
Now the realistic example from the lesson. Falcon Utilities, a fictional mid-sized UAE company, has three hundred million dollars of equity and wants to develop a four hundred and fifty million dollar desalination plant, with a twenty-five-year water purchase agreement from a creditworthy state utility. The corporate route means borrowing around three hundred and fifty million on its own balance sheet. That would stretch its credit metrics, risk a downgrade, and expose the whole company to one plant. The project finance route: an SPV raises roughly seventy-five to eighty per cent debt against the contracted cash flows, which is illustrative gearing, with Falcon and a partner providing the equity. Falcon's exposure is its share of equity plus a completion support package that ends at commercial operation. Falcon chooses project finance, accepting higher transaction costs and a longer timeline in exchange for ring-fencing and scalable leverage.
Watch me do it: a route-selection scorecard
Let me show you a simple scorecard I use to structure the conversation. Five criteria. First, how predictable and contractable is revenue? Second, how large is the project relative to the sponsor's balance sheet? Third, how important is ring-fencing the risk? Fourth, how strong is the legal framework for contracts and security? And fifth, how tolerant are we of the extra time and cost? I give each a weight and a score from one to five, and a SUMPRODUCT gives a total. For Falcon: revenue five, a twenty-five-year contract with a strong buyer. Size five. Ring-fencing four. Legal framework four. Time and cost tolerance two, because they'd like to move quickly. The total points clearly to project finance. It doesn't make the decision for you. It makes the reasoning visible and comparable.
Limited recourse, and when it fits poorly
Now a subtle point. Pure non-recourse finance is rare. Sponsors often provide limited support, such as completion guarantees during construction, equity commitment letters or cost-overrun facilities. Once the project reaches stable operations, that recourse usually falls away. Understanding exactly what support you've given, and when it ends, is critical for sponsors. And project finance is a poor fit for small projects where transaction costs outweigh the benefits, for projects without predictable, contractable revenue, unless sponsors accept merchant risk and lenders price it, for situations needing speed and flexibility, and in jurisdictions where contracts and security are hard to enforce.
Common mistakes
Let's cover the common mistakes. First, assuming non-recourse means the sponsor carries no risk at all. Completion support, equity commitments and reputation are all real exposures. Second, underestimating the time and cost of due diligence and documentation. Third, treating the SPV as a formality rather than the legal and financial core of the deal. And fourth, ignoring how contracts interact. For example, if the offtake agreement penalises the SPV for late commercial operation, but the EPC contractor's delay damages are capped at a lower amount, the SPV is left holding the difference. That gap is exactly what lenders' advisers will find, so find it first.
Recap and try this now
Let's recap. Corporate finance uses the whole company's balance sheet, with full recourse. Project finance creates an SPV whose lenders are repaid from the project's own cash flows, secured on its assets, contracts and shares, with limited recourse to sponsors. The SPV sits at the centre of a contract web, where each contract allocates a specific risk, and bankability depends on those contracts fitting together without gaps. Project finance suits large, contractable, long-lived assets; it's a poor fit for small, uncontracted or urgent ones. Your try-this-now: pick a real type of infrastructure in your country, perhaps a solar plant, a toll road or a hospital. List the contracts the SPV would need, and the main risk each contract allocates.
Key takeaways
- Project finance lends to an SPV and relies on project cash flows, with limited or no recourse to sponsors.
- Benefits include risk ring-fencing, higher leverage and contractual risk sharing; costs include complexity and time.
- The SPV sits at the centre of a contract web (loan, EPC, O&M, offtake, supply, insurance, permits).
- Pure non-recourse is rare; sponsors often provide limited support such as completion guarantees.
