Project finance is a method of funding large capital projects where the lender or investor looks primarily at the project's own cash flows as the basis for repayment — rather than the creditworthiness of the project's sponsors.
This distinction is fundamental. In a conventional bank loan, the lender assesses the borrower's balance sheet, assets, and credit history. In project finance, the lender assesses the project: its contracts, its revenue predictability, its risk profile, and its ability to generate enough cash to service debt and return equity.
How it works in practice
A typical project finance structure works like this:
- The developer establishes a Special Purpose Vehicle (SPV) — a new company that will own and operate the project
- The SPV enters into a set of contracts: an offtake agreement with the customer, a construction contract with the contractor, an operations agreement with the operator, and land agreements
- Lenders provide debt to the SPV — typically 60–80% of the total project cost
- Equity investors (including the developer) contribute the remaining 20–40%
- During operations, the SPV's revenues flow first to operating costs, then to debt service, then to equity returns
Who provides the financing?
Project finance in Africa typically involves a combination of:
- Development Finance Institutions (DFIs) — institutions like the IFC, AfDB, DEG, Proparco, DBSA, and others that specifically target infrastructure in developing markets. They often provide both debt and equity and are frequently the anchor investor that brings commercial lenders along.
- Commercial banks — both local and international banks that provide senior debt. They typically require DFI participation and will follow the DFI's due diligence standards.
- Equity investors — infrastructure funds, impact investors, and strategic investors who take equity stakes in return for long-term returns.
- Export credit agencies — government-backed agencies that provide financing linked to procurement from their home countries (relevant when equipment is being imported).
The debt service coverage ratio (DSCR)
The single most important financial metric in project finance is the Debt Service Coverage Ratio. It measures how many times the project's cash flow covers its debt repayments in any given period.
A DSCR of 1.0x means the project generates exactly enough cash to service its debt — no margin. Lenders typically require a minimum DSCR of 1.2x to 1.4x, with higher ratios preferred. If your project's financial model shows a DSCR below 1.2x in any period, lenders will not proceed.
Why project finance — not a regular business loan?
For large infrastructure projects, project finance is often the only viable option. A conventional business loan of $30 million would require the borrower to have significant existing assets and revenue. Most infrastructure developers — especially first-time developers — do not. Project finance allows the project itself to be the collateral, making large-scale development possible for developers who are asset-light at the outset.
