Project Financing Models

Infrastructure development runs on capital, and the way that capital is raised shapes almost everything about how a project is structured, who carries the risk, and how quickly it reaches financial close. There are three broad approaches to financing a capital project, and knowing which one fits — and why — is one of the first questions any sponsor needs to answer.

Corporate financing

Under corporate financing, the sponsor borrows against its own balance sheet. Lenders look at the company's existing cash flows and assets as security, and in the event of default, the lender can pursue those corporate assets directly. It's straightforward, but it ties the project's fate to the sponsor's broader financial health — and it isn't available to sponsors without a strong existing balance sheet.

Structured financing

Structured finance sits a level up in complexity. It ranges from relatively simple arrangements that lower a corporate borrower's funding costs, through to more elaborate structures built around special purpose entities and layered debt instruments. Project finance itself is best understood as a subset of structured finance.

Project financing

In a true project financing, a special purpose vehicle (SPV) is created specifically for the project, with no operating history of its own. Because there's no track record to lend against, the project's creditworthiness rests entirely on its anticipated cash flow, the value of its collateral, and the contractual support provided by sponsors, off-takers and other counterparties. Lenders need to be convinced the project has secure inputs, capable management, and is both technically feasible and economically viable.

The appeal of this model is that it allows major infrastructure — energy, transport, and other public-facing assets — to be built and refinanced with private capital, often at lower relative risk to the sponsor and lower cost of capital than a fully corporate-backed alternative. Three structures dominate infrastructure project financing in practice: Build-Operate-Transfer (BOT), Public-Private Partnership (PPP), and Asset-Backed Securitisation (ABS).

Why this matters at the outset

The financing route a sponsor chooses shapes the entire bankability conversation that follows — what documentation lenders will expect, how risk gets allocated across the contract stack, and how long the path to financial close will realistically take. Getting this decision right early, before a data room is assembled or a lender approached, is one of the highest-leverage moments in the life of a project.

Choosing the right structure is the starting point. Making the underlying project bankable within that structure — a sound financial model, clean risk allocation, a data room that stands up to scrutiny — is the work that actually gets a deal to close.
