In today’s article, we will talk about the role of the Government and public private partnerships in project finance.


A public-private partnership or PPP is a long-term contract between a private party and a government for providing a public service, in which the private party bears significant risk and management responsibility.


Such public private partnerships, apart from the contract, are also backed by legislation, which explicitly define the role of the parties and their obligations.

PPP as we know it today has evolved from a power purchase agreement model used to develop power generation plants in the United States in the 80s, following Private Utility Regulatory Policies Act in 1978.

Under the PPA, regulated utilities would commit for a long-term to purchase power, which enabled the finance to be raised for the power generation plant, using the PPAs as security.

A key aspect of a PPA is that the project company that builds and operates the power station does not take any risk on whether the electricity which it has the capacity to generate is actually needed: the demand and price risk remains with the utility, which pays the availability charge whether it uses any power or not.

So, the PPA model is essentially the same project finance transaction model we have developed so far in this course.

The financial players provide capital in the form of equity and debt.

The EPC contractor designs and builds the project.

The O&M contractor manages the project when the project is operational.

The supplier supplies the raw material.

Finally, the buyer commits to purchase the product under a long term PPA.

PPA model

Soon, the success with the PPA model encouraged public authorities around the world to use it to attract private investments into development of social and economic infrastructure sectors.

The attraction of the private capital into many infrastructure sectors such as hospitals, schools and prisons, where revenue risk could not be borne by the private sector, required development of public private partnership legislation. And, one dominant from of PPP has emerged which is a concession agreement between the government and the private party.

The concession agreement is essentially a license given by the government to the private party to carry out investments into a particular project. It defines the length of the operation of the project by the private party, requirements to operate the project, investment recovery method, ownership, and other issues. Roughly, 20% of project financing happens in the concessions projects.

Concession agreement has taken many forms such as Build Own Operate contract, which closely resembles the PPA model. Build Own Transfer contract, and Design Built Finance Operate contract just to name a few.

So, under the Build Own Operate contract the ownership of the project remains private. The financing of the construction costs also come from private sources. However, either government or general users pay the private party for the service provided.

Build own transfer contract resembles the BOO contract, except the ownership of the project remains private only during the term of the contract. Upon contract expiry or termination, the ownership transfers to the government.

And, finally, under the Design Built Finance Operate contract, the ownership remains public from the start of the concession. The private party finance the construction of the project, carries out operation of the project, and, government or general users pay the private party for the service provided to recover private party’s investment.

Concession agreement

We mentioned that one of the items that the concession agreement defines is the investment recovery method, and, typically, under the concession agreement the Government is granting the right to the project company to collect the revenues from individual users. The project company may have a project agreement, such as a power purchase agreement, with an off-taker, such as State Owned Grid Company, under the concession agreement, or, the project company may collect the tolls from the toll users in a toll project.

Sometimes, the project company collects the revenue and passes revenue through to the Government, and, instead, the project company receives a guaranteed payment, sometimes called availability payment from the Government. Under this scheme, the project company receives a secured stream of revenue from a Government, which is a low-risk counterparty.



It is usual for the project company to receive a minimum guaranteed revenue from the Government, whenever there is volume risk present in the revenue. For example, this might the case with the toll road projects, where private operator collects the tolls, and in case of insufficient revenue, the Government steps in and compensates the private operator. The whole idea is to transfer the risks associated with the project’s revenue to the Government.
