Document Summary:

The Private Participation in Infrastructure (PPI) Project Database has data on over 6,400 infrastructure projects in 137 low- and middle-income countries. The database is the leading source of PPI trends in the developing world, covering projects in the energy, transport, water and sewerage, ICT backbone, and Municipal Solid Waste (MSW) sectors (MSW data includes projects since 2008) Projects include management or lease contracts, concessions, greenfield projects, and divestitures.

The data is presented in a variety of ways useful to researchers, policy makers, journalists and others.

Methodology for PPP projects and investment:

The data for the number of PPP projects and investment is obtained by conducting custom queries in the Private Participation in Infrastructure (PPI) database - which draws its information exclusively from publicly available sources. The PPI database only includes information on low and middle income countries.

Types of projects covered:

  • The PPI Database defines as a PPI project one in which a private company or investor bears a share of the project's operating risk, i.e. a private sponsor is at least partially responsible for the operating cost and associated risks. This could be by either having the rights to operate alone or in association with a public entity or owning an equity share in the project. Accordingly, the database tracks management and lease contracts, greenfield projects, merchant, brownfield projects, and divestiture, among others. 
  • The PPP Knowledge Lab defines a PPP as “a long-term contract between a private party and a government entity, for providing a public asset or service, in which the private party bears significant risk and management responsibility, and remuneration is linked to performance.” This definition excludes divestitures, as well as merchant projects, in which a private sponsor builds a new facility in a liberalized market and for which the government provides no revenue or payment guarantees. As a result, PPP projects tracked in this site are only a subset of those monitored in the PPI database.      

Sectors covered:

  • The PPI database only tracks projects in energy, information and communication technology (ICT), transport, and water and sewerage sectors. Therefore, the number of PPP projects and investment in this page reflects this.

Featured projects:

  • Each country page lists the ten largest and ten most recent projects for active and total PPP projects. The full list is available in the PPI Database  and is accessible by creating a custom query following the PPP Knowledge Lab’s customization described above.

Definition of investment amounts

  • With few exceptions, the investment amounts in the PPI database (and therefore those reported on this page) represent the total investment commitments by the project entity at the beginning of the project (at contract signature or financial closure). This amount does not reflect the planned or executed annual investments. For projects that involve investments, the database figures reflect total project investments encompassing shares of both private and public parties.
