Public-Private Partnership (PPP) — definition
Long-term arrangement between a government entity and a private company to finance, build and often operate infrastructure or industrial facilities that serve a public purpose.
PPP structures typically allocate design, financing, construction and sometimes operational risk to the private partner in exchange for payments over an extended contract term, such as availability payments or user fees. They are commonly used for infrastructure with public benefit, including utilities, transport and certain industrial or agro-processing facilities.
Why it matters to industrial buyers
PPPs can mobilise private capital and expertise for projects that governments might otherwise struggle to fund or deliver alone, but they involve complex long-term risk-sharing arrangements.
Key reference points
Typical contract length
PPP contracts commonly run for 15-30 years, reflecting the long asset life and financing horizon involved.
Commonly confused with
Project finance
PPP describes the contractual partnership structure between public and private parties; project finance describes a funding technique that may be used to finance a PPP or a purely private project.
How it is used in practice
A regional government enters a public-private partnership to develop and operate a shared industrial processing facility.
