The aim of PPPs is to use private capital to finance and build major public infrastructure projects. The investors earn a return, while cash-strapped governments put less long-term debt on their books and complete projects that might otherwise have taken longer, or not happened at all. P3s, however, aren’t free money and come with taxpayer risks, experts say. Current law also limits PPPs to development of facilities related to early child care, education, health, housing and transportation. Projects must also generate revenue (and draw other funding) sufficient to cover their cost, maintenance and operation.
