Screening for PPP Potential

At some point in the process of identifying priority public investments, or sector reform options, projects may be screened for their potential to be implemented as a PPP. The objective of this screening is to identify—based on the available information—whether the project may provide better value if implemented as a PPP.

In practice, different governments do this PPP screening at different stages, as described in PPP Selection in the Public Investment Planning Process. Some may screen all projects, as part of a comprehensive procurement options analysis, as described in (Burger and Hawkesworth 2011,  47–50). Others may consider PPP only for certain project types—as may be established in the PPP Policy (see PPP Program Scope). In many countries, the initial impetus to develop a project as a PPP is left to the discretion of the implementing agency.

To support this screening process, many governments introduce criteria or checklists for PPP potential against which projects can be compared. PPP Potential Screening Factors in South Africa provides an example of such a checklist from the South Africa PPP Manual (ZA 2004a). Similar criteria may be also used for more detailed appraisal, as described in Assessing Value for Money of the PPP—at the screening stage, the idea is to check if the criteria are likely to be met for the project to proceed to the next level of development.

The following resources provide further suggestions and guidance on the factors to consider when screening potential PPP projects:

  • India's online PPP toolkit (IN) includes a suitability filter that guides the user to consider the same issues described in PPP Potential Screening Factors in South Africa, as well as the support of the public sector for the project (including an assessment of the public sector capacities to implement the project as a PPP). It also considers potential barriers to project implementation (based on information from the pre-feasibility study) and other factors, such as the expected effort and resources needed to develop the PPP. For example, the availability of standard contracts should be assessed. 
  • In Colombia, the implementing agency must present an Executive Report to the PPP Unit, ANI, requesting authorization to implement the project as a PPP. The analysis in this report—such as pre-feasibility analysis—is described in the PPP Manual (CO 2014, 34–38).
  • The Government of Hong Kong's Guide to PPPs (HK 2007, 31–32) describes a list of criteria that a PPP should meet at the initial screening stage (or stage one business case) to be considered as a PPP candidate.
  • The Caribbean PPP Toolkit (Caribbean 2017, Module 3) provides guidance using Caribbean examples with global relevancy.

The UNESCAP Qualitative Value-for-Money Toolkit (UNESCAP 2017) contains a set of criteria that governments may use for prioritization and helps identify project weaknesses. Ministries, departments, or sector agencies often need support to overcome initial unfamiliarity or reluctance to adopt PPPs. A central PPP unit can play this role, as described in Dedicated PPP Units. Developing and implementing a PPP transaction is typically more expensive than the equivalent process for a traditional public investment project, which may deter agencies from identifying PPPs. Additional funding for PPP development can help level this playing ground. For example, the India Infrastructure Project Development Fund (IN 2013a) was established as a revolving fund, and can fund up to 75 percent of PPP project development expenses.

The outcome of this screening process is a pipeline of PPP projects set in the context of a national  infrastructure program and sector strategic plans. Making this PPP pipeline public can be a good way to build private sector interest in investing in PPPs. The Chilean PPP unit, Coordinación de Concesiones de Obra Pública, shares all relevant information on their project pipeline on their website. Farquharson et al describes the advantages of defining the investment framework for a PPP program—including the PPP pipeline and other planned infrastructure investments that complement it (Farquharson et al. 2011, 21–22).
