What is a public-private partnership?

A public-private partnership (abbreviated as P3 or PPP) is an agreement, usually creating a lasting relationship, between a private party and public entity to share the risk and rewards of delivering or enhancing an essential public service. Often the project is one whose economics or feasibility is dependent upon, or greatly enhanced through, collaboration.

Types of public-private partnerships

Public-private partnerships should be considered when a government entity is pursuing economic development or planning improvements relating to its core function of promoting health, safety, and welfare. Often, these objectives are intertwined.

Successful public-private partnerships have several key points in common:

  1. The public entity has clearly identified and quantified the project’s fiscal and community impacts (including opportunity costs) and has community and political support.
  2. The public entity has assembled a team that can help the municipality make decisions regarding assessing project feasibility, identifying financial options to secure an equitable agreement, managing predevelopment work, and overseeing design, construction, closeout, and occupancy.
  3. The public-private partnership objective, a shared goal between the public and private entity, is well defined and agreed upon in the deal agreement.

Tips for structuring a public-private partnership

Public-private partnerships may not be right for every development project, but many communities have found success by following these tips:

Tip #1: Get an experienced advisory team on board right away

From a public perspective, there are unique considerations that should be analyzed in order to set a project up for success, including deal structure and revenue opportunities. Additionally, there are other qualitative factors that make a public project successful when partnering with a private partner, such as transference of risk, access to capital, speed of delivery, and development expertise. A development advisor can help municipalities think through all these considerations and confirm their goals and objectives are feasible based upon underlying factors.

Tip #2: Understand the risks vs. rewards

While a public-private partnership allows the municipality to transfer project risk to the private partner, leverage innovative design and construction techniques, free up capital for other purposes, and keep project debt off the books, there are some challenges or risks as well. Public-private partnerships sometimes have higher financing costs, the procurement process can be complex, and the deal agreement may limit flexibility. A development advisor will be able to help the municipality identify the advantages and disadvantages of a potential public-private partnership.

Tip #3: Understand the private-sector perspective

Municipalities should look at any project through both a private and public lens to ensure that it is beneficial, fair, and viable for both sides of the deal. Typically, private entities are focused on the financial benchmarks and returns, such as return on cost, return on equity, and internal rate of return. In addition to these metrics, the private partner will want to assess construction budgets, operating expenses, revenue projections, and debt service capacity to determine a project’s feasibility. Understanding the importance of these considerations to the private partner helps municipal stakeholders understand the private partner’s motivations and risk tolerances.
