Public-Private Partnerships (Ppp): Structure, Risk, and Defense

Public-Private Partnerships are implemented through three primary structural models: the concession agreement, the Build-Operate-Transfer (BOT) structure, and the availability payment model. A concession grants the private party the right to build, operate, and collect revenues from the project for a defined period. Developers and government authorities evaluating PPP structure should seek public-private partnerships legal counsel to assess which model aligns with the project's risk profile, financing requirements, and regulatory framework.

The PPP agreement must address termination for convenience by the government, step-in rights, payment deductions when performance standards are not met, and the private party's design, construction, operation, and maintenance obligations across the life of the project. The PPP agreement must also address the interface between the project and any government-provided assets, services, or permits on which the private party depends. Private parties and government contracting authorities entering PPP agreement negotiations should seek infrastructure finance legal counsel to structure the core provisions and allocate each identified risk to the party best positioned to manage it.

The private party in a PPP agreement manages construction risk through the EPC contract with the construction contractor, performance bonds, and delay liquidated damages. Construction and completion risk, including cost overruns, schedule delays, and latent site conditions, is allocated almost entirely to the private party in mature PPP markets. Private parties in PPP agreements should seek construction contracts legal counsel to evaluate the risk allocation framework and ensure that the contract transfers to the private party only the risks it can price and manage effectively.

Most large PPP projects are financed on a limited recourse project finance basis, in which the debt is repaid from the project's cash flows rather than from the general assets of the private party's sponsors. Limited recourse project finance requires the lenders to be satisfied that the PPP agreement provides sufficient cash flow certainty, adequate security over the project assets and revenues, and step-in rights that allow the lenders to take over the project if the private party defaults. Private parties and project lenders structuring PPP financing should seek construction and engineering law legal counsel to ensure the financing structure is consistent with the PPP agreement's step-in rights, cure periods, and termination payment provisions.

Public-Private Partnerships are subject to government procurement regulations that govern how the private party is selected, what information must be disclosed to competing bidders, and how the contract can be modified after award. In the United States, federal PPP projects are governed by the Federal Acquisition Regulation and agency-specific procurement regulations. Government authorities and private parties pursuing PPP project awards should seek municipal law legal counsel to evaluate the applicable procurement framework and structure the procurement process to withstand challenge.

The availability payment mechanism is designed to incentivize the private party to maintain the project asset in the condition required to earn the full payment. The government applies deductions to the availability payment when the asset or a defined portion of it is unavailable due to the private party's failure to meet the performance standards. Private parties managing availability payment disputes should seek government contract disputes legal counsel to evaluate the deduction calculation, challenge incorrect government determinations, and assess whether the deduction level creates termination risk.

The regulatory environment in which a PPP project operates can change significantly over a thirty-year contract term. Changes in environmental standards, safety regulations, tax policy, and sector-specific regulatory requirements can impose costs on the private party that were not anticipated at financial close. Private parties in long-term PPP agreements should seek construction litigation legal counsel to evaluate the change in law provisions, identify uncompensated regulatory risks, and assess treaty protection options for cross-border investments.

PPP agreements typically establish a tiered dispute resolution process that begins with senior management negotiations, proceeds to expert determination for technical disputes, and culminates in arbitration for legal disputes that cannot be resolved by expert determination. International PPP projects commonly specify ICC or UNCITRAL arbitration, with a seat in a neutral jurisdiction. Parties in PPP agreement disputes should seek procurement fraud legal counsel to evaluate the termination provisions, assess compensation entitlement, and develop an enforcement strategy that preserves the project's commercial value.
