Because PPP contracts span decades, the signing of the agreement is merely the start of the operational relationship. Sponsoring government agencies must establish a dedicated Contract Management Team to monitor the SPV’s performance against pre-agreed Key Performance Indicators (KPIs) and output specifications.

In availability-based models, if the private partner fails to meet performance or quality standards, the contract manager applies automated financial penalties called Performance Deductions:

[ SPV Fails to Meet Quality / Availability KPI ] 
                       |
                       v
[ Contract Manager Calculates Points Deduction based on Severity ]
                       |
                       v
[ Automated Reduction applied to the next Monthly Availability Payment invoice ]

Over a 30-year span, changes in macroeconomic variables, legal frameworks, or unexpected geological conditions often trigger contract disputes or requests for renegotiation. Contracts must outline clear dispute resolution frameworks, prioritizing step-by-step mitigation: Independent Expert Determination, formal Mediation, and finally, international binding Arbitration. Unregulated contract renegotiations must be avoided, as they can compromise transparency and shift commercial risks back onto taxpayers.
