Public-Private Partnerships (PPPs) are a crucial contractual mechanism for meeting growing infrastructure needs while optimizing the use of public and private resources. Their success relies primarily on rigorous and strategic risk management, which must be identified, assessed, and optimally allocated among stakeholders based on their capacity to manage them. This balanced allocation aims to minimize the overall cost of the project over its lifecycle, while ensuring efficient access to private financing. However, a rigorous and transparent valuation of the transferred risks is essential to justify the additional cost inherent in the private partner's risk-taking. The comparative study of two emblematic cases the failure of the Cross City Tunnel in Australia, marked by poor anticipation of financial, social, and political risks, and the success of the Kita solar project in Mali, illustrating exemplary proactive and contractual risk management highlights the importance of fine-tuned contractual engineering and appropriate governance. Lessons learned highlight the need to integrate dynamic adjustment mechanisms, effective social communication, and continuous risk monitoring. This integrated approach is essential to ensure the financial viability, social legitimacy, and operational sustainability of PPPs, particularly in strategic sectors such as energy .

1.      Introduction

In a context of increasing budgetary constraints and significant infrastructure needs, Public-Private Partnerships (PPPs) are emerging as a strategic solution allowing States to mobilize private sector financing and expertise to guarantee efficient and sustainable public services. Their success, however, depends on rigorous contractual engineering, including proactive and effective risk management. Unlike traditional public procurement where the State bears the majority of risks, or public service delegations which transfer almost all of these risks to the private sector, PPPs are based on an optimal allocation of risks according to the capacity of each party to manage them. This approach aims to reduce the total cost of the project over its life cycle, while requiring an accurate, transparent and economically justifiable valuation of the transferred risks, otherwise the efficiency and financial attractiveness of the project could be compromised [1] . Furthermore, a common bias in the comparative evaluation of contractual options is the underestimation of the risks retained by the State in traditional approaches, which distorts decisions in favor of or against the PPP, particularly in the absence of rigorous quantification in comparative value analyses (public sector comparator ) [1] . This work aims to provide technical and critical insight into risk management in PPP projects, based on the comparative analysis of two real and contrasting practical cases. The study pursues three main objectives: (i) to identify the different categories of risks involved in PPP arrangements, according to their nature, origin and potential impact; (ii) to analyze the consequences of poor transfer, inaccurate assessment or deficient management of these risks; and (iii) to formulate operational recommendations aimed at strengthening the robustness of contractual arrangements and improving the institutional capacities of the parties involved.

The methodological approach adopted combines a critical review of international literature, an in-depth analysis of existing projects illustrating respectively a case of failure and a case of success, as well as a review of good practices in contractual structuring, risk governance and coordination between stakeholders. This method makes it possible to highlight the success factors and pitfalls to avoid in risk management in a PPP context.

This study is structured around five main axes: it begins with a presentation of the conceptual and legal foundations of Public-Private Partnerships (PPP), continues with a typology of the risks associated with these projects, then offers a critical analysis of an emblematic case of failure (the Cross City Tunnel in Sydney), before examining an example of success (the Kita solar project in Mali), and finally concludes with a summary of the lessons learned and practical recommendations for stakeholders.

2.      Classification and identification of risks in PPPs

To ensure proactive and controlled risk management, risks must be identified, classified and assessed according to several complementary dimensions [2] :

• Origin of risks: social, external, organizational, political, economic, natural, managerial, technical, financial, or resource-related.
• Probability of occurrence: low, medium, high, very high.
• Severity of impact: minor, acceptable, significant, critical, tragic.
• Nature of the consequences: additional execution costs, financial losses linked to the economic situation, environmental impacts, and other consequences specific to the context of the project.

This multidimensional approach makes it possible to refine management, clarify the distribution of responsibilities and increase the resilience of projects in the face of internal and external hazards.

3.      Case study: Risk analysis in the Cross City Tunnel project (Sydney)

The Cross City Tunnel experience highlights several major dysfunctions in the risk management of a PPP, the impacts of which could have been mitigated by better planning and rigorous anticipation [3] .

• Financial risk: Significant underutilization of infrastructure is primarily due to an overly high toll rate, set to ensure a 16% private return over 30 years and finance a $105 million government levy. The lack of a rate adjustment mechanism in the event of lower-than-expected ridership reflects an incomplete initial assessment of financial viability.
• Risk of social acceptance: The imposed reorganization of the road network aimed at channeling traffic towards the tunnel has aroused significant public opposition, with a feeling of imposition of a financial burden for a previously free service, affecting the social legitimacy of the project.
• Political risk: The perception of a priority fiscal purpose, via the monetization of the concession through an access tax, has eroded institutional trust and raised questions about the real objective of the PPP.

Related risks such as lack of cash payment, higher cost for users without e-tag, environmental concerns related to emissions in the tunnel, lack of contractual transparency and inadequate signage have also aggravated the situation [3] .

4.      Requirements for effective risk management in PPPs

Lessons learned from the Cross City Tunnel show that the success of PPPs depends on:

• Early and comprehensive identification of potential risks.
• The establishment of dynamic adjustment mechanisms, particularly pricing, to adapt to operational realities.
• Sensitive social management aimed at preserving public acceptability through upstream dialogue and consultation.
• Transparent governance ensuring trust between stakeholders and clarity of responsibilities.

The absence or weakness of these elements can permanently compromise the economic viability, social legitimacy and political stability of the project [2] [3] .

5.      Positive illustration: Proactive risk management in the Kita solar project (Mali)

5.1.   Context and choice of the PPP BOOT model

In a context of major energy challenges and weak public financial capacities, the Kita solar project (50 MW) adopted a PPP model in Build - Own - Operate - Transfer (BOOT) mode in order to ensure optimal private financing, transfer risks to the private sector, and align the project with the objectives of the Malian national energy policy aiming for 25% renewable energy by 2033 [4] [5] .

5.2.   Methodical approach to risk management

In accordance with international best practices and ISO 31000 standards, the project adopted a structured approach integrating:

• Identification rigorous assessment of 47 risks .
• A systematic assessment of probabilities and severities, with an average level of severity at 12.6% and 32% of risks deemed critical.
• A balanced contractual distribution: 49% of risks allocated to the public sector (political, legal, commercial), 36% to the private sector (financing, construction, performance), and 15% shared (social, environmental, force majeure) [6]

5.3.   Six-phase process for dynamic and sustainable management

The following table illustrates the six-phase process for dynamic and sustainable risk management, applied to the Kita Energy Project as a Public-Private Partnership (PPP) model. It highlights each step  from risk identification to continuous monitoring and how it was concretely implemented.

Table: Lifecycle Risk Allocation and Mitigation – Example of the Kita     Energy Project

Phase	Description	Application to the Kita project
1. Risk identification	Comprehensive inventory of potential threats	47 risks identified
2. Risk assessment​	Rigorous analysis of probability and severity	Average of 12.6%, 32% judged critical
3. Risk allocation​	Optimal allocation to the best-placed parties	49% public, 36% private , 15% shared
4. Risk Mitigation​	Implementation of targeted measures	Transfer of technical risks to the private sector
5. Formalization contractual	Legal integration into the BOOT contract	Complete life cycle coverage
6. Monitoring and continuous review	Monitoring and adjusting strategies	Proactive management strengthening bankability

 

This approach made it possible to optimize the bankability and sustainability of the project, while ensuring consistency with national energy development objectives [6].

6.      Lessons to be learned for the success of PPP projects

• Prioritize a complete and multidimensional identification of risks, taking into account their origin, probability, severity and specific consequences.
• Establish a clear and contractual allocation of risks, entrusting each risk to the party best equipped to manage it, thus avoiding conflicts and additional costs.
• Integrate dynamic adjustment mechanisms, particularly in terms of pricing, to compensate for gaps between forecasts and operational realities.
• Ensure proactive social management and communication, promoting acceptability and minimizing local opposition.
• Ensure transparency and solid governance, enabling trust to be built between public and private partners and with users.
• Adopt a continuous monitoring and review approach, with appropriate management tools to react quickly to changes in the context.
• Systematically include rigorous risk assessment in economic analysis to avoid comparative bias and optimize decision-making.

7.      Conclusion

The cross-analysis of the Cross City Tunnel project and the Kita solar project clearly illustrates that risk management is a determining factor in the success or failure of PPPs. Failures related to poor anticipation of financial, social, and political risks can be avoided through a methodical, integrated, and transparent approach. Robust governance, combined with balanced risk allocation and flexible adjustment mechanisms, guarantees the financial and operational sustainability of projects, as well as the satisfaction of stakeholders' expectations. These lessons provide a solid basis for guiding the structuring of future PPPs, particularly in strategic sectors such as energy, where development and sustainability issues are major.
