Why Availability Payments Work
The availability payment model is the payment structure that makes P3 infrastructure delivery function in contexts where demand risk transfer to the private sector is inappropriate or unaffordable. Instead of the concessionaire earning revenue from users — and bearing the risk that those users will not appear in the numbers the financial model assumes — the government pays a service fee conditional on the asset being made available and performing to defined service standards.
The model elegantly separates the risks the private sector can genuinely manage (construction quality, lifecycle maintenance, operational performance) from the risks it cannot (user demand, which is driven by public sector service and policy decisions). A hospital P3 concessionaire has no control over whether the clinical services in the hospital attract enough patients to justify the facility’s size. They do have control over whether the facility is clean, well-maintained, and operationally available to deliver whatever level of clinical service the health authority chooses to provide. The availability payment pays for the latter. The clinical activity risk stays with the health authority.
How the Deduction Framework Works
The availability payment is not a fixed annual fee. It is a baseline payment subject to deduction when the facility fails to meet the performance standards defined in the contract. The deduction framework is the mechanism through which the payment structure creates operational incentives for the concessionaire.
Well-designed deduction frameworks share several characteristics. They are proportionate — the deduction for each performance failure reflects the severity of that failure’s impact on service delivery, not an arbitrary penalty that may be too small to motivate performance or too large to be commercially sustainable. They are certain — the concessionaire can calculate the financial consequence of any performance failure precisely, which allows them to make rational investment decisions about maintenance and operational staffing. They are focused — monitoring a small number of indicators that genuinely drive service quality produces better outcomes than monitoring a large number of indicators that create reporting burden without improving performance.
Poorly designed deduction frameworks produce predictable problems. If deductions are too small relative to the cost of compliance, the concessionaire will rationally choose to accept deductions rather than invest in performance. If deductions are too large, the concessionaire will adopt risk-averse operational strategies that reduce service flexibility and add cost. If the monitoring framework is too complex, disputes about measurement methodology consume governance resources that should be focused on service delivery.
The Response Time Trap
One of the most common deduction framework design errors is calibrating response time requirements to the availability of resources in a high-performing major city. A requirement to restore a failed HVAC system in a hospital to full operation within 4 hours might be achievable in London or Toronto, where specialist maintenance contractors are available 24 hours. In a remote location, or during extreme weather, or during a period of supply chain disruption, that same requirement may be structurally impossible to meet regardless of how capable and well-resourced the concessionaire is.
Deduction frameworks that do not account for location, access constraints, and supply chain realities produce deduction charges that the concessionaire disputes — correctly — as arising from conditions outside their control. The disputes consume governance resources. The relationship deteriorates. The contract’s commercial framework is undermined by provisions that were not designed for the actual operating environment.
Designing for Saudi Arabia’s Infrastructure Context
Saudi Arabia’s P3 program is deploying availability payment structures across a diverse portfolio of infrastructure types and geographic locations — from urban social infrastructure in Riyadh to remote industrial facilities in the Eastern Province. Calibrating deduction frameworks to the specific context of each concession — not importing frameworks developed for European urban programs and applying them to desert-climate, remote-location Saudi facilities — is essential for producing frameworks that actually incentivize performance rather than incentivize disputes.
The frameworks being developed for Saudi Arabia’s water sector — building on three decades of BOOT experience — provide a valuable starting point. The commercial discipline embedded in those frameworks, and the institutional knowledge of what works and what does not in the Kingdom’s operational environment, should inform the structures being developed for new sectors as the NPS expands P3 delivery beyond water into health, education, and transport.
