Demand Risk

Demand risk is one of two principal components of the operating risk that must be transferred to a concessionaire for a contract to qualify as a concession under EU and UK procurement law. It is the most commercially significant risk for operators in infrastructure and public services markets, because it exposes the private party to the full force of user behaviour, demographic change, competing services, and economic cycles over multi-decade contract terms.

What is Demand Risk?

Demand risk is defined in Directive 2014/23/EU (Recital 18) as the risk that actual demand for the works or services will differ from what was estimated at the time of award. If a concessionaire earns revenue from users and those revenues are lower than projected because fewer people use the service, the concessionaire absorbs the financial shortfall. That is demand risk sitting squarely with the operator.

Demand risk can arise from many sources. Traffic volumes on a toll road may be lower than forecast because of economic recession, remote working habits, fuel costs, or competing routes. Passenger numbers at a car park may fall because of urban cycling investment or changes to local planning policy. Users of a leisure centre may decline because of demographic shifts or competing private facilities. None of these are within the concessionaire's control, and all of them directly affect revenue from users under a demand-risk model.

Demand risk must be genuine and substantial to satisfy the operating risk transfer requirement of Directive 2014/23/EU. If the contracting authority guarantees minimum usage revenues, or compensates the concessionaire whenever actual usage falls below a floor, the arrangement may not qualify as a true concession. The guarantee must not be so generous as to eliminate real financial exposure.

Demand risk is distinct from availability risk, which concerns the risk of performance deductions when the concessionaire fails to deliver the required output standard. Some concessions transfer only one type of risk; the best-structured concessions transfer both, calibrated to the nature of the asset and the market.

Why demand risk matters for bidders

Demand risk is the central financial modelling challenge in any concession bid. Bidders must project revenues over the full concession duration, which may be 20, 30, or even 40 years, and demonstrate to their lenders that the project is financially viable even under stressed demand scenarios. Project finance lenders typically require a base case, a downside case, and a severe downside case, each with supporting traffic studies, population projections, or market analyses depending on the sector.

Bidders must also understand the contractual mechanisms that modulate demand risk. Some concession contracts include minimum revenue guarantees, traffic risk-sharing bands, or ratchet mechanisms that adjust concession fees or the concession term in response to demand outcomes. These mechanisms shift part of the demand risk back to the authority, and their presence must be factored into both the financial model and the legal classification of the contract.

Example

A Swedish municipality awards a 20-year services concession for two municipal swimming pools. The concessionaire charges entry fees, which it keeps. If swimming participation falls because of new private fitness clubs opening nearby, the concessionaire's revenues fall and it bears that loss. The authority pays no subsidy. This is a clean demand-risk transfer. Compare this with a structure where the authority guarantees to pay EUR 800,000 per year regardless of visitor numbers: in that case, the demand risk has been largely re-absorbed by the authority and the arrangement requires re-examination of its concession classification.

Frequently Asked Questions

How is demand risk modelled in a concession bid?

Bidders typically commission independent traffic studies, footfall analyses, or market demand reports to support their revenue projections. The base case is presented to lenders as the expected scenario; the downside case tests whether the project can service its debt under adverse conditions. Sensitivity tables showing the impact of 10%, 20%, and 30% demand shortfalls on financial ratios are standard in project finance documentation for European concessions.

Can demand risk be shared between the authority and the concessionaire?

Yes. Many European concessions use risk-sharing mechanisms such as revenue bands (the authority absorbs risk below a floor, the concessionaire absorbs risk in the middle band, and revenues above a ceiling are shared), minimum volume guarantees for a defined period, or extension mechanisms that increase the concession duration if demand falls. Provided the concessionaire still bears substantial exposure in the risk-sharing band, the contract may still qualify as a concession.

Does demand risk apply to availability-based concessions?

Availability-based concessions, such as some hospital or school PPPs, transfer availability risk but not demand risk in the traditional sense: the authority pays based on whether the asset is available and performing correctly, not based on how many people use it. These may still qualify as concessions if the availability deduction mechanism is severe enough to create genuine financial exposure for the concessionaire.
