The exact nature of the services to be provided by the project company differentiates projects and provides specific understanding of the commercial and technical risks likely to be encountered by the project company. For example, two different PPP projects may allocate to the project company the task of managing power distribution in a given area. However, one PPP allocates all management functions while the other relates only to billing and collection. It would be possible to devise a model that would differentiate even the most subtle differences in scope of work; however, such a model would be too complex to be useful. For this reason, the detail of the scope of work demanded of the project company is not included in this model.
