Where the project company's revenue source is to be generated from the tariffs collected from consumers in a given area, or where the rate of use of services consumed dictates a part of the payment stream, the project company may seek an exclusive mandate to provide the services within that area. This may be difficult for the grantor to accept where it wishes to cultivate competition and create as realistic a free market as possible. The grantor will need to consider carefully the issue of exclusivity and where exceptions to such exclusivity might arise.
