The customers are users of the goods or services provided by the infrastructure project. Depending on the project, the customers may be the general public, the government or the business sector. The customer may also pay tariffs for the goods and services, or receive the goods and services for free or at a subsidised rate. Where the customers are the general public, they are not likely to be directly involved in the negotiations and terms of the project. Therefore the government in this case, would need to set or negotiate with the project company in relation to the tariff structure for the infrastructure services. Where the customer is the government or a private business that has an interest in completing the project, the customer may need to commit to certain agreements to purchase or pay for the infrastructure services (See Off-take agreements). Lenders will often require conditional assignments of these Off-take agreements as security.
