The Input Supply Agreement obliges an input supplier to deliver to the private partner/project company a specified quantity of input necessary to the operation of the project, at a certain level of quality. This agreement allocates the market risk involved in the price and availability of the input. The Input Supply Agreement is only required where some supply of input is necessary for the operation of the facility. An example is the fuel supply agreement between Coal India Limited and various power companies obliging Coal India to supply coal to them.
