Project financing has become widely used in India for large capital intensive infrastructure projects. It involves borrowing funds for a project before construction is complete, with lenders looking primarily to the project's cash flows and assets for repayment rather than the sponsor's balance sheet. Key to project financing is allocating risks through long-term contracts between the project company, construction firms, fuel/offtake suppliers and operators. Project financing emerged in the 1970s for power projects and has since been used for various industries like mining, transportation and manufacturing.
