This document provides an overview of project finance and the credit appraisal/evaluation process for infrastructure projects. It defines infrastructure projects and examples. It also defines project finance as financing that is "non-recourse" where lenders are only repaid from the project's cashflows. The credit appraisal process for infrastructure projects focuses on assessing the technical, economic, financial, and commercial viability of projects, with an emphasis on evaluating the project's feasibility study and ability to service debt from cashflows rather than relying on sponsor balance sheets. Key areas of analysis include market demand, costs, financing plan, cashflow projections and sensitivity analysis.
