While the technical and economic benefits of combined heat and power (CHP) projects are well documented, the financing process is often misunderstood and frequently not given sufficient attention. CHP developers must navigate a complex landscape of project financing alternatives and provide detailed project information in order to attract investors.

This financing primer provides checklists of information that financiers need to evaluate CHP investment opportunities, and discusses how CHP developers can best tailor their financing approach to a specific project.
