The government may decide to provide direct support for the project for example through subsidies/grants, equity investment and/or debt. These mechanisms are particularly useful where the project does not in its own merit achieve bankability, financial viability or is otherwise subject to specific risks that the private investors or lenders are not well placed to manage. In developing countries where private finance is most needed, these constraints may necessitate more government support than would be required in more developed countries.
