Finance and investment

Despite the strong demand for clean energy and an abundance of capital available worldwide, securing favourable financing arrangements for hydropower development is a challenging and complex task, which needs to be specifically tailored for each project.

The reasons for this are multidimensional as financing is contingent on a variety of factors, such as hydrology, and environmental and social considerations, which impacts a project’s risk-reward profile.

Preparation facility model

A significant barrier to private sector investment in hydropower is the financial risk associated with rigorous and complex planning and assessments, with no certainty for investors that a project will be given permission to proceed.

We are promoting a new hydropower project preparation facility model, which could help investors, developers and governments get new projects off the ground, by ensuring that each one is selected according to recognised sustainability criteria and national and regional development needs. Read more.

Green bonds

An innovative new investment instrument, green bonds are fixed income loans for the finance and refinance of projects and assets that help address environmental and climate risks. 

We are working with partners to agree recognised eligibility criteria for green bonds to fund hydropower projects. Read more.
