Impact information

Applies to investments made from 2019 onwards. The tabs in this section define what we expect to achieve through the investment, assessing the potential impact of the investment against six dimensions of impact. You can find more details on our methodology of assessing impact here.

The ultimate impact is Increase the country’s installed power capacity and provide a large proportion of its annual output, particularly during the dry season which has traditionally been the season with the lowest hydropower production but the highest demand,hence reducing reliance on imports and thus improving energy security.


Primary Secondary

Support greenhouse gases (GHG) emission reductions by expanding renewable energy capacity to avoid increased reliance on thermal based generation.

Demonstrate bankability to private sector investors through creating a model for future investment in the hydropower sector. The Project’s PPA framework is expected to be utilized as a template for future investments for the hydro sector.
