GDESSA - Gridded Dataset for Electrification in Sub-Saharan Africa, 2021 update

This high-resolution electrification dataset for Sub-Saharan Africa is developed at the Energy Program of the International Institute for Applied Systems Analysis (IIASA) in cooperation with the Fondazione Eni Enrico Mattei (FEEM).

The online interface allows browsing the (estimated) population without electricity access between 2014 and 2020, as well as the predicted electrification rates at the province-level and the estimated tiers of electricity access quality for those with access to electricity. The interface is developed with Google Earth Engine, and embeds the familiar features of Google Maps including switching from map to satellite view and looking for cities and places.

In this interface, the datasets are visualised at a 1 km resolution to optimise speed. At the data repository a very high-resolution (30 meter) version is available for use in Google Earth Engine. The data can be retrieved from The source code and user guide for replicating, editing, and updating the data is found at Github:

The Nature Scientific Data paper presenting the methodology and the validation of the dataset is found at The One Earth Analysis paper can be found at:
