Decentralized rural electrification in Kenya: Speeding up universal energy access

This paper undertakes a comprehensive spatial mapping of the existing energy infrastructure in Kenya. With the perspective of the current energy status and local resources, the study develops a rural electrification spatial model for Kenya (RERUKE tool) to identify optimal strategies for the different locations. The model considers the potential of conventional approaches (diesel gensets), clean technologies (solar, wind, hydro mini-grids), hybrid systems and the option of central grid extension to electrify remote areas in Kenya at the lowest possible cost. The model output is contrasted to the national Rural Electrification Master Plan (REM) of Kenya. While both the REM and RERUKE tool target the off-grid rural electrification options, their methodological approaches are intrinsically different. The comparison between both results aims to enable valuable synergies and highlight the potential complementarities that can create added value for stakeholders involved in rural electrification planning. In particular, RERUKE model output highlights the substantial role that renewable energy systems can play in decentralized generation providing universal energy access to rural households at a competitive cost.
