Planning and Prospects of Renewable Power in Africa

System Planning Test (SPLAT) capacity expansion models are a key component and product of IRENA’s support to African countries. Built using the MESSAGE software, the agency has developed SPLAT models covering 47 African countries across the five African power pools. These models form the basis of IRENA's Planning and Prospects for Renewable Power in Africa report series. The dashboard below gives an initial overview of IRENA SPLAT model results and the range of scenarios modelled with them to date.



To view detailed model outcomes, the complete set of SPLAT dashboards can be accessed at the link below. These dashboards are equipped with a user-friendly interface to explore results at country or regionally-aggregates levels and across any specific scenario. The underlying database is continuously maintained with any updates from recent work.

Note: Different methodologies, assumptions and scenario definitions have been employed for different models. The user should refer to the definitions in the related reports to ensure correct usage of the data featured in SPLAT dashboards. The underlying analyses build on IRENA’s insights into renewable resource availability, technology costs and performance characteristics. The retirement schedule of current generation capacity fleets, as well as committed project pipelines at the time of the analyses, are also taken into consideration. The power systems modelled are optimised over the modelling horizon according to cost minimisation principles, subject to physical energy flow and operation constraints. Optimisation is performed at the regional level, i.e. for a power pool with its member countries treated as a homogeneous entity. The optimisation results may or may not be substantially different from the optimal power mix for a single country when trade is not considered. Non-renewable features of power system development were calibrated according to official regional power pool masterplans, when available.
