The SPLAT model provides a least-cost optimization framework for energy supply, on the basis of the MESSAGE software from the International Atomic Energy Agency (IAEA). SPLAT models are calibrated for national/regional analysis with the respective country/regional input data. The configured models allow decision makers to assess least-cost investment options in light of specific policy goals, such as targets set for increased renewables penetration, reduced import dependency, improved affordability or in the context of NDCs. For development and refinement of the model IRENA engages practitioners and experts to identify best practices in energy modelling, policy-relevant insights, key planning components, design guidelines and integration strategy development.

IRENA developed regional analyses of renewable energy prospects for all five African power pool regions (West, Southern, Eastern, Central, North). In 2016, IRENA launched a synthesis report, Africa Power Sector: Planning and Prospects for Renewable Energy, that captures the IRENA regional analysis for all five African Power Pool regions. Detailed power sector assessment for African regions was also provided in the IRENA report Africa 2030: Roadmap for a Renewable Energy Future of 2015. The regional planning reports based on the SPLAT models are found in the following links:

IRENA has recently updated the SPLAT model for the Africa Clean Energy Corridor (ACEC) region that covers Southern Africa and Eastern Africa; the upcoming report includes an updated database for the ACEC, and an analysis of high-potential zones for solar PV and wind-based power generation. IRENA is also updating its SPLAT models for Central Africa, and the respective regional planning report is under development.

As an integral part of the regional analysis and national master plan support, IRENA has undertaken energy planning trainings at regional and national level, including in West Africa,  Eswatini and Sierra Leone. Trainings focus on the development and application of the calibrated SPLAT models, for defining and running energy planning scenarios, and for developing a national Energy Masterplan document. The energy planning trainings serve to enhance user knowledge and ownership of energy planning tools, and to enable countries to independently maintain and expand their national model for long-term planning.
