Despite the considerable energy problem in Africa, it is not clear how the proliferation of regional power pool (RPPs), as the most feasible solution, address the problem by fostering energy cooperation. The main research objective was to analyse and compare the role of RPPs, particularly the Eastern and Southern African power pools (EAPP and SAPP), in fostering energy cooperation and addressing energy security in their respective sub-regions. The study employed a mixed research design. The study targeted 100 leaders and senior experts from the EAPP, SAPP, regional economic communities, financial institutions, scholars, the African Union (AU), and the United Nations. Qualitative data were analysed thematically, while quantitative data was analysed via descriptive and inferential analysis. Simple linear regression models were used to test the hypotheses. From the finding, in Eastern Africa, weak power pool arrangement, EAPP, has contributed significantly to the prevailing energy insecurity ( =.345, p<.05); on the other hand, strong regional power pool in Southern Africa, SAPP, significantly contributes to energy security ( =.323, p< .05), thus depicting that strong RPP is a key predictor of energy security in the region. Based on the findings, the study concludes that the institutionalised attempt to energy security in Africa can address most of Africa’s energy security challenges. However, Africa must embrace the role of these energy security institutions by pursuing a deliberate policy to strengthen them so that its overall integration project, as stipulated in the African Union Agenda 2063, can be materialised.   Received: 12 August 2021 / Accepted: 13 October 2021 / Published: 5 November 2021

&lt;p&gt;Ensuring reliable supplies of energy and water are two important Sustainable Development Goals, particularly for Sub-Saharan African countries. The energy and water challenges are however not independent, and the interlinkages between them are increasingly recognized and studied using water-energy nexus approaches. Yet, most of existing modeling tools are not accurately reproducing this nexus and thus provide limited support to the design of sustainable development plans.&lt;/p&gt;&lt;p&gt;In this work, we contribute an integrated modeling approach by embedding the hydrological description of the Zambesi River Basin into an energy model of the Southern African Power Pool (SAPP). The SAPP is the largest African power pool in terms of installed capacity and coordinates the planning and operation of the electric power system among the twelve member countries (Angola, Botswana, DRC, Lesotho, Malawi, Mozambique, Namibia, South Africa, Swaziland, Tanzania, Zambia, Zimbabwe). Specifically, we use the Calliope energy model, which allows to form internally coherent scenarios of how energy is extracted, converted, transported and used, setting arbitrary spatial and temporal resolution and time series input data. As in many state-of-the-art energy models, hydropower production is poorly described by neglecting the water availability constraints and assuming hydropower plant produce at their nominal capacity in each timestep. Exploiting Calliope existing modeling components, we improved the hydrological description of the main reservoirs in the Zambezi River Basin as part of the overall SAPP model, namely Ithezithezi (120 MW), Kafue Gorge (990 MW), Kariba (1.8 GW) and Cahora Bassa (2 GW). Our improvements include the most relevant hydrological constraints, such as time-varying water availability as determined by inflow patterns, time-varying hydraulic head, evaporation losses, cascade releases and minimum and maximum storage value. The model outcomes, such as the &amp;#160;storage timeseries of each reservoir and the power production by source of each country, are then evaluated for different hydrologic scenarios. Our results are expected to demonstrate the value of advancing the hydropower characterization in energy models by capturing reservoir dynamics and water resource availability. These improvements will be particularly valuable to support hydropower expansion in African countries that rely mostly on hydropower to satisfy their growing energy demand.&lt;/p&gt;
