AbstractSudan is a sunbelt country that has abundant solar resources and large wasteland areas, especially in the northern and western portions. Concentrating solar power (CSP) technologies are proven renewable energy (RE) systems to generate electricity in neighboring countries from solar radiation and have the potential to become cost-effective in the future. Most of the attention is given to solar photovoltaic (PV) systems; no thorough techno-economic study has been carried out to evaluate the potential for CSP technologies in Sudan. The main aim of this paper is to encourage Sudan's authorities to pursue CSP technologies and overcome the associated challenges. The study used techno-economic analysis for two of the most mature CSP technologies – solar power tower (SPT) and parabolic trough (PT) technology – to produce electricity in Sudan. Two commercial CSP plants, namely GEMASOLAR and ANDASOL-1, have been “hypothetically” relocated in six Sudanese zones using the system advisor model (SAM). These zones were scrutinized based on a rigorous technical CSP site assessment study. The results indicate that the nominated zones outperformed the original Spanish plants in terms of energy outputs, capacity factors (CF), and levelized cost of energy (LCOE). The Northern state has two zones near Wadi-Halfa that are most suitable for installing CSP systems, with the SPT system offering better outcomes than the PT. This study proposes a 5 MWe SPT pilot plant with optimum specifications, enabling decision-makers to take further actions. It also recommends some actions to promote this sector and meet the 2030 and 2050 RE targets.
