Key objectives included the creation of open-source tools for renewable energy data detection, high-resolution time series generation, and the development of user-friendly modelling workflows. Through six case studies, dissemination activities, and capacity building, OASES strengthened local capabilities and fostered long-term collaboration between Africa and Europe in renewable energy planning.enRenewable EnergyOpen Access DataOpen-Source SoftwareEnergy System ModellingAU-EU CollaborationCapacity BuildingWind and Solar EnergySatellite ImageryMachine LearningResource AssessmentTime Series GenerationScenario AnalysisSmart GridsOff-grid SystemsEnergy TransitionSustainable Energy SystemsEnergy Policy SupportData-Driven ModellingIRENA FlexToolWebGIS Visualizationreport
