Figure 1. UNNZ Scenario Electricity and Gas Trade within Europe and Africa.
The **Africa–Europe Energy Transition OSeMOSYS (AETOS)** model is a multi-country, open-source energy system model that explores long-term energy pathways and trade between Africa and Europe. It extends and integrates the **OSeMBE (Europe)** and **TEMBA (Africa)** frameworks, providing the most detailed representation to date of national power systems, intra-continental trade, and cross-continental grid interconnectors and gas pipelines. AETOS is designed to analyze how Africa and Europe can transition toward net-zero energy systems while considering electricity and natural gas trade. The model enables researchers, policymakers, and analysts to explore scenarios that capture infrastructure investments, policy pathways, and sustainability targets across **78 countries**. Key Features ------------ - **Geographic coverage**: 48 African countries and 30 European countries (incl. Finland, UK, Switzerland) each modeled individually. - **Time horizon**: 2021–2055 annual analysis. - **Demand coverage**: National electricity generation and gas demand (other sectors such as transport, buildings, and services not explicitly modeled yet). - **Energy trade representation**: Grid interconnectors, Natural Gas pipelines, LNG infrastructure. - **Units & currency**: Capacities in GW, fuel flows in PJ, emissions in MtCO₂, and all costs in constant 2021 USD. Finding the GitHub Repository ----------------------------- All model code, data-processing scripts, and workflow tools are openly hosted in the `AETOS GitHub repository
