Overview

This is the documentation for the AETOS (Africa–Europe Energy Transition OSeMOSYS) model, developed under the RE-INTEGRATE project (Horizon Europe, Grant No. 101118217).

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. You can browse the source, submit issues, or contribute improvements.
