OnSSET is employed in projects with partner institutions across the world. Within these projects, detailed energy systems and integrated assessment models of several countries in different continents are continuously developed. Some of the existing models include the "Global Electrification platform", "Electrification Pathways for Afghanistan", "Energy System Development Pathways for Ethiopia", "Least-Cost Electricity Access Development Project for Madagascar", "Electrification Pathways for Benin", "Lighting the World" and "SweGRIDS". The models and projects involving OnSSET are described here.
