Summary: As the discourse on 100% renewable energy systems has progressed, energy system modelling tools have been developed to demonstrate the technical and economic feasibility of fully sustainable energy systems. This paper examines two such models, the LUT Energy System Transition model and the EnergyPLAN simulation tool, and analyzes various modelling approaches used by researchers. The results indicate a dominant role for solar PV in the energy system, but limitations in EnergyPLAN's sector coupling capabilities make it more costly compared to the LUT model. Additionally, the study finds that high transmission does not add much value in countries with abundant solar resources.
