Abstract: Tracking the Open-Source Energy Modelling Ecosystem: Insights for Smarter Tool Selection There is a vast ecosystem of open source energy system modelling tools, but navigating and comparing them remains a challenge for practitioners, researchers, and developers. This session introduces platforms designed to help users explore available tools, understand their development communities, and make more informed tool selection decisions. In this presentation, Bryn Pickering introduces the Open Energy Modelling Tool Tracker (openmod-tracker), a platform that aggregates repository and community data from more than 200 open source energy system modelling tools. The session explores how repository activity, contributor engagement, documentation availability, and other development metrics can help users identify tools with strong community support and ongoing development. The presentation also covers a complementary feature comparison platform designed to help practitioners evaluate tool capabilities and identify feature gaps. Bryn discusses how these platforms can support the adoption of open source tools for energy system planning, improve transparency in tool selection, and encourage collaborative development across the energy modelling ecosystem. Speaker: Bryn Pickering Bryn Pickering is a Senior Energy Modeller at Open Energy Transition and lead developer of the Calliope energy system modelling tool.
