OpenMod South Africa 2026 The Inaugural OpenMod Workshop on the African Continent Friday, 26 June 2026 | University of Cape Town, South Africa 🎫 Free to attend | 🎥 Sessions will be recorded and uploaded to YouTube About the Event Open Energy Transition and the Energy Systems Research Group from the University of Cape Town are proud to announce OpenMod South Africa 2026, the first OpenMod Workshop ever held on the African continent. Open-source energy system modelling has been evolving for years. It is already embedded in regulatory processes, power system planning, flexibility assessments, and investment analyses across Europe and beyond. The tools have matured. The community has grown. And now the conversation is coming to Africa. OpenMod South Africa will bring together researchers, system planners, utilities, regulators, developers, and students working at the intersection of energy, data, and climate to showcase what open modelling can do, share what it has already done, and build the foundations for a stronger African open modelling community. If open-source modelling is new to you, you are warmly welcome. This workshop is designed for all levels of experience. What to Expect ⚡ Lightning talks — concise presentations on tools, methods, and real-world applications 🖥 Technical demonstrations — live walkthroughs of open-source frameworks and case studies 💬 Breakout sessions — facilitated discussions on regional planning challenges and data gaps 🤝 Networking — structured and informal engagement across the full energy modelling community Call for Contributions We welcome contributions from practitioners, researchers, developers, and policymakers. If you would like to present a lightning talk, lead a technical demonstration, or facilitate a breakout session, you can indicate your interest in this form. Suggest your in person contribution May 29th, 2026 at the staging area 1 of the openmod forum describing your stall/lightning talk/breakout session. Submission deadline: 29th May 2026 Attendance All presenters and contributors are expected to attend in person. For general participants, in-person attendance is strongly encouraged as the workshop is designed to enable the kind of deep technical exchange and collaboration that only happens in the room. Organisers Tosin George and Max Parzen — Open Energy Transition Harro von Blottnitz and Gregory Ireland — University of Cape Town Questions? If you have any questions about the event, please contact Tosin at tosin.george@openenergytransition.org By completing this form, you confirm your interest in attending OpenMod South Africa 2026.

Openmod Workshop South Africa 2026 Openmod Workshop South Africa 2026 26 June 2026 • Cape Town, South Africa Openmod comes to Africa Open Energy Transition and the Energy Systems Research Group from the University of Cape Town are delighted to announce the inaugural Openmod Workshop in Africa, to be held at the University of Cape Town on Friday, 26 June 2026. Open-source energy system modelling remains underrepresented across much of Africa’s energy planning landscape. Openmod helps address this gap as a community-driven move...

At #Openmod2026 we’ll exchange ideas, tools, and applications for open energy modelling.
Join the #Openmod workshop after #IEW2026 and the IEA-ETSAP Summer Workshop week in Cape Town.

Without transparent energy planning, the lights could go out A team from Open Energy Transition discusses the benefits of open energy system modelling in assessing resources, including energy storage of varying durations.

Open models should be the standard in energy storage planning. We conducted a study with Form Energy showing that multi-day storage can cut curtailment, lower prices, and boost resilience.
