2026.04 TESPy community meeting

Last week the second TESPy Community Meeting, held in Braunschweig, was a resounding success, offering developers and users an excellent opportunity to exchange ideas in person, discuss new concepts, and collaborate on the further development of TESPy.

The highlight of the meeting was the hackathons, during which participants worked intensively on various topics:

  • Introductory tutorials for TESPy
  • Best practices for initial values in automated simulations
  • Creation of a ModelTemplate class, which can serve as a powerful starting point for user models
  • First steps in implementing a new ejector component

A new TESPy release has already been published based on the results of the hackathons. This release already includes the new ModelTemplate class and also made the OptimizationProblem class compatible with it. Further details about the release can be found in the official release notes:

A big thank you goes to Hannes Schneider from Technical University of Braunschweig for the excellent organization and for hosting the meeting. We would also like to thank all participants for the open atmosphere, their enthusiastic participation in the hackathon, and the many engaging discussions.

2025.10 first ever TESPy community meeting

TESPy has been part of the oemof organization for about eight years. While it has always been represented at the meetings, it was time for the first ever TESPy community meeting!

Last week around ten of us got together at the University of Applied Sciences in Flensburg to discuss where TESPy is headed and how we can make open source thermodynamics even better. The discussions covered a broad range of topics:

  • A review of the most recent feature additions
  • Beginner tutorials
  • Debugging with tespy version 0.9
  • Custom equations into your model
  • Implementation of new components
  • Showcases of how the software is used
  • Strategies for the operation of large scale heat pumps

During the hackathon an addition to a component was not only drafted on paper but actually implemented in the framework. And, it has already
made it to the latest release of TESPy.

It was really inspiring to meet others working with the software, exchange ideas, and see how the community is growing. Thanks to everyone who took their time to come to Flensburg to join the meeting.


Looking forward to the next one!
