workshop: cross-sectoral planning of energy systems

Sector coupling – but how?
A workshop on the topic of “Cross-sector planning of energy systems – the basis for a sustainable energy supply” took place in Dresden on September 26, 2025, with experts from energy suppliers, municipalities, and various scientific institutions. The lively discussion demonstrates that we have addressed a highly topical issue with the workshop. The focus in the future will be on data acquisition and data interpretation for the reliable design of energy systems. AI methods in particular will make a significant contribution, which will also have a strong impact on the research landscape. It is foreseeable that digitalization and traditional energy technology will merge, which will also create new career opportunities for engineers.
Many thanks to everyone for the excellent preparation and successful execution of the event.

Evaluation 2nd ZellSys – citizen survey

As part of the ZellSys project, a second citizen survey was conducted from 02.11.-20.12.2024.

The aim of the ZellSys project is to develop a feasibility study for the transformation to a cellular energy system for the town of Wittichenau, with the clear involvement of citizens.

The aim of this survey is to compare our assumptions about future scenarios with current experiences in your region. A central concern is to compare the considerations regarding refurbishment and the development of e-mobility. Other central topics of the survey were the provision of information (type (newspaper, internet, etc.), contact points for subsidies), wishes and readiness for municipal heat planning.
At the end of the period, a total of almost 259 complete responses had been received.

Further development of possible future scenarios will be carried out using the information from the citizen survey. In addition, the local suggestions from the comments field will be taken into account in further project development.

We would like to take this opportunity to thank you for your active participation in the survey and look forward to continuing to work together on the ZellSys project for the joint, sustainable and successful further development of the town of Wittichenau.
