“Municipal heat planning is an important milestone for our city’s future energy supply. I would like to particularly highlight the close and constructive collaboration between the city administration and ESWE Versorgung AG,” says Mayor Gert-Uwe Mende. “Together, we have developed a practical and implementation-oriented plan that takes Wiesbaden’s unique characteristics into account and serves as an important foundation for the coming years.”

Mayor and Head of the Environment Department Christiane Hinninge adds: “The municipal heat plan is a key component in ensuring that Wiesbaden and our heat supply can become climate-neutral by 2045. The heating plan serves as a guide and decision-making framework for the administration, politicians, the business community, and the public. It outlines, for each urban area, which types of heat supply are suitable for the future and can be technically implemented.” 

Prior to this, the Municipal Heat Plan was presented to and discussed by the local advisory councils. This allowed the results to be presented and contextualized at the neighborhood level at an early stage.

The state capital of Wiesbaden developed the Municipal Heat Plan in collaboration with ESWE Versorgung AG and with the support of external consulting firms. It is based on the requirements of the federal Heat Planning Act as well as state regulations in Hesse.

The heating plan examines the existing heat supply and analyzes the potential of renewable energy sources and usable waste heat. Based on this, a target scenario for heat supply through the year 2045 was developed. The analysis considered, among other things, district heating, heat pumps, industrial waste heat, river water heat, thermal water, geothermal energy, and other renewable heat sources.

The goal is a significant expansion of the district heating supply—particularly in central areas of the city. In neighborhoods where district heating is not economically viable, heat pumps can play a key role. The goal is a significant reduction in the use of fossil fuels and in greenhouse gas emissions.

Municipal heat planning is a strategic planning tool. It has no direct legal effect on individual properties or heating systems, but serves as a guide for citizens, businesses, energy suppliers, policymakers, and public administrators.

The heating plan is published after submission to the state and is regularly updated. Further information is available at wiesbaden.de (search term: “Municipal Heating Plan”). The Environmental Office answers questions at waermewendewiesbadende
