Second citizens' forum on municipal heat planning
The heating plan is here - second citizens' forum in the Rheingoldhalle
On March 11, 2026, the second public forum on municipal heat planning (KWP) took place at the Rheingoldhalle in Mainz. Around 200 residents took the opportunity to review the finalized draft of Mainz’s heat plan, ask questions of experts from the trades and energy consulting sectors, and contribute to the participatory process.
Results of municipal heat planning
In addition to engaging in dialogue with Mainz residents, the evening focused on the presentation of the draft municipal heating plan for the state capital of Mainz. The plan outlines how Mainz intends to make its heating supply climate-neutral by 2040 at the latest—and ideally as early as 2035.
