The transformation of the heating supply is one of the key levers for achieving climate protection targets at municipal level. In Germany, the heating sector accounts for around 55% of final energy consumption – predominantly from fossil sources. The municipal heat transformation aims to systematically replace fossil heat generation with renewable heat sources and highly efficient networks. <\/p>\n
Municipalities are not only supply areas, but also designers: they set target grids, define expansion priorities and implement the legal framework locally. With clear transformation planning, municipalities can combine security of supply, climate protection and economic location advantages. <\/p>\n
A successful municipal heat transformation is strategically planned, legally sound and financially secure. It requires a combination of sound analysis, clear targets, realistic timetables and viable financing concepts. With these guidelines, a municipality can take a structured approach to the transition from a fossil fuel-based heat supply to a climate-neutral heating network. <\/span><\/p>\n The plan can be worked out in the following structure:<\/span><\/p>\n<\/div> Inventory (current status)<\/b>: Survey of the existing heat supply (technologies, energy sources, age of systems).
