With the introduction of the Federal Heat Planning Act (WPG), all municipalities in the country are currently obliged (Federal Government draft law, WPGE, Bundestag printed paper 20/8654) to carry out a form of municipal heat planning, depending on the size of the municipality, by 30.06.2028 at the latest. The aim of heat planning is to develop a strategy paper which, based on the current initial situation of the heat supply in the municipality, outlines a way to achieve a climate-neutral, sustainable heat supply by 2030 and 2035 to 2040 via the interim targets. Municipal heating plans are an essential part of the climate transition. With the listed options for action to reduce greenhouse gas emissions in the heat supply, they form the basis for a greenhouse gas-neutral building stock and a greenhouse gas-neutral heat supply. In order to achieve these goals, the bidders in the heating plan will develop concrete technology solution proposals in order to derive short, medium and long-term measures in a heating transition strategy.
