Municipal heat planning
Goals
Municipal heat planning should make a significant contribution to a cost-efficient, sustainable, economical, affordable, resilient and greenhouse gas-neutral heat supply. The Chemnitz heating plan will provide the specialist departments involved and building owners with guidance on how the climate protection target of a climate-neutral heat supply by 2040 (municipal target), or by 2045 at the latest, can be achieved. The respective plan is also an important tool for sustainable urban development.
Timetable
The municipal heat planning officially started in Chemnitz with the kick-off on 20 June 2024. The city of Chemnitz must have completed its heat plan by 30 June 2026, as this is the legal deadline for the preparation of the law on heat planning and the decarbonisation of the heating network (WPG).
As part of work package 1), the inventory analysis, the extensive data basis for the plan was compiled and transferred to standardised geoinformation systems. The energy supplier eins energie in sachsen GmbH & Co. KG and the grid operator inetz GmbH were primarily involved in the inventory analysis. The subsequent potential analysis shows the expected development of heat demand in Chemnitz as well as the potential for reducing greenhouse gas emissions. Strategies and measures are derived from the analyses that are intended to contribute to Chemnitz's climate neutrality. These will be presented to the public and, in particular, to the public authorities. Following the extensive involvement of stakeholders, the overall concept will be presented, which is expected to be submitted to the City Council towards the end of 2025 with the involvement of the relevant committees.
Municipal heat planning will be continued and revised every five years.

First information event successfully held
First information event
On 8 May 2025, the first information event on municipal heating planning took place at the "Am Hartmannplatz" secondary school. The event, which was aimed at the general public, was attended by around 80 participants.
During the event, the new planning task of municipal heat planning and the current status of the inventory and potential analysis were presented. Before and after the event, there was the opportunity to ask questions to the experts present from the City of Chemnitz, the Saxony Consumer Advice Centre, Klimabündnis Chemnitz, eins energie in Sachsen Gmbh & Co KG, inetz GmbH, an expert on the Building Energy Act from the Institute for Technical Building Services Dresden and the Saxon Energy Agency (SAENA).
The official part of the lecture with presentation of the interim results by the commissioned planners began at 5 pm. Following the presentation, the opportunity was taken to address questions to the experts present and to engage in dialogue.
Kickoff
Municipal heating planning is another piece of the puzzle towards greenhouse gas neutrality in the city of Chemnitz. It is intended to make a significant contribution to a cost-efficient, sustainable, economical, affordable, resilient and greenhouse gas-neutral heat supply. Measures are to be developed with which the city area can be supplied with climate-friendly heat.
The kick-off for Chemnitz's heat planning took place on 20 June 2024 at the eins conference centre on Straße der Nationen. Key parties involved in the planning came together for an initial exchange of information about the next steps. The project organisers, GEF Ingenieur AG and the Brandenburg University of Technology Cottbus-Senftenberg, introduced themselves. Dr Stephan Richter, CEO of GEF Ingenieur AG, says: "We are delighted to be accompanying the city of Chemnitz on the way to its municipal heating plan and to be working together to make decisive progress with the local heating transition."
Public information events are also planned as part of the project in order to involve the people of Chemnitz in the process. "Transparent and target group-oriented heat planning is necessary for the further decarbonisation of Chemnitz's heat supply. It is an essential pillar for greenhouse gas neutrality in 2040," says the head of the City of Chemnitz's environmental department, Ms Carina Kühnel. The project benefits from 90 per cent federal funding as well as from existing heat plans in Germany.
The heating plan serves the city of Chemnitz as an informal planning instrument that outlines the long-term development of the heating sector. This allows future measures to be harmonised. The heating plan shows how the heat supply should develop technically, spatially and over time. However, this does not result in any legal obligation. Building owners are still free to choose their heating technology.
FAQ
Chemnitz is currently (as of 2022) mainly heated with fossil fuels. Chemnitz has an annual heating requirement of 2,315 gigawatt hours. The following scales result for the energy sources in total heat consumption.
The abbreviation "WP" used in the diagram stands for the heat pump.
Natural gas and district heating dominate as energy sources in Chemnitz.
Heat consumption is stated in megawatt hours.
The residential sector consumes by far the most heat.
Heat consumption is stated in megawatt hours.
In the balance year 2022, 589,153 tonnes ofCO2 equivalent were emitted in Chemnitz due to heat consumption.
The annual emissions are stated in tonnesof CO2 equivalent.
For Chemnitz, municipal heating planning provides a valid planning basis for decarbonising the heating sector. It therefore makes a significant contribution to the city's 2040 climate neutrality target and is another important basis for sustainable urban planning and development.
The heating plan provides building owners and citizens with an orientation on the possible future of heat supply.
Companies from the housing industry, the energy supplier eins energie in sachsen GmbH & Co. KG, the grid operator inetz GmbH as well as the project organisers GEF Ingeneur AG and the Brandenburg University of Technology Cottbus-Senftenberg are mainly involved in drawing up the heating plan.
