Heat supply in Biestow: interruption on June 26th! This is how affected you are!
There is a short-term but necessary interruption to the heat supply in Rostock, which will affect some customers in Biestow. On Thursday, June 26, 2025, the heat supply will be interrupted between 6:00 a.m. and 5:00 p.m. so that Stadtwerke Rostock AG can carry out essential work on a district heating pipeline. This procedure is crucial for the safe operation of the entire district heating network, reports the Rostock city administration.
The reason for the interruption is the relocation of a line on Ernst-Häckel-Straße. This measure requires the system to be separated, which means that the affected households will have to do without domestic hot water and heat for heating during this time. In order to minimize such disruption, Stadtwerke Rostock carries out this work outside the heating season, if possible. There will be an overview of the affected roads and further information on their website.
District heating in Rostock and climate change
The importance of district heating in Rostock is constantly growing, especially in view of the challenges of climate change. According to the [AGFW](https://www.agfw.de/energiewirtschaft-recht-politik/energiewende-politik/ueberblick-fakten-und- Answeren-zu-fernwaerme), the city's winding network is not only used to supply heat, but also to integrate various technologies to generate climate-neutral heat. There are around 3,800 district heating networks in operation in Germany, which are also supported by renewable energies.
A modern heating plan, which was confirmed by the Rostock citizens on June 22, 2022, is intended to ensure a climate-neutral heat supply by 2035. This strategy is part of municipal heat planning and envisages using further innovative technologies such as power-to-heat systems and heat pumps to actively promote the energy transition. These measures will reduce dependence on fossil fuels and increase the share of climate-neutral energy in the heating sector.
Investments and future projects
Stadtwerke Rostock has already invested in a new heat storage facility, which has been in operation since 2023 and holds 45 million liters of hot water. This means that district heating customers can be supplied independently on a weekend. A power-to-heat system is also being planned to further improve the sustainability of the district heating supply. This is particularly important in order to use excess electricity from renewable energies and thus make a significant contribution to the energy transition, according to the BDEW.
The heat plan considers various measures and strategies to achieve the set climate goals. Far-reaching steps should be taken by 2035 to make the district heating supply in Rostock safe, affordable and climate-neutral. A good hand in dealing with existing resources is required in order to take into account both the needs of the population and the ecological challenges.
It is important for the citizens of Rostock to be aware of such developments in order to better understand and adapt to future changes in heat supply.
