Stadtwerke Rosenheim

Competence through tradition & Innovation since 1939

The municipal utility Rosenheim is the municipal utility of the city of Rosenheim. About 450 employees supply private and business customers with water, electricity, gas and heat. Likewise the public utilities take care of waste disposal and offer leisure activities in the Rosenheim baths. Through the subsidiary komro GmbH, the Rosenheimers also receive modern solutions for telephony, broadband Internet and cable television.

Pioneering - pioneer for the energy sector

In the context of the energy turnaround, Stadtwerke Rosenheim is one of the pioneers for a regional, ecological and sustainable energy supply. The goal: economically sensible and effective climate protection. For a high degree of independence in energy generation and a CO2-neutral supply of electricity and heat. To achieve this, Stadtwerke Rosenheim continuously invests in efficient and modern technologies. For years, they have been working consistently on the implementation of their ambitious climate protection goals, which can be read in their well-founded energy concept. This documents their actions for energy generation in Rosenheim. Environmentally friendly technology, affordable prices for consumers, continuous optimization of technical facilities and innovative strength are the challenges here. The competence and commitment are reflected in the results already achieved in the past. It is also the basis for achieving the goals set for today and tomorrow. Stadtwerke Rosenheim is working on a good energy future.

The focus of the energy concept is on cogeneration, i.e. the integrated production of heat and electricity. In addition to hydropower and residual waste incineration, the municipal utilities will in future also rely on a domestic and renewable energy source: wood. For this purpose, Stadtwerke Rosenheim has developed its own wood gasification process, which, in contrast to conventional wood combustion, is much less polluting and more energy-efficient and saves twice as much CO2 from fossil fuels.

Excerpt from the energy projects:

• Environmentally friendly refrigeration supply - Awarded the Bavarian Energy Prize 2020 Instead of using, as is often the case, electrically driven compression refrigeration machines with relatively high power requirements and F-gases as refrigerants, this project predominantly uses thermally driven absorption refrigeration machines that operate with the natural refrigerant water. Waste heat, which is available in summer from the waste-to-energy plant also operated by Stadtwerke Rosenheim, is used as the drive energy. This makes better use of existing heat. The integration of electricity, heat, cooling and heat storage is a prime example of sector coupling and allows renewable energy from wind and solar power to be used and supplemented very flexibly, depending on the situation.
• Generating wood gas from waste wood Converting wood into combustible, climate-neutral wood gas at 1,000 °C - SWRO has been relying on this in small plants for years. Thanks to a new research project, this technology can now be further developed on a large scale: SWRO also wants to generate bioenergy from waste wood that can be used in combined heat and power (CHP) plants to provide electricity and heat. A further step towards achieving climate targets.
• iKWK - Threefold Climate Friendly In 2019, Stadtwerke Rosenheim has been awarded a total of three iKWK projects by the Federal Network Agency. A total of 19 million euros will thus be invested over the next few years. The iKWK plants will go into operation in 2020, 2022 and 2023 and will generate around 7 MW of innovative renewable heat from the final expansion stage. The approved plants are an ideal fit with our energy concept, the existing power plant fleet and the well-developed district heating network. And through the district heating with the help of renewable energies, this will now be even "greener"'!
