Green heat for Mannheim and the region
Since February 2020, our waste incineration plant on Friesenheimer Insel in Mannheim has been connected to the regional district heating grid. This means that up to 30 percent of the annual heating requirements in Mannheim and the region now come from renewable energies.
The MVV district heating grid has a length of 567 kilometres and supplies not only Mannheim, but also Heidelberg, Schwetzingen, Brühl, Ketsch and Speyer. In Mannheim alone, more than 60 percent of households, or 120,000 households, use environmentally-friendly district heating.
In Mannheim, district heating already saves around 300,000 tonnes of CO2 per year compared with other conventional heating systems. The environmentally-friendly green heat boosts this positive energy balance even further: it enables up to 100,000 further tonnes of CO2 to be saved each year. The green heat is thus one of the largest CO2 reduction projects in Mannheim.
With our green heat, we will be able to guarantee a reliable supply of heat even after the phasing out of coal. District heating is and will thus remain an indispensable component of our sustainable and future-oriented heating concept.
The use of heat from waste incineration means that the primary energy factor of our district heating amounts to only 0.42. This makes it easier for house owners to meet the legal climate protection requirements.
We have been operating our waste incineration plant on Friesenheimer Insel in Mannheim using highly efficient cogeneration since 1965. We use the resultant heat to supply steam to neighbouring industry and feed it into the district heating grid in Mannheim and the region.
