Limit.
“It’s an absolute plus for us,” said Sebastian Schremp, Lord Mayor of Renstetten, pleased about the successful connection. “District Heating As a low-emission thermal energy, we are taking another major step towards the energy transition.” In doing so, they aim to make district heating more climate-friendly. Your CO2 saving potential is much greater than with conventional heat energy like heating oil or natural gas.
“The expansion of district heating is the biggest climate protection project in our city”
By using waste heat from the Upper Rhine Mineral Refinery (Miro) alone, CO2 emissions are reduced by more than 100,000 tonnes each year. “The expansion of district heating is the largest climate protection project in our city,” said Gabriel Luczak-Schwarz, the first mayor of Karlsruhe and chairman of the supervisory board of Stadtwerke Karlsruhe, in a press release.

3.5 years of construction – seven million euros in cost
In mid-2018 and after nearly three and a half years of construction work by municipal utilities and their network service, a main line of more than four kilometers with a connected load of 11 MW was constructed.
“It is designed in such a way that we can supply about 1,200 residential units with heat,” Dr. Olaf Heil, technical director of the Stadtwerke Karlsruhe. “We’ve already got applications with a connected load of 6.5 MW.”
“The construction of the main line from the border to the ‘New Mitte’, including the laying of the branch’s distribution lines, required an investment of seven million euros,” said Michael Homann, CEO of Stadtwerke Karlsruhe, reported in the report. “A good and above all, sustainable investment in the future.”
