On behalf of Stadtwerke Bernburg large-scale solar heating specialist Arcon-Sunmark has begun construction of the second largest solar district heating system to date in Germany. Construction is expected to be completed in November, and the system will have an annual yield of 2,300 MWh with a peak effect of 5.6 MW. 632 collectors with a total aperture area of 7,938 m2 harvest energy from the sun which is transformed into district heating.

     “Stadtwerke Bernburg is renowned for being one of the frontrunners in reducing CO2-emissions
     via investing in renewable energy. We are proud to have been chosen as partner for this
     project. Large-scale solar heating is one of the most effective and cost-efficient of all the
     renewable energy technologies, and the people of Bernburg will benefit from this investment 
     for many years to come,” says Thomas Karst, CEO, Arcon-Sunmark.

Berlin project raised awareness
The project in Bernburg is Arcon-Sunmark’s third so far in Germany this year. In May construction of a 3.3 MW system in Halle began and in July construction of the biggest large-scale solar district heating system in Germany was initiated in Ludwigsburg. The latter has a peak capacity of 9.6 MW. Several other projects in Germany and Central Europe are currently being outlined, and it is expected that new projects will be confirmed very soon. In May 2018 a pioneering large-scale district heating project in Köpenick, Berlin was handed over to Vattenfall. The project has attracted a lot attention from energy suppliers and political decision makers from all over Germany. 

     “The system in Köpenick has been a game changer for us in the German market. In Germany
     there has been a general interest for large-scale solar heating for many years, but now
     interest very often is replaced by concrete dialogue and outlining of projects,”
     says Thomas Karst.
