Overview: Vienna is certainly one of Europe’s most impressive cities. From its cafes to the palaces, passing by its museums, the city captures the eyes, ears, and hearts of those visiting it. Vienna’s grandeur has survived through the centuries and continues to this day.

Current DH system: Equally grand is its district heating systems, one of Europe’s largest, supplying heat to more than 370.000 residences and 6.800 tertiary customers. The heat sources are many – heat incineration, gas boilers, biomass, heat pumps, waste heat, and many more.

What work will ENABLE DHC do: The project will further push for the decarbonisation of the grid, by investigating the implementations of geothermal, large-scale heat pumps, and other sources of waste heat. The phase out of fossil fuels will be complemented with works to test the system’s robustness against energy prices variations, changes in demand, and evolving regulatory frameworks.
