Wien Energie will be developing the city’s first geothermal heating system in Aspern with a planned 20 MW capacity. The planned geothermal heating plant will have an output of 20 MW enough to supply the heating needs of 20,000 households. If all steps go according to plan, pre-drilling work for the project will begin by 2023 with a target commissioning by 2026. One-tenth of the EUR 80-million investment that will go toward the project will be contributed by the federal government.
If the project is successful, there are plans to have up to four deep geothermal systems in Donaustadt and Simmering. Expansion plans are to be continue beyond 2030 with a target for the city to generate heat entirely from climate-neutral sources by 2040.
