Sep 2019: Dresden District Heating Project Set Up In Regulatory Sandbox

September 2019

Nearly half of the households in the city of Dresden are connected to its district heating network.

Now a project that aims to make the system more energy efficient and environmentally friendly has been set up within a so-called regulatory sandbox.

CityImpuls DD is one of 20 industrial-scale field tests of energy technologies that recently won access to a federal funding pot worth 100 million euro per year. A further 200 million euro will be made available for projects in regions of structural change. Over 90 consortia participated in the competition, representing 500 players from industry and R&D institutions.

This first round focussed on three topics:

  • Sector coupling and hydrogen technologies;
  • Large-scale energy storage in the electricity sector;
  • Energy optimized neighbourhoods.

CityImpuls DD foresees a gradual reduction in flow temperatures in Dresden’s heating network. Six solar-thermal plants, heat pumps, and a large heat storage facility will feed energy from renewable sources into the network, reducing its carbon intensity. The network’s hydraulics will be completely overhauled and a number of new technical aspects introduced.

The German federal government introduced the regulatory sandbox concept to enable new products and business models to be tested under real-life conditions but with legal flexibility in the regulatory environment. Authorities also hope to gain insight into potentially beneficial regulatory changes.
