The following main findings are summarized as follows:

  • Various technical examples on how surplus heat can be integrated in district heating systems are
    provided from different partner cities, e.g. surplus heat from various types of production industry,
    computer centers, grocery stores, and hospitals (cooling).
  • Surplus heat supply to DH network is feasible if the industry is located near the DH network and
    meet required heat parameters.
  • Challenges regarding current taxes and levies structure often needs to be addressed if utilitsation
    of surplus heat is to be an economical viable business.
