Transmission and distribution

The transport of secondary energy is divided into "Transmission" and "Distribution". The transport can be compared to the road system where there is someone who manages motorways and the overall road system, and others that control the smaller more local roads. The losses are calculated as the difference between the energy transmitted into the transport system and the energy taken out at the other end.

Transport of secondary energy

The transmission

  • Transmission of Electricity is performed in the high voltage grid where the voltage is above 100 kV. In Denmark, Energinet.dk is responsible for the high voltage grid
  • Transmission of heat in larger pipes. In the Copenhagen area, for example. CTR and VEKS are responsible for transmission. In the Triangle area Tvis is responsible

The distribution

  • Distribution of electricity is done through local consumer owned distribution companies
  • Distribution of district heating is done via the district heating companies
  • Distribution of oil products is done via the oil companies and other private actors
