Structure of the electricity grid

The Danish electricity grid is divided into different voltage levels:

  1. The overall electricity transmission grid at the highest voltage level 400 kilovolt (kV). This grid connects the large-scale power stations in Denmark and abroad to each other and to the electricity grid at lower voltage level. This electricity grid is owned by Energinet.dk.
  2. The regional electricity transmission grid on 132 kV east of the Great Belt and 150 kV west of the Great Belt. This electricity grid connects the overall transmission grid to the distribution grid. It is normally also at this voltage level the large-scale offshore wind farms are connected. However, Anholt Offshore Wind Farm is connected to the electricity grid with a 220 kV cable. Energinet.dk owns this grid.
  3. The distribution grid transports the power the last part of the way to the households and companies. This grid is owned by local grid companies.

Between the different voltage levels are substations, which increases or decreases the electric voltage.

The Danish transmission system is linked to the transmission systems in Germany, Sweden and Norway.
