Structure of the electricity transmission system
The electricity transmission and distribution systems connect power generation units in Denmark and abroad and consumption sites.

The transmission grid (‘electricity motorways’) connects generation nodes with electricity consumer nodes.

The transmission system consists of 400 kV installations.

Energinet.dk owns the 400 kV and 150/132 kV installations and the international connections.

The Danish transmission system is interconnected to the transmission systems of Germany, Sweden and Norway. 

The substations are remote-controlled from the control centre in Erritsø via the fibre-optic grid.

Distribution grids
The distribution grids are owned and operated by the local grid companies, which transmit the electricity to the individual consumers.
