Landsnet’s transmission system – ‘the grid’ – carries electricity from generation companies to utilities and power-intensive industries.
The grid includes more than 3,000km of transmission lines and about 70 substations and transformer stations.
Mainly overhead lines
The vast majority of our transmission lines are overhead lines, with underground lines in the minority. The largest part of the grid’s transmission infrastructure operates at a voltage between 30 and 220 kV
