The centre lines of route corridors for operational High Voltage Overhead Lines are shown in red against a small scale map background. These operate at up to 400 000 volts.
The centre lines of route corridors for the operational High Voltage Underground Cables are shown in green against a small scale map background. These operate at up to 400 000 volts.
If there is no map background then we do not have such lines and cables in the area.
Please note that overhead lines or underground cables that are under construction or that have been recently constructed or diverted may not be shown.
