Transmission: electricity is transported from power generating stations (fossil fuels, renewable or other sustainable forms) through High Voltage (HV) transmission networks. The HV is then reduced to lower voltages at substations and distributed to a range of energy users.

Distribution: electricity is distributed to industry, business and homes via ‘bulk supply’ substations and electricity networks.

Rail: electricity is distributed to transport people and goods by various types of rail traction vehicles such as trains, trams and other light rail systems.
