 | | You are here: Our Network > Your electricity supply
EnergyAustralia is not only a national retailer of electricity and gas, but we also distribute electricity to customers in the Sydney, Central Coast and Hunter regions of NSW, along a vast network of substations, poles and wires.
The EnergyAustralia network distributes more than 25,000 GWh of electricity annually, to 1.4 million customers through:
- More than 1000km of above ground 132kV high voltage cable
- Almost 500km of underground 132kV high voltage cable
- More than 400km of 66,000 Volt (66kV) cables.
- More than 2200km of 33,000 Volt (33kV) cables.
Our electricity supply is taken from the NSW transmission network at either 132,000 or 66,000 volts and reduced to 33,000, 22,000 or 11,000 volts through a network of transmission and zone substations. Street-based distribution substations further reduce supply to levels that meet our customers’ home or business requirements.

|  Characteristics of supply
It is inevitable that from time to time you may experience a temporary power fluctuation or interruption. Reasons can include planned or emergency maintenance or damage to the network.

| Electric and Magnetic Fields - EMF
Electric and magnetic fields (EMF) are part of the natural environment and are present in the earth’s core and the atmosphere. These fields are also produced wherever electricity or electrical equipment is in use.
When turned on (including ‘standby’ modes) your computer, television, hair dryer, electric blanket and clock radio all produce EMF, as does the photocopier at work, and any other electrical appliances that electric current is flowing through. The electrical wiring in any home or building also produces EMF.
Electrical energy involves ‘voltage’, which is the pressure behind the flow of electricity that produces an electric field, and ‘current’, which is the quantity of electricity flowing that produces a magnetic field.
At extremely low frequencies such as power frequencies, electric and magnetic fields do not normally radiate from their source. They merely exist in the space surrounding their source, and the strengths of the fields decrease rapidly with distance from their source.
On the other hand, at much higher frequencies such as radio frequencies, energy is radiated away from the source and can be detected at great distance. Other familiar examples of radiating fields are television signals, microwaves and sunlight. It is for this reason that power frequency EMFs are described as ‘fields’ and not ‘radiation’.
