Damaged green dome
Make the safe call and report an electrical emergency immediately on 13 13 51 to keep you and your community safe.
Green domes (also known as green pillars) are mainly found in areas with underground power, in front of your house, in parks/reserves, or on roadsides. They're important as they house the electrical wiring that supplies power to your property so you can enjoy a grid-powered lifestyle.
They're tough and provide a high level of protection to the wiring inside, however it's important to know that a damaged green dome is as dangerous as a fallen powerline. If you have a cracked or broken green dome on your property or in the community, stay at least eight metres away and report it to us immediately on 13 13 51.
Green dome FAQs
You may have seen a green dome (also known as a green pillar) on your property or in your neighbourhood and wondered, what does a green dome do and why do I have one?
Green domes play an important role in delivering electricity to you – it is the point of connection between your property and the main electrical network that runs along your street.
It is the same electrical wiring that runs from power poles to the top of houses, except underground. The green dome acts as a protective housing for the electrical wires that feed a property.
They are primarily found in areas where there is an underground power supply.
Green domes can be found in areas with overhead power poles and wires, in particular public areas like parks and roadsides, or where new houses have been built in the area (as all new subdivisions must install underground power connections).
It’s easy to miss them, as they are coloured green to blend in with natural surrounds, however it is important to remember that they play an important role in supplying your property with power and, if damaged, pose the same risk as a downed powerline. If you see a damaged green dome, it is important you report it to Western Power immediately on 13 13 51.
You can also apply to relocate your green dome or convert your overhead power supply to underground.
If you’ve contacted a green dome with your vehicle it’s important you stay inside until you have sought further instruction from Western Power. Wires carrying potentially life threatening amounts of electricity may be in contact with the vehicle which may energise it.
The safest option is to stay inside the vehicle until help arrives or you’re instructed otherwise by Western Power. If it’s unsafe to stay in your vehicle, jump well clear keeping both feet together. Don’t touch the vehicle and ground at the same time then shuffle away keeping both feet together. Check out this handy video about what to do if your vehicle is in contact with live electricity.
Human interference is the main cause of damage to green domes.
This includes vehicles driving into or over the green dome, construction/building activity, landscaping activity and people playing or jumping on the green dome.
Grass or bushfires also lead to green dome damage.
If you or somebody in your presence damages a green dome, report it to Western Power immediately on 13 13 51.
Remember, a damaged green domes is as dangerous as a downed powerline.
Not all houses in underground power areas have their own green dome. Some green domes can service multiple properties, so you may see one for every second or third property along the street.
