Green domes - Different size, same risk

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.

We receive around 3,000 calls/year regarding damaged green domes. Around 2,500 need replacement or repair by our crews.

The most common cause of damaged green domes are related to third party incidents – driving straight into them

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.

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 dome 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.

Where it's part of undergrounding work that we deliver, green domes are installed by Western Power crews or our approved contractors. We have specific requirements as to how the green domes must be installed to ensure they operate efficiently and safely.

Private electrical contractors also install green domes when they are doing work for private customers, such as residents, builders or land developers. Western Power does not own all the green domes / pillars in the community. Some are privately owned and maintained as part of an installation, or by utilities such as the Water Corporation.
