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
