When Cameron Botterill left home one morning, he did not expect to return to 15-metre power poles soaring above his residential street in Melbourne's inner west.
"They're absolute monstrosities," Mr Botterill said. "They're ginormous. They tower above anything else in the suburb and they look very industrial."
The new poles, which carry up to 66,000 volts of electricity — roughly 160 times the voltage previously running through his street — were installed as part of a network upgrade to power a data centre operated by NextDC in West Footscray. Another data centre is proposed for the suburb and one more for Spotswood.
Mr Botterill said he was notified in July that power would be shut off to replace the poles, but only learned the reason on the day they went up. "I asked them why they had installed this. They told me it was to run power to a data centre. That data centre is at least over a kilometre away," he said.
Professor Michael Brear, a mechanical engineering professor at the University of Melbourne, said the taller poles were required for safety and economic reasons when supplying large loads like data centres at higher voltages.
Jemena told ABC's 7.30 program: "We have heard feedback from residents and other stakeholders that our communication and engagement could have been better, and we are taking that feedback seriously." The company has since paused works to listen to community concerns. Paul Tyndale was another resident caught by surprise when Jemena crews disconnected his power in Spotswood.
The episode highlights the growing physical footprint of the AI boom as data centre demand drives rapid grid upgrades, often clashing with local communities.
