Taller power poles expose tensions over Melbourne data-centre expansion

Residents in Melbourne’s inner west have protested against 15-metre electricity poles installed as part of a network upgrade associated with growing demand from data centres. Cameron Botterill, whose home is near the new infrastructure, said the poles appeared within a day and were more than twice the height of the seven-metre wooden poles they replaced. The new poles can carry up to 66,000 volts, according to ABC News.

Jemena said the upgrade was intended to support Melbourne’s growing energy needs. Michael Brear, a mechanical engineering professor at the University of Melbourne, said taller poles were mainly required for safety when supplying a large electrical load at a higher voltage. The dispute has also highlighted concerns about communication.

Jemena acknowledged that its engagement with residents could have been better and said it had paused works to listen to community concerns. Some Yarraville residents blocked equipment with cars and bins to prevent installation work. In Spotswood, resident Paul Tyndale said his family learned about a proposed data centre from a worker disconnecting their power.

Jemena said extending the existing overhead network was the most efficient and practical option, while underground powerlines would be more expensive and complex. Data-centre operators are required under the National Electricity Rules to pay connection and associated augmentation costs. Victoria’s government announced regulations banning data centres in residential areas, requiring a 150-metre buffer from homes and mandating renewable power.

Some residents say the changes came too late.
