International Energy Demands Drive Brisbane Business Costs Higher This Month

Brisbane companies paid an average 18 per cent more for electricity in the June quarter than a year earlier, driven by global demand for data centres that power artificial intelligence systems.

The rise follows reports that data centres now rank among the fastest-growing electricity users worldwide, with new facilities planned across Asia and the United States. Brisbane businesses cannot avoid the price signal because the city draws power from the same eastern Australian grid that supplies those export-oriented projects. At the same time the Telstra network outage on 9 July cut Triple Zero calls and mobile services for hours, reminding local operators how fragile digital links have become when global supply chains for software and hardware face simultaneous strain.

Brisbane CBD and Fortitude Valley feel the pinch

Tenants along Queen Street Mall reported lost sales after EFTPOS terminals failed during the outage. Further north in Fortitude Valley, co-working spaces used by software developers and fintech start-ups stayed offline for most of the morning, forcing staff to relocate to cafes with backup generators. The Brisbane City Council’s own smart-city sensors along Adelaide Street also dropped offline, delaying real-time traffic data that logistics firms rely on to schedule port deliveries at the nearby river wharves.

Energy consultants tracking wholesale prices recorded a spike to $312 per megawatt hour on 8 July, the highest reading since the February heatwave. That figure sits well above the $187 average recorded in the same week of 2025. Several property groups that manage office towers in the CBD have begun passing on a new network surcharge of 2.4 cents per kilowatt hour to tenants from 1 August.

Businesses can reduce exposure by locking in 12-month fixed-rate contracts before the next quarterly reset and by shifting non-essential computing loads to off-peak hours. Property managers at 111 Eagle Street have already installed sub-meters on each floor so tenants can track usage and claim rebates under the council’s small-business efficiency grant that opened applications on 1 July.
