Power bill shock: households face energy cost increases

May 26, 2025 11:13 | News

Power bill increases of upwards of nine per cent have been locked in for some Australian households as energy regulators make a final call on safety net prices.

Caps on what retailers can charge households and businesses in NSW, South Australia, southeast Queensland and Victoria are designed to protect the hundreds of thousands of customers who tend to set-and-forget their power plans. 

Roughly nine per cent of households and 18 per cent of small businesses are on default market offers.

NSW customers on standing offers face the steepest price growth of somewhere between 8.3 per cent to 9.7 per cent, depending on their network area.

Some users in the state could be slugged with an $280 extra annually from July 1. 

Regulators update default market offers to reflect the cost retailers are paying generators for electricity and to have it transported through poles and wires.

Australian Energy Regulator chair Clare Savage said NSW was experiencing bigger increases in wholesale costs and transmission than other states.

“In NSW we’ve seen some unexpected outages of coal-fired power stations, which can drive up that wholesale cost,” Ms Savage told ABC Radio on Monday.

She also flagged boosted investment in networks to make them more resilient to cyber attack and climate risks, such as the floods devastating parts of NSW. 

Other states covered by the AER’s remit are in line for more modest increases, though Ms Savage said wholesale and network costs rose in most jurisdictions.

Residential customers on default plans in southeast Queensland can expect hikes of anywhere between 0.5 per cent and 3.7 per cent, while people in South Australia face rises of 2.3 per cent to 3.2 per cent.

Victorian households can expect a modest one per cent average bump, according to the Essential Services Commission, with some distribution zones actually in line for small drops in prices.

Households and businesses nervous about energy bill hikes have been urged to shop around, with 80 per cent of customers likely to save money by chasing better deals. 

Energy Minister Chris Bowen acknowledged power prices were putting pressure on households and businesses, pointing to extended bill relief in the last budget.

“It’s clear energy bills for Australians remain too high, and we’re providing help for people doing it tough as we deliver longer term reform.”

He also urged people to shop around, with savings of up to 27 per cent possible by switching to a competitive market plan.

Energy Consumers Australia chief executive officer Brendan French said the safety net system was not working effectively if priced as much as 27 per cent above market offers. 

“The sector should be focused on reducing costs at all stages of the supply chain, and making networks as efficient as possible, otherwise consumers risk losing the benefits of the energy transition,” Dr French said.
