This ABC News Daily episode explains why Australian power bills are expected to fall even as the Iran war raises broader geopolitical tension. The key message is that batteries, more renewable generation, subdued domestic gas prices, and regulatory price resets are outweighing the kind of shock that followed Russia’s invasion of Ukraine.

The core thesis is straightforward: Australian electricity bills are now set to ease because the power system has changed materially since the 2022 energy shock. Energy reporter Dan Mercer argues that the combination of rapid battery deployment, rising renewable penetration, and a more restrained domestic gas market means Australia is not experiencing the same price surge that followed Russia’s invasion of Ukraine. He repeatedly contrasts the current situation with 2022, when wholesale electricity prices on the East Coast jumped from under $100/MWh to more than $700/MWh and household bills rose sharply. Mercer’s explanation centers on batteries. He says Australia has moved from having essentially no large-scale batteries in major grids four years ago to having substantial capacity, especially in Western Australia, where batteries can meet about 40% of peak demand. …
Tactically, Australian power bills should ease into the July pricing reset, but consumers need to switch plans or they may miss the benefit. The near-term risk is retailer offsets or state-specific differences, with South Australia already showing a slightly higher regulated price.
Over the next several months, the base case is lower or flatter electricity prices as batteries continue to shave evening peaks and renewables supply more of the load. That view weakens if coal exits, network charges, or demand growth outpace new firm capacity.
Structurally, Australia looks to be moving into a more electrified grid where storage and renewables matter more than imported fuel costs. The lasting question is not whether power can get cheaper in spots, but whether the transition’s network and reliability costs overwhelm those gains.
Australian power bills are expected to fall from July after several years of steep increases.
The host introduces the segment by saying bills are about to fall, and Mercer gives regulator-based cuts by state.
The 2022 spike in electricity costs was largely driven by Russia’s invasion of Ukraine and the associated surge in global gas and coal prices.
Mercer directly links the earlier bill shock to the Ukraine war and worldwide energy price spikes.
Large-scale batteries are a major reason Australian electricity prices are not spiking as hard as they did in 2022.
Mercer says batteries now flatten peaks, soak up daytime solar, and reduce the need for gas at peak times.
How is it that our power bills are about to fall, when it feels impossible for the cost of anything to come down?
The drop is driven by the Australian Energy Regulator cutting default market offers — ceiling prices that serve as reference points for retailers. In Southeast Queensland rates will fall up to 10.7%, in NSW up to 5%, with the exception of South Australia where prices will rise slightly by 1.4%. Small businesses in NSW will see up to a 20.9% drop. The decline is relative to the extraordinary highs after Russia's invasion of Ukraine, and is partly due to batteries and renewables flattening price peaks.
Why isn't the Iran war having the same impact on energy prices as the Ukraine war did?
Gas prices in Australia have stayed subdued this time because we're using less gas to produce power, and arguably a bigger reason is the threat of a domestic gas reservation policy hanging over producers. Exporters are playing nicely in the local market to avoid aggravating the situation, unlike last time when that threat wasn't a factor.
How much will power bills actually drop by?
The Australian Energy Regulator cut default market offers — ceiling prices used as reference points. In Southeast Queensland rates fall up to 10.7%, in NSW up to 5%, while South Australia will see a small rise of 1.4%. Small businesses get larger breaks, with NSW small business rates falling 20.9%. For a household this means maybe a couple of hundred dollars a year off.
