Electricity prices in Australia are expected to fall broadly from July, with some households and small businesses seeing reductions of up to 10%.
According to the 2026–2027 “Default Market Offer” released by the Australian Energy Regulator (AER), electricity bills for households in New South Wales and south-east Queensland are expected to drop by 3.4% to 10.7% compared with last year. Some consumers could save up to A$155 annually. Victoria will also see price reductions, with average household bills falling by about 5% and business bills by about 6%. Around 987,000 households and 139,000 businesses currently rely on the Default Market Offer as a safety pricing mechanism.
Regulators said the large-scale integration of battery storage into the grid, combined with continued growth in solar and wind generation, has helped reduce price volatility during peak demand periods. Batteries are increasingly replacing more expensive gas and hydro power at night, smoothing overall price curves and lowering forward electricity contract prices. This has helped stabilise electricity costs even amid global energy market uncertainty.
The new pricing scheme also includes a “solar sharer” option, allowing customers with smart meters to access up to three hours of free electricity during midday. Regulators are encouraging households to shift usage—such as laundry, air conditioning, and electric vehicle charging—to daytime hours to reduce bills further.
Recent industry data shows Australia has become one of the world’s top three large-scale battery markets. Renewable energy supplied 43% of the country’s electricity in 2025, surpassing 50% in the final quarter of the year for the first time. However, the report also warns that new investment in wind and solar has slowed significantly, with the next five years likely to face structural bottlenecks.
Commentary:
The fall in electricity prices is clearly positive for households and reflects a rapidly changing energy system. As renewable energy and battery storage expand, they are increasingly stabilising the grid and replacing coal-heavy generation, leading to a more efficient and less volatile power market.
However, the slowdown in new wind and solar investment raises concerns. If infrastructure development and capital support fail to keep pace, the current price benefits driven by batteries and renewables may not be sustained in the long term, and the energy transition could face significant challenges.
