Steady Progress Reshapes Australia’s Energy Market — July 2026 Update

Australia's electricity market kept shifting toward renewables in the second quarter of 2026, according to the latest figures from the Australian Energy Market Operator. Wind, grid-scale solar, and rooftop solar together grew 37% year on year, while coal generation fell 5% and gas fell 30% — both hitting their lowest quarterly levels since 2003. That extra renewable supply, plus a fast-growing fleet of home and grid batteries, pushed wholesale electricity prices to their lowest point since 2020. Household battery capacity rose 41% over the year, and grid-scale battery capacity more than doubled. Rooftop solar installations were also up sharply, with nearly 340 megawatts added in July alone, often paired with a home battery.

None of this has yet translated into lower bills for households — those wholesale savings haven't been passed on to customers yet. Some analysts also doubt Australia will hit its 82% renewable-energy target by 2030, pointing to delays connecting new projects to the grid and permitting holdups. Meanwhile new pressures are building: aging coal plants are breaking down more often, and a wave of planned data centers could demand as much extra electricity as one of Australia's larger states uses today.

For homeowners, the takeaway is mostly about direction rather than immediate savings: solar and battery adoption keep climbing, and coal keeps losing ground, but wholesale price drops haven't shown up on power bills yet. If you're in Australia and considering solar or a battery, it's worth checking whether your state's rebates or incentives have changed alongside this shift.
