Australian households could see further relief on their energy bills following a significant drop in wholesale electricity prices across the National Electricity Market (NEM) in the second quarter of 2026. The Australian Energy Market Operator (AEMO), in its latest Quarterly Energy Dynamics (QED) report, released on 2 July 2026, revealed that average wholesale electricity prices fell by an estimated 22% across the NEM for the April-June period compared to the first quarter of the year.
This substantial reduction is primarily attributed to a surge in renewable energy generation, particularly solar and wind, combined with softening domestic gas prices and milder weather conditions reducing overall demand. While the direct impact on household retail bills is subject to a time lag due to retailer hedging strategies and regulatory cycles, a sustained period of lower wholesale costs typically translates to downward pressure on future Default Market Offers (DMOs) and standing offers.
Regional Price Performance: A Detailed Breakdown
The AEMO QED report highlighted varying but universally positive trends across the NEM states:
| Region | Q1 2026 Avg. Wholesale Price (AUD/MWh) | Q2 2026 Avg. Wholesale Price (AUD/MWh) | Percentage Drop |
|---|---|---|---|
| New South Wales | $85.50 | $68.40 | 20% |
| Victoria | $92.00 | $69.00 | 25% |
| Queensland | $88.00 | $72.16 | 18% |
| South Australia | $95.00 | $68.40 | 28% |
| Tasmania | $78.00 | $66.30 | 15% |
South Australia experienced the most significant decline, with wholesale prices dropping by 28% to an average of $68.40/MWh. This was largely driven by its high penetration of solar and wind energy. Victoria also saw a substantial 25% reduction, reflecting increased output from its growing renewable energy zones.
“The second quarter of 2026 demonstrates the increasing influence of Australia’s rapidly expanding renewable energy fleet on market dynamics. We’re seeing sustained periods where high renewable output is effectively pushing wholesale prices down, delivering tangible benefits to the energy system,” stated AEMO CEO, Daniel Westerman, in a media briefing accompanying the report’s release.
Renewable Surge and Gas Price Relief
The primary driver behind these price reductions is the continued growth and strong performance of renewable energy sources. Q2 2026 saw record levels of solar and wind generation, particularly during daylight hours, which often led to periods of very low or even negative wholesale prices. This renewable influx is increasingly displacing more expensive forms of thermal generation, such as coal and gas.
Compounding this effect, domestic gas prices, which significantly influence the cost of gas-fired electricity generation, continued their downward trend from earlier in the year. This relief in gas markets, coupled with strong supply, has reduced the cost input for gas generators operating in the NEM, further contributing to the overall price decline.
What This Means for Your Energy Bill
While wholesale prices have seen a sharp decline, the impact on residential and small business retail electricity bills is not immediate. Energy retailers typically purchase electricity in advance through hedging contracts to stabilise costs and manage risk. This means that recent wholesale price movements take time to flow through to the retail market.
However, sustained lower wholesale prices are a strong indicator that future retail price determinations, such as the Default Market Offer (DMO) and Victorian Default Offer (VDO), will continue to reflect these downward trends. Consumers who are currently on standing offers or older market offers may find themselves paying more than necessary. It is crucial for households to regularly review their electricity plans and compare offers from different retailers. Utilising smart meters can also help track usage and identify potential savings.
For those seeking to proactively manage their energy costs, understanding government support and relief measures remains important. A comprehensive guide to available support can be found at Navigating Australia’s Energy Bill Relief and Support in 2026: A Comprehensive Guide.
Looking Ahead: AEMO’s Outlook
AEMO’s QED report acknowledges that while Q2 delivered favourable price outcomes, the NEM remains dynamic. Factors such as unforeseen plant outages, extreme weather events (particularly during peak winter demand or summer heatwaves), and global energy market volatility could still influence prices. However, the report underscores the increasing resilience of the NEM due to the growing diversification of its energy mix.
The ongoing investment in utility-scale solar and wind, coupled with battery storage projects, is expected to continue moderating wholesale price volatility in the long term. This transition is not only reshaping the energy landscape but is also empowering consumers with more options to manage their energy consumption and costs.

As Australia progresses towards a more electrified future, including the widespread adoption of electric vehicles, the demand for efficient and affordable energy solutions will only grow. Understanding the optimal solar system size for your household, considering future needs like EV charging, is becoming increasingly relevant.
