Queensland’s wholesale electricity market experienced a significant price reduction in the 2025-26 financial year, with average prices plummeting by 40% to AU$65.47 per megawatt-hour (MWh). This substantial drop, reported by state-owned generator CleanCo Queensland, is directly attributed to the rapid expansion of utility-scale battery storage across the state. The news, published on 1 October 2026, highlights a pivotal shift in the energy landscape, offering a potential easing of cost pressures for consumers and businesses in Queensland.
CleanCo Queensland’s annual report for FY26, tabled in the Queensland parliament in late September, revealed that wholesale prices fell from AU$109.54 per MWh in the previous financial year to the new average of AU$65.47 per MWh. This represents a marked contrast to the escalating wholesale costs seen in recent years and underscores the increasing influence of renewable energy and energy storage solutions on market dynamics.
“Queensland’s average wholesale electricity price fell by 40% in the 2025-26 financial year, a drop the state’s government-owned generator, CleanCo Queensland, attributes directly to the rapid build-out of utility-scale battery storage across the state.”
The Role of Battery Storage in Price Stabilisation
The integration of large-scale battery energy storage systems (BESS) is proving instrumental in stabilising and reducing wholesale electricity prices. These batteries absorb excess renewable energy during periods of high generation (typically midday solar peaks) and discharge it back into the grid when demand is high and generation is lower (such as evening peaks). This ‘load shifting’ capability helps to smooth out price volatility and reduce the reliance on more expensive, fast-start fossil fuel generators.
While wholesale prices do not directly translate to immediate, equivalent reductions in household or business retail electricity bills, a sustained downturn in the wholesale market creates a favourable environment for retailers to offer more competitive plans. Queensland households on standard offers have already seen some relief, with residential flat rate standing offer prices decreasing by 7.2% in South East Queensland from 1 July 2026, according to the Australian Energy Regulator’s (AER) Default Market Offer (DMO) final determination. Small businesses in South East Queensland also experienced reductions of 10.4% to 14.0%.
However, it’s crucial for consumers to remain proactive. The AER consistently advises that the Default Market Offer is a safety net, and competitive market offers often provide better value.

Broader Market Context and Future Outlook
The Queensland price drop is part of a broader trend where increasing renewable penetration and battery deployment are influencing the National Electricity Market (NEM). The latest wholesale electricity market report from the AER indicated that wholesale electricity prices fell across all NEM regions in 2025, with South Australia, for instance, seeing an average wholesale price fall from $132.50/MWh in 2024 to $113.91/MWh in 2025.
This shift is not without its challenges. While mid-day wholesale prices can dip significantly, even to zero or negative values due to abundant solar, the market dynamics are evolving. Recent analysis from 8 October 2026 noted that over the past 30 days, NEM prices averaged $68/MWh, up from $59 a year earlier, with midday prices rising from around zero to $25–30/MWh. This indicates that while batteries reduce evening peaks, their charging behaviour can sometimes influence midday prices.
For businesses, particularly those with significant energy consumption, understanding these market shifts is vital. Reviewing current pricing and contract structures is important as market conditions continue to improve. The move towards cleaner, firmed energy sources is reshaping the cost components of electricity, making strategic energy management more critical than ever.

How Queensland Compares
To provide context, here’s a snapshot of typical residential electricity usage rates and daily supply charges across major Australian regions as of early October 2026:
| Region / Network | Typical Usage Rate (c/kWh, inc GST) | Typical Daily Supply Charge (c/day, inc GST) | Median Annual Bill (approx.) |
|---|---|---|---|
| Energex (SE QLD) | 27.97c | 185.97c | $1,986 (4,600 kWh) |
| Ausgrid (Sydney, NSW) | 32.8c | 153.73c | $1,802 (3,900 kWh) |
| CitiPower (Melbourne, VIC) | 25.85c | 113.85c | $1,411 (4,000 kWh) |
| Aurora Energy (TAS) | 26.2c (average 2026) | 98c (average 2026) | $1,340 (average 2026) |
Note: These figures represent median generally available single-rate market plans and typical usages for benchmarking purposes as of 9-10 October 2026. Actual bills vary based on consumption, tariff, and retailer.
While Queensland’s retail rates remain competitive, the significant reduction in wholesale costs provides a strong foundation for continued downward pressure on consumer prices. The ongoing investment in grid-scale batteries, alongside other renewable infrastructure, is demonstrably reshaping Australia’s energy cost landscape.
