Queensland households and small businesses are set to face optional demand and flexible load tariffs from mid-2027, after the Australian Energy Regulator (AER) rejected a bid by network operators Ergon Energy and Energex to remove these tariff options. The AER’s final decision, released on 30 October 2026, upholds the planned introduction of these cost-reflective tariffs for the 2025–30 regulatory period, marking a significant step towards managing Queensland’s grid stability and peak demand.

The decision means that while the network companies, both subsidiaries of Energy Queensland, sought to amend their tariff structure statements to scrap the optional tariffs, the regulator determined their request did not meet the necessary criteria under the National Electricity Rules. This outcome solidifies the trajectory towards more granular, consumption-based pricing for a substantial portion of Queensland’s 2.3 million electricity customers.

What the AER Decision Means for Queenslanders

Ergon Energy, covering regional Queensland, and Energex, serving the south-east, had submitted requests on 22 May 2026 to remove certain optional tariffs from their approved 2025–30 tariff structure statements. These tariffs were originally planned to be introduced during the regulatory control period. The AER, after consultation, found that the networks failed to demonstrate an “unforeseen event” outside their control, or that the proposed amendments would “better meet the pricing principles” than the existing approved statements.

“As a result of our decision, the current approved tariff structure statements for Ergon Energy and Energex, which commenced on 1 July 2025, will continue to apply for the duration of the 2025-30 regulatory period.”

This confirms that the existing framework, which includes the optional tariffs, will remain in place. For residential and small business customers, this translates to:

  • Optional Demand Tariffs: Available from 1 July 2027.
  • Optional Flexible Load Tariffs: Available from 1 July 2028.

It is crucial to understand that these are optional tariffs, offered through electricity retailers, not directly imposed by the network operators. This means consumers will have the choice to opt into these tariffs, provided their retailer offers them. The AER’s decision underscores a broader commitment from Queensland’s networks and regulator to implement cost-reflective pricing over the current regulatory period.

Understanding Demand and Flexible Load Tariffs

Demand tariffs charge customers based on their highest electricity usage (peak demand) within a specific period, typically measured in 30-minute intervals. Unlike traditional flat-rate or time-of-use tariffs that focus solely on the volume of electricity consumed, demand tariffs incentivise consumers to manage when and how much power they draw from the grid simultaneously. For example, simultaneously running an air conditioner, electric oven, and electric vehicle charger during a hot summer evening could trigger a high demand charge.

Flexible load tariffs, on the other hand, are designed to encourage consumers to shift their electricity consumption to periods of lower demand or higher renewable energy generation. This could involve smart appliances or home energy management systems automatically adjusting their operation based on grid signals or pricing. These tariffs are vital tools for modern grids, helping to:

  • Improve Grid Stability: By smoothing out peak demand, they reduce stress on transmission and distribution infrastructure. This is particularly important as more intermittent renewable energy sources come online.
  • Reduce Network Costs: Less investment is needed in costly network upgrades to meet infrequent peak demand events.
  • Lower Wholesale Prices: Reduced peak demand can lead to lower wholesale electricity prices across the National Electricity Market (NEM).

Queensland’s Energy Landscape and Future Implications

Queensland’s energy sector is undergoing significant transformation. The state’s Energy Roadmap, released in October 2025 by the Crisafulli Government, outlines a new direction focused on ensuring affordability, reliability, and sustainability. While the roadmap adjusted previous renewable energy targets, it also emphasised improving existing infrastructure and integrating new generation sources responsibly.

The introduction of demand and flexible load tariffs aligns with the broader objectives of grid modernisation and efficiency. By encouraging consumers to actively participate in demand management, Queensland aims to better integrate its growing renewable energy capacity, which includes substantial rooftop solar installations—exceeding 1.16 million households and businesses with a combined capacity of 7.2 GW.

This regulatory decision impacts how future energy investments and consumer behaviour will shape Queensland’s electricity grid. For those with solar panels, or considering a home battery, understanding these tariffs becomes increasingly important. Optimising energy usage to avoid high demand charges can unlock significant savings.

Preparing for the Change: What Queensland Consumers Can Do

While the optional demand tariffs are still some months away, proactive steps can help Queensland residents and small businesses prepare:

  1. Understand Your Usage: Begin to monitor your household or business’s electricity consumption patterns, particularly peak usage times. Smart meters, if installed, can provide this data.
  2. Evaluate Retailer Offers: When demand tariffs become available from July 2027, compare electricity retailers to see which ones offer plans that align with your usage habits and allow you to benefit from these new tariff structures. You can start by reviewing guides like Compare Electricity Retailers 2026: Unlock $150+ Annual Savings in Australia and Best Australian Electricity Plans in 2026 to Save Up to $450.
  3. Optimise Solar and Storage: If you have rooftop solar, consider how you can use generated power more effectively to reduce reliance on grid electricity during potential peak demand windows. For those considering solar, understanding these future tariffs can influence system sizing and battery integration. More information on costs and rebates can be found in guides like How Much Does a 6.6kW Solar System Cost in Australia in 2026? Your State-by-State Guide to Prices & Rebates.
  4. Embrace Smart Technology: Smart appliances, timers, and home energy management systems can help automate shifting high-load activities (e.g., washing machine, dishwasher, EV charging) to off-peak or solar-rich periods, mitigating potential demand charges.

This AER decision reinforces the energy market’s evolution towards more cost-reflective pricing. While it presents a new layer of complexity, it also offers opportunities for informed consumers to manage their electricity bills more effectively and contribute to a more stable and efficient grid.
