Looking for a smarter way to stay cool in Queensland and possibly get cashback on your air conditioner? PeakSmart is a program that helps reduce pressure on the electricity grid during peak demand, while keeping your home comfortable. If you are buying a new air conditioner, understanding PeakSmart eligibility can also help you find models that may qualify for cashback in QLD.
What is PeakSmart?
PeakSmart is a Queensland energy program designed to reduce electricity demand during peak periods, especially on very hot days when many households are using air conditioners at the same time. With PeakSmart-compatible air conditioners, Energex can send a signal to slightly reduce the unit’s energy use for a short period, helping keep the power grid stable.
This adjustment happens automatically in the background, and most households will not notice a major difference in comfort.
How does PeakSmart work?
PeakSmart air conditioners use a Demand Response Enabling Device (DRED). This device allows the system to receive signals during periods of high electricity demand and temporarily reduce the energy used by the compressor.
- Automatic operation – No manual setup is needed during peak events.
- Only during peak demand – Adjustments happen when the grid is under pressure, such as during very hot summer afternoons.
- Designed for comfort – Your air conditioner continues running, but may operate at a slightly reduced level.
- Supports grid reliability – Helps reduce the risk of power disruptions across Queensland.
What does PeakSmart control?
PeakSmart mainly affects the compressor, which is the part of the air conditioner responsible for cooling. Instead of turning the unit off, the system adjusts how hard the compressor works during peak demand periods.
There are generally three levels of PeakSmart control:
- Level 1 – Very small adjustment to cooling performance.
- Level 2 – Moderate reduction in compressor output while maintaining comfort.
- Level 3 – Larger reduction during extreme demand conditions, such as heatwaves.
Even during these periods, the air conditioner continues to operate. For most users, the change is minimal.
What are the benefits of PeakSmart?
- Helps reduce pressure on the power grid during high-demand periods.
- Supports a more reliable electricity supply for households across Queensland.
- Works automatically without needing daily attention.
- May qualify for cashback if your air conditioner meets the eligibility requirements.
