When the peak event starts, reduce your power usage as much, and as safely, as you can for the two-hour period to maximise your opportunity to meet your reduction targets. Please note, your reduction targets are based off your normal usage patterns during the time of a peak event period.

Your safety is most important, and any energy reduction activity should be done in a safe manner. Do not turn off any vital appliances or devices.

What can you do before the peak event starts?

Pre-cool your home

A few hours before the event starts, turn on the air conditioner and set the temperature between 24–26°C. This will minimise the need to cool during a peak event.

Shut external facing doors and close curtains

Up to 25% of household heating or cooling loss is from improper seals. Close your doors, rest draught blockers along the bottom of the doorframes or seal cracks around your windowsills to make sure your house stays at a more consistent and comfortable temperature. By closing curtains and blinds you can also block out some of the summer heat.

Close doors to any unoccupied rooms

Close doors to any unoccupied rooms (like bathrooms and the laundry). This can help to efficiently maintain the temperature in areas you’re using. If you have ducted cooling, close vents in unused rooms to create zoned areas in your home.

What can you do during the peak event?

Manage your cooling 

Use a fan to circulate the air (fans can use around 20 times less energy per hour to run than air conditioners and typically reduce the temperature by 2°C or 3°C), which may be enough to keep you comfortable. 

Set your air conditioner thermostat to between 24–26°C, as every degree below can add up to 10% to its usage and make it harder to reach your peak event targets.

Delay the use of appliances

To maximise your energy reduction during a peak event, shift the use of appliances like the dishwasher, electric oven and microwave to before or after the two-hour peak period. 

Switch off unnecessary lights

Turning off nonessential lights during a peak event can help ensure you reduce your usage.

Save energy on how you wash and dry clothes

Wash a full load of laundry in cold water, rather than hot water, as it uses less energy. You can also save by making sure you select the shortest appropriate washing cycle, in most washing machines this is the “eco” setting. Avoid using a clothes dryer and make the most of that warm summer weather by hanging clothes outside and letting them dry naturally. By doing this you can typically save up to 3-4 kWh in energy use (based on 5kg capacity / 3-star rating). 

Switch off the pool pump

Switching off your pool pump during an event could save you 1-2 kWh (based on 1.2kW pool pump / 3 star-rating), and in some instances it could be all you need to do to achieve the minimum reduction target!

How much electricity do my appliances use?

You can find out how much power your appliances use by checking the label or instruction manual. Input power will be displayed in watts (W) or kilowatts (kW). Once you have established the appliance's input power, you can manually calculate operating costs:

  1. Check the appliance's input power in watts or kilowatts, e.g. 2000W

  2. Convert it to kW by dividing it by 1,000; e.g. 2000W divided by 1,000 = 2kW

  3. Find your usage tariff by checking your bill, e.g. 30 cents per kWh (Kilowatt hour)

  4. Multiply the input power by your energy tariff to find the hourly running cost. E.g. 2kW x 30 cents = 60 cents per hour
