What is standby power?
Standby power or ‘phantom load’ as it’s sometimes called, refers to electricity that is consumed by appliances that are not in use. Standby power essentially means your appliances are ready to be used at any point, however this means paying for electricity that you’re not using.
How much does standby power cost?
According to Canstar Blue data, standby power could cost you as little as 0.03c per hour for a computer monitor to as much as 0.54c per hour for a smart TV, depending on a myriad of factors, including your location, the rate you pay for power and the energy efficiency rating of your appliance.
The costs above only refer to one appliance in use, but it is likely that households would have multiple appliances potentially using standby power at any time. To help your understanding of standby power costs throughout the home, we have listed some common household appliances and their hourly standby usage amounts and costs.

As shown in the table above, the most expensive appliances for standby power are typically tech devices, such as your TV and game console. Wireless modems can also add a hefty amount to your energy bill, though it’s not technically on standby and it might be impractical for you to switch off the internet every night.
That said, you can see how these small standby electricity expenses can add up when forgotten about. So how much could standby costs be adding your energy bill each year? We’ve taken a look at the annual costs for these devices, using the same metrics as the table above.

Think standby power won’t cost you that much? Our data above suggests households with all the appliances listed could be unknowingly adding between $104.07 and $176.99 to their energy bills each year, depending on location. But no need to panic! Let’s take a look at why this may be the case and what you can do to crunch those numbers down.
Why do appliances use electricity on standby?
If an appliance has a remote control, LED light, digital clock, touch-on button, or similar function, then you can bet it uses standby electricity. The amount of electricity that feeds into the device will be absolutely miniscule – just enough to power its sensors so it can be switched back on.
Some of the more expensive devices to leave on standby are ones which run background functions. Take a gaming console for example. Many new consoles will regularly run Wi-Fi checks, download content and be ready for remote, touch or voice activation. This will inevitably consume electricity while in standby mode and may add some unexpected costs to your power bill.

How to reduce standby energy costs
Think of standby electricity as a leaky tap. Even if it doesn’t bother you, it’s still a waste that you should try to mitigate. Here are a few tips to reduce your standby electricity wastage:
Turn off appliances at the wall
Switching off appliances at the point is a guaranteed way to ensure your electricity bill isn’t inflated by phantom load.
Smart boards
Some electricity boards are able to detect when an appliance has entered standby mode and will cut its electricity feed entirely. It will also detect when you’re trying to turn the device back on and recommence its feed of electricity.
Energy efficient models
The energy efficiency star ratings system is intended to indicate electricity usage running costs, but it also helps provides a useful guide to standby costs. The more energy efficient an appliance is, the less electricity it will use on standby.
Adjust standby settings
You can modify the settings on some smart televisions and smart consoles to minimise their standby functionality. Use this to stop them from scanning for Wi-Fi when on standby.
If you are looking to reduce your energy use as a means to save money on your bills, a major contributor to unnecessarily big bills is being on the wrong electricity plan. Comparing your current energy plan with the cheapest on the market is a good place to start. Click on the Canstar Blue link below to start comparing now.
