Frequently Asked Questions

Your microwave is off. Your dishwasher finished hours ago. Your dryer is sitting idle. But they are all still using electricity. It is called phantom power also known as standby power, vampire power, or phantom load and it accounts for roughly 5 to 10% of the average Canadian household’s electricity bill. In Nova Scotia, where residential rates sit around 18.2 cents per kWh, that is real money draining from your wallet every month.

What Is Phantom Power?

Phantom power is the electricity an appliance draws while it is plugged in but not actively in use. Any device with a standby light, clock display, remote control receiver, or Wi-Fi connection is pulling power around the clock even when you think it is off. This is not a design flaw. These devices need a small amount of power to maintain memory, respond to remote signals, or keep a clock running. But across a whole household of appliances, it adds up fast.

Which Appliances Are the Worst Offenders?

Appliance	Standby Draw	Annual Cost (NS)
Cable / satellite box	15 to 30W	$24 to $48
Game console (instant-on)	10 to 25W	$16 to $40
Desktop computer + monitor	5 to 15W	$8 to $24
Smart TV	5 to 15W	$8 to $24
Microwave (clock display)	2 to 5W	$3 to $8
Dishwasher (control board)	1 to 4W	$2 to $6
Washer / dryer (smart models)	1 to 5W each	$2 to $8 each

Did you know? Your cable or satellite box is likely the single biggest phantom power draw in your home consuming 15 to 30 watts even while “off.” That one device alone can cost $24 to $48 per year on your NS Power bill, running 24 hours a day, 365 days a year.

What Does Phantom Power Actually Cost in Nova Scotia?

For a typical Halifax home with roughly 40 to 50 watts of phantom draw running around the clock very common with a TV, cable box, microwave, coffee maker, washer, and a couple of chargers – here is the math:

45W x 24 hours x 365 days = 394 kWh per year
394 kWh x $0.182 = approximately $72 per year

That is $72 per year for electricity you are not using. Not catastrophic, but not nothing either especially as Nova Scotia Power rates continue to climb.

How to Reduce Phantom Power at Home

Pro tip: The easiest single move to cut phantom power is a switched power bar for your entertainment centre. One flip of the switch kills phantom draw from your TV, cable box, game console, and streaming stick simultaneously. That one change can save $40 to $60 per year at Nova Scotia rates.

Use power bars with switches – plug your entertainment centre or computer setup into a switched power bar and flip it off when not in use
Unplug chargers when not charging – phone, laptop, and tablet chargers all draw small amounts even when nothing is attached
Use smart power strips – these automatically cut power to peripheral devices when the main device (like a TV) is turned off
Disable instant-on features – game consoles and smart TVs have options to fully shut down instead of entering standby; a few extra seconds of boot time in exchange for lower electricity use
Do not worry about the fridge – your fridge needs to stay plugged in; same for your router and modem; focus energy on discretionary entertainment devices

Should You Unplug Kitchen Appliances?

For most people, unplugging and replugging the dishwasher, washer, and dryer every day is not practical and the savings are small, a few dollars per year per appliance. The bigger wins come from entertainment devices and phone chargers left plugged in indefinitely.

However, if you are going on vacation for a week or more, unplugging non-essential appliances is a smart move. It also protects them from power surges during Nova Scotia storms- a surge through a plugged-in appliance can damage control boards and cost hundreds in repairs. If you suspect any surge-related damage or performance issues, it’s best to schedule a professional appliance repair service to prevent further problems and costly breakdowns.

Phantom Power and Modern Smart Appliances

Smart appliances, Wi-Fi connected fridges, washers with app control, smart ovens draw more standby power than their non-smart counterparts because they need to maintain a Wi-Fi connection and listen for commands. A Samsung smart fridge or LG ThinQ washer may draw 5 to 10W in standby compared to 1 to 2W for a basic model. That is an extra $8 to $16 per year per appliance. The convenience may well be worth it, but it is worth knowing.

 Trustindex verifies that the original source of the review is Google. The central portion of a dual element on our Samsung range had failed.  Initially it looked like a switch had burnt out but on further investigation by the technician he found that it was the central element that had burnt out also.  Vadym is a very good technician.  Parts were ordered and they arrived very quickly.  One part had to be reordered because it was damaged during shipping but a replacement part came quickly.  After the repairs were done Vadym gave many tips on the care of the Samsung range and the other appliances in our home. Overall an excellent job.

Frequently Asked Questions

What is phantom power and why does it matter?

Phantom power (also called standby power or vampire power) is the electricity a device consumes while plugged in but not actively in use. It matters because it is continuous running 24 hours a day, 7 days a week and it adds up across all the devices in your home. In Nova Scotia, phantom power typically costs a household $50 to $100 per year on their NS Power bill, sometimes more.

Which household appliances use the most phantom power?

The biggest phantom power offenders are cable and satellite boxes (15 to 30 watts), game consoles with instant-on mode (10 to 25 watts), desktop computers in sleep mode (5 to 15 watts), and smart TVs (5 to 15 watts). Kitchen appliances like microwaves and coffee makers with clock displays use 2 to 5 watts each. Appliances without displays or standby modes – basic toasters, kettles use virtually nothing when off.

How much does phantom power cost per year in Nova Scotia?

A typical Halifax home with 40 to 50 watts of combined phantom draw pays roughly $65 to $80 per year for electricity it is not actively using. At Nova Scotia Power’s rate of approximately 18.2 cents per kWh, each watt of continuous phantom draw costs about $1.59 per year. A cable box drawing 20 watts costs around $32 per year in standby alone.

Does unplugging appliances when not in use actually save money?

Yes, but the savings vary by device. Unplugging a cable box and game console when not in use can save $50 to $80 per year. Unplugging a dishwasher or dryer saves $2 to $6 per year not worth the hassle. The highest-impact targets are entertainment devices, phone chargers left plugged in permanently, and any device with a large external power brick. Focus there for the best return.

Can phantom power damage an appliance or cause a fire?

Phantom power itself does not damage appliances or cause fires under normal conditions. However, appliances left plugged in are exposed to power surges during storms and grid fluctuations Nova Scotia is not immune to these. A surge can damage a control board, especially on modern appliances with sensitive electronics. Using a surge protector power bar protects against this. If an appliance feels unusually warm while idle or you notice a burning smell, unplug it and call a technician.
