Why a Tesla Powerwall in Canada
Canadian homes get two things from a Powerwall: protection and savings. Winter storms and grid outages are common, and a Powerwall keeps your home running when the power drops. On top of that, most provinces price electricity by time of day, so a battery that charges cheap and discharges expensive trims your bill every month. Pair it with solar and you store your own clean power for the evening instead of selling it back for less.
How a Powerwall saves you money on time-of-use rates
A Powerwall lets you buy power when it is cheap and use it when it is expensive. It charges from your solar panels or the grid during low-cost off-peak hours, then powers your home during pricey on-peak hours. The Tesla app does this automatically, so you capture the savings without thinking about it.
| Rate plan | Off-peak | On-peak |
|---|---|---|
| Ontario time-of-use | 7.6 c/kWh | 15.8 c/kWh |
| Ontario Ultra-Low Overnight (ULO) | 2.8 c/kWh | 28.6 c/kWh |
Rates and time-of-use windows vary by province and utility. Figures are illustrative.

Tesla Powerwall FAQ
What is a Tesla Powerwall?
The Tesla Powerwall 3 is a home battery that stores energy from your solar panels or the grid. It powers your home during outages and during expensive on-peak hours, and it is managed automatically through the Tesla app.
How does a Tesla Powerwall work?
It charges when power is cheap or when your panels are producing, then discharges that stored energy when you need it. During a grid outage it switches your home to battery power instantly and keeps your essentials, or your whole home, running.
How long can a Tesla Powerwall power a house?
One Powerwall stores 13.5 kWh. That typically runs essential loads like the fridge, lights, internet, and furnace fan for a day or more, or your whole home for several hours. Stacking multiple Powerwalls extends that backup further.
How many Powerwalls do I need?
Most homes start with one Powerwall for essential backup and time-of-use savings. Larger homes, or those that want whole-home backup for longer outages, often add a second or third. A certified installer sizes it to your usage and budget.
