Home battery cost and payback in Canada

A home battery can cut your bill, keep the lights on in an outage, or both. It's also one of the more expensive things you can add to a home energy system. Whether it pays depends almost entirely on your rate plan and your province's export rules.

For how batteries work, see home batteries explained. This guide is about the money.

What a battery costs installed

Battery prices aren't tracked by any public Canadian survey we could find, so treat these figures as a rough guide:

• Our model assumes about $1,100 per kWh of capacity installed.
• A Toronto installer's published 2026 pricing put a single 13.5 kWh battery at about $13,000 to $18,500 installed, with about $15,500 as typical. That works out to roughly $1,000 to $1,400 per kWh.

Extra costs can add thousands: an electrical service upgrade from 100 to 200 amps, a long wire run, or a backup panel for the circuits you want powered in an outage. Get a written quote that lists these separately.

Rebates

Ontario: Home Renovation Savings Program

The HRSP battery rebate is $300 per kWh, up to $5,000 and no more than 50% of the cost. The program's own page says:

• The battery must be paired with a new solar system and sized for it.
• It should mainly store solar power, not grid power.
• If you take the HRSP solar or battery rebate, you can't also have net metering.
• You need written pre-approval before you buy or install anything.

Program rules change, so confirm the current terms with the HRSP before you plan around the rebate.

British Columbia: BC Hydro

BC Hydro offers $500 per kWh, up to $1,500 and 50% of the cost, rising to a $5,000 cap if you enrol the battery in its Peak Saver program. Batteries must generally be installed with solar, installers must belong to BC Hydro's contractor network from June 1, 2026, and some brands aren't eligible. Check the program page for the current list.

When a battery pays

Big gaps between cheap and expensive hours

Ontario's Ultra-Low Overnight plan has the biggest price gap in Canada: 3.7¢ per kWh overnight and 37.7¢ on weekdays from 4 to 9 pm.

Here's the best case. A battery charges 11 kWh overnight and delivers about 10 kWh in the weekday peak, after losses. Each weekday saves about $3.35 in energy charges. Over roughly 250 weekdays, that's around $840 a year, before HST and the Ontario Electricity Rebate.

That only holds if your home actually uses 10 kWh between 4 and 9 pm every weekday. Many homes use less. Note too that the HRSP expects a rebated battery to mainly store solar, so ask the program how grid charging fits before you count on these savings.

Even in that best case, the payback is long. A 13.5 kWh battery at $15,000 qualifies for about $4,050 from the HRSP at $300 per kWh, leaving about $10,950. At $840 a year, that takes about 13 years to pay back. Many home battery warranties run about 10 years, so check yours.

Solar that can't export for credit

If your solar system takes the HRSP rebate, power you send to the grid isn't credited. A battery can store that midday surplus for the evening. Each stored kWh saves whatever you'd otherwise pay at that hour, from 9.1¢ to 37.7¢ depending on your plan and the time. Storing 5 kWh a day at Time-of-Use prices saves roughly $270 to $345 a year. Useful, but rarely enough to pay back a battery on its own.

Net billing provinces

In BC (for new customers), Saskatchewan and Manitoba, exports earn less than you pay for power. A battery lets you use more of your own solar. The gain per kWh is the difference between your retail price and the export credit, which is usually too small to cover a battery's cost.

Backup power

Backup has real value if outages are common where you live, if someone at home relies on medical equipment, or if you work from home. It's hard to put a dollar figure on it. See solar during power outages.

When a battery doesn't pay

• You have 1:1 net metering. The grid already stores your summer surplus as credits at full value. A battery adds cost without adding much saving.
• You're on Tiered pricing or a flat rate, where power costs the same at every hour.
• Your evening use is low, so there's little expensive power to replace.
• Your province has cheap power, such as Quebec or Manitoba.

A quick summary

Questions to ask before you buy

• What is the usable capacity in kWh, and how many hours of backup does that give my essential circuits?
• Is the price all-in, including any panel or service upgrade?
• What does the warranty cover, for how many years, and what capacity is guaranteed at the end?
• Does the battery qualify for my province's rebate, and who handles the paperwork?

Common questions

How much does a home battery cost in Canada?

Expect roughly $1,000 to $1,400 per kWh of capacity installed, so about $13,000 to $18,500 for a 13.5 kWh battery. Electrical upgrades can add several thousand dollars.

What battery rebate is available in Ontario?

The Home Renovation Savings Program offers $300 per kWh, up to $5,000 and no more than 50% of the cost. Its page says the battery must be paired with new solar, and you can't also have net metering.

Is a battery worth it with net metering?

Usually not for savings. Net metering already credits your exports at full value, so the grid acts like a free battery. A battery may still be worth it for backup.

How long does a home battery take to pay back?

In the best Ontario case, on Ultra-Low Overnight with high weekday evening use and the HRSP rebate, about 13 years. In most other situations it takes longer than a typical battery warranty.
