What Home Renovation Savings pays for a home battery in Toronto
We re-read the program's solar page and its October 2025 requirements on October 3, 2026. Ontario's rebate is for a battery installed with new solar, not for adding one to an existing system.
Battery storage
Paid per kWh of installed capacity, capped at 50% of eligible costs, including the inverter if applicable and the controls.
Only with new solar
A battery is eligible only when paired with a new solar system and sized for it. A home that already has solar or storage is not eligible.
Solar and battery together
The solar rebate is up to $5,000 and the battery rebate up to $5,000, each capped at half its eligible cost.
No net metering
The system must be sized to offset the home's own use. A net metering agreement makes it ineligible.
Safety and approvals
The installer must be a licensed electrical contractor. The battery must meet the Ontario Electrical Safety Code and fire codes, carry CSA, cUL or UL approvals and have utility connection approval.
Timing
No purchase or install before written IESO pre-approval and utility approval. The project must finish within 12 months and be filed within 30 days of installation.
Toronto HELP loan
A City loan for energy upgrades. Current rates were not re-verified.

Who in Toronto can claim
About 35% of Toronto's 1,160,895 households live in an eligible house type and 52% own. 270,355 are detached households. A condo or apartment owner cannot use this stream, even with a private meter.
Toronto Hydro
Toronto Hydro is the distribution company that must approve the battery's connection. The contractor files the application, and the approval has to come before you buy. Ask Toronto Hydro about the connection process and any size limit.
City loan
Toronto's Home Energy Loan Program can finance upgrades on the property tax bill. We have not re-verified the current rate, and loan interest is not an eligible cost for the rebate.
Already have solar? Not eligible
The program pays for first-time installations only. A home that already has a solar or storage system is not eligible, so an owner who installed panels years ago cannot add a battery and claim this rebate. If you are planning solar and a battery, do them as one project under one pre-installation application.
The kWh arithmetic
The rebate is $300 per kWh, so a 10 kWh battery earns $3,000 and a battery of about 16.7 kWh reaches the $5,000 cap. The rebate is also limited to half the eligible cost, so if the battery costs $8,000 before HST the most you can receive is $4,000. Ask the Toronto installer to show the capacity in kWh and the pre-HST price on the quote.
Where the battery goes
The battery must be installed by a licensed electrical contractor, comply with the Ontario Electrical Safety Code and applicable fire codes, be approved for use in Ontario and pass an electrical inspection. Placement in a garage or basement affects the fire-code review, so ask the installer where the unit will sit and how the clearances were checked.
Approvals and the order of events
The contractor submits the pre-installation application with a quote dated within 60 days. You cannot buy or install before written IESO pre-approval and utility approval. The utility's distributed energy resource approval covers the battery, and the post-installation file needs the connection agreement and the ESA certificate within 30 days of installation.
How to claim in Toronto
- Confirm you own an eligible house type and plan solar and the battery as one project.
- Talk to Toronto Hydro about the distributed energy resource approval for the battery and the maximum size it allows.
- Choose a licensed electrical contractor and ask for one quote covering solar and battery, showing kW, kWh and pre-HST costs.
- Let the contractor file the pre-installation application and wait for written IESO pre-approval and utility approval before buying anything.
- After the install, check that the post-installation application is filed within 30 days with the ESA certificate and connection agreement.
