What Home Renovation Savings pays for a home battery in Vaughan
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.

The requirements document gives no end date for this stream, so confirm on the program page before you sign. The IESO has no pre-qualified contractor list.
Alectra
Alectra Utilities approves the battery connection. Ask what the process looks like for a load-displacement system with storage.
Why Vaughan fits
Only 8% of households live in homes built before 1981, and 86% own. A newer house is more likely to have a roof with years of life and an electrical panel with spare capacity, but the installer must confirm both.
Battery size
The rebate pays $300 per kWh up to $5,000, so about 16.7 kWh reaches the cap. A larger battery adds cost without adding 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.
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.
What counts as eligible cost
Eligible costs cover equipment, permits, approvals and labour, including the inverter if applicable and necessary controls. HST, financing, insurance, maintenance and spare parts are not eligible costs, and combined funding from other sources cannot exceed 100% of the cost.
How to claim in Vaughan
- Confirm you own an eligible house type and plan solar and the battery as one project.
- Talk to Alectra Utilities 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.
