How much you get
Battery alone
$300/kWh, capped at 50% of total system cost.
Battery + solar, combined
Both rebates stack on the same behind-the-meter project.
Ottawa's more severe winter ice storms (vs. Toronto) make battery backup a more practical resilience play here, independent of the rebate math.
How to claim it
- Confirm eligibility via a quick form
- Select a contractor and get written pre-installation approval
- Installation is completed
- Rebate arrives after the contractor submits documentation

Ottawa hasn't forgotten the derecho, and neither has its tree canopy
Ask anyone who lived through May 2022 in Ottawa and they'll tell you the same thing: the derecho didn't just cut power for over a week in some neighbourhoods, it stripped out mature trees the city had grown for decades, and the canopy still hasn't fully recovered. Hydro Ottawa's storm response since then has been busy. An August 2026 severe thunderstorm alone knocked out power to roughly 28,000 customers, mostly from wind-felled branches in the west end and Nepean. That pattern (fewer old trees overall, but the ones still standing near lines are now more exposed and more likely to come down in the next big wind event) is part of why battery interest has picked up here beyond the usual solar crowd.
Battery-only still gets nothing from the province
The Home Renovation Savings Program's $300/kWh battery rebate, capped at $5,000, only applies when the battery rides along with a solar installation. Combined with solar's own $5,000, the ceiling is $10,000. Ottawa's climate resiliency planning treats distributed battery storage as a genuine tool: the city's Climate Ready Ottawa strategy names severe wind and ice storms as priority risks over its 2026-2030 action window, and Energy Evolution, the city's broader energy strategy, leans on rooftop solar and storage as part of hitting its 2050 targets.
Hydro Ottawa's own winter outage guidance is a good starting point for sizing a system, since it lays out what typically causes the longest restoration times here: usually ice loading on lines, not just wind. On r/ottawa, the recurring question after each storm cycle isn't whether outages are getting worse (people mostly agree they are), it's whether a $3,000-4,000 battery investment beats a $1,500 generator for a house that loses power maybe twice a year for a few hours at a time. For most people the honest answer depends more on whether they already have solar than on the outage itself.
Common questions
Is there a home battery rebate in Ottawa?
Not as a standalone purchase. The Home Renovation Savings Program pays $300/kWh, capped at 50% of cost, only when a battery is added to a solar installation. Buy just the battery and there's no provincial money attached.
After the 2022 derecho, do Ottawa homeowners actually need a battery?
The May 2022 derecho left parts of Ottawa without power for over a week and killed a huge share of the city's mature tree canopy, and Hydro Ottawa has since dealt with repeat multi-thousand-customer storm outages, including roughly 28,000 customers out during an August 2026 thunderstorm. A whole-home generator handles that scale of outage better than most batteries, but a battery sized for fridge, sump pump, and networking gear covers the far more common shorter outages without fuel storage or a permit.
