Every major BC windstorm brings the same search spike: "home battery backup power outage." Fair — nothing focuses the mind like sitting in the dark. Here's a realistic, non-hyped answer to what a battery actually keeps running, and for how long.
What a typical home battery can power
Most residential batteries installed in BC (10–13 kWh capacity) are sized to run your home's essential circuits — not your entire house at full draw, but the things that matter during an outage:
- Fridge and freezer (protects hundreds of dollars in food)
- Lights
- Your furnace or heat pump's electronic controls and blower
- Wifi router and a few outlets for phones, laptops, medical devices
Depending on system size and what's running, that's typically 8 to 24+ hours of backup — and if it's paired with solar, that window extends every sunny day the outage continues.
What it costs to be without one
The real cost of a multi-day outage isn't dramatic — it's a few hundred dollars in spoiled groceries, a hotel night if your heat is out and it's freezing, and for some households, a genuine safety issue if someone depends on powered medical equipment. None of that shows up on a spreadsheet until it happens to you.
How this connects to the rebate
The BC Hydro rebate exists specifically to encourage this kind of resilience at the household level — up to $5,000 toward a battery, plus Peak Saver rewards for keeping it enrolled in the grid's demand-response program. The rebate is the financial case; outage protection is the actual reason most BC homeowners pull the trigger.
Sizing tip: talk to your installer about which circuits actually need backup. A smaller, correctly-scoped system covering your essentials is usually a better value than an oversized system trying to run everything.
