Standby vs Portable Generator: Which Is Right for an Alberta Home?

Every Albertan who has lived through a January cold snap knows the sinking feeling when the power blinks off. The furnace stops, the sump pump stops, and if you're on a well, your water stops too. The question isn't whether you need backup power, it's which kind actually fits how you live. We get asked about this constantly, especially from folks out in Sherwood Park, St. Albert, and the acreages ringing Edmonton where outages tend to last longer. Here's the honest breakdown of standby versus portable, so you can make the call that's right for your property and your budget.

The Real Difference Between the Two

A portable generator is exactly what it sounds like. It sits in your garage or shed until you need it, then you wheel it out, fuel it up, and run extension cords to whatever needs power. They cost less upfront, they're flexible, and they work fine for short outages if you're willing to do the setup yourself in the dark and cold.

A standby generator is permanently installed outside your home, wired directly into your electrical panel, and set to start automatically within seconds of losing utility power. No cords, no fuelling at 2am in a snowstorm, no guessing which circuits are safe to run. It just works, whether you're home or away.

The trade-off is straightforward: portables are cheaper and more flexible, standbys cost more but deliver real peace of mind and hands-off reliability.

What a Transfer Switch Actually Does (and Why You Need One)

This is the part people skip and shouldn't. A transfer switch is the device that safely connects your generator to your home's electrical system. Without one, running a generator by plugging it into an outlet or jury-rigging it to your panel can send power backward into the utility grid, a phenomenon called backfeeding.

A transfer switch isolates your home from the grid the moment the generator kicks in, so power only flows one direction. Standby systems come with an automatic transfer switch built into the setup, which is part of why they're so seamless. If you go portable, you still need a manual transfer switch installed for the same reason, plus it lets you power your panel directly instead of running a dozen cords through a window. Our team handles the full setup, from panel assessment to switch installation, through our generator and transfer switch service.

Sizing Basics: How Much Power Do You Actually Need

Generator sizing comes down to what you want to keep running. There are three general tiers:

• Essentials only (furnace, fridge, sump pump, some lighting) usually needs a smaller unit, often in the 7,000 to 10,000 watt range.
• Most of the house (essentials plus well pump, some plugs, garage) typically calls for 12,000 to 20,000 watts.
• Whole home coverage, including AC, electric range, or a shop, often needs 22,000 watts or more.

Furnaces, well pumps, and sump pumps all have a startup surge that's much higher than their running wattage, so sizing isn't just adding up appliance labels. This is where we walk through your panel and your must-run list with you before recommending a size, since an undersized unit will trip constantly and an oversized one is money you didn't need to spend. If your panel is older or already maxed out, it's also worth asking whether a panel upgrade should happen at the same time.

Fuel Options: Natural Gas, Propane, or Gasoline

Portable generators mostly run on gasoline, which is cheap and available everywhere, but gas goes stale in storage and you need enough on hand to last the outage, which in an Alberta winter storm could be days.

Standby generators typically run on natural gas or propane. Natural gas is the popular choice for homes already on the gas line, since it means unlimited fuel with no tank to refill and no gas cans in the garage. Propane is the go-to for acreages and rural properties without natural gas service, run off a dedicated propane tank sized for your generator's runtime needs. Both are cleaner burning and more stable in storage than gasoline, which matters when a generator might sit unused for months between outages.

Why Acreages and Rural Properties Lean Standby

If you're on municipal services in central Edmonton, a short outage is an inconvenience. If you're on an acreage near Sherwood Park, Leduc, or Beaumont, an outage often means no well water, no furnace, and no way to run the shop or livestock waterers, and repair crews reach rural lines last. Outages out there also tend to run longer, sometimes a full day or more after a bad windstorm or ice event.

That combination, higher stakes and longer waits, is exactly why acreage owners tend to invest in standby systems rather than portables. An automatic standby generator means your well pump and furnace come back online in seconds, whether you're home, at work, or away for the weekend. For properties with a shop, workshop, or additional outbuildings, sizing gets more involved too, which is another reason to have someone walk the property with you rather than guess from a spec sheet online.

We install and service standby systems throughout the Sherwood Park area and the surrounding acreages, and we're happy to come take a look at your panel and property to talk through what actually makes sense for your situation.

Making the Call

If you want the cheapest option for the occasional short outage and don't mind manual setup, a portable generator with a properly installed manual transfer switch is a reasonable choice. If you're on an acreage, have a well, work from home, travel often, or you're simply tired of the stress every time the wind picks up, a standby generator is the better long-term investment.

Either way, the transfer switch and the sizing are not places to cut corners. That's the part that keeps your family, your home, and utility workers safe.
