How to Prepare Your Northern Virginia Home for Power Outages With a Backup Generator

Storms knock out power across Northern Virginia every year. Learn how backup generators work, portable vs standby, and how to keep your home running safely.

Summer thunderstorms, winter ice, and the occasional hurricane remnant all take their turn knocking out power across the region. When the lights go out, a backup generator keeps your refrigerator cold, your sump pump running, and your family comfortable until the grid comes back.

Two Main Types of Backup Power

Portable generators

These are the budget-friendly option. You roll one out, fill it with fuel, and run extension cords or connect through a transfer switch. They cover the essentials but require you to be home, awake, and willing to manage fuel and cords during the storm.

Standby generators

A standby generator is installed permanently outside, wired into your electrical system, and fueled by natural gas or propane. When the power drops, it starts automatically within seconds, whether you are home or away. For many homeowners this is the difference between a minor inconvenience and a ruined freezer full of food.

Why a Transfer Switch Is Non-Negotiable

Never plug a generator directly into a wall outlet. Doing so can push electricity back onto the utility lines and seriously injure a lineworker, and it can damage your equipment. A properly installed transfer switch safely isolates your home from the grid and lets you power selected circuits without any of that risk. This is the part that truly needs a licensed electrician.

Deciding What to Power

The essentials

Refrigerator, freezer, furnace or heat pump controls, well or sump pump, and a few lights and outlets. This is the core most families prioritize.

Whole-home coverage

With a large enough standby unit, you can run air conditioning, the whole kitchen, and every room as if nothing happened. The right size depends on your home and how you live.

Planning Ahead Pays Off

The worst time to think about backup power is during an outage, when generators sell out and everyone needs an electrician at once. Sizing, placement, fuel supply, and permitting all go smoother when there is no storm bearing down.

Good to know

Frequently asked questions

What is the difference between a portable and standby generator?
A portable generator is manually set up and fueled during an outage, while a standby unit is permanently installed and starts automatically within seconds.
Why can't I just plug a generator into an outlet?
Backfeeding through an outlet can electrocute utility workers and damage your equipment. A transfer switch is the safe, code-compliant way to connect a generator.
How big of a generator do I need?
It depends on whether you want to run just essentials or your whole home. An electrician calculates your load to recommend the right size.
Does a standby generator run on natural gas?
Standby generators typically run on natural gas or propane, so you avoid storing gasoline and refueling during a storm.
Will a backup generator start automatically when the power goes out?
A standby generator does, usually within seconds. Portable generators must be started and connected by hand.
Do generator installations require a permit?
Yes. Wiring a transfer switch and connecting a generator to your home requires a permit and inspection, handled by a licensed electrician.
Can a generator power my air conditioning?
A properly sized standby generator can run central air and most of the home, while smaller portable units are usually limited to essentials.
When is the best time to install a backup generator?
Before storm season. Demand and wait times spike during outages, so planning ahead means you are ready when the next storm hits.
