Home Power Outage Checklist (Be Ready Before the Lights Go Out)

Power outages rarely give you warning. When they happen, you either have a plan—or you’re scrambling in the dark. This home power outage checklist gives you a practical, step-by-step plan to prepare before, during, and after an outage so your home stays safe and functional.

Use this as your go-to guide and save a copy for quick reference.

Before a Power Outage: Prepare Your Home

Preparation is what separates inconvenience from disaster. Most damage from outages—flooded basements, spoiled food, frozen pipes—happens because homeowners weren’t ready.

Backup Power Plan

Start with a reliable power source.

  • Portable generator or battery backup
  • Fuel supply (if using generator)
  • Heavy-duty extension cords
  • Transfer switch (recommended)
