Power outage map for every US state and the UK

The first hour of an outage

1. Check it is not just your home. Look at your breaker panel or consumer unit, then your utility's map above. If your street is not shown, report it.
2. Keep the fridge and freezer shut. Our checklist explains how long food stays safe, and the fridge runtime calculator shows how long a power station can keep yours running.
3. Power medical devices first. See how long a battery runs a CPAP with the runtime calculator, CPAP preset.
4. Run generators outdoors only. Read the generator safety rules before starting one, and check you have a big enough generator for what you plan to run.
5. Protect electronics. Unplug sensitive devices so a surge when power returns cannot damage them, as covered in our checklist.

Once the lights are back, take the outage readiness quiz or print the one page checklist so the next one is easier. To see what your appliances draw, use the appliance wattage chart.

Frequently asked questions

Is there one official power outage map for the whole US?

Outage maps are run by each electric utility for its own customers, so the official map for your address is your utility’s own. Third party trackers collect those figures into national views, but reports, restoration estimates and updates for your home come from your utility. Find it by state on this page.

How do I report a power outage?

Report it to your electric utility, not your retail supplier, using its outage page, app or phone line. Most of the maps linked here have a report button. In England, Scotland and Wales you can also call 105 free, and it connects you to your local network operator.

Who do I call in a UK power cut?

Call 105 from anywhere in England, Scotland or Wales. It is free and puts you through to the network operator that runs the cables in your area. In Northern Ireland, NIE Networks lists 03457 643 643 as its customer helpline.

Why is my energy supplier not on the UK list?

Your supplier sends the bill, but a separate network operator owns the cables, overhead wires and substations that bring power to your street. Power cuts are handled by the network operator, which is why the UK list shows those companies and their power cut maps.
