Power Outage History by ZIP Code
Enter your ZIP code to see the outage history for your county — built from 3046 US counties and 2014–2025 of real Dept. of Energy outage data, not estimates.
How ZIP code lookup works
Your ZIP code is matched to the county it sits in using the Census Bureau's public ZCTA-to-county crosswalk. From there you get that county's full outage record: how many outages were recorded between 2014 and 2025, how long they typically lasted, a reliability grade compared against every other county nationally, and generator recommendations sized to that county's actual outage history.
FAQ
Can I look up power outage history by ZIP code?
Yes. Enter any 5-digit US ZIP code above and we'll match it to its county and show that county's full outage history: total recorded events, average and worst outage duration, and a reliability grade (A-F) based on 12 years of real Dept. of Energy data.
Why does ZIP code search show county-level data instead of my exact ZIP?
Utilities and federal regulators report outage data at the county level, not by individual ZIP code — there is no publicly available dataset that tracks outages ZIP-by-ZIP nationwide. We map your ZIP code to its county using the US Census Bureau's ZCTA-to-county relationship file, then show you the real, recorded outage history for that county.
What if my ZIP code spans more than one county?
A small number of ZIP codes straddle a county line. In that case we show the county that contains the larger share of that ZIP code's land area, which is the standard approach used by the Census Bureau's own crosswalk file.
How far back does the outage data go?
The underlying dataset (ORNL EAGLE-I) covers 2014 through 2025 — 15-minute snapshots of customers without power, reconstructed into discrete outage events. See our methodology page for full detail on how events and reliability grades are computed.
