What is read, and how

The live pages add up customers without power from public sources every 15 minutes. This page lists those sources and explains how they are read. Any one source can be switched off without a code change, and all of them at once. For the live health of every source and the current coverage, see the command center.

Sources

• ODIN, the Outage Data Initiative Nationwide at Oak Ridge National Laboratory: outages that utilities send to the Department of Energy, summarised by county on ODIN's public endpoints.
• Utility outage maps that publish their data as public files, read the same way a browser showing the map reads them. Each map's own page is linked from the live tables.
• National Weather Service warnings in effect during a large outage, shown as context.

How they are read

• Once every 15 minutes, from one server, with a user agent that names this site and links to this page.
• At most four requests at a time to any one host. A map whose data has not changed since the last reading is not downloaded again.
• A source that fails is retried later, waiting longer after each failure, up to six hours. A source that refuses access is left alone for six hours, and a request to wait (Retry-After) is honoured.
• Only totals are kept: customers out and served, by county and by utility. No addresses, outage points, customer details or crew information are collected.

What the numbers mean

Figures are customers (meters) without power, as each utility reports them. Utilities without a public map, and outages a utility does not place in a county, are missing or counted only at the state level, so every figure is a floor. A utility that fails to report keeps its last reading for up to an hour, marked as previous. Readings are kept, and become the record for recent outages until the next annual EAGLE-I release covers them.

This site is not affiliated with any utility or agency. For your own outage, and when power should be back, use your utility's map: it is the official source.

Accuracy checks on the latest reading

Every reading is checked against itself and against the other sources. Nothing is changed by these checks; they show where to be careful.
