Where this data comes from
Numbers on this page come from Ameren's public outage data — the same data behind its official outage map — collected on a rotating cycle (each utility typically refreshes within the hour; the card above shows exactly when these numbers were last collected). When the utility posts a restoration time we show it as the official estimate; our independent estimate is computed from the outage's own recovery trend, and our county-wide estimates are graded publicly. Coverage and level of detail vary by utility: some break out towns and neighborhoods, others publish only county or area totals.

Common questions
How do I report a power outage to Ameren?
Report outages and downed lines directly to Ameren through its official outage site or its outage phone line — crews are dispatched from customer reports. This page is an independent tracker, not affiliated with Ameren; never rely on it for emergencies. In a life-threatening situation, call 911.
Does Ameren give an estimated restoration time?
When Ameren posts an estimated restoration time for an outage, we show it as the official estimate. Alongside it we show our own independent estimate from the outage's live recovery trend — useful when the utility hasn't posted a time yet. Both appear side by side.
Why isn't my outage showing for Ameren?
A brand-new or single-customer outage may not appear in the utility's public data yet, and the level of detail varies — some Ameren data breaks out towns and neighborhoods, other sources publish county or area totals only. If your power is out and it isn't listed, report it to Ameren so it enters their system.
How accurate is the Ameren restoration estimate?
Our independent estimator is re-run after each completed county outage and checked against when the tracked outage was substantially restored (~90% of customers back); the results are on our accuracy page. Utility posted times are graded there too where they reach the national county outage data, and a utility is listed by name once enough of its outages are graded.
