Where this data comes from
Numbers on this page come from Alliant Energy'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 graded publicly. Coverage and level of detail vary by utility: some break out towns and neighborhoods, others publish only county or area totals.
Not affiliated with Alliant Energy. Report outages and downed lines to the utility directly via its official outage site ↗ — never rely on this page for emergencies.
Common questions
How do I report a power outage to Alliant Energy?
Report outages and downed lines directly to Alliant Energy 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 Alliant Energy; never rely on it for emergencies. In a life-threatening situation, call 911.
Does Alliant Energy give an estimated restoration time?
When Alliant Energy 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 Alliant Energy?
A brand-new or single-customer outage may not appear in the utility's public data yet, and the level of detail varies — some Alliant Energy 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 Alliant Energy so it enters their system.
How accurate is the Alliant Energy restoration estimate?
Our independent estimates are graded against when the tracked outage was substantially restored (~90% of customers back), published on our accuracy page. Alliant Energy's own posted restoration times are graded there too, so you can compare them.
