    FAQ

    Questions

    How much does Alliant Energy Smart Hours (Iowa) pay?

    $25 to $100, depending on what you install. The table under How much you get lists each amount.

    Do I need to be a Interstate Power and Light customer?

    Yes. It’s only for homes in Interstate Power and Light customers, Iowa. See Do I qualify for the details.

    Is it still available?

    Yes. It was open when we last checked, on October 28, 2026.

    Can I override a Smart Hours event?

    Yes. You can change your thermostat or device settings during an event, but that opts you out of the event, and opting out too often can cost you the seasonal reward.

    Will Alliant change my settings on normal days?

    No. Alliant contacts you a day before each event and never adjusts your settings on non-event days.
