With Alliant Energy's Second Nature™ renewable energy program, your company can support the growth of earth-friendly “green power” created by wind, solar and biomass.

To be eligible, your business must be a farm, small business or commercial/industrial electric customer of Alliant Energy in Iowa, Minnesota or Wisconsin.

Your monthly contribution will be added as a non-metered addition to your Alliant Energy bill each month; your participation will begin with your next billing cycle.

As a thank-you for enrolling, you’ll receive a Second Nature gift: an antimicrobial telephone pad.

Enroll in Second Nature online through Your Account

Please note that enrollment may take up to eight weeks, depending on when your billing cycle begins and ends. Any changes to your participation become effective with the next practicable billing cycle.
