Green Bonds

Green bonds are bonds whose proceeds are used for “green” or environmentally beneficial projects. Alliant Energy is using green bonds to finance affordable renewable energy projects for our customers.

Our clean energy vision

Alliant Energy is part of a worldwide movement toward cleaner energy, carbon reduction and sustainability. We are transitioning our energy to a cleaner mix and expanding renewable resources.

In 2020, we announced an aspirational goal to achieve net-zero carbon dioxide (CO2) emissions from the electricity we generate by 2050. This builds upon our Clean Energy goals to eliminate all existing coal from our energy mix by 2040 and reduce CO2 emissions by 50% and water supply needs for fossil-fuel generation by 75% by 2030 from 2005 levels.

Green bond issuances for renewable projects

We invested an amount equal to the net proceeds from the sale of these bonds for wind and solar energy generation projects owned and operated by our Iowa energy company. 

In April 2019, Alliant Energy’s Iowa energy company, IPL, completed the issuance of $300 million 3.60% green bonds due 2029. We invested an amount equal to the net proceeds from the sale of these bonds for wind generation projects owned and operated by IPL.

In September 2019, Alliant Energy’s Iowa energy company, IPL, completed the issuance of $300 million 3.50% green bonds due 2049. We invested an amount equal to the net proceeds from the sale of these bonds for wind generation projects  owned and operated by IPL.

In September 2021, Alliant Energy’s Wisconsin company, WPL, completed the issuance of $300 million 1.95% green bonds due 2031. WPL intends to use the net proceeds from the sale of these bonds for construction and development of the Kossuth wind project and solar generation projects owned and operated by WPL.
