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 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.

Investing in renewable energy

Alliant Energy plans to spend more than $2 billion on new renewable energy sources from 2016 through 2020. Planned new resource additions include over 1,100 megawatts (MW) of owned wind and 1,000 MW of owned solar power resources.  

Green bond issuances for renewable projects

In September 2018, Alliant Energy’s Iowa energy company, Interstate Power & Light Company (IPL), completed the issuance of $500 million 4.10% green bonds due 2028. We are spending an amount equal to the net proceeds from the sale of these bonds for wind and solar energy generation projects that will be owned and operated by IPL. 

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