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 2018, we announced a goal to eliminate all existing coal from our energy mix and cut carbon dioxide (CO2) emissions 80% by 2050 from 2005 levels from our fossil-fueled generation. This builds upon our goals to have renewables be over 30% of our energy mix by 2030, as well as reduce CO2 emissions by 40% and water supply needs from 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 of owned wind as well as expanding our solar power resources.

“We are transforming our energy fleet with an eye on customer cost, carbon reduction and cleaner power,” said Patricia Kampling, Chairman and CEO of Alliant Energy. "Proceeds from the green bonds will finance a portion of the wind and solar investments which are an integral part of this transformation.”

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 of green bonds. We are spending an amount equal to the net proceeds from the sale of these bonds for renewable energy generation projects that will be owned and operated by IPL. IPL is the eighth investment-grade energy company in the nation to sell green bonds.

Within one year of issuance, we will provide an update on our website regarding the allocation of the new proceeds of the bonds to renewable energy generation projects, including the key environmental features of such expenditures. To explore the projects these green bonds will finance, please visit our Iowa wind page and the Iowa section of our solar page.
