Our sustainable energy plan

We're acting for tomorrow


Our strategy focuses on meeting our customers’ future energy needs through a balanced resource portfolio. We are implementing our plans to deliver reliable service while leveraging a diverse mix of cost-competitive energy sources. We are also investing in our distribution infrastructure to make it smarter and adaptable to support evolving energy technologies as well as stronger and more resilient to changing climate conditions.

Successful execution of our strategy will enable us to achieve our Clean Energy Vision goals to reduce greenhouse gas emissions. We will continue to review and update our Sustainable Energy strategy and Clean Energy Vision, based on future economic developments, evolving energy technologies and emerging trends in the communities we serve.

Here are some of the ways we’re helping our customers and communities Power What’s Next:

Solar


Solar energy is clean, renewable and here to stay. What’s more, solar energy is simpler and less expensive to operate and maintain than traditional coal-powered generation. This translates to long-term economic value for customers and the communities we serve.

Our existing and planned solar projects will power hundreds of thousands of homes across Wisconsin. In addition, we’re bringing Community Solar projects to light later this year.

Wind


Homegrown, clean and low-cost, wind is well-established in the Midwest. Alliant Energy operates and purchases power from wind farms across Iowa, Wisconsin and Minnesota.

These wind farm investments provide a variety of revenue streams to local communities and also create well-paying construction jobs.

Hydropower


For nearly a century, we’ve been delivering customers electricity from our hydroelectric dams. We also have purchased power agreements with other hydroelectric facilities across Wisconsin and Iowa, many of which we previously owned, that add to our renewable energy mix.

Electrification


Electric vehicles are increasingly popular and sensible. By powering cars, trucks and more with energy according to our Clean Energy Blueprint, we can lower fuel costs and emissions. We are excited to be on the leading edge of electrification efforts in our communities. By 2030, 100 percent of our active light-duty fleet will be battery electric or plug-in electric vehicles.

Battery storage


Renewable energy sources like solar panels and wind turbines cause ebbs and flows on the energy grid as their production fluctuates. Battery storage units smooth out these fluctuations to meet the needs of customers and avoid costly energy grid rebuilds. One battery storage unit we installed in Iowa can store enough energy to power 650 nearby homes for four hours!

We currently have these types of battery storage systems in place. We are gathering operational data for how to most effectively use the stored power and how to cost-effectively replicate them in other places throughout our service area.

Fiber optic cable


Operating the grid of the future will require more data – and fiber will help us serve customers through new and innovative ways. We are installing fiber optic cabling across our service area to create better, faster and stronger digital highways between our critical facilities.
