Our Sustainable Developments

We power lives through our energy solutions and by making a difference in the communities we serve.

Supporting the United Nations
Sustainable Development Goals

The United Nations has adopted a plan for achieving a better future, called “Agenda 2030.” The goal for the United Nations is to end extreme poverty, fight inequality and injustice, and protect our planet. In this plan, there are 17 Sustainable Development Goals (SDGs).

Providing Affordable and Clean Energy (SDG7) for our customers is the foundation of our company’s long-term strategy. Our Corporate Sustainability Report shares how our actions align with SDG7 and many other SDGs to support a better and more sustainable future. We’re excited to work with our stakeholders on the SDGs toward a path to success.

Grow, optimize, and transform

Wind expansion going strong

We are in the process of adding another 680 megawatts of wind to our energy mix between late 2019 and the end of 2020. In March 2019, we put into service 470 megawatts of wind energy for our Iowa customers with the completion of our English Farms and Upland Prairie wind farms. This followed a 2018 purchase of a 59-megawatt ownership interest in the Forward Wind Energy Center to serve our Wisconsin customers.

Wind advances local growth

Our investments in wind energy help drive economic growth in local communities and enhance our environmental stewardship. From 2016 through 2020, Alliant Energy is investing more than $2 billion in wind generation facilities.

When combining our company’s existing wind farms with those we are building and developing, counties with wind projects will share an estimated average of $18 million a year in tax payments and utility-shared revenues by 2028.

Over 40 years, property taxes and utility-shared revenues to participating counties will total an estimated $670 million. These wind farms will also pay more than $6 million a year in payments to landowners.

Each facility we are building will create 300 new construction jobs, on average.

More solar underway

We currently have four solar facilities in service and plan to expand this as part of our clean energy transition. Future projects include solar gardens adjacent to our newest natural gas-fired generating stations in Marshalltown, Iowa, and near Beloit, Wisconsin.

Downtown Dubuque Solar Garden features an educational display to teach visitors about clean energy technology.

Goats remove invasive plants

A hired herd of goats recently made a second snacking stop at Alliant Energy’s energy campus near Beloit, Wisconsin. The goat workers ate invasive plants near the Rock River, where using equipment would be a challenge and pesticides could impact the water.

The EnvisionTM framework measures sustainable efforts using a scorecard and verification process, which then applies credits/points using five key categories.

Building sustainable infrastructure

The Envision system rates the sustainability of infrastructure projects across the full range of environmental, social and economic impacts. The Platinum award is the highest attainable Envision recognition level.

  • In 2017, our Marshalltown Generating Station in Iowa received Platinum recognition, the first facility in the state to earn an Envision sustainable infrastructure award.
  • In March 2018, our 6.2-megawatt Dubuque Solar site was the first solar project in the nation to receive Platinum recognition.
  • In 2019, the Upland Prairie and English Wind Farms also received recognition for Platinum level of achievement.

We are pursuing Envision certification for our West Riverside Energy Center under construction near Beloit, Wisconsin.

We're going underground

More than 20% of our electric lines are now underground rather than overhead. We plan to install most of our new electric lines underground as well as those that need replacement or upgrade. The cost of “undergrounding” has come down significantly. When considering the full life cycle cost of burying lines versus putting them overhead, the cost is about the same.

Burying lines transforms alley

Alliant Energy cooperated with a group in Marion, Iowa, that worked to transform an alleyway. Through removing the overhead power lines and putting them underground, the area became a usable and attractive public gathering space that showcases local artwork.

Wisconsin Clean Cities honors us for sustainable transportation

Wisconsin Clean Cities, a nonprofit coalition focused on promoting cleaner energy for transportation in Wisconsin, named Alliant Energy a Sustainable Transportation Champion for our use of clean fuels and technologies. The award was given in December 2018 at the group’s 24th annual Stakeholder Meeting held in Milwaukee.

In May 2019, we partnered with Wisconsin Clean Cities and the City of Madison for our first-ever Transportation and Innovation Expo. More than 300 people attended to learn about electrification and sustainable transportation technologies.

Electricity fuels business transport

An Iowa dairy business discusses the advantages of electric forklifts that they purchased with the help of rebates from Alliant Energy. Diesel idling emissions and fuel costs can be reduced by using electricity to cool or heat semitrailers that transport perishable products.

Level 3 fast-charging station introduced

In 2018, Alliant Energy provided rebates and was a consultant for an electric vehicle (EV) charging station project in Burlington, Iowa. The project, located at PZAZZ! Entertainment Complex, features Level 2 charging stations and a Level 3 fast-charging station. The Level 3 DC fast-charging station was the first of its kind in Iowa that can provide power to any vehicle capable of accepting a fast charge.

Innovate, take action, and serve

Technology speeds gas inspection

A new natural gas leak detection vehicle combined with the creativity of Alliant Energy employees is making us all safer. Examining our company’s distribution system is now faster and more precise and maps results digitally.

Wisconsin flood response

Heavy rains lasting more than a week occurred from late August to early September of 2018 in our Wisconsin service area. Many communities in southern and southwest Wisconsin experienced significant flooding. Mass evacuations uprooted the lives of hundreds of our customers. With the high water levels causing safety concerns, natural gas service was shut off for thousands of customers.

We worked together with impacted communities to restore utility services safely and as quickly as possible. The Alliant Energy Foundation gave eight grants totaling $32,500 to various groups to help with food pantries, emergency supplies and shelters for the flood recovery efforts. This included a $7,500 Community Grant to the Red Cross Disaster Partners Program in Wisconsin. The Disaster Partners Program comes to the aid of communities and families when natural disasters, fires or other emergencies strike in the state.

Marshalltown tornado support

On July 19, 2018, a powerful EF-3 tornado with estimated winds of 136-165 mph hit Marshalltown, Iowa, causing significant damage. More than 10,000 Alliant Energy customers lost electric or gas service or both as a result of the storm, which created the largest gas emergency event in our company’s history.

Our crews got to work immediately to make the area safe for restoration. In a little more than a week, the number of customers remaining without service was reduced to 160. In total, 466 Alliant Energy employees and contractors traveled to Marshalltown to assist with the response.

In the week after the tornado, the Alliant Energy Foundation gave $10,000 to the American Red Cross and $15,000 to Marshalltown’s Mid-Iowa Community Action Inc. to help with recovery efforts and provide assistance to those impacted by the tornado.

We worked with the Iowa Department of Natural Resources to provide trees at reduced prices, replacing 126 that were destroyed by the tornado.

Legal assistance aids recovery

Our Legal team provided free legal services to residents recovering from the July 19 tornado that devastated Marshalltown. The pro bono clinic was available to low-income residents. These individuals can be particularly vulnerable to exploitation and fraud in the wake of a natural disaster. We advised on insurance policies, real estate contracts and contractor fraud issues. Bilingual employees helped translate for those who spoke Spanish as their first language.

Supporting emergency first responders

In December 2018, our attorneys volunteered to support the Wills for Heroes program event in Portage, Wisconsin. They produced wills and other estate planning documents at no charge for 13 first responders and their spouses.

Employees making a difference

Our employees are giving back where they live and work. Giving back and volunteering are how we live our values and use our Energy for Good. Our efforts focus on four key areas – Helping Families, Education, Environment and Public Safety.

Monitoring monarchs

Habitat loss is one of the reasons the monarch butterfly population has decreased significantly in recent years. The pollinator gardens at our Madison office support monarch habitat with milkweed plants that the butterfly relies on. In summer 2018, 20 employees from our Madison office volunteered to monitor for signs of monarch butterflies.

By the end of summer, the team looked at over 700 plants and found 49 eggs, six caterpillars and 28 butterflies. The data was shared with scientists at the University of Minnesota Monarch Larva Monitoring Project. Just before the monarch butterflies left for their migration to Mexico, employees tagged two butterflies through Monarch Watch.

Wind brings the world to Lake Winnebago

Our support of the World Ice and Snow Sailing Association Championship helped bring the event back to the U.S. for the first time since 2015. We have strong wind power roots in the Fond du Lac area, with our Cedar Ridge Wind Farm visible from the competition site on Lake Winnebago.

In early February 2019, competitors from Canada, Estonia, Finland, Germany, Sweden, Switzerland, the Russian Federation and the U.S. raced across the ice and snow. Our leadership in wind energy made our participation a natural fit for the event.
