Homegrown, clean and cost-effective energy

The energy we deliver to customers includes wind energy from locations across Iowa, southern Minnesota and Wisconsin.

By the end of 2020, we are planning to add up to 1,200 megawatts of additional wind generation for our customers.

This added wind energy adds diversity to our energy mix, allowing us to deliver safe, reliable and affordable energy to customers.

Because wind energy is clean, it will help us meet our goal to reduce carbon dioxide emissions 40% from 2005 levels by the year 2030 across our entire service territory.

The many benefits of wind energy

  • Wind is a clean source of energy and a key part of our balanced energy mix.
  • Wind farms provide a significant economic value to our customers and communities. 

    • For example, adding more wind farms creates good-paying construction jobs and benefits supporting industries.
    • Landowners benefit through lease payments and additional roads to access farm fields.
    • Local communities and states benefit from increased tax dollars. 
  • Wind has no associated fuel expenses, which helps provide cost stability to customers.
  • Wind energy is competitive with other sources of energy. Some of the reasons for this include better technology and tax benefits. For example:
    • Improvements in technology have increased the amount of energy each turbine can generate.
    • Turbines and construction costs continue to decrease as the wind market continues to grow.

How we use wind energy

Owned and operated wind farms

We own and operate four wind farms across Iowa, Wisconsin and Minnesota.

On August 3, 2017, we announced plans to add up to 500 megawatts of additional wind generation to Iowa. 

This is in addition to a similar 500-megawatt expansion we announced and received approval for in 2016. Combined, these two projects would add 1,000 megawatts of wind generation to Iowa. That’s enough energy to power around 430,000 homes each year.

Learn about how these projects will deliver clean and affordable energy to customers, enhance our environmental stewardship and drive economic growth.

Purchased wind energy

We purchase wind energy from wind farms across Iowa, southern Minnesota and Wisconsin. On an average year, we purchase more than 500 megawatts of wind energy through long-term contracts.
