Welcome to the Edgewater Generating Station public information and redevelopment website. As Alliant Energy continues planning for the facility’s retirement, we’re working with the Sheboygan community on what the future will look like for the site.

This website will keep our partners, customers, friends and neighbors in the Sheboygan area updated about the project and opportunities to have conversations and share ideas.

If you have a comment, suggestion or question, please submit your thoughts on our contact form.

We are proud of Edgewater and the generations of employees who have operated it for nearly a century.


In May 2020, we announced plans to retire the coal-fired Edgewater Generating Station in Sheboygan, Wisconsin by the end of 2022. Read more about this decision that furthers our goal of delivering cleaner, more cost-effective energy to customers.

As we transition from coal to cleaner energy, we will remain focused on caring for our customers and employees by creating new jobs and bringing new economic development opportunities to the community.

Our sustainable energy plan

The Clean Energy Blueprint is our roadmap for accelerating our transition to cleaner, renewable energy in Wisconsin - guiding our efforts to enhance the economic and environmental health of the communities we serve. This includes increasing our use of renewable resources and provides direction for the future of our coal-fired generation.

As we move forward with our Sustainable Energy Plan, Alliant Energy has set a Clean Energy Vision that includes an aspirational goal to reach net-zero carbon dioxide (CO2) emissions by 2050 for the electricity we generate. To support meeting that goal, while delivering cleaner, more cost-effective energy, we have also established a goal to eliminate all coal from our generation fleet by 2040.

For more information on how we are acting today – to meet our customers’ future energy needs tomorrow - please visit our Powering What’s Next website. For more details on our sustainability and responsibility actions, please read our Corporate Responsibility Report.

Site reuse planning process and redevelopment

The transition of the Edgewater Generating Station site into its new future is a multi-stage, multi-year process. The retirement and decommissioning of the facility will be coupled with the development of a site reuse plan. The reuse planning process will include opportunities for the public and other stakeholders to provide input in the early stages of analysis, during plan development and throughout the plan approval process.

Please stay connected throughout the planning process!

Edgewater history

Edgewater Generation Station went into service about 90 years ago, making it one the oldest continuously operating electric generating stations in Wisconsin. Over the years, the facility has included five coal-fired generating units. Units 1 – 4 have been retired, leaving the 414-megawatt Unit 5 as the only generator still in operation. Unit 5 went into operation in 1985.'

Edgewater environmental investments

Over its history, we have taken specific and significant actions to reduce the environmental impact of Edgewater. Our company strives for continuous improvement in our environmental performance. Recent examples include the addition of technology to reduce nitrogen oxides, sulfur dioxide, fine particulate, mercury and other air emissions. In addition, a new system was also added to expedite the closure of Edgewater’s coal ash ponds.
