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 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.
Frequently asked questions
Customer sustainability goals and better renewable technology are driving the transition to renewable energy. And while coal generation used to be the least expensive energy source, it’s now among the most expensive.
Rather than investing hundreds of millions to maintain older, more expensive technology, we are investing in cleaner, less expensive renewables like solar. We are focusing on lowering costs, creating environmental benefits, meeting customer demand and being a good partner with the communities we serve.
The property is 265 acres. It's located along Lake Michigan at 3739 Lakeshore Drive in Sheboygan.
Through the state’s shared revenue program, the city of Sheboygan and Sheboygan County receive more than $1 million annually as a result of the generating station being located in the city. Those annual payments will continue even after Edgewater is retired.
Once the facility is decommissioned, the shared revenue payments will be phased out over a five-year period and the property will go on the local property tax rolls. After the five-year phased out period, the city and county will no longer receive shared revenue payments from the state.
We will continue to have our Sheboygan Operations Center in the city that maintains our energy services throughout the region. About 20 customer service representatives, line and engineering technicians, account managers, maintenance workers and administrative personnel work out of the building.
We are also planning to acquire and put into service a 150-megawatt solar garden in Sheboygan County by the end of 2022.
