Did You Work at Edgewater Generating Station? You May Have Been Exposed to Asbestos-Containing Materials
The Edgewater Generating Station in Sheboygan, Wisconsin — operated by Wisconsin Power and Light Company (WP&L), now part of Alliant Energy — is a coal-fired power plant where hundreds of workers may have been exposed to asbestos-containing materials across more than seven decades of operation. Workers in construction, maintenance, operations, and contractor roles between the 1950s and 2020s may face health consequences with latency periods of 10, 20, or even 40 years or more.
Wisconsin and Illinois workers were not insulated from these risks. Contractor trades traveling from Wisconsin and Illinois to Wisconsin jobsites along the Mississippi River industrial corridor — insulators, pipefitters, boilermakers — may have carried asbestos-related hazards home with them. If you live in Wisconsin today and worked at Edgewater, you have legal rights enforceable in Milwaukee County Circuit Courts, among the most active asbestos lawsuit venues in the country.
With pending legislation threatening to reshape the legal landscape for claims filed after August 28, 2026, the time to contact a Wisconsin mesothelioma lawyer is now.

The Edgewater Generating Station is a coal-fired electric generating facility on the western shore of Lake Michigan in Sheboygan, Wisconsin.
Facility Details:
- Address: 231 Pagel Road, Sheboygan, WI 53081
- Operator: Wisconsin Power and Light Co. (WP&L), now Alliant Energy
- Type: Coal-fired steam electric generating station
- Unit 4 Capacity: ~330 megawatts
- Unit 5 Capacity: ~380 megawatts
- Years of Operation: Early 1950s through 2022 (decommissioning ongoing)
- Workforce: Hundreds of direct employees plus an extensive contractor workforce
- Regulatory Agencies: EPA and Wisconsin DNR
Construction and Potential ACM Installation Phases
Asbestos-containing materials may have been installed during every construction and expansion phase at Edgewater:
- Unit 1: Early 1950s
- Units 2 & 3: Late 1950s–early 1960s
- Unit 4: Commissioned 1969
- Unit 5: Completed 1985
Each phase may have involved installation, disturbance, or removal of asbestos-containing products from manufacturers including Johns-Manville, Owens-Illinois, Owens Corning, Combustion Engineering, Armstrong World Industries, and W.R. Grace. Workers who built, operated, maintained, or are now involved in dismantling this facility over its 70-plus year lifespan may have been repeatedly exposed to asbestos-containing materials.
Why This Matters to Wisconsin residents
The Mississippi River industrial corridor — running north from St. Louis through Illinois — was a primary labor pipeline for major Midwest construction and maintenance projects, including power plants like Edgewater. Missouri-based tradespeople regularly traveled for plant outages and major construction jobs. Workers who spent the bulk of their careers at Missouri facilities such as Ameren’s Labadie Energy Center (Franklin County) or Portage des Sioux Power Station (St. Charles County) may have supplemented their work histories with Wisconsin jobsites — accumulating cumulative asbestos-containing material exposures across multiple states.
That multi-state exposure history is directly relevant to the legal claims available under Wisconsin law today.

Regulatory Context
Edgewater has been subject to National Emission Standards for Hazardous Air Pollutants (NESHAP) compliance requirements governing asbestos abatement during renovation and demolition. Those requirements exist precisely because asbestos-containing materials are known to be present in older industrial facilities of this type and vintage.
Why Asbestos-Containing Materials Were Standard in Power Plants
The Engineering Reality
Coal-fired steam generating stations operate under conditions that demanded specific performance from insulation and protective materials:
- Boilers running above 1,000°F
- High-pressure steam turbines operating at 750–1,050°F
- Steam pipes and headers carrying superheated steam under high pressure
- Feedwater heaters, condensers, and heat exchangers requiring thermal management throughout their operating lives
Why Nothing Else Was Used
Before the 1970s, no synthetic material matched asbestos-containing products across the combination of properties that power plant engineers required:
- Heat resistance above 1,000°F without structural degradation
- Tensile strength under sustained mechanical stress
- Flexibility to conform to pipes and equipment of irregular shapes
- Electrical non-conductivity for safe use around electrical systems
- Chemical resistance to steam, condensate, and industrial process environments
- Cost-effectiveness at the scale required for large generating stations
These properties made asbestos-containing materials the default specification in virtually every high-heat and high-friction application from the 1940s through the 1970s. Engineers were not cutting corners — they were using what the industry supplied as the standard solution.
Industry-Wide Specifications (1940s–1970s)
Specifying asbestos-containing materials in power plant construction was the engineering norm, not the exception. Utilities, architects, and manufacturers routinely incorporated products from Johns-Manville (including Kaylo pipe insulation and Thermobestos products), Owens-Illinois (including Aircell insulation board), Armstrong World Industries (including asbestos-containing floor tiles), and W.R. Grace into:
- Pipe and boiler insulation systems
- Turbine insulation blankets and coverings
- Gaskets and packing materials
- Floor and ceiling tiles
- Fireproofing sprays and coatings
- Electrical insulation components
- Protective clothing for workers in high-heat areas
Manufacturer Knowledge and Alleged Concealment
Major asbestos manufacturers — including Johns-Manville, Owens-Illinois, Owens Corning, Combustion Engineering, Armstrong World Industries, W.R. Grace, Garlock Sealing Technologies, Crane Co., and Georgia-Pacific — are alleged to have possessed internal scientific research demonstrating asbestos’s lethal health effects for decades before that information reached the workers using their products. Despite this alleged knowledge, these manufacturers reportedly continued marketing asbestos-containing products to the power industry without adequate health warnings until regulatory action forced change in the 1970s and 1980s. This alleged concealment is a central liability theory in asbestos lawsuits pursued in Missouri and Illinois courts — and it is why significant settlement and verdict money remains available to workers diagnosed today.
Timeline: Decades of Potential Asbestos-Containing Material Exposure
Phase 1: Original Construction (1950s–1960s) — Highest Exposure Risk
During construction of the earliest Edgewater units, asbestos-containing materials may have been present in essentially every aspect of power plant assembly. Workers in construction, insulation, and equipment installation during this phase may have been exposed to:
- Raw asbestos-containing pipe insulation applied to pipes, boilers, and steam lines — including Kaylo pipe wrap and Thermobestos insulation reportedly supplied by Johns-Manville
- Asbestos-containing joint compounds and cements used during equipment fitting and assembly — including products allegedly supplied by Combustion Engineering
- Asbestos-containing board and panels installed in control rooms and administrative areas — including products allegedly supplied by Armstrong World Industries
- Asbestos-containing floor tiles throughout the facility — including Gold Bond products from Armstrong and similar products from Georgia-Pacific
Freshly applied asbestos-containing materials release more airborne fibers than aged, intact materials. This construction phase likely represents the highest-exposure era at Edgewater.
Missouri and Illinois union members who worked at comparable facilities during the same era — including Labadie and Portage des Sioux power stations in Missouri, and Granite City Steel in Madison County, Illinois — experienced this same pattern of construction-era asbestos-containing material exposure. Workers who traveled between these facilities and Wisconsin jobsites during the 1950s and 1960s may have accumulated significant cumulative exposures.
If work at Edgewater during this period has now produced a diagnosis, Wisconsin’s 3-year statute of limitations is running from your diagnosis date — and
Phase 2: Expansion and Intensive Maintenance (1960s–1980s)
Construction of Unit 4 (1969) and Unit 5 (1985), combined with decades of routine maintenance and major overhauls, created ongoing asbestos-containing material exposure potential. During this period:
- Maintenance turnarounds may have required workers to remove and replace insulation from pipes, turbines, and boilers — generating concentrated airborne fiber releases in enclosed plant spaces
- Insulation contractors, including members of Heat and Frost Insulators Local 1 (St. Louis) who may have traveled to Wisconsin jobsites, were regularly brought in to reinsulate equipment after major overhauls
- Gasket and packing replacement on valves and flanges — including products allegedly supplied by Garlock Sealing Technologies and Crane Co. — may have released asbestos-containing fibers during removal and installation
- Boiler repairs and refractory work may have disturbed asbestos-containing fireproofing and refractory materials installed during original construction
- Bystander exposure was a real and documented risk: workers present in plant spaces when other trades disturbed asbestos-containing materials may have inhaled airborne fibers without ever performing hands-on insulation work themselves
