What Happened at Petersburg Generating Station: Facility Overview and Asbestos Exposure History
The Plant’s Role in Indiana’s Energy Infrastructure — and Its Connection to Indiana workers
Petersburg Generating Station is a coal-fired power facility in Pike County, along the White River near Petersburg in southwestern Indiana. For more than fifty years it supplied electrical generation to central Indiana. Over that same period, workers there — including many tradespeople dispatched from Missouri and Illinois union halls along the Mississippi River industrial corridor — may have been exposed to asbestos-containing materials throughout virtually every building, system, and maintenance activity on site.
Petersburg sits within the broader mid-American industrial region that encompasses the Mississippi River corridor stretching from the Quad Cities southward through St. Louis and into the Missouri Bootheel. Contractors, subcontractors, and union craftspeople from Missouri and Illinois regularly traveled to Indiana power generation and industrial facilities for construction and maintenance work during the peak demand periods of the 1960s through the 1980s. Workers dispatched from St. Louis-area locals — including Heat and Frost Insulators Local 1, Plumbers and Pipefitters UA Local 562, and Boilermakers Local 27 — may have spent time at Petersburg and returned to Missouri or Illinois, where they continue to reside and where legal claims may be filed.
The Mississippi River industrial corridor — running through major Missouri facilities including Labadie Power Plant (Franklin County), Portage des Sioux Power Plant (St. Charles County), and Monsanto chemical manufacturing sites, and across the river to Granite City Steel in Madison County, Illinois — drew from the same pool of skilled tradespeople who built and maintained Petersburg. Many of these workers spent portions of their careers at Missouri and Illinois facilities and portions at out-of-state plants like Petersburg, creating overlapping exposure histories that Missouri and Illinois courts are well-equipped to adjudicate.
Indiana residents diagnosed with mesothelioma or asbestosis today face a real and immediate threat to their legal rights.
Ownership and Operational Timeline
- Original operator: Indianapolis Power & Light Company (IPL)
- Current operator: AES Indiana (formerly AES Indiana Power), a subsidiary of AES Corporation
- Key acquisition: IPALCO Enterprises, IPL’s parent company, was acquired by AES Corporation in 2001
Unit Construction Phases and Asbestos Risk Periods
Petersburg was built in four separate expansion phases. Each phase created a distinct period of intensive construction-era asbestos-containing material exposure:
| Unit | Alleged Online Date | Critical Asbestos Exposure Period |
|---|---|---|
| Unit 1 | 1967 | 1965–1967 construction phase |
| Unit 2 | 1969 | 1967–1969 construction phase |
| Unit 3 | 1973 | 1970–1973 construction phase |
| Unit 4 | 1986 | 1984–1986 construction phase |
Units 1 through 3 came online during the late 1960s and early 1970s, when asbestos-containing materials were used across American heavy industry without meaningful legal restriction. Unit 4 was constructed in the mid-1980s — after decades of suppressed scientific evidence linking asbestos to fatal disease had already surfaced in litigation — yet asbestos-containing materials remained legal and in common use at power plants throughout that period.
Petersburg has employed hundreds — potentially thousands — of workers directly and through contractors over its operational history: construction workers, insulators, pipefitters, boilermakers, electricians, millwrights, and other specialized tradespeople. Many may have worked with or near asbestos-containing materials throughout the facility’s construction and long operational life. Missouri and Illinois residents who traveled to Petersburg for work retain full legal rights to pursue asbestos claims in their home-state courts or in the plaintiff-favorable venues of Lake County Superior Court, Madison County, Illinois, and St. Clair County, Illinois.
Time is the critical variable. Indiana’s 2-year asbestos statute of limitations runs from diagnosis — not from exposure at Petersburg. But
Why Asbestos-Containing Materials Were Embedded in Power Plant Operations: The Engineering Problem and Industry Solution
The Extreme Conditions Coal-Fired Power Plants Require
Coal-fired power generation produces some of the most demanding thermal, mechanical, and pressure conditions in industrial America:
- Steam temperatures in turbine systems exceed 1,000°F (538°C)
- High-pressure systems operate at 3,500+ PSI
- Miles of piping carry superheated steam while maintaining system efficiency
- Turbine casings, valve bodies, and expansion joints endure continuous thermal cycling
- Electrical systems require fire-resistant insulation capable of surviving arc flash and sustained extreme heat
These same conditions existed at Missouri River and Mississippi River corridor power plants — including Labadie and Portage des Sioux in Missouri and the power generation facilities serving Granite City Steel and Monsanto operations across the river in Illinois — where many of the same tradespeople who later traveled to Petersburg may have first encountered asbestos-containing materials in their careers.
Why Asbestos-Containing Materials Were Specified for Petersburg
Manufacturers including Johns-Manville, Owens-Illinois, Armstrong World Industries, Crane Co., and Combustion Engineering supplied extensive asbestos-containing product lines to American utilities. Their products were specified because they solved the above performance requirements simultaneously:
- Chrysotile and amphibole asbestos fibers withstand temperatures exceeding 1,000°F
- Asbestos fibers are stronger than steel by weight
- Asbestos resists acids, alkalis, solvents, and corrosive environments
- Low thermal conductivity maximized equipment efficiency and reduced fuel costs
- Asbestos-containing materials provided inherent fireproofing at low incremental cost
For utility companies building power plants in the 1960s, 1970s, and 1980s, specifying asbestos-containing products was standard engineering practice. Litigation evidence has established that asbestos manufacturers — including Johns-Manville and Owens-Illinois — suppressed internal research proving that asbestos fiber inhalation causes fatal disease. Whether utility companies knew of that suppression or deliberately avoided it remains a contested fact pattern in individual cases. Indiana and Illinois courts have extensive experience evaluating these product liability theories, and Lake County Superior Court in particular has a well-developed body of asbestos case law governing multi-state exposure claims.
**For Indiana workers who may have been exposed to asbestos-containing materials at Petersburg and at Indiana facilities during the same career, every day of delay in consulting an attorney is a day closer to the August 28, 2026
The Asbestos-Containing Material Environment at Petersburg
A coal-fired generating station of Petersburg’s era was not a building with isolated pockets of asbestos insulation. It was an environment where asbestos-containing materials were reportedly present in nearly every system:
| Facility Area | Asbestos-Containing Materials Allegedly Present |
|---|---|
| Boiler building | Thermal insulation on boiler surfaces, piping, fittings, and exterior ductwork; Johns-Manville and Owens-Illinois pipe insulation reportedly specified; spray-applied fireproofing |
| Turbine hall | Steam line insulation, turbine casing insulation, gaskets, valve packing, and electrical components; Crane Co. and Garlock gaskets and packings allegedly used |
| Control/electrical rooms | Switchgear, electrical panels, cable trays with fire-resistant materials and cable insulation; Armstrong electrical components allegedly present |
| Coal handling system | Conveyor components, transfer equipment, gaskets, and seals; Eagle-Picher sealing materials reportedly specified |
| Condensate/feedwater systems | Underground and above-grade pipe insulation, fitting insulation, valve gaskets; Johns-Manville products allegedly present |
| Air handling/HVAC | Ductwork insulation, pipe insulation, valve components; Georgia-Pacific and Celotex materials reportedly used |
| Valve stations and branch lines | Flanged and threaded valve assemblies with asbestos-containing gaskets and packing materials, reportedly from multiple manufacturers |
| Structural/flooring | Armstrong floor tile and adhesives, ceiling materials, and spray-applied fireproofing on structural steel — all allegedly containing asbestos |
Workers at Petersburg did not need to handle asbestos-containing materials directly to be at risk. Disturbing insulation during maintenance, cutting pipe, drilling through walls, working in enclosed mechanical spaces while insulators worked nearby, or simply performing daily tasks in areas where asbestos-containing materials were present and deteriorating — all of these activities may have generated dangerous fiber concentrations. This is the mechanism that drives mesothelioma diagnoses forty years after exposure: no safe level of asbestos fiber inhalation exists, and disease can result from relatively brief exposure events.
Workers and Trades at Highest Risk
Not every worker at Petersburg faced the same level of risk. The trades and job categories with the most intense alleged asbestos-containing material contact include:
Insulators and Pipe Coverers
Thermal insulators — often called “asbestos workers” in union classifications of the era — worked directly with asbestos-containing pipe covering, block insulation, and thermal blankets. They cut, shaped, mixed, and applied products containing up to 85% asbestos by weight. No trade
