About Stuart Generating Station | Aberdeen, OH | AES Ohio
Stuart Generating Station sits in Aberdeen, Ohio, along the Ohio River in Adams County. The plant operated as one of the largest coal-fired power generation facilities in Ohio, serving regional electricity demands for decades.
Construction and Operation Timeline:
- Unit 1 — Commercial operation began in 1970
- Unit 2 — Commercial operation began in 1971
- Unit 3 — Commercial operation began in 1972
- Unit 4 — Commercial operation began in 1974
The plant was named for Edwin J. Stuart, a longtime executive with Dayton Power and Light Company (DP&L), the original developer and operator.
A consortium of Ohio utility companies developed and originally owned the facility:
- Dayton Power and Light Company (DP&L) — primary operating partner and facility manager
- Columbus Southern Power Company — co-owner
- Ohio Power Company — co-owner
Ownership Changes:
- DP&L operated the facility as primary managing partner for many years
- AES Corporation subsequently acquired DP&L
- Operational control transferred to AES Ohio LLC, the current or most recent operating entity
- Coal operations were retired and decommissioned in recent years
Construction ran from the late 1960s through the mid-1970s — the peak period of industrial asbestos use in the United States. Every major power plant built during this era was constructed with asbestos-containing materials woven throughout its systems. Decommissioning and demolition work that followed created additional asbestos exposure risks for workers involved in abatement and remediation.
General Equipment at Stuart Generating Station | Aberdeen, OH | AES Ohio
The equipment below represents the systems and infrastructure documented or typically present at this facility during the era when asbestos-containing materials were specified in industrial construction. This is general facility-equipment reference — not a legal attribution of any specific product, manufacturer, or exposure event to this facility. Material-category and manufacturer information is addressed in the AsbestosIndex Product Crosswalk linked under the records table below.
Documented Asbestos Evidence
The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Ohio Environmental Protection Agency (Ohio EPA) was notified under federal NESHAP rules, the work was logged, and the asbestos-containing material was confirmed and removed under regulated conditions. These are not allegations or estimates — they are paper records tying documented asbestos-containing material to this specific site.

Who May Have Been Exposed at Stuart Generating Station | Aberdeen, OH | AES Ohio
Workers in skilled trades represented by Heat and Frost Insulators Local 1 (St. Louis, MO) and Plumbers and Pipefitters UA Local 562 (St. Louis, MO) — boilermakers, pipefitters, insulators, and electrical maintenance workers — may have faced especially high asbestos exposure risks. Heat and Frost Insulators Local 1 members — based in St. Louis and historically dispatched throughout Ohio, Southern Illinois, and the Ohio Valley — performing insulation work throughout the facility may have been at particularly high risk.
Virtually every major maintenance activity — replacing pipe insulation, cutting into boiler components, removing and replacing gaskets, rewiring electrical systems — reportedly had the potential to disturb asbestos-containing materials and release fibers directly into workers’ breathing zones. Members of Heat and Frost Insulators Local 1 (St. Louis) and UA Local 562 dispatched to Ohio Valley project work reportedly performed this type of hands-on, fiber-releasing work as core functions of their trade assignments.
Critical Filing Deadline & Next Steps
Ohio law gives mesothelioma and asbestos-disease claimants 2 years from the date of medical diagnosis to file a personal-injury lawsuit (ORC § 2305.10). For wrongful-death claims after an asbestos-related death, the filing window is 2 years from the date of death (ORC § 2125.02). The two deadlines run on separate tracks — preserving one does not extend the other.
The personal-injury clock runs from diagnosis, not from exposure. Mesothelioma latency is typically 20 to 50 years, so workers exposed in the 1950s–1980s are being diagnosed today.
Practical first steps
- Document what you remember. Pay stubs, W-2s, union cards, photographs, coworker names, and dates of employment. The WorkChain widget on this page can save a copy you can email yourself.
- Preserve medical records. Pathology reports, biopsy results, imaging, and pulmonary-function tests are central to both civil claims and trust-fund filings.
- Identify household members. Spouses who laundered work clothing and children of plant workers are eligible for secondary-exposure claims when diagnosed with an asbestos-related disease.
- Speak with an asbestos attorney with Ohio experience. The first conversation is free and confidential. Asbestos trust-fund claims and civil claims run on different tracks — both can be pursued in parallel.
Asbestos-Related Diseases
Asbestos fiber exposure can cause several specific diseases that typically appear decades after the original exposure. The latency period — the gap between exposure and diagnosis — usually runs 20 to 50 years. That's why workers exposed in the 1960s, 1970s, and 1980s are receiving diagnoses today.
Mesothelioma
A rare, aggressive cancer that affects the lining of the lungs (pleural mesothelioma), abdomen (peritoneal), or heart (pericardial). Mesothelioma is almost exclusively caused by asbestos exposure, which is why a mesothelioma diagnosis often points directly to historical workplace exposure. Average latency from first exposure to diagnosis is 30-50 years.
Asbestosis
A chronic, non-cancerous scarring of lung tissue caused by inhaled asbestos fibers. Asbestosis causes progressive shortness of breath, persistent cough, and reduced lung function. It does not improve with treatment, and it is a recognized basis for compensation under most trust schedules and civil claims.
Lung Cancer
Asbestos exposure significantly increases the risk of lung cancer, particularly when combined with a history of smoking. Asbestos-related lung cancer is compensable under the same trust schedules and civil claim avenues as mesothelioma.
Other Recognized Diseases
Pleural plaques, pleural thickening, laryngeal cancer, ovarian cancer, and certain gastrointestinal cancers are also recognized as asbestos-related under various trust schedules and case-law authorities, though eligibility and proof requirements vary by claim type.
If you have any of these diagnoses and you worked at this facility, lived with someone who did, or were exposed in any documented capacity, you may have a claim worth pursuing. Speak with an attorney before assuming you don't qualify.
Cross-State & Regional Corridor Workers
Tradespeople from the Missouri and Illinois side of the Mississippi River industrial corridor were routinely dispatched to large Ohio Valley power plants like Stuart. Missouri and Illinois residents diagnosed with asbestos-related diseases may hold viable claims arising from work performed at this facility. The same product lines from and allegedly distributed to Stuart Generating Station were also reportedly distributed to Missouri River corridor facilities including Labadie Energy Center and Portage des Sioux. A Local 1 insulator’s lifetime asbestos exposure record may span multiple states and multiple facilities. Workers who traveled the Mississippi River industrial corridor between Missouri, Illinois, and the Ohio Valley during construction and maintenance campaigns may have encountered asbestos-containing materials at multiple facilities.Data Sources
