About Conesville Power Plant | Conesville
What Was the Conesville Facility?
The Conesville Power Plant was operated by AEP Generation Resources, a subsidiary of American Electric Power, on the Muskingum River in Coshocton County, Ohio. For nearly 70 years it was one of Ohio’s largest coal-fired generating facilities, serving customers across the Midwest and mid-Atlantic. The facility drew contract labor from union halls stretching across the Mississippi River industrial corridor, including Missouri and Illinois.
Facility Timeline:
- Unit 1 — placed in service approximately 1957
- Unit 2 — placed in service approximately 1958
- Unit 3 — placed in service approximately 1960
- Unit 4 — placed in service approximately 1973
- Units 5 and 6 — added during the 1970s and 1980s
- Peak generating capacity: over 2,000 megawatts
- Permanent workforce: hundreds of workers at any given time
- Contract workers: thousands over the decades — insulators, pipefitters, boilermakers, electricians, painters, and laborers dispatched from Missouri and Illinois union halls
- Closure: 2020
Facility closure does not extinguish legal rights. Mesothelioma develops 20–50 years after initial asbestos exposure. Workers who left Conesville decades ago are filing successful claims today — including in Ohio and Illinois courts.
If you or a family member worked at the Conesville Power Plant in Ohio and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer, you may be entitled to substantial compensation. Workers and families have recovered millions of dollars by filing claims against asbestos manufacturers and facility operators through litigation, settlements, and asbestos trust fund claims.
A qualified mesothelioma lawyer in Ohio can evaluate your exposure history and help you understand your legal options — including pursuing claims in Ohio and Illinois courts if you lived or worked in those states. This guide covers the exposure history at Conesville, which trades faced the highest risk, your Ohio’s statute of limitations rights, and the steps to take now.
⚠️ URGENT: Ohio Filing Deadline Warning
Ohio’s statute of limitations for asbestos personal injury claims is 2 years from the date of diagnosis — not the date of exposure — under Ohio Rev. Code § 2305.10.
That window is under active legislative threat.
In 2026, **> Every month you wait narrows your options. Evidence ages. Witnesses become unavailable. Asbestos trust funds — which have already paid out billions to victims nationwide — continue to deplete over time.
If you or a family member has been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer, contact a Ohio asbestos attorney immediately. The cost of a consultation is zero. The cost of waiting may be everything.
This article is for informational purposes only and does not constitute legal advice. If you or a loved one may have been exposed to asbestos-containing materials at Conesville Power Plant and have since developed mesothelioma, asbestosis, or a related illness, consult a qualified asbestos litigation attorney in Ohio or Illinois immediately.
General Equipment at Conesville Power Plant | Conesville
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.
No Ohio EPA NESHAP abatement notifications have been identified for this facility in current public records. Per the framing above, absence of state-agency documentation should not be read as absence of asbestos — only as absence of a formal, regulated abatement event meeting reporting thresholds. Workers who recall encountering pipe insulation, block insulation, gaskets, or other asbestos-era construction materials at this facility may still have viable claims regardless of whether a state record exists.

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
Why Missouri and Illinois Workers Were at Midwest Power Plants
The Mississippi River industrial corridor — stretching from Metro East Illinois communities through St. Louis and northward — was one of the most heavily industrialized regions in America during the mid-twentieth century. Power plants, chemical facilities, steel mills, and manufacturing operations lined both banks of the river for hundreds of miles.
Workers from this corridor routinely traveled to major power generating projects across the Midwest, including AEP facilities in Ohio. Missouri and Illinois union halls dispatched skilled tradespeople — insulators, pipefitters, boilermakers, and electricians — to large generating facilities during planned outages and major construction projects.
Those workers may have been exposed to asbestos-containing materials at Conesville and returned home to Ohio and Illinois communities. That history creates asbestos exposure claims cognizable in Ohio courts — where an experienced Ohio asbestos attorney can file suit on your behalf.
Missouri Facilities with Similar Asbestos Exposure Profiles
Workers with exposure histories at both Conesville and the following facilities may have cumulative claims spanning multiple states and multiple defendants:
- AmerenMO Labadie Energy Center (Franklin County, Missouri) — one of the largest coal-fired plants in Missouri, where workers may have encountered asbestos-containing materials consistent with Conesville-era construction and insulation systems
- AmerenMO Portage des Sioux Power Plant (St. Charles County, Missouri) — a Mississippi River corridor facility with similar construction-era thermal insulation systems
- Monsanto Chemical / Solutia facilities along the St. Louis riverfront — major employers of Missouri insulators and pipefitters who may have been exposed to asbestos-containing materials during routine maintenance operations
- Granite City Steel (Madison County, Illinois) — a heavy industrial employer across the river from St. Louis, where workers may have been exposed to asbestos-containing materials during decades of steel production
A qualified asbestos attorney in Ohio can evaluate claims across all facilities where you worked.
