About Greenwood (MI) Power Station
Workers who built, operated, and maintained the Greenwood Energy Center in Avoca, Michigan may have been exposed to asbestos-containing materials across decades of construction, operation, and repair work. Today, former employees and contractors at this facility are being diagnosed with mesothelioma, asbestosis, and lung cancer. You have legal rights. You may be entitled to substantial compensation through an asbestos lawsuit or trust fund claim.
Many workers from the Mississippi River industrial corridor — including those who traveled between Michigan facilities and Missouri and Illinois job sites throughout their careers — face asbestos-related disease diagnoses decades after their last exposure. This page explains what happened at this facility, who faced the greatest risk, and what legal options remain available to you right now.
Michigan workers especially: the 2026 legislative threat described above is real and advancing. If you have received a diagnosis, call today — not next month, not after the holidays. Today.
The Greenwood Energy Center — also known as Greenwood Power Station — sits in Avoca, Michigan, in St. Clair County along Lake Huron. DTE Energy (formerly Detroit Edison) operates this conventional thermal generating station, which has supplied electricity to Michigan residential, commercial, and industrial customers for decades.
Why Power Plants Contained So Much Asbestos
Power plants built between the 1930s and 1970s ran on steam. That meant managing temperatures exceeding 1,000°F in boilers and turbines, pressures of hundreds of pounds per square inch in piping systems, and constant thermal cycling across every mechanical component. Asbestos-containing materials solved those engineering problems reliably and cheaply.
Manufacturers including, gaskets and packing, and supplied asbestos-containing insulation, gaskets, packing, refractory cements, and fireproofing to power stations across the country — including facilities like Greenwood and comparable stations along the Mississippi River industrial corridor such as AmerenUE’s Labadie Energy Center and Portage des Sioux Power Station in Missouri. Asbestos resisted fire, insulated against heat, withstood chemical exposure from steam and condensation, and held up mechanically under the most punishing industrial conditions.
Workers were not warned. By the time EPA and OSHA began regulating asbestos in the 1970s and 1980s, workers at facilities like Greenwood had already spent years or decades breathing asbestos fibers — without protective equipment, without medical monitoring, and without any notice of the hazard.
Asbestos causes mesothelioma, asbestosis, and lung cancer. These diseases typically appear 20 to 50 years after exposure. A worker insulating pipes at Greenwood in 1965 may be receiving a mesothelioma diagnosis today. If you’re facing that diagnosis now, an experienced Michigan asbestos attorney can help you understand your options — and time matters.
General Equipment at Greenwood (MI) Power Station
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 Michigan EGLE (Environment, Great Lakes & Energy) (Michigan EGLE) 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 Michigan EGLE 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.

The materials documented above (and similar asbestos-containing materials commonly encountered in records of this type) appear in the AsbestosIndex catalog with historical manufacturer and trust-fund information. Click a category to view manufacturers historically associated with that material:
Critical Filing Deadline & Next Steps
Michigan law gives mesothelioma and asbestos-disease claimants 3 years from the date of medical diagnosis to file a personal-injury lawsuit (MCL § 600.5805(13)). For wrongful-death claims after an asbestos-related death, the filing window is 3 years from the date of death (MCL § 600.5852). 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 Michigan 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.
