About Zion Energy Center Zion Illinois
Facility Overview
The Zion Energy Center sits in Zion, Illinois — a Lake County municipality on Lake Michigan’s western shore near the Wisconsin border. It is a natural gas-fired power generation facility rated at approximately 199 megawatts (MW).
Facility Facts:
- Current Operator: Zion Energy LLC (100% ownership interest)
- Parent Company: Constellation Energy Corp
- Operational History: Reportedly operating since approximately 2002
- Type: Natural gas-fired generation — not coal-fired or nuclear
- Regional Role: Mid-scale industrial facility serving the Northern Illinois grid
Geographic and Industrial Context
Zion lies within a heavily industrialized Lake Michigan corridor. Workers in this region often moved between multiple industrial sites throughout their careers, potentially accumulating asbestos exposure at several locations. That pattern of multi-site employment is equally common among Missouri and Illinois workers who traveled the Mississippi River industrial corridor — one of the most asbestos-intensive industrial zones in the Midwest. Facilities along and adjacent to this corridor include:
- Labadie Energy Center — Franklin County, Missouri (Ameren UE coal-fired plant on the Missouri River)
- Portage des Sioux Power Plant — St. Charles County, Missouri (Ameren UE, at the confluence of the Missouri and Mississippi Rivers)
- Sioux Energy Center — St. Charles County, Missouri
- Rush Island Energy Center — Festus, Missouri
- Granite City Steel / U.S. Steel — Granite City, Illinois (directly across the Mississippi from north St. Louis)
- Laclede Steel — Alton, Illinois
- Shell Oil / Roxana Refinery and Clark Refinery — Wood River, Illinois
- Monsanto Chemical — Sauget, Illinois and Creve Coeur/North St. Louis, Missouri (one of the most heavily litigated industrial sites in Missouri asbestos history)
- Alton Box Board — Alton, Illinois
- The decommissioned Zion Nuclear Power Station
- Chemical processing plants and pipeline infrastructure throughout the corridor
Union members affiliated with Heat and Frost Insulators Local 1 (St. Louis), Boilermakers Local 27 (St. Louis), Plumbers and Pipefitters UA Local 562 (St. Louis — the largest pipefitter local in Missouri), and Plumbers and Pipefitters UA Local 268 (Kansas City) worked across these sites throughout their careers. That multi-site exposure history matters in litigation — it broadens the pool of liable defendants, strengthens exposure timelines, and supports asbestos lawsuit Missouri claims in both Missouri and Illinois courts simultaneously.
Missouri union workers with multi-site exposure histories must act now. Pending Missouri legislation — HB1649 — would impose new trust fund disclosure requirements for claims filed after August 28, 2026. That date is approaching fast. A qualified asbestos attorney can help you file before the rules change.
Natural Gas Generation and Asbestos Risk
Zion runs on natural gas, not coal, unlike coal-fired Ameren UE facilities such as Labadie Energy Center, Portage des Sioux Power Plant, Sioux Energy Center, and Rush Island Energy Center along the Missouri and Mississippi Rivers. That distinction does not eliminate asbestos risk. Natural gas facilities incorporate industrial systems that may have used asbestos-containing materials throughout their construction and operation, including:
- High-temperature combustion turbines
- Steam generation and distribution systems
- Heat recovery steam generators (HRSGs)
- High-pressure pipe networks
- Boiler systems and pressure vessels
- Electrical switchgear and control systems
- Mechanical insulation systems
General Equipment at Zion Energy Center Zion Illinois
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 Illinois Environmental Protection Agency (Illinois 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 Illinois 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
Illinois law gives mesothelioma and asbestos-disease claimants 2 years from the date of medical diagnosis to file a personal-injury lawsuit (735 ILCS 5/13-202). For wrongful-death claims after an asbestos-related death, the filing window is 2 years from the date of death (740 ILCS 180/2). 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 Illinois 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.
