As of October 2026, there is no open Duke Energy settlement, no claim form, no deadline and no checks being mailed to customers. Two proposed class actions are still alive: a coal ash contamination suit in Mooresville, North Carolina, and a wage-fixing suit by nuclear workers in Maryland federal court. The 2024 data breach suits ended in private settlements in 2025 with terms that were not disclosed. The well-known Ohio settlement checks date back to 2016.

What the Duke Energy Lawsuits Are About
“Duke Energy lawsuit” covers several unrelated cases. The two that matter for ordinary people today:
Mooresville coal ash (customers and property owners). The lawsuit alleges Duke Energy disposed of and sold coal ash for use as structural fill, contaminating soil, groundwater and Lake Norman, failed to clean it up, and hurt property values. Claims include negligence, gross negligence, private nuisance and trespass.
Nuclear pay (workers). The lawsuit alleges the U.S. nuclear power industry, including Duke Energy, conspired to suppress pay by exchanging salary information since 2003, in violation of Section 1 of the Sherman Act. It seeks treble damages for current and former nuclear workers.
Duke Energy disputes both cases. Neither has been proven.
Case Details
Coal ash: filed December 20, 2024 by 15 plaintiffs in Iredell County, North Carolina (state court) against Duke Energy, Duke Energy Carolinas and Duke Energy Progress on behalf of a putative class.
Nuclear pay: Dorrell v. Constellation Energy Corp., No. 1:25-cv-02251, U.S. District Court for the District of Maryland, Judge Adam B. Abelson. Filed July 11, 2025. Duke Energy Carolinas and Duke Energy Business Services were added as defendants on November 5, 2025. The court’s August 5, 2026 opinion is public.
Data breach: Saunders v. Duke Energy Carolinas, No. 3:24-cv-01074, U.S. District Court for the Western District of North Carolina, filed in December 2024 over a May 2024 incident.
Status: Two Cases Pending, Nothing to Claim
Coal ash: on February 4, 2026, the court refused to throw out most of the case (a strict liability claim was dismissed earlier). In its quarterly report filed August 4, 2026, Duke Energy said a scheduling order had been entered and the parties were evaluating an early mediation. Mediation is not a settlement.
Nuclear pay: on August 5, 2026, Judge Abelson dismissed the amended complaint as untimely, without prejudice, and gave the workers 45 days to ask permission to amend. Law360 reported on September 22, 2026 that the workers had asked to amend. We found no ruling on that request as of October 2026.
Data breach: Saunders dropped all claims in a joint filing reported May 30, 2025, after a private deal with undisclosed terms. Duke Energy also settled six other breach cases. Terms were not disclosed, and we found no public claim form or customer notice.

Who Could Be Affected
Coal ash: the proposed class concerns people in the Mooresville, North Carolina area tied to the alleged contamination. No class has been certified, and you cannot sign up.
Nuclear pay: the proposed class is current and former employees in the U.S. nuclear power industry, not Duke Energy customers.
Data breach: customers notified about the May 2024 incident. That litigation is over. Duke Energy has said no customer’s personally identifiable information, as defined by state law, was exposed.

Duke Energy Settlement Checks: What Was Paid and What Is Not
Duke energy settlement checks update: the checks people remember came from Williams v. Duke Energy in the Southern District of Ohio, an $81 million settlement of a 2008 lawsuit alleging Duke gave rebates to large industrial customers that ordinary ratepayers never got. Up to $25 million went to Duke Energy Ohio residential customers and up to $25 million to non-residential customers who were customers between January 1, 2005 and December 31, 2008, with $8 million for energy programs. Final approval came in April 2016. More than 200,000 customers filed forms, and WCPO reported checks of up to $200 per homeowner after repeated delays. Kentucky and Indiana customers were not included. The claim filing period ended years ago.
For the pending cases, no court has valued any claim.
How cases like this one end
Our copy of the federal courts’ own case database covers 6,659 antitrust casesclosed in U.S. federal district courts between 2015 and 2025, 37.3% of them filed as class actions:
- 19.7% ended in a settlement recorded by the court. Another 14.4% were dismissed voluntarily, which often follows a private settlement — so the real settlement share sits between 19.7% and 34.1%.
- 11.6% were decided on a motion before any trial.
- 1 in 121 reached a trial (0.8%), after a median of 37 months.
- Median time from filing to the end of the case: 12.3 months.
- Almost none record a money award in this data (32 of 6,659), and the recorded figures are capped, so we do not publish an average.

Three Things to Watch For
Old settlement checks, a recent breach and a famous name make Duke Energy an easy hook:
“Your Duke Energy settlement check is ready”
The Ohio checks were paid out years ago, and no Duke Energy settlement is open now. A text or email asking for a fee or bank login to “release” a check is fake.
Calls threatening disconnection
Callers posing as Duke Energy demand immediate payment by gift card or app to avoid a shutoff, sometimes mentioning the data breach. Hang up and call the number on your bill.
“Join the Duke Energy class action” forms
You cannot sign up for the coal ash or nuclear pay cases; no class is certified. A page collecting your account number or Social Security number to “register” you is harvesting data.
Duke Energy Lawsuit — Questions People Actually Ask

The checks most people mean came from the $81 million Ohio rebate settlement, Williams v. Duke Energy, approved in April 2016 for Duke Energy Ohio customers from 2005 to 2008. The claim filing period ended long ago. No newer Duke Energy settlement is paying customers.
Is there a class action lawsuit Duke Energy customers can join right now?

How do I check a Duke Energy lawsuit claim for myself?
Duke Energy describes its major litigation in its quarterly SEC reports, and the Maryland court publishes its opinions. A real settlement notice names the case, court and administrator and never asks for a fee.
Separate from this case: were you injured in the last 2 years?
Class-action payouts are fixed amounts through an administrator. A personal injury claim is a different case — and often worth far more. Free estimate, no obligation.
