Louisiana utility customers who get overcharged now have a hard deadline working in their favor. A new state law, Act 553, requires water, gas and electric providers across Louisiana to reimburse overcharged customers in full within 90 days of when the error is discovered or reasonably should have been discovered.
The law took effect in August 2026 and was authored by Representative Alonzo Knox, a New Orleans Democrat, according to WVUE. Knox said Louisianans should not accept being overcharged for a service not rendered, framing the measure as a basic fairness fix for household budgets already stretched thin by rising utility costs. The measure became law before taking effect in August 2026.
The law goes beyond a simple refund mandate. Per the Louisiana State Legislature, regulated utilities must explicitly label reimbursements as an “overcharge reimbursement” or similar phrasing directly on customer bills, and companies must mail refunds to a former customer's last known address if that person's service has already ended.
New Orleans Residents Are Divided
Reaction on the ground in New Orleans has been mixed. Alvin Branch expressed skepticism about whether the new law will actually change anything for customers dealing with utility disputes. Richard Gatlin, by contrast, supported the 90-day reimbursement requirement, saying the fixed timeline lets customers plan around receiving their money instead of waiting indefinitely on a company's own schedule.
The law applies to regulated utility providers covered either by the Louisiana Public Service Commission or by a local governmental subdivision.
LAWCO and the commission’s Consumer Complaint Tracking System are also mentioned in connection with customer complaints.
Why Billing Errors Have Drawn Scrutiny
The push for a firm reimbursement deadline follows a string of high-profile billing failures. In October 2025, Entergy Louisiana corrected a $9,000 gas billing error for a Baton Rouge couple whose monthly bill had spiked from $199 to $957, according to WBRZ.
New Orleans has its own history with billing breakdowns. A March 2020 performance audit by the Louisiana Legislative Auditor examined the Sewerage and Water Board of New Orleans. The Sewerage and Water Board of New Orleans has also been the subject of evaluation involving its drainage and financial operations. Earlier utility-related matters also form part of the broader context surrounding Louisiana ratepayers.
Before Act 553, general billing disputes fell under the Louisiana Unfair Trade Practices and Consumer Protection Law, which set a 10-year statute of limitations for written contract claims and three years for open accounts, according to DocDraft. Those timelines governed how long customers had to dispute a charge.
Part of a Broader Affordability Push
Knox introduced HB 478 as part of a wider consumer affordability package in March 2026, alongside HB 800 targeting grocery price regulation and HB 472 authorizing local rent stabilization, according to WBRZ. Three-quarters of U.S. adults said their home energy costs have increased in recent years, Pew Research Center reported in May 2026, underscoring the financial backdrop against which lawmakers built the reimbursement mandate.
That backdrop includes state-specific pressures on Louisiana bills. State solar policies and federal clean-energy tax-credit rules have also been part of the energy-cost backdrop.
Utility cost fights remain active at the Public Service Commission on other fronts too. In August 2026, commissioners delayed a vote on nuclear fee costs over whether ratepayers or energy companies should pay for feasibility studies on small modular nuclear reactors, a separate dispute over who ultimately covers pass-through charges on customer bills.
What remains unresolved is how enforcement will actually work. It is not yet clear how regulators will monitor when a utility reasonably should have discovered an overcharge, or what recourse customers have if a provider misses the 90-day window entirely — questions that will likely shape how much practical difference Act 553 makes for people like Branch and Gatlin.
