HB 478 Louisiana House · 2026 Regular Session

UTILITIES: Provides with respect to reimbursement for utility overcharges

HB 478 requires Louisiana water, gas, and electric utility companies to reimburse customers for overcharges by the next billing cycle. If a customer has disconnected service, the utility must send the reimbursement within 30 days to their recorded address. The bill mandates that all reimbursements be clearly labeled as "overcharge reimbursement." This applies directly to residential and business customers who were overcharged by regulated utilities under the Public Service Commission. The law aims to simplify and speed up the refund process for affected consumers.
