Notice and timing
How delinquency is handled
Grace period after the due date
Residential bills must provide a due date not less than 23 days after postmark or delivery. The bill's printed due date governs delinquency; the tariff does not create a general post-due-date grace period beyond that minimum notice period.
Late-fee calculation
The current tariff lists a late-payment fee of 1.5% per month on the unpaid balance. Additional charges can include the $0.09 ICC assessment, approved riders, taxes, and a $15 returned-check fee where applicable.
Disconnection timeline
The tariff establishes delinquency when a residential bill is not paid by its printed due date, but the reviewed public materials do not publish a single universal calendar-day path from due date to disconnection because notice timing and protections are regulated and account-specific. Contact 1-800-422-2782 before the due date to request an installment plan, preferred due date, or medical-emergency protection.
