How to Reach EPB for Service Issues, Billing Questions, and Account Changes in Chattanooga

Contacting your electric and fiber provider directly matters when you're dealing with an outage, disputing a charge, or upgrading your internet speed. This guide covers the primary ways to reach EPB (Electric Power Board), what each contact method handles best, and what information you should have ready before calling.

The Main Phone Line

EPB's primary customer service number is 423-648-1372. This line handles account inquiries, billing questions, service requests, and outage reports during business hours, Monday through Friday, 8 a.m. to 5 p.m. Central Time. The system routes calls based on whether you're calling about electric service, fiber internet, or billing. If you're calling outside those hours, a recorded message directs you to the after-hours emergency line for outages and safety issues.

Calling this number works well for questions about your recent bill, requests to add or remove services, and scheduling appointments for installation or repairs. Wait times typically run 5 to 12 minutes during mid-morning hours and stretch longer between 4 and 5 p.m. Have your account number (found on your bill) available when you call; it speeds up routing and verification.

After-Hours and Emergency Line

For outages, downed lines, or electrical hazards, EPB operates a 24-hour emergency dispatch at 423-648-1373. This separate line exists because infrastructure problems cannot wait for business hours. If you smell gas, see arcing power lines, or lose electricity during a storm, use this number. The system immediately logs outages and dispatches crews.

Even if you're calling at 2 a.m., the after-hours line lets you report the problem, receive an estimated restoration time, and receive updates via text or email if you opt in during the call. For neighborhood-wide outages in areas like North Shore, St. Elmo, or Eastgate, the system recognizes widespread issues and prioritizes them accordingly.

Online Account Management and Outage Maps

EPB's website lets you check your balance, pay your bill, and report an outage without calling. The online outage map shows real-time disruptions across Chattanooga and surrounding service areas, breaking down active outages by location and estimated restoration time. If you experience an outage in Hixson, East Brainerd, or downtown, the map clarifies whether it's neighborhood-wide or isolated to your block, which changes how urgently crews will respond.

The account portal also lets you view your usage history, compare your electric consumption month-to-month, and track your fiber internet bandwidth. For renters in multi-unit buildings or residents in areas where EPB recently expanded fiber service, the portal confirms whether fiber is available at your address.

When to Call Versus When to Use Online Options

Calling works better when you need to negotiate a payment arrangement, dispute a charge, or discuss billing adjustments after a prolonged outage. The phone agent can review your account in detail, explain unexpected charges, and process one-time exceptions. Online tools work faster for simple tasks: reporting an outage, paying a bill, or confirming service availability.

If you're switching between electric-only and bundled electric-plus-fiber service, or if you need to schedule an electrician to run new lines to an addition or home office, a phone call ensures you get the right crew assignment and pricing quote. The 423-648-1372 number connects you to someone who can arrange this within 24 to 48 hours in most Chattanooga neighborhoods.

Billing and Rate Questions

EPB's rates are regulated by the Tennessee Public Utility Commission, but the utility itself sets its own rate structure. If your bill jumped significantly, the phone agent can break down what changed: whether a seasonal rate adjustment occurred, whether your consumption spiked, or whether you were billed for a service upgrade. Chattanooga residents pay different rates than those in surrounding areas like Collegedale or Ooltewah (outside EPB's service territory), so comparing bills with neighbors helps confirm whether an increase is system-wide.

For fiber customers, bandwidth overage charges or promotional rate endings often explain unexpected jumps. The agent can clarify which promo ended and whether faster tier speeds would cost less per gigabyte. Chattanooga's fiber coverage now extends into East Brainerd and parts of North Shore, so availability and pricing differ block by block.

Setting Up Automatic Payments and Notifications

Both the phone line and online portal let you enroll in autopay, which eliminates the need to remember due dates. You can schedule it for any day of the month after your bill date. Email and text alerts notify you when your bill is ready, when a payment processes, and when outages occur in your area.

For people managing a property remotely or for elderly residents who want family members to stay informed, EPB allows multiple contact numbers for outage notifications. If you own rental properties in different Chattanooga neighborhoods, the account settings let you add contacts for each address.

Backup Contact Methods

If the main line is busy or if you need written confirmation of a service request, EPB maintains a mailing address: EPB Customer Service, 10 West Martin Luther King Boulevard, Chattanooga, TN 37402. Mail takes 5 to 7 business days, so this option works only for non-urgent inquiries.

Social media accounts on Facebook and Twitter are monitored during business hours, but they are not reliable for account-specific issues because they cannot handle private billing information over public channels.

What to Know Before Calling

Write down your account number, the date and nature of your issue, and any previous conversation reference numbers if this is a follow-up call. Have your billing address confirmed, especially if you rent and your mailing address differs. If you're reporting an outage, note which streets or landmarks define your block so the dispatcher can pinpoint the affected area.

Having this information reduces hold time and prevents the agent from transferring you multiple times. For service appointments, confirm that someone will be home and ask about the crew's arrival window so you're not waiting all day.

Reaching EPB efficiently means matching your contact method to your need: phone for disputes and negotiations, online for outage reports and bill payments, and the after-hours line for emergencies. In a city where power and fiber infrastructure support both residential reliability and remote work, getting the right answer quickly matters.
