How to Pay Your Tucson Electric Power Bill

Understanding Tucson Electric Power's Billing System

Tucson Electric Power (TEP) is the primary electricity provider serving the Tucson, Arizona area and surrounding regions. As of 2024, TEP serves approximately 460,000 customers across a service territory that spans about 6,000 square miles in southern Arizona. Understanding how TEP structures its billing system helps you manage your account more effectively.

TEP sends bills monthly to customers based on meter readings taken at your property. The bill reflects the electricity you consumed during a billing period that typically runs 28 to 35 days. Your meter is read on a regular schedule, and this information forms the basis of your charges. If you have a smart meter installed—which TEP has been deploying across its service area—readings may be transmitted electronically to company systems.

The typical TEP bill includes several key components: the base service charge (a fixed daily fee), energy charges (costs based on kilowatt-hours used), and any applicable taxes or regulatory surcharges. During summer months (June through September), TEP may apply seasonal rates that reflect higher demand periods. Winter rates apply during other months. If you have a time-of-use rate plan, your bill will show charges at different rates depending on when you used the electricity.

TEP also applies several other charges that may appear on your bill. Utility tax varies by city—Tucson residents typically see about 7 percent utility tax, while other jurisdictions have different rates. Regulatory surcharges cover costs related to wildfire mitigation, infrastructure improvements, and other regulatory requirements. Understanding these components helps you review your bill for accuracy and identify areas where you might reduce usage.

Practical takeaway: Keep a copy of your most recent TEP bill nearby as you explore payment options. Knowing your account number (typically an 11-digit number on your bill) makes the payment process faster for most methods.

Online Payment Methods Through TEP's Website

TEP offers a dedicated online payment portal where customers can pay bills directly through the company's website. This method works 24 hours a day, 7 days a week, and is one of the most widely used payment options. To access the online portal, visit tucsonelectric.org and locate the "Pay My Bill" option on the homepage.

To pay through the website, you'll need to either log into an existing account or make a one-time payment without logging in. For account holders, creating a login provides several advantages: you can view your bill history, see your current usage patterns, set up autopay, and receive email reminders about upcoming due dates. The registration process asks for your account number, zip code, and email address. Once registered, you can save payment methods for faster transactions in the future.

For one-time payments, you don't need an account. You'll enter your account number, the amount you want to pay, and your payment information. TEP accepts major credit cards (Visa, Mastercard, American Express, and Discover) and electronic bank transfers through ACH. However, credit card payments typically include a processing fee of approximately 2.95 percent, while ACH bank transfers have no additional fee.

TEP's online system also allows you to set up automatic recurring payments through autopay. With autopay, your payment is taken from your bank account on a date you select each month, typically around your due date. This removes the need to remember to pay manually each month. You can change your autopay amount or pause the service if needed by adjusting your account settings.

The online portal also provides options to view detailed usage information. You can see graphs showing your daily or hourly consumption, compare your usage to previous months, and identify which times of day you use the most electricity. This information helps you make decisions about when to use major appliances or adjust your thermostat.

Practical takeaway: If you set up autopay through the website and choose ACH bank transfer rather than credit card, you avoid processing fees while ensuring your bill is paid on time automatically each month.

Phone and Mobile App Payment Options

Tucson Electric Power provides a dedicated customer service phone line where you can pay your bill over the phone. Call 520-623-8700 to reach TEP's billing department. This option works well if you prefer speaking with a representative or have questions about your bill while making a payment. Representatives can take payments via credit card, debit card, or electronic bank transfer. Phone representatives are available during business hours, typically Monday through Friday from 8 a.m. to 5 p.m.

TEP has developed a mobile application available for both iOS and Android devices. The TEP mobile app allows you to pay your bill from your smartphone or tablet whenever convenient. The app provides the same functionality as the website, including viewing your bill, checking your usage, setting up autopay, and receiving notifications. You can download the app from the Apple App Store or Google Play Store by searching for "Tucson Electric Power" or "TEP."

The mobile app offers some features specifically designed for phone users. Push notifications can alert you when your bill is ready, remind you of upcoming due dates, and inform you about service outages or important company announcements. The app also provides information about TEP's time-of-use rates and allows you to adjust your account preferences on the go. Many customers find the mobile app useful for quickly checking their balance without logging into a computer.

Both the phone payment option and the mobile app charge the same fees as the website: no fee for ACH bank transfers, and approximately 2.95 percent for credit or debit card payments. The advantage of the phone option is the ability to speak with a representative who can answer questions about your bill or account. This may be helpful if you dispute a charge, want to discuss your rate plan options, or need to arrange a payment plan for a past-due balance.

Practical takeaway: Download the TEP mobile app if you prefer managing bills through your phone. Enable push notifications to receive reminders about due dates, which reduces the chance of missing a payment deadline.

In-Person Payment Locations and Mail Payments

Some customers prefer handling transactions in person or through traditional mail. TEP offers both options for those who want alternatives to online or phone payments. For in-person payments, TEP has a customer service center located at 88 East Broadway Boulevard in downtown Tucson. You can visit this location during business hours to pay your bill in person using cash, check, credit card, or debit card. In-person payments typically process immediately, and you receive a receipt confirming your transaction.

Several authorized payment locations throughout the Tucson area also accept TEP payments. These include select grocery stores, check-cashing services, and other retail locations. TEP's website maintains a list of authorized payment locations, which you can search by zip code. These locations provide convenience if you're already running errands in your neighborhood and want to combine tasks.

Mail payments remain an option for customers who prefer this traditional method. To pay by mail, write a check for your bill amount and include the payment coupon from your paper bill. Mail your payment to the address shown on your bill, which is typically TEP's payment processing center. Allow 7 to 10 business days for a mailed payment to clear your account. Always send mail payments well before your due date to account for transit time.

If you pay by mail, consider including your account number on both the check and envelope to ensure the payment is applied to the correct account. Never send cash through the mail, as it can be lost or stolen. When mailing a payment, keep a record of the date you mailed it and the amount. If your bill shows as past due before your mailed payment should have been received, contact TEP's customer service to confirm they received your payment.

In-person and mail payments typically have no additional fees, making them cost-effective options compared to credit card processing fees. However, they require more time and effort than online or automatic payments. Some customers combine methods—for example, using autopay for regular monthly payments and occasionally paying in person if they have a credit balance they want to apply to next month's bill.

Practical takeaway: If you mail a check for payment, write your account number on the check itself and mail it at least two weeks before your due date to prevent late payment fees.
