Electrical District No. 3 (ED3) is a member-owned public power utility providing reliable electric service to residential, commercial, and agricultural customers in the Maricopa and surrounding areas of Pinal County, Arizona.
As a not-for-profit district, ED3 focuses on competitive rates, system reliability, and customer-focused programs such as prepaid metering, variable payment plans, and energy efficiency rebates. Timely bill payments ensure uninterrupted service, prevent late fees (2% with a $4 minimum after the past-due date), and support ongoing infrastructure upgrades.
Whether you need a fast one-time guest payment or full account management with AutoPay, ED3 offers secure, modern options through its SmartHub platform, along with traditional in-person and mail methods—all verified current as of April 2026.

Quick Pay (Guest Payment) – Fastest One-Time Option
ED3’s official Quick Pay feature lets members or guests pay their electric bill immediately without registering for a full SmartHub account. Simply navigate to the verified Pay Now link above, enter your ED3 account number (found on your monthly bill) along with your last name or ZIP code, and complete the secure transaction using a debit/credit card or bank account. Payments post instantly to your account, and you’ll receive email confirmation. This method is ideal for one-time payments, landlords, or anyone assisting a member. Official ED3 documentation confirms no processing fees apply when using SmartHub-linked payments.
SmartHub Online & Mobile App Payments
Register or log in at the SmartHub portal for complete control of your ED3 account. Features include viewing current and past bills, 15-minute interval usage data, paperless billing signup, outage reporting, and secure one-time or recurring payments. The free SmartHub mobile app (iOS and Android) allows payments anywhere with the same no-fee policy for debit, credit, savings, or checking accounts. Note: Due to a system transition in mid-April 2026, all customers were required to re-register for SmartHub; previous AutoPay settings may need updating.
AutoPay
Enroll in AutoPay directly through your SmartHub account or app. Choose to draft your full balance or a fixed amount automatically each month from a linked bank account or card. AutoPay is strongly recommended to avoid late fees and service interruptions. You can modify or cancel it anytime online. Guides for setup are available on the ED3 website.
Pay by Phone
Use the automated phone payment system 24/7 by calling (520) 424-9021. Follow the prompts to enter your account number and payment details securely. Customer service representatives are available during business hours but cannot process credit card or bank information over the phone—payments must be entered through the automated system or SmartHub app. Live support is also available at the same number for billing questions or payment arrangements.
Mail Your Payment
Mail a check or money order (payable to Electrical District No. 3) with your account number clearly written on the check or remittance stub. Allow 5–7 business days for processing. Send payments to the official mailing address: Electrical District No. 3 41630 W. Louis Johnson Dr. Maricopa, AZ 85138
In-Person, Drop Box & Retail Partner Payments
ED3 provides two convenient physical locations in Maricopa for in-person service and payments (Monday–Friday, 8:00 a.m.–5:00 p.m.):

At both offices you can pay in the lobby or use the secure after-hours drop boxes (checks or money orders only—no cash). For cash payments, use the Checkout by PayGo service at participating retailers including Walmart, Fry’s, CVS, Walgreens, Family Dollar, and Dollar General. Bring your bill barcode (accessible via https://ed3.sedccheckout.com/Lookup) or account number; a $1.50 vendor fee applies and payments may take 7–10 days to post. For immediate posting, use office or online options.
