Electrical District No. 3 (ED3) is pleased to announce the launch of a major enterprise software upgrade on 4/13/2026. This upgrade will modernize the way ED3 manages customer accounts and delivers services, bringing powerful new tools and real-time information directly to our customers. We want to ensure all account holders are fully informed and prepared for this transition.

What’s Changing on 4/13/2026

• New Account Numbers: All account holders will be assigned new account numbers as part of the system migration.
• SmartHub App Replaces the ED3 App: For best experience, please download the new Smarthub app on your smartphone or other device. This offers an improved customer experience and real-time usage data.
• Real-Time Usage Information: Customers will have access to up-to-the-minute energy usage information through the new SmartHub app and online portal.

Action Required by Customers

To ensure uninterrupted service, all customers will need to take the following steps after 4/13/2026:

• Re-enroll in AutoPay: All customers currently enrolled in automatic payments will need to re-enroll in AutoPay after the system goes live on 4/13/26.
• Re-enroll in Paperless Billing: Customers enrolled in paperless billing will need to re-enroll to continue receiving electronic statements.
• Re-enter Credit Card Information: Credit card information will not be carried over to the new system. Customers will need to re-enter their credit card details through the SmartHub app beginning 4/13/2026. Please note that in compliance with applicable laws, customer service representatives will not be permitted to accept or process credit card or banking information over the phone. All payment information must be entered directly by the customer through the secure SmartHub app.
• Register for SmartHub: Beginning 4/13/2026, customers can register for the new SmartHub app to manage their account, view real-time usage, and set up payment preferences.
