An ESI ID (also styled as ESI-ID) is an “Electric Service Identifier,” a unique number assigned to every meter connected to a home or business in the state of Texas. An ESI ID number identifies your electric service location. Some addresses can have multiple ESI IDs — apartment complexes, for example — but each unit will still have a separate ESI ID.

This search form works for finding both residential ESI IDs, as well as ESI IDs for businesses.
Why or when do I need my ESI-ID?
Whether you’re shopping for a new electric plan for your home or business, you’ll need to have your ESI ID number(s) handy. ESI IDs allow retail energy providers (REPs) to lookup a history of your previous electric bills (which include your costs, consumption, etc). A provider will use your ESI ID and the information it provides to help verify your identity and calculate possible savings by switching to a particular electric rate or plan.
