What Does ESI ID Mean?

ESI ID stands for “Electric Service Identifier.” ESI IDs are unique service identification numbers assigned to every electric meter on a home or business in the state of Texas.

ESI IDs are used by retail electricity providers (REPs) to look up your billing and energy consumption history. REPs do not assign these IDs, they are actually created by the Electric Reliability Council of Texas (ERCOT).
