You should always read a plan’s EFL details to decide if it’s a fit for you, but our system does the tedious math to help you compare estimated costs. Of course, your future bill amounts will depend on your future usage.

You will find a widget on Home Energy Club which fetches your home’s energy usage data from Smart Meter Texas (SMT) and runs calculations of the rate structures of energy plans to help you conveniently estimate the cost of energy plans you are considering, based on your prior 12 months of energy usage as reported by SMT.

In one of the text panels of the widget, you will see an authorization button. By checking the permission box above the fields in which you enter your name and email address, and clicking on the authorization button, you are authorizing Smart Meter Texas to provide us with your location’s energy usage information so that our system can run cost calculations. It’s important to note that errors can occur when developing and running calculations, and the Company does not guarantee that its cost numbers are correct. You should always read the Electricity Facts Label (EFL) for each energy plan you are considering before enrolling, and make an independent decision on whether the plan is an appropriate fit for your home based on your own calculations and all the information disclosed by energy providers in the EFL.

ESID Lookup (ESI ID - ESI Number) - What is my ESID? - Home Energy Club™

What is my ESID?

How to Find it and Why You Need It

Your home’s electricity “ESID” (or ESIID, ESI ID, ESI-ID or ESI Number) number stands for Electric Service Identifier, and is a unique 17 or 22-digit number that tells utility companies that your residence has a meter and can receive electricity. 

It’s important to know your ESID when moving to a new home or switching electricity providers so that the utility company sends your electricity to the right place. Home Electricity Club’s look-up tool is simple and secure.

Input your address below to instantly find your ESID. 

Find My ESID

Who Uses ESIDs and Why?

ESIDs allow retail electricity providers (REPs) to identify which transmission utility company services your home. REPs buy electricity wholesale in the market and transmission utilities distribute it. REPs are the companies that customers interact with a majority of the time, as they are the ones that offer electricity plans and send you an energy bill.

The utility companies are called Transmission and Distribution Utilities, or TDUs. You’ll also see them referred to as Transmission and Distribution Service Providers, or TDSPs. These are the folks that are actually delivering the electricity to your home, and they maintain the power lines. 

Texas has multiple TDUs, all of which service different regions of the state. The largest ones are Centerpoint, which services the Houston area, and Oncor, which services the Dallas-Fort Worth area. 

When Do I  Need It?

Generally, the only time consumers need to look up the ESID is when they relocate or enroll in an energy plan with a new provider. Whether a residential or commercial address, the provider will need to know where the electricity they sell you is going. 

Where Do I Find My ESID?

Finding your ESID is easy. While the ESID is essentially the electricity meter’s virtual identification, it is not a physical serial number that you can find on the meter like a VIN on your car. 

The Electricity Reliability Council of Texas, or ERCOT, tracks who is serviced by which utility company through an online database of ESIDs. While it is possible to look up your ESID on this database, the easiest way is to use our lookup tool that is updated every day.

Some electricity providers will include the number in their customers’ monthly bill or list it in customers’ online accounts.

How Do I Get an ESID for My Newly Constructed Home?

Say you move into a new home and want to set up your electricity plan (that you found at a great rate because you shopped with Home Energy Club), but upon entering your address in our ESID lookup tool, you see a message that says your address wasn’t found. This usually just means that you are the first occupant of the place and need to get your meter set up. 

Newly constructed homes get new electricity meters. Consequently, they also require new ESIDs. Because TDUs are the ones who technically own all of the meters in their area of service, they are the ones that set the ESID.  It is up to the new occupants to contact the TDU in their area to get the new meter set up. 

Not sure which TDU services your area? Home Energy Club can help you get in contact with the right people.
