What If ERCOT Has My Premise Type Wrong?
Your address is classified as residential or commercial by ERCOT. Here's what that means and what to do if it's incorrect.
You searched for an address and we told you it's classified differently than you expected. That classification comes from ERCOT, not from us — and sometimes it's wrong. Here's what's going on and how to fix it.
What Is a Premise Type?
Every electric meter in Texas has a premise type assigned by ERCOT — either residential or commercial. This classification determines which electricity plans you're eligible for. It's tied to your ESI ID (Electric Service Identifier), not your opinion of the property.
Why It Might Be Wrong
Premise types are set when a meter is first registered. If a property was converted from commercial to residential (or vice versa), the ERCOT classification may not have been updated. New construction sometimes gets the wrong code too.
Common Scenarios
These are the most common reasons people find their premise type doesn't match their expectations.
Home Office or Live/Work Space
Even if you run a business from home, the premise type is based on the meter classification — not how you use the space. A home-based business at a residential meter still shops residential plans.
Converted Property
Warehouses converted to lofts, storefronts turned into homes, or houses turned into offices may have an outdated premise type that doesn't match the current use.
Multi-Unit or Mixed-Use Building
Buildings with both residential and commercial tenants can have meters classified either way. Your specific unit's meter may not match what you'd expect.
New Construction
Newly built properties sometimes get classified incorrectly during initial registration. The builder or developer may have registered the meter under the wrong category.
How to Get It Fixed
If ERCOT has your premise type wrong, here's exactly what to do. It's not complicated — but it does take a phone call and some patience.
Find Your ESI ID
Your ESI ID is a 17 or 22-digit number on your electric bill. You can also use our lookup tool below to find it by address.
Contact Your TDU
Your TDU (Transmission & Distribution Utility) owns the power lines and meters in your area. They handle premise type changes — not your retail electric provider.
Request a Premise Type Change
Call your TDU and request a premise reclassification. They may ask for a certificate of occupancy, property tax records, or a letter from your city confirming the property type.
Wait for ERCOT to Update
Once your TDU processes the change, it gets sent to ERCOT. This typically takes 1-2 billing cycles. After the update, you can shop plans that match your new classification.

In the Meantime
While you wait for the premise type to be corrected, you can still shop plans using your current classification. The electricity is the same — the only difference is which plans are available to you.
