How to Download Your Smart Meter Texas Data (Step-by-Step)

Every Texas homeowner in a deregulated area has access to incredibly detailed electricity usage data - most people just don't know it exists. Your smart meter records how much electricity you use in 15-minute intervals, 24 hours a day. That data is the key to finding the cheapest plan for your actual usage pattern.

Here's how to get it.

What Is Smart Meter Texas?

Smart Meter Texas (SMT) is a state-run website that stores your electricity usage data. It's managed by the transmission and distribution utilities (TDUs) - Centerpoint, Oncor, AEP, and TNMP - not your retail electric provider.

Every meter in a deregulated area automatically uploads readings. You just need to register and download the file.

Step 1: Create Your Account

Go to smartmetertexas.com and click "Sign Up" in the top-right of the login box.

You'll need:

• Your ESIID (Electric Service Identifier) - a 17-digit number found on your electricity bill
• Your meter number - also on your bill or on the physical meter
• A valid email address

Select "Residential" from the account type dropdown, then fill in the registration form. The key fields are your ESIID and Meter Number under "Security Information."

The registration process takes about 5 minutes. You'll get a confirmation email to verify your account.

Step 2: Log In and Export Your Data

Once logged in, you'll land on your Dashboard. This is where you'll set up and download your usage export.

Here's what to do:

1. Set the Report Type to "Energy Data 15 Min Interval" (this should be the default)
2. Set the Start date to 12 months ago - we recommend a full year for the most accurate audit
3. Set the End date to today
4. Click "Export My Report" - the CSV file downloads instantly

You'll also see a "Green Button Download My Data" option - either method works, but "Export My Report" is simpler.

The file will download to your computer. It's typically 2–6 MB depending on how many months you selected.

Step 3: What's in the File?

Your CSV contains a row for every 15-minute interval:

| Column | What It Means | |--------|--------------| | DATE | The calendar date | | USAGE_START_TIME | Start of the 15-min window | | USAGE_KWH | Electricity consumed in that window | | CONSUMPTION_SURPLUSGENERATION | "Consumption" for usage, "Surplus Generation" for solar export |

A full year of data gives you roughly 35,000 rows - one for every 15 minutes of the year. This is what makes a truly personalized audit possible.

Step 4: Run Your Audit

With your CSV in hand, you have two options:

Option A: Full Audit - Upload your CSV at watttrimaudit.com for a detailed month-by-month breakdown. The file never leaves your browser - we parse it locally and only send summary numbers to calculate your savings. Option B: Quick Estimate - Don't want to bother with the CSV right now? Use our free Quick Estimate - just enter your average monthly usage and current rate. You'll get instant savings results in 30 seconds.

Why 12 Months Matters

Texas electricity usage is wildly seasonal. Your August AC bill might be 3x your March bill. Plans that look cheap based on one month's usage might be expensive across a full year.

A 12-month CSV captures your summer peaks, winter lows, and everything in between - so the audit matches your real-world usage pattern, not just a snapshot.

Tips

• Can't find your ESIID? Check the top of any electricity bill, or call your current provider - they'll give it to you
• New to your home? You can still register - the meter data follows the address, not the account holder
• Solar customers: Your CSV includes both import and export rows, so we can calculate your net usage and find the best buyback plan

Browsing plans is a great start - but every home uses electricity differently. WattTrim analyzes your actual Smart Meter usage data to find the cheapest plan for how you use power, not just a generic benchmark.
