What Others Say

“Thanks so much for RateGrinder; saved me lots of time and headaches!”
– Debbie A.
Houston, TX
“When I plugged my data into Rate Grinder, it came up with exactly the plans that I had spent hours and hours number crunching”
– Tony L.
Houston, TX
“For years I have been frustrated with Power to Choose. There is no way I could sort through all of the options, much less get an idea of what my true energy cost would be. As a result I’ve overpaid for a variable rate plan because I felt I could not make an informed decision. Texas Power Guide does all the work for you! Thanks so much for putting this product out there. I wish I had found it years ago.”
– Jonathan C.
Fort Worth, TX

Detailed Instructions

Follow the steps below.  (If you downloaded RateGrinder to your PC or laptop, you might have to enable ‘editing’ first.)

Step Instructions
1 Enter your ZIP Code and any filtering preferences in the yellow cells.  RateGrinder enter filters
2 Enter your monthly electricity usage from either:

  • Your past electric bills, or
  • The free site:
    • Create or Login to your account
    • Navigate to the “Usage” tab, then “My Usage” screen
    • Under “Report Option” \ “Report Type”, select “Monthly Usage”
    • Copy your 12 monthly “Actual kWh” numbers from the bottom table

The more usage data you enter, the more accurate your results will be.
If you only want a 3 – 9 month plan, enter zeros for the unused months.

 RateGrinder enter monthly usages
3 Highlight key Electricity Facts Label (EFL) details and graph your predicted rates by entering ‘1’ (or another plan’s rank from the ‘Results’ table) into the colored cell.  RateGrinder pick plan to graph
4 Choose a plan by the Annual Cost1 and (optionally) company rating, then sign up online via its “Sign Up” link. By law, your new provider will completely manage the switch. You don’t need to inform your old provider, and there’s no risk of electricity loss. When signing up, make sure your final EFL’s  name, date, and version # match those shown in RateGrinder, as some EFL offers change DAILY.  RateGrinder find lowest cost
5 If using RateGrinder saved you time and money in choosing your electricity plan, please click the “Buy Now” button to support TPG with $10 per new contract you sign. Or help us spread the word to a friend and save $5!

6 Sign up for RateAlert or set your own reminder to come back and shop for your next plan when the new one ends. You can switch within 14 days of your contract’s end date without incurring termination fees. DON’T FORGET, or you’ll give up much of your savings to an expensive month-to-month default plan.

1 Calculated cost includes recurring energy and TDU charges, but not minor PUC fees, taxes, etc. RateGrinder summarizes non-recurring REP fees (for services like paper billing and non-automated payment) on the bottom-right table. See ‘Charges and Fees’ for more details.


Some plans change daily, so if you’re working off a previous day’s downloaded file, you’ll see a link at the top to bring you back here for the latest release.

When downloaded, RateGrinder works with Microsoft® Excel® 2007 or newer, and possibly on older versions with some limitations. If you find an incompatibility, data error, or omission, please let us know at
