Thank you for giving us your information so that we
can send you our best rates when you need them.

We will soon send you a link to our Savvy Shopper's Guide. It includes:


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.
