In general people have more negative things to say than positive when reviewing service companies.
There are a lot of negative reviews and some positive reviews on the over 20 retail electric providers serving the state of Texas.
To determine how to make sense of the reviews look at how they generally appear among all the providers and see which company has the abnormality.
When you find the abnormality that shows something above or below the norm you know you either are dealing with a good electric company or a bad company.
Sometimes the provider is new on the scene and has not gained a large following so also take that into consideration.
