Shopping for a deregulated energy plan can seem overwhelming. With the sheer number of potential energy providers, many find it difficult to narrow down their options. Choose Energy wants to help empower consumers to find the right electricity plan at an affordable rate.

To ensure that our customers are able to choose a great energy provider, Choose Energy compiled a scoring model to review some of the top electric providers in our marketplace. The Choose Energy reviews model is based on unbiased and quantitative criteria to ensure provider scores remain objective.

We’ve broken down our scoring model into three main categories: customer service, online accessibility and business history. These categories contain the following items:

  • Customer service

Using these criteria, Choose Energy assigns impartial reviews to top electricity providers in deregulated areas. To learn more about electric provider reviews, see our full list here.

In the customer service category, the P2C complaint score is taken from the Public Utility Commission of Texas’ most recent scorecard, which can be found here.
