Review site for energy suppliers

Hi everyone! Does anyone know where I can read customer reviews of energy supplier companies such as TEPCO. I want to choose the best electricty company but I want to read a review first, I tried [kakaku.com](https://kakaku.com) but there are no customer reviews.

Thank you in advance!

  1. I use ENeos Denki, and honestly, there’s not much difference in price those days.
    By using Eneos Denki, I save 30yen per month… They are all about the same.
