We are the largest competitive retail electric provider here in Texas in 3 years. The only ones bigger are the ones from the original monopoly. Our Green rates are cheaper than other people's standard coal generation. We are not a middle man as we are a REP (retail electric provider) here in TX.
Let me know how I can help and why it's important to read fact labels. If not, companies can charge you weird fees like $5/month for just being a customer! Wow, that is customer appreciation at it's best.
