Our condominium association has enjoyed StarTex for about three years now and they are definitely super. We locked in a rate and really enjoyed turning the thermostat up or down without tears when we got their bill. Super service/customer support. ”

great choice
(4.9 / 5)
“
On moving to Texas, we were confronted by choosing an electric company. This was overwhelming. I did research on Texas companies, and read a lot of material. I chose StarTexPower, and have never looked back. The rate I pay is such a savings over my previous experience in another state. There have been no problems with this company. I like the way they do business, and will remain a loyal customer. ”

The Benefits of Choice
(4.9 / 5)
“
The benefits of choice are clear when you work with StarTex Power. I didn't realize how good I had it until I moved away. But from start to finish, and at every point in between, StarTex went above and beyond to deliver competitive prices and excellent customer service. I was most impressed when a VP picked up to answer a billing question. You just don't find that service elsewhere. I miss having the option to choose a power company. But if I ever make it back to Texas, StarTex is the choice for me! ”

Honest and dependable company
(4.9 / 5)
“
First company I switched to who was honest with their rate. They didn't add any unexpected charges like the other 2 companies I used. I will stay with them forever unless they do the same thing to me in the future but I don't expect that to happen. Also, it's great to do business with a company here in Texas. ”
