Been with Star Tex for 3 years

(4.2 / 5)

“  I've been with Star Tex Power for 3 years now and they have easily saved me thousands of $$ No complaints and a staight forward, guaranteed rate.

Just a simple bill that I pay on time each month electronically.

Hard to beat them. ”

Very pleased

(4.2 / 5)

“  After searching several different electricity providers in my area I found Star Tex to have the lowest rates. I have renewed with them 2 times and found they ahve been a good provider with above average customer service (Not the best but certainly not the worst) It's like gas we all use it so we all have to pay for it. You look for good gas prices don't you. Be sure if you apply on line and everything looks like it is set call and talk to a PERSON and verify that was my only complaint. The service I requested online was not what was registered with the office they did correct everything. ”

Not perfect, but close. Offers 100% wind power

(4.2 / 5)

“  Prices when I signed up for StarTex Power were very good. Then the contract ended and I wasn't a "new" customer anymore. Problem is, the competition, their rates went up too and with all the bad stuff I'd heard about other companies, I decided to stay with StarTex. It's been a good move.When I saw they offered 100% wind power, I was very happy to sign up for it. Rates for renewable energy are a bit higher than regular rates, but if enough of us sign up for it and create the demand, it should drop. In the meantime, this review is powered by the wind. I love that! ”

Very good 24 month deal

(4.2 / 5)

“  The only problem is that if you chose to pay online at they website,there is a $2.95 charge.
At my previous companies,Infinity Energy or Atlanta Gas,there was no online charge.
On the good side,i can avoid this charge by paying online thru my bank.
But the reason i was paying to the gas companies directly was to make points to my credit card. ”

Better pricing

(4.2 / 5)

“  I had been with another provider for more than 2 years at a rate of $.49 per therm. I admit that it was my fault that I did not go back to request another contract price. However, any good provided would have alerted me to ask for another price so that they could keep my business. Instead they decided to raise the rate to $ 1.196 per therm. Even if they had been $ .10 per therm more I would have likely stay with them. Anyway what I did was to look for a better deal and I was obliged to go Constellation for a two year deal which was 1/3 the price of my old provider and Im now very pleased with the outcome and I will like stay with Constellation. ”

Poor customer service

(4 / 5)

“  Customer service called and offered a reasonable price for electric, only to find out later we can not use Constellations, if we do not use National Grid.
We are allowed to choose our electric company, but not our gas supplier ”

Read the EFL fine print

(4 / 5)

“  Order was easy. Account transfer no problem. First bill was higher than EFL facts said it was going to be. The distribution charge from the electric distributor was about $10 higher than what EFL said. Called Constellation and asked why, they said distribution charges had gone. They went up the first month after I switched. False advertising by Constellation. ”

Good ride for 10 months

(4 / 5)

“  Had some billing issues early on, but not exactly providers fault. All in all everything was great, however as always good things don't last. Provider probably won't make my current plan available on renewal as it was more likely promotional to attract business, so will have to look for affordable options elsewhere to keep costs in check ”

Review

(4 / 5)

“  There should be an online method to renew policy... Either I was not patient or the rep talked slowly, either way when I'm at work taking the time out for all the repeated question was a bit weary. When someone satisfied with the services, the option to renew is given. ”
