Im in Dallas, and had previously switched from TXU to Reliant. The last bill Reliant decided that the discount over 500 KwHours did not apply in the summer. I signed on to GEXA as well for the same price ($.0815). However I did it through www.enrergyoptimizers.net and did not have to post the deposit and was able to secure a one year contract at a fixed rate.
Thanks. It will be interesting to see how RRI's customer retention is affected by their rates in Houston, which are higher than even some of the renewable energy plans.
