It would be a good idea for you to learn about whether or not a company charges you to interact with its Customer Service Department in any fashion. A company might offer affordable energy rates on the surface, but if they charge you to pay online or over the phone with a credit card, or to make even the most basic of phone calls to Customer Service, then you're not really saving that much money.
Texas electricity rates are on their way down again. After a summer spike, electricity rates across Texas have fallen. Utility officials were concerned about having enough electricity to meet peak summer demand. This resulted in electricity providers increasing the rates on their fixed rate plans in anticipation of higher wholesale electricity prices.
In this free market competing electricity retailers buy electricity wholesale from private power generators to sell at retail to around 85% of Texas residents. The partnership between generators and retailers is governed by the Electric Reliability Council of Texas, or ERCOT, which attempts to balance the power grid’s electricity supply and demand by purchasing small amounts of electricity at 15-minute intervals throughout the day.
