No. When you’ve chosen a new deal, your new supplier will handle the switching process. They’ll contact you to let you know what date you’ll be transferred over, and they’ll contact you around the switching date to ask for a meter reading. They’ll pass this on to your old supplier so they can send you a final bill. You don’t need to contact your old supplier, as the new supplier will handle everything for you.
Another unwelcome side effect of not knowing your average monthly kWh usage level is that you may end up paying more than you expect. This can occur when a customer inadvertently shops an electric rate based on a higher usage level than they actually use. Electricity suppliers commonly advertise their electric rates associated with the highest (2000 kWh) usage levels since those tend to be the lowest rates.
The growth in wind power and natural gas fueled power will offset the loss in coal over time but for the summer of 2018, expected record demand for electricity will converge with power plant closures to put a squeeze on wholesale electricity rates. This, in turn, will cause the retail electricity prices paid by most Texas consumers to increase. The rise in wholesale rates could be particularly dangerous for consumers who have electricity plans that are tied directly to the wholesale price of electricity.
Keeping on top: With deregulation, a whole host of electric resellers jumped into the market because there’s a whole lot of electricity to sell: if Texas were a country, it’d be the 11th largest electricity consumer in the world! Just by itself, it uses as much electricity as Spain or Great Britain! That means there’s a whole lot of information you have to find, absorb, and process to make sure you’re getting the best rate for your needs.
