As they’re advertised, the Digital Discount plan appears to save you $4 — but only if you use 32 percent of your energy on the weekends, which is the stat Reliant used to create the average price it advertises. Say you often travel for business during the week, and are only home cranking the air conditioner on weekends. If your energy use skews to 55 percent weekend use (for Reliant, that means 8 pm on Friday through 12 am Monday), suddenly Truly Free Weekends becomes a much better deal.
The Electric Reliability Council of Texas (ERCOT) does it for you. When you sign up for a plan with a new provider, ERCOT will send you a mailer confirming the switch. You have three days upon receiving the mailer to change your mind. If you don't, you'll have a new provider within seven days, and ERCOT will notify your old provider. Just remember, if you abandon a contract before it's complete, you will be on the hook for any fees or penalties detailed in its Terms of Service.
Twenty-nine states have deregulated electricity, natural gas or both. That allows you to shop for the supply portion of your bill from alternative providers who may offer rates lower than the default supplier – usually a utility. Delivery services and billing will remain the responsibility of the local utility as they own the power lines and wires that keep the lights on.
