The main difference between a provider and TDSP is that a TDSP is in charge of delivering electricity supply to a consumer's home or business. Contact your local TDSP for emergency situations such as hazardous electrical wires, storm alerts and power outages. Also, AEP offers McAllen residents and business owners with storm safety tips and service request information. Contact the TDSP at 1-877-373-4858 for electrical safety issues and 1-866-223-8508 for outage emergencies.
One of the most common sticking points for electricity customers is what, exactly, the difference is between an electricity provider (also called REP, CRES, or electric supplier) and an electric utility (also called a TDSP, TDU, or EDU). They’re both vital to the success of electricity deregulation, but they play very different roles. Understanding how they fit together can make a big difference in your overall confidence as an electricity customer trying to shop for the best electricity plan.
In Texas' deregulated energy market, customers must pick their own electricity provider, all of which offer different rates per hour of power usage. You can shop for other power plans on the state-run website,  www.powertochoose.org, or try an alternative website, like www.texaspowerguide.com to help find the cheapest plan. Keep in mind that many retail electricity contracts carry penalties for early termination.
When we looked at each provider’s offerings, we focused on plans with innovative pricing or attractive deals, then did the math to find out which would pay off over time. To our surprise, the results were all over the board. Green plans weren’t always more expensive than their traditional counterparts. Sometimes a fluctuating variable rate is still cheaper in the long run. Our takeaway: It pays to shop around. We’ll walk you through our analysis — so you can do the same as you compare rates.
Generation / supply price: What you pay. Unlike other states, Pennsylvania keeps cost per kWh easy to understand. Other states muddy the waters by including fees and discounts applied according to usage amounts in the quoted rate. PA companies show you you one steady rate. If you’re looking at a variable plan, this cost will reflect your first month only. If it is a special introductory rate, they’ll tell you how long it lasts.
Just as impressive: Its overall J.D. Power score for customer satisfaction. The 1,000 point score considers price, communications, corporate citizenship, enrollment and renewal, and customer service. At 709, Green Mountain Energy scored the highest of all Pennsylvania companies, well above the 669 state average, and a solid 20 points ahead of the next closest provider we looked at — Constellation.
Of FirstEnergy’s two plans, “Residential Fixed Price” (July 2019) and “Residential Fixed Price” (July 2020), the longer term contract comes with a reduced rate, per usual. If you’re hesitant to enter into a lengthy commitment because you’re planning to move within the next year or two, it’s nice to know that FirstEnergy builds a moving loophole into its cancellation policy. If you’re changing addresses and FirstEnergy does not service your new neighborhood, it doesn’t levy a cancellation fee. Opting out for any other reason comes with a $50 fee, cheaper than any other flat-rate cancellation fee we’ve seen. In fact, it might still be cheaper to go with the longer contract if you aren’t sure when you’ll move, or whether you can take your FirstEnergy service with you.
According to the EIA, the average American household uses 897 kWh of energy per month. Knowing that number, and how your own home’s usage compares, provides insight into the amount of energy you use per device. Our Energy Estimator will show you why simple changes like programming your thermostat or turning off televisions and computers when not in use will help lower energy costs.
