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.
If you think you have to pay the rates your current electricity provider charges, we have good news. The state of Texas allows you to choose which electricity provider you use. This means you can select a provider that has the cheapest Texas electric rates in your area and the best plan for your needs, whether you need a better deal for your residence, your business, or both. Thousands of consumers and businesses that have used our electricity rate comparison process agree that, when shopping for commercial electricity or residential electricity rates and plans, Vault Electricity is the one-stop source for the best options from top electric providers.

TDSPs or EDUs are the companies and people who own and maintain utility poles and power lines. They are the ones that you call when your power goes out. These utility companies are responsible for the physical delivery of electricity to your home or business. Before deregulation, everyone was required to buy their electricity from their local utility company.  With deregulation, the supply of electricity was opened to competition while the delivery of electricity continues to be regulated by the state’s public utility commission.
This company has more plan variety than any other we looked at, though most of them seem more flashy than functional. And some seem weirdly niche — like "Connect to Comfort," a 24-month plan that comes with a Hive Hub and a Hive Active Thermostat, smart home devices that allow you to control your heat and A/C via app. Like many of Direct Energy’s plans, how good of a deal it is depends on how closely its offers align with your established habits.
Generally, the generation of electricity is unrelated to anything on your bill. Power plant companies generate electricity and sell it to utilities as well as retail electricity providers in deregulated areas. The electricity is then resold to you, the customer. Transmission and distribution is taken care of and charged to you by your utility, regardless of what company supplies the electricity. These charges are separate from the supply portion of your bill.
It’s worth noting that you can switch for free with no exit fee 42-49 days before the end of your contract. Under Ofgem’s standards of conduct, energy firms have to give you between 42 and 49 days’ notice of your tariff ending. You can use this time to decide whether to stick with them, or switch. If you decide to switch, you won’t be charged an exit fee.
