Due to the increased usage of natural gas immediately after deregulation, new-era energy tools such as wind power and smart-grid technology were greatly aided. Texas' first "renewable portfolio standard" — or requirement that the state's utilities get a certain amount of their power from renewable energy like wind — was signed into law in 1999, as part of the same legislation that deregulated the electric market.
Fixed-Rate Plans: These plans are steady and predictable; the price per kWh you sign up for will remain that same for the entirety of your contract. (The only changes in your bill will be from forces outside of your REP's control, like changes in TDU fees, or changes in federal, state, or local laws.) Often fixed-rate plans will have a slightly higher price per kWh than others, but you're paying for the predictability. They're great if you live by your budget – and even greater if you happen to sign up when rates are low. The fixed-rate plans of our five Texas providers typically started at 12 months, with some extending up to three years, but we spotted a couple from Reliant that offered fixed rates for six month contracts as well.
Utility companies are responsible for transmission and delivery of electricity even in energy deregulated parts of Texas and should be contacted in the event of a power outage. Your retail energy supplier may provide you competitive electric rates or exceptional customer service, but they cannot repair power lines or restore your service. In the case of an emergency, contact:
“Retail electricity providers” began offering the sale of electricity supply shortly after deregulation began. Texans are not required to switch to a retail electricity provider, and will continue to receive the supply of electricity from their default utility until they decide to switch. Utilities have no incentive to supply electricity since they are required by law to resell electric supply at no profit. The utilities can only profit from the transmission and delivery of the electricity – which is not affected by which company sells the supply of electricity. Since the utilities often charge higher rates than electricity providers, there is little reason to stay with the utility for electric supply.

5Green energy plans are supported 100% by Renewable Energy Certificates (RECs) that are purchased and retired in an amount sufficient to match your annual consumption. RECs are a tradeable, non-tangible energy commodity in the United States that represents proof that 1 megawatt-hour (MWh) of electricity was generated from an eligible renewable energy resource like biomass, hydro, solar or wind.

We often get asked by our subscribers “what is the best electricity company in Texas?”. There are a lot of electricity companies in Texas, so it’s no wonder you want to know what the best electricity companies in Texas are. However, there really isn’t such a thing as one “great” energy company. Of course, there are some companies that are both reliable and well-known. These include Reliant, Direct Energy, TXU, and Gexa. However, when you shop around for an electric provider you’ll find that they all offer competitive rates. Just make sure there aren’t any hidden fees on their plans, as this is what makes them a better choice.

TDU Delivery Charge: TDU stands for transmission and delivery utility — in other words, the utility company in your area that is actually piping the energy from the power generation companies into your home. (Remember, REPs in Texas are just the middleman.) The TDU delivery charge is set by the utility and is consistent from plan to plan and provider to provider within its service areas. For example, AEP , the TDU for Corpus Christi, charges the same delivery fee for all TXU, Direct Energy, and Reliant plans. You don't typically get a choice in utility company, and therefore, these fees are pretty much unavoidable, non-negotiable, and won't factor into choosing an electricity plan or provider.
