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.
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.
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.

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.
CenterPoint Intelligent Energy Solutions LLC, IES, which manages TrueCost, is not the same legal entity as CenterPoint Energy Resources Corp. (CERC) or CenterPoint Energy Houston Electric, LLC (CEHE), nor is IES regulated by the Railroad Commission of Texas or the Public Utility Commission of Texas. You do not have to buy products or services from IES in order to continue to receive quality regulated services from CERC or CEHE.

There are many different options for term lengths in the Texas energy market. Different term lengths often have different price points, so if you’re more flexible with the length of your contract, you could get a cheaper rate. Contracts with shorter term lengths are great if you prefer to avoid a long-term commitment while longer contracts usually provide the benefit of longer-term price stability.
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. Please see your Terms of Service for more information.

According to The Watchdog, the broker SaveOnEnergy hosts powertochooseTX.com and powertochooseTX.org, among many others. These sites – although branded as SaveOnEnergy – can appear to offer quotes from all available electricity suppliers in a given zip code, just as you would find on the PUCT’s PowertoChoose.org. But in reality, the only offers listed on this site are from suppliers who contract with SaveOnEnergy to sell residential and commercial plans on their behalf.
Not understanding the system, I overpaid — but I quickly grew tired of that. I decided to educate myself. Eventually, I figured out a system. My Watchdog Nation Guide to Electricity Savings is built on the idea that companies should be judged two ways — by lowest rate and by company reputation. When the stars align, the right company is obvious. (Note: This doesn’t apply to customers in mandatory electricity co-ops or municipal-owned utilities.)
In order to prompt entry into the market, the price to beat would have to be high enough to allow for a modest profit by new entrants. Thus, it had to be above the cost of inputs such as natural gas and coal. For example, a price to beat fixed at the actual wholesale procurement price of electricity does not give potential entrants a margin to compete against incumbent utilities. Second, the price to beat would have to be reasonably low, to enable as many customers as possible to continue to consume electricity during the transition period.

After Senate Bill 7 went into effect in January 2002, nearly 6 million power customers became eligible to choose their energy supplier. That number has grown through the years. By deregulating the state’s energy market, the Texas Senate gave constituents the power to choose. The process of energy deregulation in Texas dismantled the utilities’ monopoly over the electric market and encouraged customers to explore their energy options.
You can switch power supply providers to find more agreeable terms, snag a better rate or get green electricity. If you have a month-to-month plan for your power supply, switch at the end of any billing month. If you are locked into a longer contract and want to exit early, you may want to investigate what fees may be assessed if you switch. Power supply will be the same when you switch power providers, so you don't have to worry about sub-standard electricity supply.

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.
