Fixed-rate supply plans offer price-protected supply rates for the length of a term agreement. The price per kilowatt hour (kWh) will remain the same throughout your term, even if the market price fluctuates. A fixed-rate supply plan can range from three months to five years, so it’s important to find the term length that works best for your situation.
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, Compare Electricity Rates 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, Power Company , the TDU for Corpus Christi, charges the same delivery fee for all Lowest Electricity Rates, Compare Electricity Rates, and Cheapest Electric Company 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.
It would be a good idea for you to learn about whether or not a company charges you to interact with its Customer Service Department in any fashion. A company might offer affordable energy rates on the surface, but if they charge you to pay online or over the phone with a credit card, or to make even the most basic of phone calls to Customer Service, then you're not really saving that much money.
In this free market competing electricity retailers buy electricity wholesale from private power generators to sell at retail to around 85% of Texas residents. The partnership between generators and retailers is governed by the Electric Reliability Council of Texas, or ERCOT, which attempts to balance the power grid’s electricity supply and demand by purchasing small amounts of electricity at 15-minute intervals throughout the day.
