Fixed – If you're a homeowner in areas such as near Milam Elementary School, The Champions Course, Lucy Park or downtown, explore electricity in Wichita Falls with fixed supply rates. This type of plan, unlike the variable-rate plan, secures a rate per kWh that remains the same for a contract term. There is typically a cancellation fee, however, that is waived if you move and notify your provider of your new address.
The Texas Senate Bill 7, passed in 2002, gave 5.6 million Texans the power to choose a retail electric provider (REP) to supply electricity to their home or business. This bill facilitated a competitive energy marketplace that 85 percent of Texans can capitalize on today. Energy choice is available to residents in Houston, Dallas/Fort Worth as well as other cities in Texas.
An ILEC is a telephone company that was providing local service when the Telecommunications Act of 1996 was enacted. Examples of ILECs serving South Dakota are Golden West Telecommunications, Cheyenne River Sioux Tribe Telephone Authority and Beresford Municipal Telephone Company.

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.
