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. See a complete list of ILEC companies (18 KB). Some companies, such as Qwest, Midstate Communications and Knology, can be both an ILEC and a CLEC (see below) in different service areas.

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.
In Texas' deregulated energy market, customers must pick their own electricity provider, all of which offer different rates per hour of power usage. You can shop for other power plans on the state-run website,  www.powertochoose.org, or try an alternative website, like www.texaspowerguide.com to help find the cheapest plan. Keep in mind that many retail electricity contracts carry penalties for early termination.
Variable rate plans are always month-to-month, save for three-month intro specials in which your rate stays the same for those early months. Fixed rate plans, on the other hand, are available for periods ranging from six to 36 months. The contract lengths, and how that length influences the price per kWh rate, varies enormously from company to company. Some companies offer lower rates when you enroll for longer periods. Others raise the rate slightly. The competing rationale: You will be paying them for longer so you get a break, or you have that price locked in when energy rates inevitably rise. One rule of thumb — the longer the contract, the higher the cancellation fee.
In some deregulated markets, the local utility company can offer electric service at a standard service rate which is regulated by the state. In other deregulated markets, customers can receive electricity from a default electricity provider that may be related to their local utility. These are options for customers who don’t want to shop for an electricity plan and explore the possibility of a lower electricity bill.
Every state that is deregulated requires their electricity providers to be licensed or certified by the state in order to sell electricity. Your state’s public utility commission website keeps an up to date list of these electricity providers so that you can be certain that you are purchasing electricity from an authorized electricity provider. All of the electricity providers represented on ElectricityPlans.com are authorized electricity providers in the respective states where they do business.
If you’re looking for a new electricity deal, you’re not alone: 319,000 electricity customers switched energy supplier during January 2018, according to OFGEM*. Shopping around for the best electricity deal is simpler than you might think – but there are bound to be a few questions. Here’s everything you ever wanted to know about comparing electricity deals.
