No worries. It’s always a good idea to shop for a new electricity plan when you are moving to see if there is a better deal on electricity available. But, if you are happy with your current electric rate, most electricity providers will gladly keep you as a customer and continue service under your current contract at your new apartment or house as long as you move within the same utility delivery area. Don’t worry about early termination fees. If you are moving, your electricity provider cannot charge you an early termination fee if you provide a valid proof of a change of address thanks to customer protection rules established by the Public Utility Commission of Texas.
As of April 2014, 16 U.S. states and the District of Columbia have deregulated electricity markets. Along with aforementioned Maryland and Texas, electricity deregulation is current in Connecticut, Delaware, Illinois, Maine, Massachusetts, Michigan, Montana, New Hampshire, New Jersey, New York, Ohio, Oregon, Pennsylvania, and Rhode Island. Seven additional U.S. states began the process of electricity deregulation but have suspended efforts: Arizona, Arkansas, California, Nevada, New Mexico, Virginia, and Wyoming.
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.

It all starts with the power generators – the companies who produce electricity to sell on the wholesale market. The electricity providers purchase the rights to large volumes of this electricity from the generators on the wholesale market and then turn around and sell it to their retail customers. The electricity providers market the sale of electricity to the public through various offerings of electricity plans that include everything from classic fixed-rate electricity, to 100% green electricity, to bundled products that have incentives such as a Nest Learning Thermostat™ or Visa gift cards.
On the one hand, long-term, fixed-rate (contract) plans offer stability in pricing. If energy supply costs suddenly go up in your area, you won’t be left paying more than what you bargained for. You’ll have peace-of-mind. If you want to switch out of your contract before it ends with a lower cost plan, you’ll likely face a cancellation fee (early termination fee).
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.
Depending on the state where you live, you’ll get your electricity bill from your local electric utility or your electricity provider. Either way your electricity bill generally has two line items: supply and delivery. The supply charge is for the actual electricity used and this is paid to your electricity provider. The delivery charge is for the transmission and distribution of electricity and this is paid to your local electric utility. In most states you will receive these charges on one bill, and the company that collects your payment will make sure that the appropriate parties are paid for their services.
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.
