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.
Canadian electricity is cheap at 10 US cents per kilowatt hour, which is reflected in their high average electricity usage. US electricity prices at 0.12 $/kWh are also quite cheap internationally. In India and China they are very cheap. The UK is in the middle at 20 cents. It’s relatively expensive globally but not too bad for Europe, where most countries pay a high share of tax on their power.
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.
