TDSPs or EDUs are the companies and people who own and maintain utility poles and power lines. They are the ones that you call when your power goes out. These utility companies are responsible for the physical delivery of electricity to your home or business. Before deregulation, everyone was required to buy their electricity from their local utility company. With deregulation, the supply of electricity was opened to competition while the delivery of electricity continues to be regulated by the state’s public utility commission.
With moderate fluctuations taken into account, the variable plans is still cheaper. Our bill is approximately $10 more in the winter, but we’d still save $138 over the course of a year. It’s more a question of whether you can roll with the punches of an unpredictable rate, or would sleep easier knowing your bill is going to look the same month after month.
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.
