If you decide to switch, you won’t be charged an exit fee.

“The whole business model of the industry is to get people in on the promotional rates and then jack up their rate when the promotional rates end,” said Trent Crow, a former JP Morgan energy trader and founder of Real Simple Energy, a website that helps consumers find low-cost electricity plans. “I don’t think people realize how much they are overpaying.”
