That means that customers in Houston paid an average of $5,500 more for electricity over a 14-year time span beginning in 2002, according to the group that buys electricity on behalf of municipal governments in Texas. The calculation, which uses data from the U.S. Energy Information Administration, assumes monthly electricity use of 1,300 kilowatt hours.
Texas deregulated most of the state's electricity markets in 2002, a move aimed at lowering electricity costs by letting consumers choose their own electric power providers and their own plans. Some parts of Texas continued to be regulated, including those that get power from municipal utilities, electric cooperatives and investor-owned utilities that operate outside the state's primary power grid.

Still, we like that if you choose to re-up with FirstEnergy again at the end of your initial term, you won’t have to worry whether you’re enrolling at an expensive time of year. First, since it offers just two options, constant for years, its prices are set with the long haul in mind. Second, since the electricity grid in Pennsylvania is more taxed during winter than any other season (space heating accounts for 50 percent of household electricity consumption in PA; air conditioning just three percent), signing up in summer means prices won’t be temporarily inflated.

In Pennsylvania, you can choose from the EGSs operating in your area, or stay on with your default provider — your EDC. Currently, less than half of all Pennsylvania’s residential customers have made the switch. If you’re among that number, moving to an EGS could get you cheaper rates, better rewards, and more say in what fuels generate your electricity. Whichever you choose, your electricity will get to you just the same because the EDC is always responsible for delivery.
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.
