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.
On the other hand, month-to-month variable rate (no-contract) plans don’t have cancellation fees. You won’t be penalized if you find a better deal elsewhere and want to make another switch.  And, you won’t be stuck paying more than you should be if the market rate for electricity trends down.  But, if it goes up, you’ll be paying more than your in-contract neighbors, and you’ll likely want to shop around again for a better deal.
