On the one hand, long-term, fixed-rate (contract) plans offer stability in pricing. If energy supply costs suddenly go up in your area, you won’t be left paying more than what you bargained for. You’ll have peace-of-mind. If you want to switch out of your contract before it ends with a lower cost plan, you’ll likely face a cancellation fee (early termination fee).
Another unwelcome side effect of not knowing your average monthly kWh usage level is that you may end up paying more than you expect. This can occur when a customer inadvertently shops an electric rate based on a higher usage level than they actually use. Electricity suppliers commonly advertise their electric rates associated with the highest (2000 kWh) usage levels since those tend to be the lowest rates.
Then, in 2002, Texas deregulated the electricity market and everybody cheered! Except that, sure, deregulation opened up the market to competition that may (or may not) have resulted in lower rates, but it introduced a whole host of other issues. These issues may not have been factors before but now they’re critical when you’re on the look-out for cheap Houston electricity providers.
