Which ones the best? Like all things energy, it depends. Do you prefer predictability, or do you like the idea of potentially saving some cash by monitoring the market? Our (albeit conservative) recommendation: Fixed rate is probably best. Energy prices are on the rise — the U.S. Energy Information Administration predicts a 3 percent increase in residential electricity prices in 2018.
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.
Fixed-rate, long-term (contract) plans provide stability in electricity rates. If market energy costs suddenly trend upward where you live, you can rest assured that you won’t have to pay more out of pocket. However, if you want to switch to a different, lower-cost plan before the end of the contract term, you’ll likely have to pay a cancellation or early termination fee.
