In the Houston area, only 16 percent of CenterPoint Energy’s 2.4 million residential customers — or about one in six — switched their electricity providers over the past year, according to the state’s grid manager, the Electric Reliability Council of Texas. Among the 3.5 million customers of the state’s largest electric distribution utility, Oncor of Dallas, just 13 percent — only one in eight — signed up with a new retail power company in the last 12 months.
The cheapest rates are going to have shorter contract terms. For instance, a 3 month term is cheaper than a 6 month term and a 6 month term is cheaper than a 12-14 month term. So if you are able to remember to call before your contract expires (they will notify via mail you that your contract is about to expire), then the 3 or 6-month term is your best bet. If you don't call to renew/cancel, you will be charged a much higher variable rate on a month-to-month basis. If this is you, sign for a 12-month contract term with the cheapest rate.
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).
