Usually, fixed-rate renewable-energy plans are among the most expensive options. But in our research, we found Constellation’s green plan rates were comparable to its non-green versions. For example, out of two otherwise identical fixed-rate, 12-month plans from Constellation — “12 Month Fixed Rate 100% Green” and “12 Month Fixed Rate” — it’s the renewable version that currently costs less.
Should you choose a short-term, long-term, month-to-month, or prepaid plan? The short answer: it depends on your specific needs. How long do you anticipate living at your location? Are you deciding in the peak season (summer in Houston) or off season? All electricity providers in Houston offer a broad selection of plans for different contract lengths. Many also offer month-to-month and prepaid electricity plans. The bottom line is that everyone’s needs are different and all contract term lengths offer advantages and disadvantages.
No. When you’ve chosen a new deal, your new supplier will handle the switching process. They’ll contact you to let you know what date you’ll be transferred over, and they’ll contact you around the switching date to ask for a meter reading. They’ll pass this on to your old supplier so they can send you a final bill. You don’t need to contact your old supplier, as the new supplier will handle everything for you.

To our surprise, the results were all over the board. Green plans weren’t always more expensive than their traditional counterparts. Sometimes a fluctuating variable rate is still cheaper in the long run. Our takeaway: It pays to shop around. We’ll walk you through our analysis — so you can do the same as you compare rates.


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.
Keeping on top:  With deregulation, a whole host of electric resellers jumped into the market because there’s a whole lot of electricity to sell:  if Texas were a country, it’d be the 11th largest electricity consumer in the world!  Just by itself, it uses as much electricity as Spain or Great Britain!  That means there’s a whole lot of information you have to find, absorb, and process to make sure you’re getting the best rate for your needs.

Since the 1990s, many regions have opened up the generation and distribution of electric power to provide a more competitive electricity market. While such markets can be abusively manipulated with consequent adverse price and reliability impact to consumers, generally competitive production of electrical energy leads to worthwhile improvements in efficiency. However, transmission and distribution are harder problems since returns on investment are not as easy to find.
