But competition didn't necessarily end up cutting prices, according to the report. One contributing factor is confusion among customers as they try to choose among scores of retail electricity providers and the overwhelming variation of plans, leading many to just stick with familiar companies rather than look for better deals, according to the Texas Coalition for Affordable Power .
1. After your contract ends, the energy company will send you a notification of your rate increasing to a variable rate (which usually translates to 2-3 cents higher/kWh by a certain date). They are supposed to notify you of this change. I've noticed as a customer, we get short-changed of one month from the contract rate (if you signed for 7 cents for 6 months, you'll only get that for 5 months). If you don't call, your rate goes up significantly if you don't call to change to a cheaper contract. Tell them you want the cheapest rate or you will cancel with their company.
The threat of price spikes have been long in the making, the result of changing economics of power production. The shale drilling boom produced record amounts of natural gas, which pushed prices to all-time lows and made gas-fired plants cheaper to operate than coal. Renewable energy such as wind is also producing abundant amounts of electricity at a lower cost than coal.
After spending so much time and energy with energy companies, I figure I should pass this info onto the internet world (within Houston). I am a Centerpoint Energy resident (you don't get to choose the electricity provider you have; it's based on where the electricity is provided). I think Houston is predominantly a Centerpoint energy area (correct me if I'm wrong).

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.
2. Most companies have this basic $9.95/mo charge if you don't meet a certain kWh, usually 1000 kWh (Reliant is 800kWh minimum). That will pose a problem in those more temperate months like in the spring and fall because although you're paying lower kWh,you're paying that extra $9.95/mo for no reason. ASK YOUR ENERGY PROVIDER WHAT THE LIMIT IS. I got a minimum of 800kWh/mo with Reliant; if I go under 800kWh, I will have to pay $9.95. Good thing about Reliant is that they do a weekly energy usage report, and you can keep up with how much you may owe. That's pretty useful to me, considering I live in a smaller space, thus less usage.
You can sort, filter, and shop by pricing at YOUR specific usage level, which lets you shop and compare electricity plans based on the rates you’ll actually experience on your bill, inclusive of hidden fees and taxes. This ensures you’re not misled by the cheaper rates often advertised by electric providers…those “teaser rates” associated with higher usage levels that many households never enjoy because their usage level never reaches that pricing tier.
