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.

TXU is high because they charge their customers for the "fuel" to run their power plants - that's what the supervisor told us when we called to complain about my godmother's bill. Her actual usuage was $350 and they charged her an additional $350. And she didn't understand the bill so she had been paying it for months until we started looking at it. They are a rip off. Would never recommend them.
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.
As a result, power companies have shut down Texas coal plants unable to compete with lower-cost generators. Meanwhile, the low electricity prices of recent years — a function of cheap natural gas — and small profits have discouraged companies from investing in new power plants. ERCOT, which oversees about 90 percent of the state’s power grid, said power reserves that are called on when demand peaks on the hottest summer days have shrunk to the lowest levels since Texas deregulated power markets in 2002.
Canadian electricity is cheap at 10 US cents per kilowatt hour, which is reflected in their high average electricity usage. US electricity prices at 0.12 $/kWh are also quite cheap internationally. In India and China they are very cheap. The UK is in the middle at 20 cents. It’s relatively expensive globally but not too bad for Europe, where most countries pay a high share of tax on their power.
Partha Krishnamurthy, a marketing professor at the University of Houston, said he suspects that many people may be unaware they’re paying more than they need to for electricity, putting their bills on autopay and forgetting about the rates they pay. Most people don’t go to the trouble of changing banks, jobs or their electricity providers, for that matter, unless there are problems.
With over 2.3 million residents, Houston is the largest city in Texas and the fourth most populated in the United States. Encompassing over six hundred square miles, Houston stands as the fifth most popular metropolitan area in the country and gets its name from the commander who won Texas’ independence from Mexico in 1836. The city lies in the southeastern portion of the state within a deregulated Electricity market and as such, allows residents to select an energy provider from the various service companies that serve the state.
