According to the U.S. Energy Information Administration, the average household in Texas uses about 15,000 kWh of electricity per year — 26 percent more than the national average, “but similar to the amount used in neighboring states.” That said, the only way to know your personal average energy consumption is by looking at your electricity bills over the course of a year (you want to accommodate all weather conditions) and understanding both your overall usage, as well as if you use more or less during certain months.
Month-to-month electric plans are more commonly known as variable rate plans. With these plans the amount you pay per kilowatt-hour for your electricity each month will vary. This price is based on fluctuations in the market, so when the price of electricity falls you’ll pay less, but when it rises, you’ll pay more. In other words, you’re really gambling and should realize ahead of time that what you pay for your electric will change every month. This is why month-to-month electricity plans are only best for people who need electricity for a short amount of time.
In this free market competing electricity retailers buy electricity wholesale from private power generators to sell at retail to around 85% of Texas residents. The partnership between generators and retailers is governed by the Electric Reliability Council of Texas, or ERCOT, which attempts to balance the power grid’s electricity supply and demand by purchasing small amounts of electricity at 15-minute intervals throughout the day.
