Fixed-rate, long-term (contract) plans provide stability in electricity rates. If market energy costs suddenly trend upward where you live, you can rest assured that you won’t have to pay more out of pocket. However, if you want to switch to a different, lower-cost plan before the end of the contract term, you’ll likely have to pay a cancellation or early termination fee.
You can organize and shop by pricing at YOUR individual usage level, which allows you to shop and compare energy plans based on the rates you’ll actually see appear on your bill, inclusive of taxes and hidden fees. You won’t be misled by the “teaser rates” tied with higher usage levels that many homes never experience, as their usage level never reaches that pricing tier.
Aside from times of natural disasters and large-scale accidents, electricity prices tend to be steadily dictated by electricity demand. Typically, the price of electricity rises when demand rises. In turn, the lower demand is, the cheaper electricity rates become. This pattern is due to the fact that increased demand requires increased energy production. When extra energy is demanded, utilities are forced to use alternative sources of energy production that may cost more to operate. For example, when electricity demand reaches a high point in Texas, coal plants are used alongside the typical natural gas plants. These coal plants are costlier and less effective than natural gas plants, but are necessary to meet high electricity demand levels.[1]

The inclusion of renewable energy distributed generation and AMI in the modern electricity grid has introduced many alternative rate structures. Simple (or fixed) rate, tiered (or step) rate, TOU, demand rates, tiered within TOU, seasonal, and weekend/holiday rates are among the few residential rate structures offered by modern utilities. The simple rate charges a specific dollar per kilowatt ($/kWh) consumed. The tiered rate is one of the more common residential rate programs, and it charges a higher rate as customer usage increases. TOU and demand rates are structured to help maintain/control a utility’s peak demand. The concept at its core is to discourage customers from contributing to peak-load times by charging them more money to use power at that time.

The comparison does not take into account factors including fluctuating international exchange rates, a country's purchasing power, government electricity subsidies or retail discounts that are often available in deregulated electricity markets.[5]

Even though customers in deregulated Texas markets routinely pay more for electricity, there is a bright spot. The gap between the average price paid for electricity between deregulated and regulated market has shrunk to 8.8 percent. In 2006, customers in deregulated cities were paying nearly 47 percent more for electricity than their counterparts in regulated cities.
