Another positive environmental impact is the effect of higher energy prices on consumer choices, similar to the US market trend toward more fuel-efficient cars. As electric bills have risen, residents are reducing their electrical usage by using more moderate thermostat settings, installing insulation, installing solar screens, and other such activities. Texas utilities (such as Austin Energy) are also installing advanced electricity meters that may one day enable variable pricing based on the time of day. This would permit energy customers to save money by further tailoring their consumption based on whether it occurred during the peak demand period (high cost/high pollution) or the off-peak (night time).
Which ones the best? Like all things energy, it depends. Do you prefer predictability, or do you like the idea of potentially saving some cash by monitoring the market? Our (albeit conservative) recommendation: Fixed rate is probably best. Energy prices are on the rise — the U.S. Energy Information Administration predicts a 3 percent increase in residential electricity prices in 2018.

Since 2002, approximately 85% of commercial and industrial consumers have switched power providers at least once. Approximately 40% of residential consumers in deregulated areas have switched from the former incumbent provider to a competitive REP. REPs providing service in the state include: AmeriPower, TriEagle Energy, Acacia Energy, Ambit Energy,Breeze Energy, Clearview Energy, Green Mountain Energy, Conservice Energy, Iluminar Energy, Now Power, Snap Energy, Entrust Energy, Bounce Energy, Champion Energy, Shnye Energy, Cirro Energy, Direct Energy, Dynowatt, First Texas Energy Corporation, Frontier Utilities, Gexa Energy, Glacial Energy, Just Energy, Kinetic Energy, Mega Energy, APG&E, Adjacent Energy, Spark Energy, StarTex Power, Stream Energy, Tech Electricity, Texas Power, TXU Energy, XOOM Energy and 4Change Energy.

How does that work? Spark Energy buys electricity and competes in the market for the best price -- a competition that ultimately drives prices down and allows us to deliver more value for your money. In Texas, switching to a different electricity provider is kind of like changing to a different long distance company. When you switch to Spark Energy, the utility will continue to deliver electricity to your home but Spark Energy will handle all the billing, including the utility’s delivery fees and the electricity you actually use.
Fixed-rate supply plans offer price-protected supply rates for the length of a term agreement. The price per kilowatt hour (kWh) will remain the same throughout your term, even if the market price fluctuates. A fixed-rate supply plan can range from three months to five years, so it’s important to find the term length that works best for your situation.
According to a 2014 report[2] by the Texas Coalition for Affordable Power (TCAP), "deregulation cost Texans about $22 billion from 2002 to 2012. And residents in the deregulated market pay prices that are considerably higher than those who live in parts of the state that are still regulated. For example, TCAP found that the average consumer living in one of the areas that opted out of deregulation, such as Austin and San Antonio, paid $288 less in 2012 than consumers in the deregulated areas."
Not only does it show customers the real rates at different usage levels but it reflects both the rate jumps in a plan at certain usage. It also shows whether the rate is high or low compared to general electricity market pricing. By doing all the calculations for the customer, Texas Electricity Ratings' Rate Analyzer can show customers what their best energy options are when they shop for Texas electricity no matter what TDU area they are in. Customers can see how much they can really expect to pay each month for their usage.

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.
