According to a typical economic theory, prices are optimally determined in a fair and transparent market, and not by a political or academic body. In deregulation of electricity markets, one immediate concern with pricing is that incumbent electricity providers would undercut the prices of new entrants, preventing competition and perpetuating the existing monopoly of providers. Thus, the SB7 bill introduced a phase-in period during which a price floor would be established (for incumbent electricity companies) to prevent this predatory practice, allowing new market entrants to become established. New market entrants could charge a price below the price to beat, but incumbents could not. This period was to last from 2002 to January 1, 2007. As of 2007 Texas investor owned utility affiliates no longer have price to beat tariffs.[6]

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.

Fixed-Rate plan: With a fixed-rate plan, you’ll lock in an electricity rate for the term of your contract. The most common term lengths are six ,12, and 24 months. Most fixed-rate plans charge customers an early termination fee if they switch providers before their contract expires, but your electricity rate will stay stable through the seasons. On the other hand, you may miss out on lower bills from a downturn in energy prices. If the price stability of a fixed-rate plan seems like the best option for you, lock in your electricity rate with Compare Electricity Rates’sFree Weekends plan, which provides free electricity on weekends from 6 p.m. on Friday to 11:59 p.m. on Sunday.
Despite the fact that Texas sees much higher temperatures year round, most households contain and use heating units. These units generate heat in one of four ways: other, propane, electricity and natural gas. Switch Energy over half of households in Texas use electricity to run their heating units. This is a much greater average than the overall average for the nation.

The growth in wind power and natural gas fueled power will offset the loss in coal over time but for the summer of 2018, expected record demand for electricity will converge with power plant closures to put a squeeze on wholesale electricity rates. This, in turn, will cause the retail electricity prices paid by most Texas consumers to increase. The rise in wholesale rates could be particularly dangerous for consumers who have electricity plans that are tied directly to the wholesale price of electricity.
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.
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.
