Variable-rate supply plans, as the name suggests, have a rate that varies based on the market price of electricity. Seasonal and market fluctuations can affect supply rates. While variable-rate supply plans can allow you to take advantage of market-price lows, there is the possibility of paying for high supply rates when demand is at its peak. These plans offer great flexibility.
The price difference may be a few cents, but another Texas electricity company might offer better rewards, have better customer service, or may offer other plans you may be interested in the future. Some plans may draw you in with a low promotional rate, but once that promotional period is up you may be faced with a high rate. Be sure to read all the fine print when it comes to your electricity plan selection.
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.
