As you choose your energy plan, you might want to consider a variable-rate plan. The wholesale price for electricity changes constantly and a variable rate allows you to take advantage of its ups and downs. When prices are low, your electricity rate can drop to reflect the market change. On the other hand, electricity prices can rise, causing you to pay a higher rate.
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.
