More on the energy market in Texas: Customers in Texas have options in how they are billed for their electricity, according to the Public Utility Commission of Texas' (PUCT) website. If you go with a fixed plan, your price for electricity is fixed and doesn't fluctuate with the market. However, there are also market rate plans that are tied directly to the price utility companies pay for electricity. Their website touts that customers "pay exactly the price we buy electricity at" and that their model "beats the [Texas] average 96% of the time." When the winter storm wreaked havoc on Texas' power grid, power prices shot up and so did bills for customers on market rate plans.
