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.
For example, if you use a small amount of energy each month, you expect to be rewarded — right? Unfortunately, nearly all electricity plans from Texas REPs are advertised as costing more per kWh the less electricity you use. It’s a little like buying in bulk: Providers often discount your bill when you cross certain kWh thresholds. For instance, one 12-month plan from StarTex Power quotes 8.1 cents per kWh for 1,000 kWh a month and 8.8 cents for 2,000 kWh per month, but 12.1 cents for 500 kWh per month. Why the difference? Customers get $35 back each month if they pass 1,000 kWh of use, and another $15 back per month if they cross 2,000 kWh. In this case, using half as much electricity as your neighbor on the same plan wouldn’t get you half the bill.
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.
