These rates are practically the opposite of fixed rate plans. As opposed to fixed-rate plans, variable rates are a better option for people living in an apartment or house for a short term. With a variable energy rate, our customers are free from a long-term contract, and they can pay the market price. This enables our customers to take advantage of price drops when the market fluctuates. The downside, however, is that when energy rates spike, so will your electricity bill. This option is a good one for risk-takers. You will be able to benefit from energy rate decreases while risking a rise in energy prices.
That phenomenon has played out in Texas electricity markets, where few customers are willing to navigate the maze of power plans in the hope of shaving a few cents per kilowatt hour from their electric rates, according to the Texas Coalition for Affordable Power which buys electricity on behalf of municipal governments in Texas. As result, customers in regulated markets such as San Antonio and Austin on average pay less for electricity than those in deregulated markets like Houston, according to the coalition.

Likewise, if you opt for a plan like our StarTex Power example, but in some months only hit 990 kWh of energy use, the $35 discount for cresting $1,000 kWh won't apply — and your bill is going to show it. Picking the right plan for you requires two things: an intimate knowledge of your home’s typical energy use, and a critical eye on any plan’s fine print.

REPs sell electricity rates to Houston energy consumers, but transmission and distribution service providers (TDSPs) deliver the supply of electricity. In Houston, CenterPoint Energy serves as the area's TDSP and works with about 85 REPs. If your power goes out, immediately report the issue to CenterPoint Energy, not your REP. Use the following phone numbers to get in touch with your Houston TDSP.
