Why Houston's Electricity Market Is Different
Houston operates in a deregulated electricity market, which means you are not limited to a single utility. The local wires company, CenterPoint Energy, still delivers the power and maintains the infrastructure, but you can choose the Retail Electric Provider (REP) that generates your electricity and bills you each month. This choice is the core advantage of living or operating in the Houston area.

More than a dozen providers compete for customers in the Houston metro region, offering a mix of fixed-rate, variable-rate, and indexed plans. The Texas Coalition for Affordable Power and the Public Utility Commission of Texas (PUCT) oversee the market to ensure competitive pricing and transparent rules. Because providers frequently adjust their offers to match wholesale price swings, the best plan for your neighbor might not be the best plan for you.
Major Electric Providers Serving Houston
Several national and regional REPs actively serve Houston customers. Some focus on low introductory rates, while others emphasize renewable energy or customer service stability. The following are well-known providers with a presence in the Houston market: Constellation, TXU Energy, Reliant, Direct Energy, Gexa Energy, Cirro Energy, Amigo Energy, Champion Energy, and Payless Power. Many smaller providers also compete through aggregator websites, so the exact list of active offers changes often.
Each company offers multiple plan types. Fixed-rate plans lock in a cents-per-kilowatt-hour price for a contract term, typically ranging from two months to three years. Variable-rate plans float with the wholesale market, offering flexibility but exposing you to price spikes during peak demand. Indexed plans, such as those tied to the Houston Ship Channel or ERCOT's wholesale index, are a niche option best suited for customers who monitor the market closely.
What to Compare Before You Switch
Comparing electric providers in Houston requires looking beyond the headline rate. The Electricity Facts Label (EFL) for each plan, required by the PUCT, breaks down the rate structure, fees, and contract terms. Key items to compare include the base energy charge, the monthly minimum usage fee, TDU delivery charges (which are set by CenterPoint and cannot be changed by the REP), and any early cancellation fees.
Other factors matter for long-term satisfaction: contract length, whether the plan is green-certified, bill payment options, mobile app quality, and customer service availability. Some providers offer smart thermostat incentives or paperless billing discounts that can reduce your effective rate. If you run a business, check whether the provider offers demand response programs or time-of-use plans that shift heavy loads to off-peak hours.
Fixed vs. Variable vs. Indexed Plans
- Fixed-rate plans — predictable monthly bills, ideal for budget-conscious households and businesses.
- Variable-rate plans — no contract or short contracts, billing follows wholesale prices, can be cheaper in mild months but risky in summer peaks.
- Indexed plans — tied to an external index, more complex, best for sophisticated users who track market data.
How to Switch Providers Without Service Interruption
Switching electric providers in Houston does not require a technician visit or a service interruption. CenterPoint Energy continues to deliver power regardless of which REP you choose. To switch, you select a new provider, review and sign the plan agreement, and the new provider handles the enrollment with the ERCOT switching system. The process typically takes one to two billing cycles, and your lights stay on the entire time.
Start by reviewing your most recent bill to understand your average monthly usage in kilowatt-hours. A provider that offers a low rate for 1,000 kWh may not be the best fit if your household uses 2,000 kWh. Enter your zip code and usage profile on the PUCT's Power to Choose website or the provider's own site to see available plans and current rates.
Renewable and Green Options in Houston
Several Houston electric providers offer plans backed by renewable energy certificates or built around wind and solar generation. Gexa Energy, for example, has marketed 100% renewable plans, while others offer partial green options where a percentage of your usage is matched with renewable generation. If sustainability is a priority, look for plans certified under the Green-e Energy standard and review the EFL to confirm the renewable content percentage.
Tips for Avoiding Surprises on Your Bill
- Read the EFL for the exact rate at your typical usage level, not just the promotional rate.
- Watch for bill credits that require a minimum monthly usage or autopay enrollment.
- Set a calendar reminder when a fixed-rate contract ends so you can renegotiate or switch before the variable rate kicks in.
- Contact the provider directly if a bill looks unusually high — dispute processes exist under PUCT rules.
