Shopping for electricity in the greater Houston area is notoriously complicated. As the largest deregulated energy market in Texas, Houstonians are inundated with hundreds of plans from dozens of retail electric providers, each promising the "cheapest rate in town."
Yet every summer, thousands of Houston residents open their electricity bills to discover costs of $400, $500, or even $600—despite enrolling in what appeared to be an inexpensive plan.
Why does this happen? The Houston climate creates unique energy demands, retail electric providers use sophisticated pricing gimmicks to game rate comparison websites, and utility delivery charges add a substantial non-negotiable fee to every kilowatt-hour you consume.
This guide provides an objective, step-by-step roadmap to shopping for electricity in Houston, helping you avoid teaser rate traps and find the lowest true out-of-pocket cost for your home.
To shop for electricity in Houston, compare 12-month to 36-month fixed-rate plans based on your actual monthly kilowatt-hour (kWh) usage rather than the advertised 1,000 kWh teaser rate. Greater Houston residents pay two separate charges: an energy supply charge to their chosen Retail Electric Provider (REP) and a regulated delivery charge to CenterPoint Energy ($4.39/month + ~5.46¢/kWh). Avoid tiered plans, minimum usage fees, and variable holdover rates.
How the Houston Electricity Market Works
In Houston, your monthly electric bill is split into two separate components governed by the Electric Reliability Council of Texas (ERCOT):
- Your Retail Electric Provider (REP): Companies like Reliant, TXU Energy, Gexa, Discount Power, and Champion Energy buy wholesale electricity and sell retail plans to consumers. You have complete freedom to select your provider based on price, contract length, and customer service.
- Your Transmission and Distribution Utility (TDU): In the vast majority of greater Houston (including Pasadena, Katy, Cypress, Sugar Land, Spring, The Woodlands, and Pearland), your physical utility is CenterPoint Energy. CenterPoint owns the poles, high-voltage wires, transformers, and digital smart meters. (Certain coastal areas in Galveston County, such as League City and Dickinson, are served by TNMP).
Under regulations set by the Public Utility Commission of Texas (PUCT), retail providers pass through CenterPoint delivery charges directly to your invoice with zero markup.
In 2026, CenterPoint charges a flat $4.39 monthly customer fee plus ~5.46¢ per kWh delivered. Regardless of which provider you choose, these delivery charges remain identical.
The Houston Climate Factor: Extreme Seasonal Usage Swings
Houston’s subtropical climate and heavy humidity mean that central air conditioning is not a luxury—it is a vital necessity from April through October.
This creates an intense seasonal consumption curve that differs sharply from other parts of the country:
- Mild Spring/Autumn (April, November): 600 to 900 kWh per month.
- Peak Summer (July, August, September): 1,800 to 2,800 kWh per month for a typical 3-bedroom single-family home.
Because Houston electricity usage swings by 200% to 300% between seasons, static comparison tools that only display rates at a flat 1,000 kWh benchmark can cost you hundreds of dollars.
The "So What?" Math Bridge: Real Houston Bill Calculations
To see how supply rates and CenterPoint delivery charges interact across seasons, examine the real-world bills for a typical 2,000-square-foot Houston home on an honest, fixed-rate plan with an 11.2¢ energy supply rate.
Scenario A: Mild Spring Billing Cycle (800 kWh Consumed)
- Base Energy Supply Charge (800 kWh x 11.2¢): $89.60
- CenterPoint Flat Customer Charge: $4.39
- CenterPoint Delivery Charge (800 kWh x 5.46¢): $43.68
- Total CenterPoint Delivery Costs: $48.07
- Total Monthly Electricity Bill: $137.67
- Effective Average Price per kWh: 17.21¢
Scenario B: Peak Summer Cooling Cycle (2,200 kWh Consumed)
- Base Energy Supply Charge (2,200 kWh x 11.2¢): $246.40
- CenterPoint Flat Customer Charge: $4.39
- CenterPoint Delivery Charge (2,200 kWh x 5.46¢): $120.12
- Total CenterPoint Delivery Costs: $124.51
- Total Monthly Electricity Bill: $370.91
- Effective Average Price per kWh: 16.86¢
Notice that CenterPoint delivery fees alone exceed $124.00 during peak summer months. If this homeowner had enrolled in an unhedged variable plan where the base energy rate spiked to 19¢ during heat waves, their summer bill would have skyrocketed past $540.00.
Common Plan Types in Houston: The Pros and Pitfalls
| Plan Structure | How It Works | The Advantage | The Hidden Risk |
|---|---|---|---|
| Fixed-Rate Plans | Locks in your energy supply rate for 12, 24, or 36 months. | Complete budget stability; immune to ERCOT wholesale price spikes. | Early termination fee if you cancel early (unless moving). |
| Variable / Month-to-Month | Rate changes every month at provider discretion. | No long-term contract or cancellation fees. | Extreme summer rate spikes (rates often exceed 25¢/kWh). |
| Bill Credit Gimmick Plans | Offers a $50–$100 credit if monthly usage hits exactly 1,000–1,500 kWh. | Advertises ultra-low rates at precisely 1,000 kWh on comparison sites. | Forfeits the entire credit if usage is 990 kWh in spring or 1,600 kWh in summer. |
| Free Nights & Weekends | Free power from 9 PM to 6 AM, but charges 18¢–22¢ during the daytime. | Great if you can shift $>60%$ of usage to overnight hours (EV charging). | Daytime Houston A/C usage during 100°F afternoons produces massive bills. |
| Prepaid Electricity | Pay-as-you-go with no deposit or credit check. | Immediate power connection with low upfront cost. | Effective rates are 20%–40% higher than standard fixed contracts. |
5 Essential Rules for Shopping in Houston
1. Never Shop Based on Advertised 1,000 kWh Teaser Rates
Comparison portals allow providers to highlight plans that look cheap at exactly 1,000 kWh. In Houston, you will rarely consume exactly 1,000 kWh. Look for plans with a flat energy charge across all consumption tiers rather than plans that require hitting a tight target to receive a discount.
2. Scrutinize the Electricity Facts Label (EFL)
Before completing enrollment, download the official Electricity Facts Label (EFL) PDF. Check the Base Charge line item. If you see conditional language—such as a $9.95 fee if usage is under 1,000 kWh—look elsewhere. Read our in-depth guide on The Minimum Usage Fee Trap to learn how to identify these penalties.
3. Factor in CenterPoint Delivery Charges
Remember that the energy rate quoted by your provider does not include CenterPoint’s delivery charges (~5.46¢/kWh + $4.39/month). Review our comprehensive CenterPoint TDU Delivery Charges Breakdown to see how delivery fees impact bills in Houston, Katy, and Sugar Land.
4. Leverage the 14-Day Free Switch Window
If you are currently under contract with a provider in Houston, you do not have to wait until the final day to switch. Under PUCT rules, you can switch penalty-free up to 14 days before your contract terminates. Review our guide on the PUCT 14-Day Switch Rule to time your transition perfectly.
5. Shop Based on Your Actual 12-Month Usage History
The single most effective way to save money on Houston electricity is to model plans against your actual historical consumption from Smart Meter Texas. Analyzing your seasonal usage highs and lows prevents you from signing a plan that looks cheap on paper but penalizes you in real life.
