Best Electricity Rates in Houston, TX (2026): Compare Plans by ZIP Code

Houston has more electricity provider choices than almost any city in the United States. CenterPoint Energy delivers power through the lines, but you choose which retail electricity provider (REP) supplies your electricity — and the rate differences between providers can be substantial. In 2026, Houston residential rates range from under 10 cents per kWh on promotional plans to over 18 cents on month-to-month variable plans. The right plan depends on your usage level, CenterPoint TDU zone, and risk tolerance for rate volatility.

Houston Electricity Market: What You Need to Know

Houston sits in the CenterPoint Energy service territory within the ERCOT (Electric Reliability Council of Texas) deregulated grid. CenterPoint handles the physical poles-and-wires delivery of your electricity — you pay CenterPoint a monthly TDU (Transmission and Distribution Utility) delivery charge regardless of which retail provider you choose. That TDU charge runs approximately $30–$40 per month for a typical Houston household and appears as a separate line item on your bill.

The retail electricity provider you choose determines your energy charge (the cents-per-kWh rate on the energy you actually consume). Choosing the right provider can save $300–$800 per year on a typical Houston electric bill.

Houston Electricity Rates in 2026

Electricity rates in Houston fluctuate based on ERCOT wholesale prices, natural gas prices, and seasonal demand. In 2026, benchmark rates for a 12-month fixed-rate plan in the CenterPoint territory are running in these ranges for a household consuming 1,000 kWh/month:

Plan Type	Typical Rate Range (all-in)	Best For
12-month fixed	11–15¢/kWh	Most households — rate stability for a year
24-month fixed	12–16¢/kWh	Rate lock during rising market periods
Free nights/weekends	14–18¢/kWh daytime (off-peak “free”)	Households flexible to shift usage to evenings/weekends
Month-to-month variable	9–22¢/kWh (market-dependent)	Short-term flexibility; high volatility risk
Prepaid (no deposit)	13–18¢/kWh	No credit check required; pay as you go

Rates shown are estimates for CenterPoint territory at 1,000 kWh/month. Actual rates vary by ZIP code, provider, and market conditions. Always check the Electricity Facts Label (EFL) for your specific plan.

Top Electricity Providers Serving Houston in 2026

Over 60 retail electricity providers are licensed to serve the Houston/CenterPoint territory. The largest by market share include TXU Energy, Reliant Energy, Gexa Energy, Pulse Power, Frontier Utilities, Green Mountain Energy, Direct Energy, and Constellation Energy. Smaller providers like 4Change Energy and Payless Power also operate in Houston and frequently offer competitive rates on targeted plan structures.

The most competitive rates in Houston are rarely from the largest providers — Gexa Energy, Pulse Power, and Frontier Utilities consistently appear near the top of rate comparison tools for CenterPoint territory fixed-rate plans. That said, the lowest-rate plan isn’t always the best choice if the provider has poor customer service ratings or unexpected fees buried in the EFL.

How to Find the Best Houston Electricity Rate for Your ZIP Code

Houston ZIP codes fall within different CenterPoint subzones, and rates can vary by 1–3 cents per kWh between ZIP codes even within the same city. The only way to see your actual rate options is to enter your specific ZIP code into a comparison tool.

When comparing plans, look at the Electricity Facts Label (EFL) for each plan — this is the standardized disclosure document Texas requires all providers to publish. The EFL shows the exact average price per kWh at 500, 1,000, and 2,000 kWh monthly usage levels. Always compare at the usage tier closest to your actual average — a plan with a great 1,000 kWh rate may be expensive at 500 kWh if it has a usage credit that doesn’t kick in below 1,000.

Houston Electricity: Seasonal Rate Patterns

Houston’s electricity market is highly seasonal. Summer months (June–September) drive the highest ERCOT wholesale prices due to air conditioning demand — Texas summers push statewide demand to near-record levels, raising spot prices and making variable-rate plans especially risky in those months. Winter prices are generally lower except during extreme cold events (the February 2021 Winter Storm Uri being the most dramatic example, when spot prices spiked to the ERCOT cap of $9,000/MWh).

The practical implication: locking in a 12-month fixed-rate contract in late fall or winter (October–January), when wholesale prices are typically lower and providers are offering competitive rates to fill contract books before summer, often produces the best annual rate. Renewing or starting a new contract in July or August when summer demand is peak tends to produce higher locked rates.

TDU Charges and Your Houston Electric Bill

Your Houston electric bill has two main components: the energy charge (set by your retail provider) and the TDU delivery charge (set by CenterPoint). CenterPoint’s delivery charge in 2026 includes a customer charge (~$6.75/month), a distribution charge (~1.3¢/kWh), and various pass-through charges for transmission, distribution system improvements, and ERCOT. All-in, CenterPoint TDU charges add approximately $30–$40 per month to a typical household’s bill regardless of which provider you choose.

When comparing providers, the rate shown in comparison tools is typically the all-in cost including the TDU passthrough — but always verify on the EFL. Some providers show their energy-only rate (excluding TDU) in their marketing, which understates your actual total bill.

Switching Electricity Providers in Houston

Switching providers in Houston is straightforward. Your electricity service is never interrupted — CenterPoint continues to deliver power through the same lines. The switch typically takes effect within 1–2 billing cycles. If you’re within a contract term, check your ETF before switching; if you’re month-to-month or at contract end, switching is free.
