Best Electricity Rates in Houston for March 2026

Last Updated: March 11, 2026

Houston electricity rates have entered their annual spring dip, with competitive fixed-rate plans now available from approximately 7.9¢/kWh in the CenterPoint Energy service territory. For the 2.5 million households and businesses in the Houston metro who can choose their electricity provider, spring 2026 is one of the best shopping windows in recent memory — and the window closes when summer heat arrives.

This guide compares the best Houston electricity rates available in March 2026, explains how CenterPoint's TDU delivery charges affect your total bill, identifies the top providers in the market, and helps you avoid common plan traps that inflate costs at high summer usage levels.

Executive Summary

Houston sits in Texas's deregulated electricity market, meaning you choose your retail electricity provider from dozens of competitors in the CenterPoint Energy delivery territory. As of March 2026:

• Lowest advertised energy rates: ~7.9¢/kWh (before TDU delivery charges)
• All-in rate at 1,000 kWh: approximately 12.2–12.5¢/kWh with TDU charges included
• Texas residential average (2025): 15.39¢/kWh per the EIA — Houston spring plans are significantly below this
• Average Houston usage: ~1,590 kWh/month (EIA/EnergySage data), making plan selection at high usage critical
• CenterPoint TDU charge: ~$4.39/month + 4.338¢/kWh (regulated; same across all providers)
• Best time to switch: Spring (March–May) — ERCOT demand is at its lowest, pulling rates down before summer spikes

The bottom line: if you're on an expired contract, a month-to-month rate, or a plan above 14¢/kWh all-in, switching now saves real money before summer temperatures drive both usage and rates to their annual peak.

Why March Is Houston's Best Month to Lock In Rates

Houston's electricity market follows a well-documented seasonal pattern. Spring mild weather drops ERCOT grid demand to its annual low, which puts downward pressure on wholesale electricity prices. Retail providers respond by launching their most aggressive fixed-rate plans to capture new customers before the summer rush.

Here's the seasonal pattern that drives Houston electricity pricing:

Winter (December–February): Moderate heating demand. Rates typically range from 11–14¢/kWh all-in for competitive plans. Less competitive than spring due to some residual demand.

Spring (March–May): Demand falls to annual lows. Providers compete for customers with spring plans. The best rates of the year are available — this is the window to act.

Summer (June–September): Houston's extreme heat pushes air conditioning loads to their peak. ERCOT wholesale prices can spike dramatically. Fixed-rate plans become harder to find, and variable-rate customers face bill shock. The average Houston household uses 2,000+ kWh in peak summer months.

Fall (October–November): A secondary window as cooling demand fades. Rates fall but typically not as low as spring.

The strategy: Lock in a 12- or 24-month fixed rate in spring. You'll carry a favorable rate through the expensive summer months without exposure to market price spikes.

How Houston Electricity Pricing Works

Before comparing plans, it's important to understand that your Houston electricity bill has two major components:

This is what your retail electricity provider charges for the energy itself. It's the rate you see advertised — "plans from 7.9¢/kWh." This component is competitive and varies significantly across providers.

CenterPoint Energy owns and maintains the poles, wires, transformers, and meters that deliver electricity to your home. These charges are set by the PUCT and apply identically regardless of which provider you choose. As of March 2026, CenterPoint's charges are approximately:

• Customer charge: $4.39/month (flat fee)
• Energy delivery charge: 4.338¢/kWh

For a household using 1,000 kWh/month, CenterPoint's TDU charges add approximately $47.77/month — or about 4.777¢/kWh equivalent. This means a "7.9¢/kWh energy plan" has an all-in cost of roughly 12.7¢/kWh at 1,000 kWh usage.

Important: Always compare plans using the total all-in cost from the Electricity Facts Label (EFL), not just the advertised energy rate. Some plans have bill credits that only apply at specific usage tiers, which can make a "cheap" plan expensive at your actual usage level.

Best Houston Electricity Providers: March 2026

Houston's deregulated market includes more than 50 retail electricity providers competing in CenterPoint territory. Here's an overview of the top options across different priorities.

Providers competing aggressively on price in spring 2026 typically include smaller regional REPs (Retail Electricity Providers) with lower overhead. Look for names like APG&E, Chariot Energy, Discount Power, and Cirro Energy at the low end of the rate spectrum. Energy-only rates for these providers in spring 2026 are available starting around 7.9–8.5¢/kWh for 12-month fixed plans.

What to verify: Check the EFL at 2,000 kWh, not just 1,000 kWh. Some low-rate plans include usage-tier credits ($50–$75/month credit at 1,000 kWh but zero credit at 2,000 kWh), which effectively make the plan more expensive for Houston's high-usage summers.

TXU Energy is Texas's largest retail electricity provider and consistently scores well for customer service reliability. TXU rates aren't always the lowest, typically running 1–2¢/kWh higher than budget providers, but their plan selection, customer support infrastructure, and reliability record make them a strong choice for customers who prioritize service over minimum cost.

Reliant Energy (NRG) is the second-largest provider in the Houston market and also scores highly for customer service. NRG offers a range of plan types including free nights and free mornings plans that can significantly reduce costs for households willing to shift usage.

Gexa Energy has built a reputation in the Texas market for transparent pricing and strong online account management. Gexa typically competes on rate with mid-range pricing and offers straightforward fixed-rate plans without complex usage-tier structures that trip up high-usage Houston households in summer.

Green Mountain Energy is a long-established Texas provider focused on renewable energy. Green Mountain plans typically run slightly higher than the cheapest conventional options but certify that your usage is matched by wind and solar energy certificates. For environmentally conscious Houston consumers, Green Mountain provides a credible renewable option without switching to a specialty or less-established provider.

For customers who prefer month-to-month flexibility or can't qualify for traditional contract plans, several providers including PayLess Power, Ambit Energy, and TriEagle Energy offer prepaid electricity in Houston. Prepaid plans carry no early termination fees but typically have higher rates than competitive fixed-rate plans. Spring is still the best time to lock in a prepaid plan — monthly variable rates reset with the market.

Understanding Houston's High Electricity Usage

Houston ranks among the highest electricity users in the United States. The average Houston household uses approximately 1,590 kWh per month (EnergySage, EIA data) — compared to the Texas average of ~1,132 kWh and the national average of ~899 kWh. This is not a coincidence.

Why Houston uses so much electricity:

• Extreme heat and humidity: Houston averages 106 days above 90°F per year. Air conditioning runs nearly continuously June through September.
• Older housing stock: Many Houston homes lack adequate insulation for the climate, increasing cooling loads.
• No natural gas alternatives for most loads: Unlike northern climates where gas handles heating, Houston's limited winter heating needs mean electricity dominates year-round.
• Sprawling development: Large single-family homes on large lots with high HVAC square footage are common.

This usage profile makes plan selection more consequential in Houston than in lower-usage markets. A 2¢/kWh difference at 1,590 kWh/month = $31.80/month, or $381/year. At summer peak usage of 2,200 kWh, the same 2¢/kWh gap costs $44/month.

Spring usage context: In March and April, Houston's mild weather means households typically use only 700–1,100 kWh/month. This makes spring a less expensive month for electricity bills regardless of your rate — but it's precisely the time to secure a favorable rate for the summer ahead.

How to Compare Houston Electricity Plans: Step-by-Step

Pull up your most recent CenterPoint energy bill. Your retail electricity provider's charge per kWh should appear separately from the TDU delivery charges. If you're on an expired contract or don't know your current rate, check your provider's website or call customer service.

Your current all-in cost per kWh = (total monthly bill − taxes and fees) ÷ kWh used. If you're paying above 14–15¢/kWh all-in, you have significant savings available by switching.

PowerToChoose is the official PUCT-sponsored electricity comparison site for Texas. Enter your ZIP code and average monthly kWh usage (find this on your current bill). The site shows all available plans with all-in pricing at your usage level.

Pro tip: Compare at both 1,000 kWh and 2,000 kWh. Houston summer usage frequently exceeds 2,000 kWh, and some plans that look cheapest at 1,000 kWh become expensive at higher usage due to usage-tier billing credit structures.

Every plan on PowerToChoose links to an EFL — a standardized one-page document that discloses the all-in rate at 500, 1,000, and 2,000 kWh usage. Read this before enrolling. Look for:

• Is the rate truly fixed or subject to pass-through adjustments?
• What is the early termination fee?
• Are there any hidden monthly fees?
• Does the rate include all charges except state/local taxes?

With ERCOT demand forecast to grow 14% in 2026 (EIA data, driven primarily by data center expansion) and natural gas prices projected higher for 2027, a 24-month plan locked in at spring 2026 rates offers more long-term protection. If you're confident you'll move in 12 months, a 12-month plan avoids early termination exposure.

CenterPoint TDU Rate Updates: March 2026

CenterPoint Energy updates its TDU delivery rates twice per year — in March and September — following PUCT approval. The March 2026 rates are effective as of the billing cycle beginning this month. As of the most recently filed rates:

• Residential customer charge: approximately $4.39/month
• Energy delivery charge: approximately 4.338¢/kWh
• Transition charges and other fees: vary by rate class

These charges appear as "CenterPoint Delivery" on your monthly bill, separate from your retail electricity provider's charges. They are non-negotiable and identical for all customers in CenterPoint's service territory regardless of provider choice.

For a typical 1,000 kWh month, TDU charges total approximately $47.77 — representing roughly 35–40% of a competitive plan's all-in bill at $120–$130/month.

Houston Electricity Bill Benchmarks: March 2026

Use these benchmarks to gauge where your current bill stands:

Note: "All-in" includes CenterPoint TDU charges plus estimated taxes/fees. Exact totals vary by plan structure.

If your current bill is tracking near the 15¢/kWh or 17¢/kWh columns, a switch to a competitive spring plan saves $40–$100/month at average usage and significantly more in summer.

When to Lock In vs. When to Wait

• Your current contract has expired and you're on a month-to-month variable rate (these can run 18–22¢/kWh or higher)
• Your fixed-rate contract expires within the next 60 days
• You're currently paying more than 14–15¢/kWh all-in at 1,000 kWh
• You prefer the certainty of knowing your rate before Houston's summer heating season begins

• You're in the middle of a competitive fixed-rate contract below 13¢/kWh with 6+ months remaining — honor the contract and shop when it expires
• Your current plan has a high early termination fee ($175–$250) that would wipe out near-term savings
• You're planning to move within 3–4 months — switching before a move often creates complications

Spring 2026 rates are favorable, but Texas electricity markets can be unpredictable. A significant spring weather event, unexpected grid stress, or natural gas price spike can shift market conditions quickly. If you find a competitive plan that meets your needs at a price that makes you comfortable, locking it in is generally better than waiting for a marginally cheaper option that may not materialize.
