Best Electricity Rates in Dallas, TX: March 2026 Complete Guide

Last Updated: March 12, 2026

Dallas has one of the most competitive electricity markets in the country. As a fully deregulated city in Oncor Electric Delivery territory, every Dallas resident can choose their electricity provider — and right now, in March 2026, is the best time of year to do it.

Spring demand is low. Retail electricity providers (REPs) are competing hard for new customers before summer heat sends rates climbing. Fixed-rate plans are running 2–4¢/kWh below what they were in summer 2025, and locking in a 12-month contract now protects you through the peak of Dallas's brutal July–August cooling season.

This guide gives you the numbers you need: current rates by tier, Oncor delivery charges, all-in bill estimates, and a clear framework for choosing the right plan.

How Dallas Electricity Works: Two Bills, One Delivery System

Every Dallas electric bill has two components that are billed together but operated by separate entities:

1. Oncor Electric Delivery (the wires company) Oncor owns and maintains the power lines, transformers, meters, and grid infrastructure in Dallas. Oncor is regulated by the Public Utility Commission of Texas (PUCT). Its charges are the same regardless of which REP you choose — you cannot negotiate them away.

2. Your Retail Electricity Provider (REP) The REP is the company you choose. They buy electricity on the wholesale market, add a margin, and bill you. REPs compete on price, contract terms, renewable content, and customer service. Switching REPs is free and does not interrupt power delivery — Oncor still runs the lines.

This structure is what makes Dallas deregulation work. Oncor's delivery charges are fixed and predictable; your REP's energy charge is where you save money by shopping.

Oncor Delivery Charges: March 2026

Understanding Oncor's fees is essential for comparing Dallas electricity plans accurately. These charges appear on every Dallas electric bill:

At typical usage levels, Oncor charges account for roughly 35–40% of your total Dallas electric bill. This is why a plan advertised at 9¢/kWh energy-only costs you more like 14¢/kWh all-in — the Oncor delivery component (5¢/kWh + ~$4.50/kWh amortized monthly charge) adds about 5.5¢ to every kWh you use.

PowerToChoose.org displays rates at 500, 1,000, and 2,000 kWh. These are all-in rates that include Oncor delivery charges. Always use the tier that matches your actual usage — the all-in rate at 1,000 kWh is the standard comparison point for most Dallas households.

Current Dallas Electricity Rates: March 2026

Based on current PowerToChoose.org data and market monitoring as of March 12, 2026:

Estimates based on 937 kWh/month usage, Oncor delivery at $4.23/mo + 5.0¢/kWh.

The same class of 12-month fixed-rate plans was priced 2–4¢/kWh higher during summer 2025 peak demand (June–August). A customer who locked in at 11¢/kWh in summer 2025 is paying roughly $19/month more than a customer who locks in a comparable plan today at 9.2¢/kWh.

Locking in now for 12 months means your current spring rate covers all of summer 2026 — including the July–August peaks when variable rates can spike above 20¢/kWh.

Provider Overview: Who Serves Dallas

Chariot Energy and Gexa Energy consistently offer among the lowest fixed rates in Dallas. They operate on lean cost structures with competitive wholesale purchasing. Chariot is known for straightforward contracts; Gexa for offering renewable and non-renewable options at competitive prices. Customer service is adequate but not premium. Best for price-focused customers who rarely need support.

APG&E and Discount Power often undercut even Chariot/Gexa on energy-only rates. Read plan documents carefully — some plans have bill credits that only apply at specific kWh thresholds, making them cheaper at 1,000 kWh but more expensive at 700 or 1,400 kWh.

Green Mountain Energy is the dominant renewable energy REP in Texas. Their 100% renewable plans price roughly 0.5–1.5¢/kWh above comparable non-renewable plans. For customers who want proven renewable sourcing with decent customer support, Green Mountain is the reliable choice.

4Change Energy bundles 4% of your bill as a charitable donation to local causes with each plan. Rates are competitive — typically mid-market — and they offer standard 12-month fixed terms. A solid option for customers who want value-aligned energy without paying a premium.

TXU Energy and Reliant Energy are Texas's largest retail electricity providers. They price 2–4¢/kWh higher than budget competitors but offer stronger customer service, robust mobile apps, smart thermostat programs, and loyalty rewards. TXU's MyAccount and Reliant's app are among the best in the Texas market. Worth the premium for customers who want reliability, bill guarantees, and responsive support.

All-In Dallas Bill Estimates: March 2026

These estimates use a competitive fixed-rate plan at 9.5¢/kWh energy-only plus Oncor delivery charges:

Note: Bill credits embedded in some plans change the effective rate at each tier. Always verify rates on PowerToChoose.org at your actual kWh level.

Dallas electricity usage follows a sharp seasonal curve:

• March–April: 600–800 kWh/month (mild weather, lowest usage)
• June–August: 1,200–1,800 kWh/month (peak cooling demand)
• September–November: 800–1,000 kWh/month (shoulder season)
• December–February: 900–1,100 kWh/month (heating demand, mostly gas but some electric)

The Dallas metro's climate is hotter and drier than Houston, with less humidity-driven cooling load — explaining why Dallas's 937 kWh monthly average is lower than Houston's ~1,590 kWh. However, summer peaks in DFW can be severe: 105°F+ days drive central air conditioning near-continuously, easily doubling spring usage.

5 Steps to Find the Best Dallas Electricity Rate Today

Step 1: Pull your last 3 electric bills Find your average monthly kWh. Your actual usage — not the national average — determines which plan tier applies to you.

Step 2: Go to PowerToChoose.org Enter your zip code and monthly kWh estimate. Sort by "Price/kWh at 1,000 kWh" (or whichever tier matches your usage). Filter for fixed-rate, 12-month plans.

Step 3: Compare all-in rates at your usage tier Ignore plans that are cheap at 1,000 kWh but expensive at your actual level. Some plans use bill credits that only activate at a specific tier — read the Electricity Facts Label (EFL) for each plan you're considering.

Step 4: Check the contract terms Look for: early termination fee (typically $150–$250), auto-renew policy, deposit requirement (if any), and renewable content percentage.

Step 5: Switch online — it takes 10 minutes Switching providers in Texas is free. Your power stays on continuously. The new provider notifies Oncor, and your billing switches within 1–5 business days. There's no meter visit, no service interruption.

Does DFW Cover the Same Oncor Territory?

Yes. Oncor serves the entire core of the DFW metroplex — Dallas, Fort Worth, Arlington, Plano, Garland, Irving, Frisco, McKinney, Allen, Carrollton, Richardson, Grand Prairie, and hundreds of surrounding communities. When you shop on PowerToChoose.org with a DFW zip code, you'll see the same REPs and similar rates across the region.

Exceptions to watch for:

• Denton: Served by Denton Municipal Electric (DME), a city-owned utility. DME customers cannot choose a different REP.
• Garland: Partially served by Garland Power & Light (GP&L), a municipal utility. Check your bill or address carefully.
• CoServ territory (parts of Denton and Collin counties): CoServ is an electric cooperative. Co-op members cannot shop for alternative REPs.

If you're outside these municipal/co-op zones, you're almost certainly in Oncor territory and can shop freely.

Spring 2026: Why Now Is the Right Time

The spring switching window — roughly February through May — is when Dallas electricity rates hit their annual low. Here's why:

1. Demand is at its lowest. Mild spring temperatures mean minimal air conditioning and heating load across ERCOT. Lower demand = lower wholesale electricity prices = lower retail plan pricing.

2. REPs compete hard for spring customers. Retail providers know that customers locked in on spring fixed-rate plans stay with them through the profitable (for variable-rate customers: expensive) summer months. They offer their sharpest pricing to win spring sign-ups.

3. Locking in now hedges summer risk. ERCOT summer demand forecasts for 2026 show continued growth from data center load in North Texas. Any summer heat event or grid stress can push spot prices above $9/kWh. A fixed-rate plan insulates you entirely.

Common Mistakes Dallas Electricity Shoppers Make

Mistake 1: Comparing rates at different usage tiers Plan A at 8.9¢/kWh (1,000 kWh tier) might actually be more expensive than Plan B at 11¢/kWh (1,000 kWh tier) if you use 1,500 kWh — because Plan A may have a bill credit that disappears above 1,000 kWh. Always check the EFL at your usage level.

Mistake 2: Ignoring the early termination fee Most 12-month fixed plans charge $150–$250 to cancel early. If you're planning to move within the next 12 months, consider a shorter 6-month term or a plan with no ETF (typically month-to-month, which carries higher rates).

Mistake 3: Letting the contract auto-renew REPs are required to notify you before your contract expires, but renewal offers are rarely the most competitive rate available. Treat each renewal notice as a prompt to shop PowerToChoose.org again.

Mistake 4: Choosing by brand alone TXU and Reliant are reliable, but their advertised rates are typically 2–4¢/kWh above what budget competitors offer. If price is your primary concern, compare all providers — not just the ones with the most advertising.

Dallas Electricity and Texas Solar Buyback

Dallas residents with rooftop solar can participate in net metering programs through several REPs, where excess generation is credited against your usage. Under Texas's deregulated model, you choose a REP with favorable buyback terms rather than being locked into your TDU's rate.

In 2026, several Dallas-area REPs offer competitive solar buyback rates for Oncor territory. For a full comparison, see our Texas solar buyback programs guide.
