Dallas TX Electricity Plans: Real Cost at 500 and 2000 kWh
If you live in Dallas and shop for electricity online, you have probably seen three prices on every plan: an average rate at 500 kWh, another at 1,000 kWh, and a third at 2,000 kWh. Those numbers are not random marketing tiers. They are a legal disclosure format designed to show how the same plan can feel cheap at one usage level and expensive at another.
That matters in North Texas more than most places. A studio apartment in Uptown and a four-bedroom home in Plano can both be in the same competitive market, but one might land near 500 kWh in April and the other above 2,000 kWh in August. Pick a plan optimized for the wrong band and you can overpay for an entire contract.
This guide explains what those 500 and 2,000 kWh figures actually mean, how Dallas bills are built, and how to translate an Electricity Facts Label (EFL) into dollars you can compare before you enroll.
Dallas sits in Texas's competitive market — but wires and supply are separate
Since 2002, most Texans — including Dallas-area residents — have been able to choose a retail electric provider (REP) while their local utility continues to deliver power over the poles and wires ¹. REPs sell you the energy commodity; they do not own the grid ².
When you shop by ZIP code on Power to Choose, the site may ask you to confirm your transmission and distribution utility (TDU) if more than one serves your area Power to Choose. Oncor Electric Delivery is among the TDUs listed on the commission's TDU contact sheet ³, and Oncor's residential pages direct new customers to enroll through competitive providers on Power to Choose ⁴. For most Dallas-area addresses, Oncor is the delivering utility — but always confirm through the site rather than assuming.
Your REP bill combines two big pieces:
- Energy charges from the REP you select (this is what you shop for).
- Transmission and distribution (TDU) charges from your local wires company, passed through on your bill at regulated rates that apply to every customer in that territory ⁵.
Because TDU fees are the same for all REPs in your area, they are not the differentiator when you compare plans. The spread in advertised prices comes from REP energy rates, monthly base fees, bill credits, minimum-use rules, and contract structure ².
Power to Choose is the official, unbiased electric choice website of the Public Utility Commission of Texas (PUCT), where certified providers can list offers for free Power to Choose.
Why 500 kWh and 2,000 kWh appear on every plan
Texas law requires each residential EFL to show the total average price for electric service at three monthly usage levels: 500, 1,000, and 2,000 kilowatt-hours ⁶. That average is expressed in cents per kWh, rounded to the nearest tenth of a cent, and must reflect all recurring charges except sales taxes and certain pass-through taxes ⁶.
The EFL exists so customers can make an "apples-to-apples" comparison across offers ². It is standardized by the PUCT and must accompany every plan ².
Important nuance: the three EFL averages are calculated benchmarks, not promises about your exact bill. Usage is measured in kilowatt-hours during each billing period and listed on your bill as "kWh used" ². If you consume 847 kWh, none of the three printed averages is precisely your rate — but the nearest benchmark (usually 1,000 kWh) is a starting point, and the full EFL breakdown lets you model your actual usage.
What goes into the average ¢/kWh
For fixed-rate plans, the EFL average bundles:
- The REP's energy charge per kWh
- Your TDU's per-kWh delivery charge (passed through)
- Monthly base or customer charges, spread across the usage level
- The effect of bill credits or minimum-use penalties at that usage level ⁶
Fixed charges hurt low users most. A $9.95 monthly base fee adds about 2.0¢/kWh at 500 kWh but only 0.5¢/kWh at 2,000 kWh. That math alone explains why the 500 kWh column is often the highest ¢/kWh on an EFL even when the underlying energy rate is flat.
Who lands at 500 kWh vs 2,000 kWh in Dallas?
Neither figure is "correct" for every household. They are reference points the regulator chose to expose plan behavior at low, middle, and high consumption ⁶.
Roughly 500 kWh/month often describes:
- Small apartments with minimal daytime occupancy
- Mild shoulder months (March, April, October) even in larger homes
- Units where heating and cooling loads are modest
Roughly 2,000 kWh/month often describes:
- Larger single-family homes running central air heavily through Dallas summers
- Months when air conditioning dominates load
- Homes with pools, aging HVAC systems, or multiple refrigerators
The U.S. Energy Information Administration reports Texas's statewide average retail electricity price at 9.79 cents/kWh across all customer classes and usage patterns ⁷. That statewide figure is a useful backdrop, but your Dallas plan's EFL averages will differ because they isolate residential recurring charges at specific usage tiers, not a blended annual statistic.
The Department of Energy notes that in an average-sized home, air conditioning alone can consume more than 2,000 kWh per year — before counting other appliances ⁸. In North Texas, much of that load concentrates in a few summer months, which is why a single month can approach or exceed 2,000 kWh even when your annual average sits near 1,100 kWh.
To estimate your own band, gather 12 months of kWh history from past bills or interval data from your smart meter portal. Power to Choose suggests asking your current REP for your all-in rate at 1,000 kWh before calling competitors — a baseline for comparison ⁹. Then check whether your summer peak approaches or exceeds 2,000 kWh and whether winter months dip toward 500 kWh. The wider that swing, the more dangerous it is to choose a plan based on a single benchmark alone.
Translating EFL averages into real dollars
The Department of Energy's standard bill formula is straightforward: multiply kilowatt-hours by your all-in rate, then add any charges not already embedded in that average ¹⁰:
Monthly energy cost (before tax) ≈ (EFL average ¢/kWh ÷ 100) × actual kWh used
Annual cost follows the same pattern: annual energy consumption × utility rate per kWh = annual cost to run ¹⁰.
Example A — low usage month (500 kWh)
The following rates are illustrative only — always read the live EFL for plans available to your address.
Suppose Plan X shows 16.4¢/kWh at 500 kWh on its EFL.
- Energy subtotal: 16.4¢ × 500 = 8,200¢ = $82.00
- Add applicable sales tax on top of the energy subtotal
- Estimated pre-tax bill ≈ $82.00
Now compare Plan Y at 13.1¢/kWh at 500 kWh:
- 13.1¢ × 500 = $65.50
At 500 kWh, a 3.3¢/kWh gap is about $16.50/month — nearly $200/year if every month looked like that.
Example B — high usage month (2,000 kWh)
Same illustrative plans at the 2,000 kWh tier:
- Plan X: 12.8¢/kWh → 12.8¢ × 2,000 = $256.00
- Plan Y: 13.6¢/kWh → 13.6¢ × 2,000 = $272.00
Notice the flip: Plan Y was cheaper at 500 kWh but more expensive at 2,000 kWh. That inversion is common when one plan carries a low base charge and a bill credit that disappears at higher usage, while another plan has a higher energy rate but no credit cliff.
Example C — annual blended cost
If your year averages 1,100 kWh/month but swings from 550 kWh in April to 2,100 kWh in August, do not multiply a single EFL column by twelve. Model at least three months at each tier, or pull the per-kWh energy charge and fixed fees from the EFL disclosure chart and calculate each month directly ⁶.
Plan mechanics that distort 500 vs 2,000 kWh pricing
Fixed vs variable vs indexed
A fixed-rate plan locks your energy price for the contract term except for allowed pass-through changes in TDU fees, ERCOT administrative fees, or new laws ⁵. That predictability helps budgeting.
Variable and indexed plans can change monthly. Indexed rates tie to a public formula ⁵. The EFL still shows 500/1,000/2,000 averages for the first cycle, but future bills may diverge ⁶.
Minimum usage fees and low-use penalties
Many plans charge extra if usage falls below a threshold — commonly under 500 or 1,000 kWh per billing period ¹¹. The fee may not appear as a separate line item on your bill, which makes the EFL essential ¹¹. Power to Choose's filters can flag plans with minimum-use requirements ².
At 500 kWh, you are right at the cliff on many plans. A plan with a minimum 1,000 kWh requirement can punish apartment dwellers even when the 1,000 kWh advertised rate looks attractive.
Bill credits and tiered energy rates
Some plans offer credits when usage lands in a band (often 1,000–1,999 kWh). At 500 kWh you miss the credit; at 2,000 kWh you may exceed the band and lose it again. The EFL's three-column spread reveals that pattern without reading marketing copy.
Always read the disclosure chart for tiered energy charges — rates that jump after a stated kWh threshold — not just the headline average ⁹.
Base charges
REPs may apply a flat monthly fee regardless of usage ². When comparing two plans:
- Confirm the rate includes transmission, distribution, and recurring fees ⁹.
- Compare the EFL line at your typical usage, not the site default.
- If your usage is volatile, compare both 500 and 2,000 kWh columns.
How air conditioning pushes Dallas bills toward 2,000 kWh
Cooling dominates North Texas summer bills. The Department of Energy recommends buying an efficient unit and reducing runtime because central air conditioning is a major electricity draw; in an average-sized home it can exceed 2,000 kWh annually on its own ⁸.
You can estimate any appliance's daily contribution with DOE's formula ¹⁰:
(Wattage × hours used per day) ÷ 1,000 = daily kWh
Applied to a hypothetical 3,500-watt central AC running 12 hours: (3,500 × 12) ÷ 1,000 ≈ 42 kWh in that day alone. Ten days at that level add 420 kWh on top of baseline loads — enough to push a 1,200 kWh household into the 2,000 kWh pricing tier where bill credits and tier breaks matter.
That seasonal spike is why a plan that looks optimal at 1,000 kWh on Power to Choose may be wrong for July and August. Model summer at 2,000 kWh even if your annual average is lower.
Shopping step-by-step for your usage band
1. Start on Power to Choose with honest usage assumptions
Enter your Dallas ZIP on Power to Choose. Confirm your TDU when prompted. Use filters for contract length, renewable content, and — critically — minimum usage fees ².
When sorting results, change the estimated usage toggle to 500 kWh if you are in a small unit or comparing shoulder months, and to 2,000 kWh if you are sizing for summer in a larger home. The site displays plan averages aligned with those benchmarks Power to Choose.
2. Open the EFL for every finalist
Before enrolling, open the EFL link. Verify:
- Average ¢/kWh at 500, 1,000, and 2,000 kWh ⁶
- Early termination fee and contract term ⁵
- Whether the price is fixed, variable, or indexed ⁹
- Minimum usage fees or bill credits ¹¹
Electric companies are required to provide an EFL for each plan; use it rather than headline ads alone ¹¹.
3. Ask the ten comparison questions
Power to Choose publishes a standard question list, including: "What will I pay per kWh based on 1,000 kWh average monthly usage?" and "Does this rate include everything — energy, transmission, distribution, and recurring fees?" ⁹. Adapt those questions to 500 or 2,000 kWh when that better matches your reality.
4. Switch without a service interruption
Choosing a new REP does not interrupt delivery; reliability is unchanged ¹. A switch typically completes within seven business days ¹. You have a three-business-day right to cancel after receiving contract documents if your terms include a penalty ¹.
Small business owners in Dallas: same EFL logic, different benchmarks
Most commercial EFLs use 1,500, 2,500, and 3,500 kWh instead of the residential trio ⁶. If you operate a small storefront, salon, or office in Dallas with lighter HVAC load, your monthly use may sit closer to the commercial 1,500 kWh column than to 2,000 kWh — but summer cooling can still spike you upward.
Apply the same rule: locate your actual usage band on the EFL, model fixed charges at low months, and do not rely on a single advertised average.
Red flags when the 500 kWh and 2,000 kWh columns disagree sharply
Watch for:
- Large spreads (3¢+) between low and mid usage: likely bill credits or minimum-use traps.
- Higher ¢/kWh at 2,000 than at 1,000: possible credit cap or tiered rate jump at high usage.
- Much lower ¢/kWh at 1,000 than both 500 and 2,000: classic credit band centered on 1,000 kWh.
Power to Choose allows filtering for minimum-use fees; use it if you routinely land near 500 kWh ¹¹.
Regulated vs competitive: why this only applies to most Dallas addresses
Texas deregulated the sale of electricity in much of the state, but not every meter is eligible to shop. If your ZIP on Power to Choose returns no offers, you may be in an area still served by a single integrated utility Power to Choose. For eligible addresses, the competitive market has run since 2002 ¹.
Apartment renters and new movers should start service at least a week before move-in. If no provider is in place, you may be assigned a provider of last resort at unfavorable rates until you shop ⁵.
Putting it together: a Dallas shopper checklist
- Know your kWh band. Pull twelve months of usage; note the highest and lowest month.
- Compare EFL columns at both 500 and 2,000 kWh if your range spans them.
- Calculate dollars, not just cents: multiply each candidate's EFL average by your expected kWh.
- Separate REP energy from TDU delivery mentally — delivery is pass-through and identical across REPs in your territory ⁵.
- Avoid minimum-use traps if you are often below 1,000 kWh ¹¹.
- Re-shop before contract expiry; month-to-month defaults can price much higher ⁵.
- Use official sources — Power to Choose and the EFL — rather than headline rates in ads ².
The 500 and 2,000 kWh figures are not decorative. They are the PUCT's way of forcing plans to show their true cost at low and high consumption before you commit ⁶. In Dallas's competitive market, the shoppers who win are not always the ones who find the lowest number at 1,000 kWh — they are the ones who match the plan's math to the kWh they actually use, in both mild springs and brutal Augusts.
