Arlington TX Electricity Plans: Real Cost at 500 and 2,000 kWh

If you are shopping for electricity in Arlington, Texas, the number that matters is rarely the teaser rate on a mailer. It is the all-in average price at the usage level that matches your home or small business — especially at 500 kilowatt-hours (kWh) and 2,000 kWh. Those two bookends are not marketing gimmicks. Texas rules require every residential retail plan’s ¹ to show the total average price, in cents per kWh, at 500, 1,000, and 2,000 kWh per month. Read those columns, and you can see whether a plan that looks cheap for a light month still works when the air conditioner runs hard.

This guide walks through how choice works in competitive Texas markets, how to read those tier prices, what statewide average rates imply in dollars at 500 and 2,000 kWh, and how plan design (credits, base fees, variable rates) can flip the ranking once your meter moves.

Why 500 and 2,000 kWh define the real price

A kilowatt-hour is the standard unit on an electric bill: roughly the energy of a 1,000-watt appliance running for one hour. Your monthly bill multiplies usage by price — but “price” in Texas retail plans is often not a flat cents-per-kWh figure. Many offers fold in a monthly base charge, pass through regulated delivery charges from the wires company, and layer on bill credits that only apply if you use enough energy.

That is why the Public Utility Commission of Texas (PUCT) forces a standardized disclosure. Under ¹, the Electricity Facts Label (EFL) must express the total average price for electric service in cents per kWh, rounded to the nearest tenth of a cent, at 500, 1,000, and 2,000 kWh for residential customers. The average is meant to reflect recurring charges (excluding certain taxes), so shoppers can compare unlike products on the same page.

Think of 500 kWh as a light month — a smaller apartment, mild weather, careful use — and 2,000 kWh as a heavy month for many single-family homes with strong cooling load. A plan that quotes a rock-bottom average at 1,000 kWh because of a conditional bill credit can look punitive at 500 kWh (if you miss the credit threshold) or at 2,000 kWh (if the credit stops helping once usage climbs). The 500 and 2,000 columns exist to catch that mismatch before you enroll.

Power to Choose’s own ² flags a related trap: many plans charge a minimum usage fee if you use less than a set amount — often framed around cutoffs such as 500 or 1,000 kWh. That fee may or may not be obvious on the monthly bill, which is another reason the EFL, not the headline, is the document to trust.

How electricity shopping works in Arlington

Texas opened most of the ERCOT market to retail competition after the Legislature passed restructuring legislation often known as Senate Bill 7, which defined ³ as the freedom of a retail customer to purchase electric services from the provider of their choice. In plain English: in competitive areas, you choose who sells you the energy (the retail electric provider, or REP). You do not choose who owns the poles and wires.

⁴, the PUCT’s official comparison site, describes itself as the unbiased electric choice website where certified providers can list offers. Enter your ZIP code to see plans for your address. The site’s ² is blunt about geography: not every Texan has choice. Municipal utilities and cooperatives were not required to open to competition, so some communities still have a single bundled utility. Arlington households in competitive territory shop like other North Texas customers: pick a REP, keep the same wires company for delivery and outages.

That wires company is a transmission and distribution utility (TDU). ⁵, which calls itself the largest energy delivery company in Texas, explains the split clearly: in most of Texas you choose a REP that sets rates and plans; Oncor does not sell power, set your plan, or send the retail bill. Your address determines the TDU that delivers. Oncor’s ⁶ pages point new service customers to PowertoChoose.org. Power to Choose’s published ⁷ includes Oncor alongside other delivery utilities such as CenterPoint Energy and Texas-New Mexico Power. When you shop with an Arlington ZIP, confirm which TDU the results screen assigns — delivery charges are regulated and pass through regardless of which REP you pick.

Reliability and outages stay with the wires company. The ² states that switching REPs does not change who maintains poles and wires or who restores service. For grid operations across most of Texas, ⁸ is the independent system operator that keeps the bulk power system in balance. When you switch REPs, ERCOT sends the confirmation mailer described in the shopping guides.

The PUCT’s ⁹ is the place for complaints, disconnection help, and “I need help choosing a retail electricity plan.” Use it when a bill dispute stalls with the REP.

Reading the Electricity Facts Label without getting spun

Power to Choose’s ¹⁰ defines the Electricity Facts Label as the fact sheet with standardized information on contract terms, pricing, fees, and renewable content — required so customers can make an apples-to-apples comparison. The ² repeats the rule: companies must provide an EFL for each plan with standardized rates, fees, and contract terms.

What to pull from the label before you care about brand names:

• Average price at 500 / 1,000 / 2,000 kWh. This is the legal comparison grid for residential plans under ¹. If 500 is much higher than 1,000, you are looking at a product that depends on hitting a usage sweet spot (often a bill credit). If 2,000 jumps, the plan may punish high summer use.
• Product type. Fixed, variable, or indexed — defined in both the rule and the ¹¹ guide.
• Base charge. The glossary defines a ¹⁰ as a flat monthly fee regardless of kWh used. On a 500 kWh month, a large base fee spreads across fewer kilowatt-hours and inflates the average cents-per-kWh.
• Contract length and early termination. Plans of three months or more may carry a cancellation penalty; month-to-month products are treated differently under the rules and shopping guides.
• Renewable content. Useful if carbon intensity matters to you; it is disclosed on the EFL even when it does not change the delivery path to your meter.

Power to Choose’s ¹² page starts with the right habit: ask your current provider for the total electric rate per kWh based on 1,000 kWh average usage (excluding taxes and non-recurring fees), then ask whether a new offer’s rate includes energy, transmission and distribution charges, and recurring fees. That is how you avoid comparing a partial energy-only teaser to a complete EFL average.

What 500 vs 2,000 kWh actually costs using state benchmarks

Plan offers move every day, so this article will not pretend a single Arlington “best rate” is frozen in time. What you can anchor on is what Texans actually paid on average, then translate that into dollars at the two usage levels.

The U.S. Energy Information Administration’s ¹³ reports average prices of electricity to ultimate customers by state and sector. For Texas residential customers, that table shows 16.99 cents per kWh for April 2026 and 15.52 cents per kWh for April 2025. Those are statewide averages across competitive and non-competitive areas, not a quote for one Arlington plan — but they are a reality check for any EFL that looks “too good” without reading the fine print.

Apply that April 2026 residential average as a back-of-the-envelope bill:

Move to the U.S. context and Texas still looks competitive on some measures and ordinary on others. EIA’s explainer on ¹⁴ puts the 2025 U.S. annual average retail price at about 13.63¢/kWh across all customer classes, with the residential average at 17.30¢/kWh. Texas’s April 2026 residential average of 16.99¢ sits near that national residential ballpark — which means shopping still matters, but the bigger miss for many households is locking a plan whose EFL only looks cheap at a usage level they never hit.

EIA’s ¹⁵ also shows why wholesale and all-sector averages can look much lower than your residential bill: the state’s average retail price across all sectors was 9.79¢/kWh (rank 42), reflecting industrial and other loads that buy power differently than a house on a residential REP product. Do not compare your home EFL to an all-sector state average and call it a bargain.

Two practical uses of the 500 / 2,000 math:

1. Print your last 12 months of kWh (or pull them from your smart meter portal). Circle the low month and the high month. Compare EFLs at the tier closest to each — not only at 1,000.
2. Convert EFL cents to dollars the same way: cents ÷ 100 × kWh. A plan at 22.0¢ at 500 kWh is about $110 before taxes; a plan at 14.0¢ at 2,000 kWh is about $280. If your summer months sit near 2,000, the second number runs your budget, not the winter teaser.

Delivery charges from the TDU are inside the EFL’s average price construction for the products you see on Power to Choose, but they still matter conceptually: every REP in the same TDU territory faces the same regulated delivery tariff. Shopping among REPs changes the energy product and fees the REP controls; it does not swap Oncor for a different set of poles.

Plan types, credits, and the traps that flip the ranking

Power to Choose’s ¹¹ page sorts the menu most Arlington shoppers actually see.

Fixed-rate plans lock the energy price for the contract term, with narrow exceptions for TDU fee changes, ERCOT or Texas Regional Entity administrative fees, or new government-imposed fees beyond the REP’s control — language that appears in both the shopping guide and the ¹⁰ definition of a fixed-rate plan. Fixed products help budgeting. They also mean you wait out the term if market prices fall.

Variable (changing) rate plans have no monthly contract or cancellation fee in the guide’s description, but the price per kWh can move month to month with the market and the company’s discretion. That flexibility cuts both ways when heat waves or winter storms tighten the system.

Indexed (market) rate plans also move monthly, but according to a disclosed formula tied to a public index rather than pure company discretion. The guide urges customers to ask how the formula works and how change notices arrive.

Prepaid plans are pay-as-you-go: often no deposit and sometimes no long contract, but you must keep a balance funded. The guide notes prepaid products generally charge a higher rate than non-prepaid plans, and service can disconnect with little notice if the balance runs low.

Contract length deserves its own look. Some offers are month-to-month; others run a year or longer. The Plan Options guide warns that contracts of three months or more may include an early cancellation penalty, and that many plans default to a higher month-to-month price if you let a term expire without a new contract. That rollover surprise is a common reason a bill spikes even when usage did not.

Then come the structures that make 500 and 2,000 diverge:

• Minimum usage fees. As the ² explains, if you use less than the plan’s minimum, you can be charged a fee that effectively raises your average price on light months — exactly the 500 kWh problem.
• Bill credits tied to a usage band. A credit that unlocks near 1,000 kWh can make the middle column look spectacular while 500 and 2,000 look ordinary or worse. The EFL’s three columns are how you detect that.
• Base charges. A high fixed monthly fee hurts most at low usage because it is spread over fewer kWh in the average-price formula.

None of these designs is automatically “bad.” A predictable high user might happily take a credit-centered plan. A snowbird apartment that sits near 500 kWh in shoulder seasons should treat a steep 500 column as a hard no.

Is your Arlington usage closer to 500 or 2,000?

National averages are not Arlington ordinances, but they set expectations for a hot southern metro. EIA’s explainer on ¹⁶ reports that the average U.S. household consumes about 10,500 kWh of electricity per year — roughly 875 kWh per month if usage were perfectly flat. It also notes that single-family detached homes in the South consume the most electricity on average, in part because southern homes are more likely to rely on electric heating and use more air conditioning.

End-use shares from that same EIA page show why Texas summers stretch bills: in 2020, air conditioning accounted for about 19% of residential site electricity consumption nationally, with space heating and water heating each about 12%. Lighting and refrigerators follow. About 89% of U.S. homes used air conditioning in 2020, up from 57% in 1980. In North Texas, cooling is not optional for much of the year, so many households will see months closer to 1,500–2,000+ kWh even if their annual average looks nearer 1,000.

¹⁷ guidance notes that as much as half of household energy use can go to heating and cooling, and it points to sealing, insulation, and efficient equipment as high-impact moves. That matters for plan shopping because a 400 kWh swing between a leaky attic June and a sealed attic June can change which EFL column predicts your bill.

For Arlington specifically, skip national folklore and read your meter. Pull 12 months of usage from your REP or from Smart Meter Texas if you have access. Mark:

• the minimum month (is it near 500?),
• the median month,
• the maximum month (is it nearer 2,000?).

Shop the plan as if those three months will each show up on a real bill — because they will.

A decision checklist before you switch or renew

1. Confirm choice with your ZIP on ⁴. If no competitive plans appear, you may be outside retail choice.
2. Open every EFL and write down the average price at 500 and 2,000 kWh, not only 1,000.
3. Match the product type to your risk tolerance using the ¹¹ definitions — fixed for budgeting, variable/indexed only if you can watch prices, prepaid only if you can monitor balances.
4. Ask the ¹² list: all-in rate at 1,000 kWh, what is included, how variable prices change, deposit, payment options, what happens at expiration, missed-payment rules, and early termination penalties.
5. Check minimum usage language on the EFL and terms so a low month does not trigger fees described in the ².
6. Understand the switch timeline. After you enroll, ERCOT mails a confirmation; you generally have three business days to cancel after receiving terms, and the switch typically completes within seven business days with no lapse in service, per the FAQ. There is no switching fee unless you request a special meter reading outside the normal cycle — but breaking an existing fixed contract can still cost an early termination fee.
7. Know your complaint path. Billing fights start with the REP; unresolved issues go to the PUCT customer hotline noted on Power to Choose (1-888-PUC-TIPS). Outages go to the TDU — for Oncor territory, the residential site lists outage reporting at 888.313.4747.

If you are renewing rather than moving, treat the renewal offer like a new plan: demand the EFL, compare it at your actual high and low months, and calendar the contract end date so you are not rolled onto a default month-to-month rate the Plan Options guide warns may be much higher.

Small commercial notes and cutting kWh after you pick a plan

Small businesses in competitive Texas areas also shop REPs, but their disclosure tiers differ. The same ¹ rule requires small commercial EFLs to show average prices at 1,500, 2,500, and 3,500 kWh per month (with a 30% load-factor assumption when demand charges apply). A café or shop should not use the residential 500 / 2,000 grid as its only lens. Power to Choose maintains separate ¹⁸ resources for non-residential shopping.

After the rate is set, kilowatt-hours still dominate the bill. EIA’s home electricity explainer and ENERGY STAR’s ¹⁷ resources converge on the same idea: cooling and heating drive consumption in climates like North Texas, and sealing, insulation, and efficient HVAC and appliances cut usage at every price. Oncor’s residential pages also point customers toward energy efficiency programs on the wires-company side — separate from REP shopping, but relevant to the long-term bill.

Bottom line for Arlington shoppers

Arlington customers in competitive ZIP codes buy a REP product and receive delivery from whichever TDU Power to Choose assigns to their address — often Oncor in North Texas — while shopping on ⁴ with an EFL in hand. Texas law makes 500 and 2,000 kWh mandatory disclosure points so you can see the real average price when usage is light or heavy. Statewide residential averages near 17¢/kWh imply roughly $85 at 500 kWh and $340 at 2,000 kWh as a recent EIA-based yardstick — but your signed EFL is the contract that matters. Pick the plan whose 500 and 2,000 columns both survive your actual meter history, not the one that only wins at a usage level you never hit.
