Irving TX Electricity Plans: What You Really Pay at 500 and 2,000 kWh

If you live in Irving and you are shopping for power, the number that matters is not the teaser rate on an ad. It is what you will actually owe after delivery charges, monthly fees, and whatever quirks sit inside the plan. Texas publishes those all-in figures at three usage levels—500, 1,000, and 2,000 kilowatt-hours (kWh)—precisely so you can stress-test offers against a small apartment month and a heavy air-conditioning month. This guide walks through how that math works in Irving, why 500 kWh and 2,000 kWh can tell completely different stories about the same contract, and how to shop without getting blindsided.

Why the headline rate is a trap in North Texas

A kilowatt-hour is energy use over time: one kilowatt of demand running for one hour. Your meter totals those hours into a monthly kWh count, and your Retail Electric Provider (REP) turns that count into a bill. Marketing copy often highlights a single cents-per-kWh figure that looks great at one usage level and worse at another. That is not a glitch. Flat monthly charges, minimum-usage fees, bill credits, and tiered energy prices all change the average price when you divide total dollars by total kWh.

Texas regulators designed the ¹ as the apples-to-apples fix: a nutrition-label style disclosure so you can compare plans in a standardized format. The Public Utility Commission of Texas (PUCT) requires the EFL’s average price for residential service to be shown at 500, 1,000, and 2,000 kWh, rounded to the nearest tenth of a cent, and to reflect recurring charges including transmission and distribution (TDU) pass-throughs while excluding certain taxes. That framework is why Irving shoppers should treat three columns as the real product—not the single number in a banner ad.

Statewide context helps set expectations. According to the U.S. Energy Information Administration’s ², Texas residential customers paid an average of 16.99 cents per kWh in April 2026, versus 15.52 cents a year earlier. The U.S. residential average in the same month was 18.83 cents per kWh. Those EIA averages are revenue-per-kWh proxies that blend energy, delivery, and other billed amounts. They are not a quote for your Irving plan, but they are a useful yardstick when an “amazing” offer lands far above or below the pack.

How choice works in Irving: REP, wires, and ERCOT

Irving sits inside the competitive retail market that covers most of the Electric Reliability Council of Texas (ERCOT) footprint. If you are in that competitive area and not served by a municipal utility or cooperative that opted out of retail choice, you pick the company that sells you energy—the REP—while a separate wires company delivers it. The PUCT’s consumer guidance puts it plainly: residents in the ERCOT region who are not on a co-op or muni can ³, and ⁴ is the Commission’s official comparison site.

Oncor Electric Delivery is the transmission and distribution utility for Irving. Oncor’s own ⁵ lists Irving among the cities in its certified service territory. Oncor does not sell you the electricity itself. As Oncor explains in its customer explainer, customers buy power from a REP, receive the bill from that REP, and see Oncor’s costs as delivery, wires, or transmission-and-distribution charges passed through on that same bill (⁶).

ERCOT’s retail overview describes the same split: competitive retailers sell energy to end-use customers where retail competition is open, while the transmission and distribution service provider (TDSP) manages poles, wires, and meter reads. Oncor appears on ERCOT’s TDSP list in its ⁷. For Irving residents, that institutional split means outages and wire problems generally go to Oncor, while price, plan terms, and billing questions go to the REP.

Reading the Electricity Facts Label like a bill, not a brochure

The EFL is where 500 and 2,000 kWh stop being abstract. Under PUCT Substantive Rule 25.475, each product needs its own EFL, and the total average price for electric service must be expressed in cents per kWh at those three residential usage levels, reflecting recurring charges including applicable TDU charges for the disclosure method described in the rule (⁸). Fixed-rate products disclose the average price across the term’s pricing structure; variable products disclose the first-billing-cycle average and warn that later months can change.

Power to Choose is built around that disclosure culture. The site is the ⁴ of the PUCT, open to providers to list offers for free so customers can compare. When you enter an Irving ZIP code, you are not just browsing slogans—you are looking at offers that should map back to EFL math for your delivery area.

Practical habit: open the EFL (often labeled as a facts sheet) for every finalist plan and write down the three average prices side by side. If your summer months look like 2,000 kWh and your mild months look like 800–1,200 kWh, the 2,000 column and the 1,000 column both matter. If you are in a small apartment that often lands near 500 kWh, that low-usage column is the one that can expose painful base charges.

WattKarma’s shopping guidance makes the same point for Texas homes: most households land somewhere between 1,000 and 2,000 kWh per month depending on size and habits, and the EFL’s three-tier average price is the reliable comparison tool because it folds in recurring charges rather than a naked energy rate (⁹). The same logic applies in Irving even when a blog example is written for another metro—delivery companies differ, but EFL rules do not.

What Oncor delivery alone costs at 500 and 2,000 kWh

Before you even pick a REP rate, Irving customers pay Oncor for delivery. Those charges are Commission-authorized and billed to the REP, which passes them through. Oncor’s ¹⁰ page breaks residential delivery into fixed monthly pieces (such as customer and metering charges) and variable per-kWh pieces (distribution system charge, transmission cost recovery, energy-efficiency cost recovery, and related factors). High summer usage raises the variable portion simply because more kWh move across the wires.

The PUCT publishes a monthly summary of residential TDU delivery charges. As of July 1, 2026, Oncor’s residential summary on the Commission’s ¹¹ page shows a $1.48 customer charge, a $2.58 metering charge, and volumetric charges of 6.1196 cents per kWh. The same table lists average Oncor residential delivery bills of $34.66 at 500 kWh, $65.26 at 1,000 kWh, and $126.45 at 2,000 kWh.

That table is delivery only—it is not your full light bill. But it already explains a big chunk of what “real cost” means in Irving:

• At 500 kWh, Oncor delivery alone is $34.66, or about 6.9 cents per kWh when you average the fixed pieces across low usage.
• At 2,000 kWh, delivery is $126.45, or about 6.3 cents per kWh on the same averaging basis.

Fixed charges bite harder when you use less. That is why two plans with identical energy rates can diverge sharply at 500 kWh once base fees stack on top of delivery.

Oncor’s customer explainer has used a simplified illustration of roughly a $4.23 fixed monthly amount plus about 5 cents per kWh for delivery in an earlier communication (⁶). Use the PUCT’s current monthly TDU table for shopping math, and treat older explainers as conceptual: delivery is a meaningful, usage-sensitive slice of the bill, not a rounding error.

Real cost at 500 kWh: when small homes get expensive plans

Five hundred kWh is a low-to-moderate residential month in North Texas—more common in mild shoulder seasons, compact apartments, or months when the house is empty for long stretches. It is also the usage level where plan design can punish you.

Start with a statewide all-in benchmark. Using EIA’s April 2026 Texas residential average of ², a 500 kWh month would land near $85 before you adjust for your specific plan’s quirks (500 × $0.1699 ≈ $84.95). If Oncor delivery is about $35 of that stack, the REP’s energy price, base charge, and any credits or fees make up the rest.

Now consider how EFL columns diverge. Suppose Plan A shows 18.0¢ at 500 kWh and 12.5¢ at 2,000 kWh on its EFL, while Plan B shows a flatter 14.5¢ at both levels. Those are illustrative structures, not live quotes—always pull current numbers from Power to Choose and the EFL—but the arithmetic is the point:

• Plan A at 500 kWh: 500 × $0.180 = $90 estimated average bill.
• Plan B at 500 kWh: 500 × $0.145 = $72.50 estimated average bill.

Plan A’s “cheap at high usage” marketing is irrelevant if you almost never hit the credit band or the high-usage tier. WattKarma’s usage-tier walkthrough for Houston makes the low-usage failure mode explicit: base charges and minimum-usage fees move the effective cents-per-kWh a lot at 500 kWh, and some plans add costs when usage falls below common cutoffs such as 500 or 1,000 kWh (Compare Houston Electricity Rates: Real Cost at 500, 1000, 2000 kWh). Irving shoppers see the same product structures; only the TDU line items differ.

Decision rule for ~500 kWh households: sort Power to Choose results by the 500 kWh average price, not the 1,000 kWh teaser. Prefer plans with low or zero base charges and no minimum-usage fee that you would trip. If a plan’s 500 kWh price is several cents higher than its 1,000 kWh price, that gap is often fixed fees or a usage cliff talking.

Real cost at 2,000 kWh: summer Irving and the high-usage column

Two thousand kWh is a heavy residential month—typical of larger homes, electric heat pumps in extreme weather, or long stretches of air-conditioning. The U.S. Department of Energy’s Energy Saver guide notes that heating and air conditioning together are typically about ¹², which is why North Texas summers can shove a household from a 1,000 kWh pattern into the 2,000 kWh disclosure column quickly.

Using the same EIA Texas average of 16.99 cents per kWh, 2,000 kWh implies roughly $340 for the month (2,000 × $0.1699 ≈ $339.80). Oncor delivery at that level is $126.45 per the July 2026 PUCT TDU summary—still large in dollars, but a smaller share of the all-in average than at 500 kWh because the fixed metering and customer charges are spread over more kilowatt-hours.

Return to the illustrative EFLs:

• Plan A at 2,000 kWh: 2,000 × $0.125 = $250.
• Plan B at 2,000 kWh: 2,000 × $0.145 = $290.

The ranking flipped. The plan that looked worse at 500 kWh becomes the better high-usage deal if—and only if—you actually consume near 2,000 kWh in the months that dominate your annual spend. That is why “real cost” for Irving is a calendar question, not a single-month screenshot. Pull twelve months of kWh from prior bills if you can. Count how many months sit near 500, near 1,000, and above 1,500. Weight the EFL columns the way your year actually behaves.

Bill-credit and usage-credit products intensify this. WattKarma describes usage-credit plans as products that apply a bill credit when monthly usage falls inside a provider-defined range—often marketed around credits such as $50 to $150—while usage outside the range simply means you miss the credit for that period (¹³). A plan can look spectacular at 2,000 kWh on the EFL because the modeled credit is baked into that average, then look ordinary or poor at 500 kWh when the credit never triggers. Model the credit at your kWh, not the brochure’s favorite tier.

Plan types that change the 500 vs. 2,000 story

The PUCT summarizes the main competitive products clearly. ¹⁴ keep the REP’s price per kWh from changing during the contract term except for certain pass-throughs such as TDU fee changes, ERCOT or Texas Regional Entity administrative fees, or new government-imposed costs. That stability helps budgeting, especially if you want a predictable summer. Variable month-to-month plans typically have no long contract or cancellation fee, but the rate can move at the REP’s discretion. Indexed plans tie the rate to a public index formula. Prepaid service is paid in advance on a pay-as-you-go basis and can sit on top of fixed, variable, or indexed pricing. Time-of-use products change the per-kWh charge by time of day or day of week; the EFL’s average price for those plans depends on the REP’s assumed mix of discounted versus premium hours, so your bill rises if you cannot shift load.

For Irving decision-making:

• Choose fixed if you value bill predictability through a long cooling season and you can live with the early-termination fee risk if you move.
• Choose variable only if you will watch the rate and are ready to switch quickly when it drifts.
• Treat time-of-use as a lifestyle product: nights-and-weekends discounts help only if laundry, dishwashing, and EV charging actually move off-peak.
• Treat usage credits as a targeting product: great when your monthly kWh is stable inside the band, risky when spring and summer swing wildly.

None of those product types erase Oncor delivery. They only change how the REP layer sits on top of wires charges that Irving customers pay either way.

Small businesses and shoppers outside Texas choice markets

Small-business owners in Irving often face the same EFL logic with different rate classes and demand charges once load grows. The residential 500 / 2,000 kWh columns still help a home-based business estimate the residential meter, but a storefront on a commercial tariff needs a broker or REP quote that reflects demand (kW) as well as energy (kWh). Do not assume a residential Power to Choose offer applies to a commercial premise.

If you are reading this from a regulated market—or from a Texas city served by a municipal utility or cooperative—the shopping steps change. You may have a single bundled utility rate instead of a REP-plus-TDU split. Choice states such as Ohio and Maryland run their own shopping portals and disclosure rules; the transferable skill is still to demand an all-in price at your usage level rather than a promotional energy-only number. EIA’s state average table remains a useful cross-check wherever you live: compare a quoted all-in residential price to the latest state residential figure in ² and ask why a deal sits far outside the local average.

A practical Irving shopping checklist

1. Confirm you are in competitive retail choice and note that Oncor is your TDU if you are in the Irving delivery territory listed in Oncor’s tariff. Use ⁴ with your exact ZIP code.
2. Export or write down twelve months of kWh. Mark your 500-ish months and your 2,000-ish months separately.
3. For each finalist, copy the EFL average prices at 500, 1,000, and 2,000 kWh. Convert each to dollars (price × kWh) so you are comparing bills, not abstractions.
4. Read the fine print for base charges, minimum-usage fees, bill credits, and early termination fees. The EFL and Terms of Service are the documents that matter; the PUCT’s facts-label page exists so you can demand that standardized disclosure (¹).
5. Separate delivery from energy in your head using the current Oncor line on the ¹¹. If two REP offers are within a fraction of a cent, delivery will not break the tie—but if one plan’s low-usage average is inflated, fixed fees usually will.
6. If you need help choosing a provider, the PUCT Consumer Protection Division contact path is listed on the Commission’s ³ page.

Irving’s market gives you real choice. The winning move is boring and effective: ignore the loudest rate, trust the three EFL columns, and price your actual 500 kWh months and 2,000 kWh months as if they were two different products—because for many plans, they are.
