CenterPoint and Oncor Delivery Charges: 2,000 kWh Texas Bill Math for May 2026

A large Texas home shopping electricity plans in May 2026 should not compare Reliant, TXU Energy, Direct Energy, Gexa, Rhythm, or other retail offers without separating the delivery-charge math first. CenterPoint in the Houston area and Oncor in North Texas deliver the power, and their pass-through charges can make two plans with similar energy rates feel very different once the bill reaches 1,500 to 2,000+ kWh.

The high-intent move this week is simple: use your current smart thermostat or provider-portal usage to estimate summer kWh, then test every plan at 1,000, 1,500, 2,000, and 2,500 kWh with delivery charges included. If an advertised rate only looks cheap at exactly 2,000 kWh because of a credit or bundle, check what happens after an HVAC tune-up, filter replacement, vacation week, or milder month drops usage below the threshold.

Quick answer for May 2026 shoppers

CenterPoint and Oncor delivery charges are not optional extras; they are part of the all-in electricity bill. Large homes should compare the full Electricity Facts Label, not just the retail energy charge, and should model plan cost across several usage levels before choosing a familiar brand. Start with the Electricity Facts Label guide, then use the 500 vs 1,000 vs 1,500 kWh comparison framework and extend it to 2,000+ kWh for summer.

If your home has Nest, Ecobee, Honeywell Home, Sense, Emporia, a pool pump, or an EV charger, pair this with the smart thermostat and HVAC plan-shopping checklist. The best plan is the one that fits the actual load shape, not the one with the cleanest marketing line.

Why delivery charges matter more in large homes

Delivery charges usually include fixed monthly pieces and per-kWh pieces. The fixed portion matters for small apartments, but the per-kWh portion becomes more visible when a central AC system, upstairs heat gain, pool equipment, and home charging push the bill past 2,000 kWh. A plan can advertise a tempting energy charge while the all-in bill still rises quickly because delivery is applied to every kWh used.

That is why CenterPoint-area Houston shoppers and Oncor-area Dallas-Fort Worth shoppers should avoid comparing plan screenshots without opening the EFL. The EFL is where average prices at standard usage levels, base charges, delivery treatment, credits, contract length, and renewal language are supposed to come together in a schema-friendly way a human can actually audit.

Provider-watch checklist: Reliant, TXU, Direct Energy, Gexa, Rhythm

Use brand names as a shortlist, not a shortcut. Reliant and TXU Energy may be appealing for app familiarity, rewards, or household trust. Direct Energy, Gexa, Rhythm, and other providers may have competitive fixed-rate, renewable, bill-credit, or time-of-use offers. None of that replaces the same delivery-charge test.

For each plan, write down the base charge, retail energy charge, CenterPoint or Oncor delivery line treatment, bill-credit threshold, free-night or weekend window, early termination fee, and renewal language. Then ask: does this plan still win if the home uses 1,450 kWh after a filter change, 2,150 kWh during an August heat wave, and 1,100 kWh in October?

Smart-home data that improves the comparison

• Nest or Ecobee runtime: Long 3 p.m. to 9 p.m. cooling cycles make free-night plans less automatic because the biggest load may not be movable.
• HVAC filter status: A dirty filter can inflate last month’s usage and make a 2,000 kWh credit look safer than it really is.
• Sense or Emporia monitoring: Always-on load, pool pumps, dehumidifiers, and older refrigerators can explain why a home stays in a high tier.
• EV charging schedule: Tesla, Ford, Rivian, Hyundai, Kia, and ChargePoint schedules can move hundreds of kWh, but only the full home bill decides whether free nights beat fixed rate.
• Provider portal intervals: If the portal shows daily or interval usage, compare weekdays, weekends, and high-temperature days separately.

CenterPoint-area Houston shortcut

Houston-area shoppers can start with 77001 electricity plan data. Build a shortlist, open the current EFL for each offer, and compare the same home at 1,000, 1,500, 2,000, and 2,500 kWh. If a plan depends on hitting a usage credit, check whether basic HVAC maintenance could move the home below that line.

For additional Houston context, review the CenterPoint delivery-charge explainer and the HVAC filter checklist for 2,000 kWh homes before switching.

Oncor-area Dallas-Fort Worth shortcut

Dallas-area shoppers can compare 75201 electricity plan data with the same method. Oncor delivery charges should be included in the all-in bill model, especially for larger homes with two-story cooling, pool pumps, home offices, or EV charging. A plan that looks great at one usage point may not be the safest plan across a full summer.

If you are also comparing provider brands, read the Reliant, TXU, and Direct Energy large-home watch. If an EV is part of the load, use the EV free nights vs fixed-rate guide before picking a time-of-use plan.

The bottom line

For May 2026, the safest large-home shopping workflow is delivery charges first, retail plan structure second, smart-home usage third, and brand preference last. CenterPoint and Oncor charges are part of the bill whether the plan is from Reliant, TXU, Direct Energy, Gexa, Rhythm, or another provider. Betterplan helps turn those moving pieces into plain 2,000 kWh bill math before summer usage makes the wrong plan expensive.
