Best Electricity Plans for Large Homes & Pool Owners

If your Texas home uses more than 2,000 kWh in an average summer month, the cheapest plan on most comparison sites is probably wrong for you.

Large homes — 2,500+ sq ft, pool-owning households, all-electric homes with electric heat — fall outside the usage band that most marketing rates are tuned for. Some plans punish heavy usage. Others reward it. The ones that reward it aren't the ones at the top of "cheapest!" lists.

Here's the high-usage shopping math.

Why large-home shopping is different

The standard rate on a Texas comparison page is calculated at 1,000 kWh of monthly usage. That's roughly a 1,200 sq ft apartment.

A 2,800 sq ft Texas home with a pool, central AC, and a gas furnace runs 1,800-2,400 kWh in average months and 3,000-4,000 kWh during peak summer. The "1,000 kWh rate" is a fictional number at that scale.

What changes at high usage:

• Bill credits at the 1,000-1,999 kWh band start to work in your favor. A $75 credit that requires hitting 1,000 kWh is virtually guaranteed at 2,000 kWh. The plans that punish apartments reward houses.
• Tiered rates can flip. Some plans charge a higher rate for the first tier (0-500 kWh) and a lower rate above it. At 2,500 kWh, the blended rate is meaningfully below the headline.
• Per-kWh delivery charges (TDU pass-through) get larger in dollar terms. Your TDU charge at 1,000 kWh might be $48; at 2,500 kWh, it's $120. The total dollar amounts are large enough that small efficiency moves pay back in months.
• Bill volatility increases. A 30% summer-to-winter usage swing on 2,500 kWh is a much bigger absolute dollar swing than the same percentage on 800 kWh.

The plan you want is one that recognizes the usage and prices it accordingly — usually a bill-credit plan with the right threshold, or a tiered fixed-rate plan designed for heavy users.

Bill-credit plans that actually work at high usage

A bill credit at 1,000-1,999 kWh works for households whose usage reliably falls in that band. For large homes, that's most months from October through April.

In summer (May-September), a large home typically pushes past 2,000 kWh — sometimes past 3,000. If the bill credit caps at 1,999 (which most do), you lose the credit during your highest-usage months. The plan saves you money in winter, costs you more in summer.

A subset of plans offer credits at higher thresholds — typically 2,000-2,999 kWh. These work for large homes year-round. They're less common, and the per-kWh underlying rate is usually a touch higher than the 1,000-band plans. But for households that consistently sit above 2,000 kWh, they're often the optimal play.

The right way to think about it: don't pick the plan with the biggest credit. Pick the plan whose credit threshold matches your real usage band most months of the year.

Pool pumps: the hidden 300 kWh/month

A standard 1-HP pool pump running 12 hours a day uses about 270 kWh/month. A 1.5-HP pump uses 400+. Pools running variable-speed pumps on a smart timer use 100-150 kWh.

For pool-owning Texas households, the pool pump can be the single biggest "hidden" load — a quarter to a third of total monthly usage. Most pool owners haven't measured it specifically because it doesn't appear as a separate line on the bill.

If you have a pool:

1. Check what kind of pump you have. Old single-speed pumps are usually 1-2 HP and run constantly. Variable-speed pumps adjust to need.
2. Measure runtime hours. A clean pool needs 4-6 hours of pump runtime daily, not 12. Most pumps are over-scheduled by default.
3. Replace if it's a single-speed pre-2014 unit. Variable-speed pumps cost $700-$1,500 installed and pay back in 1-2 years from energy savings alone.

When you're shopping a plan, factor pool pump usage in. A 2,500 kWh house with a 350 kWh pool pump is shopping at 2,850 kWh, not 2,500.

Fixed-rate vs. bill-credit at high usage

For large homes that consistently fall above 2,000 kWh:

• Bill-credit plans with high-threshold credits can deliver effective rates 1-2¢/kWh below comparable flat-rate plans during the credit-eligible months.
• Flat-rate plans lose some absolute savings but eliminate the threshold risk entirely.

The math:

For a household using 2,400 kWh/month in summer and 1,500 kWh in winter:

• Bill-credit plan ($75 off if 1,000-1,999): credit applies in winter only. Summer effective rate = underlying rate (~12¢). Winter effective rate = underlying rate minus credit (~9.5¢). Annual blended: ~10.8¢/kWh.
• Flat-rate plan at 10.5¢/kWh: every month at 10.5¢. Annual blended: 10.5¢/kWh.

Flat-rate wins this household by ~0.3¢/kWh. On 2,000 kWh average usage, that's $72/year.

If the household uses 2,500 kWh year-round (large all-electric home):

• Bill-credit plan with $75 off if 2,000-2,999 kWh (the high-threshold version): credit applies every month. Effective rate: ~9.5¢.
• Flat-rate plan at 10.5¢/kWh: every month at 10.5¢.

Bill-credit wins by ~1¢/kWh. On 2,500 kWh, that's $300/year.

The choice between flat-rate and bill-credit at high usage hinges entirely on whether your usage is predictable enough to reliably hit the threshold. For pool homes with consistent summer-heavy patterns, bill-credit usually wins. For homes with high variability (snowbirds, family-size that changes seasonally), flat-rate is safer.

Why fixed-rate matters more for large homes

Large homes are the most exposed to bill spikes. A 3,500 kWh August bill on a variable-rate plan at the wrong moment can run $700-$1,000.

After Winter Storm Uri (February 2021), several large-home customers on variable or indexed plans received bills of $5,000-$15,000 for a single billing cycle. The structural risk was always there — Uri made it concrete.

For high-usage homes, fixed-rate is essentially mandatory. The savings potential of variable-rate (sometimes a slightly lower rate in mild years) is dwarfed by the downside risk in event years.

Pick a 12-month or 24-month fixed-rate plan. The 24-month version typically prices 0.5-1.5¢ below the 12-month at the same usage — and on a 30,000 kWh annual consumption, that's $150-$450/year in savings over the contract term.

Tiered plans designed for heavy users

A subset of Texas plans use a tiered structure: one rate for the first X kWh, a different (usually lower) rate above. Common tier breakpoints: 500 kWh, 1,000 kWh, 2,000 kWh.

For an example tiered plan:

• 0-1,000 kWh: 12.5¢/kWh
• 1,001-2,500 kWh: 9.5¢/kWh
• 2,501+ kWh: 8.5¢/kWh

A 2,500 kWh month on this plan: (1,000 × 12.5¢) + (1,500 × 9.5¢) = $267.50. Blended rate: 10.7¢/kWh.

That's competitive with a flat-rate plan and tolerates the same usage variability without threshold risk. Tiered plans are less common in the Texas market than bill-credit plans, but they're worth searching for at high usage levels.

What to skip

A few patterns to refuse:

Free-nights or free-weekends plans. Same trap as for EV owners but worse — large homes have heavier AC usage during peak hours. The daytime rate eats the off-peak savings.

Variable-rate or indexed plans. Non-negotiable for high-usage homes. The downside risk is catastrophic.

Plans with caps below your average usage. Some plans implicitly assume you won't exceed a certain monthly usage. If you regularly exceed it, the per-kWh rate above the cap can be punitive (15-18¢/kWh on the over-cap portion). Read the EFL's footnotes.

"Energy management" plans that require smart-thermostat compliance. A few REPs offer plans with conditional pricing tied to letting them control your thermostat during peak events. For large homes with high comfort requirements, the loss-of-control costs more than the rate discount earns.

Solar + battery interactions

For large homes with rooftop solar, the plan shopping math changes meaningfully. Solar production peaks during the same hours that draw the highest prices on free-nights and TOU plans, partially offsetting the cost. Battery storage extends the benefit further by letting you arbitrage low-price hours into high-price hours.

Most Texas REPs treat solar households on a "net metering" or "buyback" basis — you export to the grid during high-production hours and earn credit. The rate at which excess solar is credited varies by plan; some plans credit at retail rate, most at a lower wholesale-equivalent rate.

For solar households, the conversation about plan structure deserves its own analysis. Generally:

• If you have solar without battery: net-metering plans matter most
• If you have solar with battery: TOU and time-shifting plans can become viable
• If you have neither: stick with the bill-credit or flat-rate guidance above

The honest close

Large homes get the inverse problem from apartments: the Texas plan market is mostly tuned to 1,000 kWh, and high-usage households have to do extra work to find plans that actually price their usage well.

The shopping pattern:

• Estimate your annual average kWh — including the pool pump
• Filter for plans that reward your actual usage band (bill credits with appropriate thresholds, tiered structures)
• Stay fixed-rate — large-home variable exposure isn't worth it
• Read the EFL at your real usage, not 1,000 kWh
• Skip the "cheapest plan!" headlines — they're not your plan

A right-sized plan for a 2,500 kWh house typically saves $300-$600/year compared to the wrong plan. That's the cost of one good HVAC tune-up. Worth the 30 minutes of shopping.
