The Texas Summer Bill Spike Survival Guide

A typical Texas household's August electricity bill is roughly double its February bill. That's not a problem — that's the baseline.

The problem is the bills that come in triple. Or quadruple. The ones where the summer increase isn't proportional to usage. The ones where the math doesn't track.

Here's how to tell the difference between a normal Texas summer bill and an actual emergency.

The baseline: what summer "supposed" to look like

A typical Texas household pattern:

• February: 800-900 kWh
• June: 1,300-1,500 kWh
• July: 1,800-2,200 kWh
• August: 2,000-2,400 kWh
• September: 1,500-1,800 kWh

The summer-to-winter ratio is roughly 2.5x. That ratio is consistent across home sizes — apartments swing from 600 to 1,400, large houses swing from 1,500 to 3,800.

The dollar bill follows the kWh, plus a TDU charge that scales with usage. On a 10¢/kWh plan, a 900 kWh February bill is about $135 (energy + delivery + base). The same home in August at 2,200 kWh is about $280.

Doubled. That's normal.

The cause: AC. A Texas summer runs the AC compressor for 12-16 hours a day across June through September. The compressor is by far the largest electrical load in most Texas homes. When it runs continuously, the bill scales with it.

When the doubling isn't a problem

If your bill in August is roughly 1.8-2.5x your February bill, and the kWh column scales similarly, the bill is doing what Texas bills do. The plan isn't broken. The weather is the weather.

What you can do at that point is limited but real:

• Set the thermostat to 78°F when home, 82°F when away. Each degree above outside temperature saves about 1% on cooling.
• Run the pool pump fewer hours. 4-6 hours a day is enough for water clarity. 12 hours is overkill.
• Pre-cool the house early in the morning. Bring the house to 74°F by 7 AM, then let it drift up to 78°F by afternoon. The compressor runs hard early when ambient is cooler (more efficient), less hard during peak.
• Seal duct leaks if you own the home. $300-$600 for a proper sealing job; cuts cooling cost 10-15%.

These are real moves with real numbers. They don't change the fact that August is going to be the biggest bill of the year.

When tripling is the problem

A 3x or 4x winter-to-summer increase is a different signal. Three things to check:

Your usage truly tripled. If kWh went from 900 in February to 2,800 in August — a 3x usage swing on a normal-sized home — something specific changed. Common causes:

• New pool (added 300-400 kWh/month)
• New EV charging at home (added 300-400 kWh/month)
• HVAC system efficiency decline (compressor draws more for same cooling, often signals an aging system)
• Heat-trapping renovations (closed-off rooms, blocked vents)
• More people in the home (kids home from college, etc.)

Your usage doubled but your bill tripled. Now the rate is the issue. Most often this means:

• You're on a variable-rate plan and the REP hiked the rate. Check your per-kWh charge against last month and last summer.
• Your fixed-rate contract expired and you got auto-rolled to month-to-month. The variable rate after auto-renewal is typically 40-100% higher than the fixed rate you were paying.
• You're on a bill-credit plan and your summer usage pushed you out of the credit band. Some plans cap the bill credit at 1,999 kWh. Pass 2,000 and the credit vanishes, jumping your effective rate.

Your usage roughly doubled and your bill roughly doubled, but it's still way more than you remember. This often means your memory is wrong. Most people anchor on their winter bill and forget what last August actually cost. Compare August 2026 to August 2025 specifically. If they're within 10%, the plan and the weather are doing what they did last year.

Red flags: when the plan is the cause

Specific patterns that mean the bill spike is the plan, not the weather:

• Your energy charge per kWh is higher than 14¢ on a non-bill-credit plan. Top-of-market for residential in Texas. Almost certainly a variable-rate or rolled contract.
• Your bill suddenly added a "monthly service charge" or "base charge" of $15+ that wasn't there before. Likely a renewal to a different product. Check your contract documents.
• The TDU delivery charge per kWh jumped by 1¢+. TDU rate cases happen every few years; when one approves, the charge increases overnight. Not your REP's fault, but might prompt re-shopping the energy charge side to compensate.
• A line item like "demand charge," "peak demand fee," or "ERCOT pass-through" appears. These are unusual on residential plans. If you're seeing them, you've been moved to a commercial-class or indexed product. Investigate immediately.

Emergency switches: usually a bad idea

The instinct on a $700 August bill is to switch plans immediately. Usually a mistake. Three reasons:

Mid-contract switches trigger ETFs. $150-$295 to break a fixed-rate contract. If you've got 4 months left and you're saving 1¢/kWh by switching, the savings ($72) don't cover the ETF.

You can't lock summer pricing in July. Whatever fixed-rate plan you find right now is priced for summer demand. The rate is high; the lock is at a bad moment. You'll regret it in November when prices fall.

The bill might come down on its own. August is the peak month. September is meaningfully cooler. October is mild. If you've got 2-3 months until your contract expires, riding it out costs less than panicking.

The exceptions: if you're on a variable-rate plan and the REP just hiked the rate, switch immediately. If your contract has already expired and you're on a rolled month-to-month rate, switch immediately. In both cases, the bleeding is happening now and a switch — even to a slightly suboptimal long-term plan — stops it.

Building a summer-proof plan for next year

The real fix for summer bill anxiety happens in October-November of the previous year:

1. Lock a 12-month or 24-month fixed-rate plan in November. The rate floor of the year. Insulates you from next August.
2. Match the plan structure to your actual usage. If you're a high-usage household, a bill-credit plan with a high-threshold credit (1,000-2,999 kWh) works. If you're a low-usage household, flat-rate.
3. Mark the contract expiration on a calendar. Two months before, schedule a re-shop. Don't let the contract auto-roll.
4. Buy whatever efficiency upgrades pay back fastest. Smart thermostat, duct sealing, attic insulation. Each shaves percentage points off the August bill.

The household that's been doing this for 3 years has summer bills that surprise no one. The bill is what it is, the plan is locked, the efficiency moves are done. August is hot. August is expensive. It doesn't have to be panic-inducing.

When to actually worry

A handful of cases where the August bill is signaling a real problem:

Your AC isn't getting the house to the thermostat setting. Set thermostat to 78°F but the indoor temp stays at 82°F? The AC system is failing. Usage spikes because the compressor never cycles off. Get an HVAC tech to diagnose — usually a refrigerant leak or compressor decline.

The bill went up dramatically without weather change. A 60% bill increase in a mild September compared to last September isn't weather; it's rate. Investigate the plan structure.

You're getting disconnect notices despite paying on time. Billing system glitch or REP cash-flow issue. Document everything. Contact the PUCT if your REP doesn't resolve quickly.

Recurring "estimated bill" entries on your statement. TDU meter reads should be actual, not estimated, for most billing cycles. Repeated estimates can mean a meter issue. Call your TDU.

The honest close

Texas summer bills are big. They're supposed to be. The work is distinguishing "normal big" from "broken big."

If your usage scaled with the heat and your rate is what your contract says it is, the bill is the bill. There's no clever switch that gets you out of paying for AC running through July and August at the rate of a typical Texas home.

If the math doesn't track — usage didn't scale, the rate moved, the plan structure changed — that's worth investigating. Usually it's an auto-renewal or a variable-rate hike, both fixable by switching to a new fixed-rate plan.

The seasonal pattern is reliable. Use it. Lock in November, ride out August, repeat.

That's the loop.
