How to Lower Your Electric Bill in Texas

Most advice on lowering your electric bill in Texas is wrong — not because the tips don't work, but because they're priced wrong.

A smart thermostat saves you 8–10% on cooling. Solid. Window seals save you 3–5%. Real. LED bulbs save you 75% on lighting, which is maybe 8% of your bill — so 6% net. All legitimate.

But none of them are bigger than the savings from switching your plan to one that costs 2¢/kWh less.

The order of operations matters. Most guides skip it.

The fastest dollar saved is the plan, not the appliance

On a 1,200 kWh monthly bill at 12¢/kWh, you're paying about $144 for energy. Drop the rate to 10¢/kWh and you save $24 a month — $288 a year. No insulation. No new thermostat. No behavior change.

A smart thermostat costs $150-$300 installed and saves you 8% on cooling, which is roughly 6% of your annual bill. That's about $100 a year on the same house. Worth doing — but it pays back over years.

A new high-efficiency AC unit costs $5,000-$8,000 and might save you 15-20% on cooling. Payback period: a decade.

Sealing your attic and adding insulation costs $1,500-$3,000 and saves 10-20%. Payback: 5-8 years.

Switching plans takes 20 minutes and saves you immediately.

This isn't an argument against efficiency upgrades. It's an argument for sequencing. Fix the rate first. Then chase efficiency.

Step 1: Audit your usage

Pull your last 12 months of electric bills. Note the kWh column for each month. Average them, then look at the spread.

A typical Texas household pattern: 800 kWh in February, climbing to 2,200 kWh in August, back to 900 by November. The summer-to-winter ratio is usually 2.5x to 3x.

What you're looking for:

• Your average monthly usage. This determines which plan structure fits you. Under 1,000 kWh: avoid bill-credit plans. Over 1,500 kWh: bill credits often help. Between: read the EFL carefully.
• Your summer peak. Texas plans are most expensive in absolute terms when you're using the most. A high peak means you need a fixed-rate plan more than a low-peak household does.
• Your usage trend year over year. Did your bill go up because you used more, or because the rate went up? Same kWh + higher dollars = a rate problem. More kWh + same rate = a usage problem.

Smart Meter Texas (smartmetertexas.com) gives you 12 months of hourly interval data, free, for any Texas address with a smart meter. The PUCT mandates this. Use it.

Step 2: Re-shop the plan

If you've been on the same plan for more than 12 months, you're probably overpaying. Two reasons:

Auto-renewal pricing. When your fixed-rate contract ends, your REP rolls you to a month-to-month variable rate that's usually 40-100% higher than what they're advertising to new customers. They're allowed to do this; the EFL discloses it. Most customers don't read the disclosure and don't shop.

Rates have moved. Even if you're still on a fixed-rate plan, the market has shifted. A plan that was competitive when you signed in 2024 isn't necessarily competitive in 2026. Compare your current rate to what's available right now.

Run the math: monthly bill × 12 months on your current rate vs. the same usage on a competing plan. If the gap exceeds $120/year, switch. Below that, the friction of switching isn't worth it.

Step 3: Match the plan structure to your usage

Texas plans come in shapes, not just prices. The shape has to match how you actually use electricity.

Flat-rate plans charge the same per-kWh rate at every usage level. Best for: small homes with unpredictable usage, apartments, anyone who hates math.

Bill-credit plans discount your bill (typically $25-$100) when usage falls in a specific band (typically 1,000-1,999 kWh). Best for: households whose usage reliably falls in the credit band every month. Worst for: anyone whose usage fluctuates above or below.

Free-nights or free-weekends plans make off-peak usage free in exchange for higher daytime rates. Best for: night-shift workers, EV owners charging overnight, families who can shift laundry and dishwasher cycles. Worst for: work-from-home households running AC during the day.

Time-of-use plans charge different rates by hour. Best for: households with battery storage or solar that can time-shift. Worst for: anyone who can't move usage away from peak afternoon hours.

If the plan structure doesn't match your usage pattern, the headline rate is fiction. Read the EFL at the usage band closest to your actual monthly average.

Step 4: Reduce usage where it actually moves the bill

Most efficiency tips are real but small. The ones that move the bill in Texas:

Set your thermostat to 78°F in summer, 68°F in winter, when home. Each degree closer to outside temp saves about 1% on heating/cooling — a $5/month bill in summer is meaningful.

Use a programmable or smart thermostat to set back when you're not home. A 7-10°F setback during work hours saves 5-10% on annual cooling/heating. Real money.

Replace incandescents with LEDs. This is mostly done by 2026, but if you still have any, they're roughly 75% less efficient than LEDs. Lighting is 8-12% of a typical bill.

Run the pool pump fewer hours. This is the single biggest hidden load in many Texas homes. A pool pump running 12 hours a day adds 250-400 kWh/month. Cut it to 6 hours during low-demand months and you save $25-50/month with no impact on water quality.

Replace a refrigerator older than 15 years. Pre-2008 fridges use 50%+ more electricity than current ENERGY STAR models. A new fridge costs $700-$1,500 and pays back in 4-6 years on energy alone.

Seal duct leaks. Texas attics are brutal on ductwork. Sealed ducts can cut cooling costs 10-20%. Costs $300-$600 to have a technician do it properly.

Add attic insulation. Texas building code minimums are below modern best practice. Bringing an older attic to R-38 typically cuts cooling costs 5-10%.

What we'd skip:

• "Smart power strips." They save under $20/year in most households.
• Solar tube lights. Cool, but they don't move the bill.
• Unplugging "vampire" devices. Modern electronics have low standby draw. The savings are real but tiny ($30-$60/year max).
• Ceiling fan loops. They make you feel cooler so you can run the thermostat higher; the savings are about the thermostat, not the fan.

Step 5: Time the big appliance loads

Texas REPs increasingly offer plans with off-peak or free-nights pricing. If you're on one, shifting laundry, dishwashing, and EV charging to those hours is real money.

If you're on a flat-rate plan, off-peak shifting doesn't save you anything directly — the rate is the same at 2pm and 2am. But it does take stress off the grid, which (in aggregate) helps everyone.

Some easy shifts:

• Run dishwashers after 8pm
• Run washing machines at night or early morning
• Schedule EV charging from midnight to 6am
• Pre-cool the house before 4pm on hot days, then let it drift to setback temp through the peak

When not to spend money trying to lower your bill

A few cases where investment doesn't pay off:

You're renting. Don't pay for insulation, duct sealing, or HVAC replacement in someone else's house. Shop the plan, control the thermostat, switch out bulbs if your landlord lets you keep them. Stop there.

You're moving in less than 3 years. Most efficiency upgrades have payback periods of 4-10 years. Below 3, you won't recover the investment before you sell.

The marginal cost of efficiency is higher than your bill savings. A $12,000 high-efficiency HVAC upgrade vs. a $6,000 standard replacement saves maybe $300/year. That's a 20-year payback. The premium isn't worth it.

You're paying for "energy audits" that just sell you upgrades. Free utility audits are usually fine; $500 home audits from contractors are usually sales calls in a clipboard.

The honest close

Lowering your Texas electric bill is mostly a plan-shopping problem with a small efficiency tail. Order matters.

Step one is always the rate. Once the rate is right, the efficiency gains compound. But if you're paying 13¢/kWh on a plan that should be 10¢, no amount of LED bulbs and smart thermostats closes the gap.

Shop the rate. Match the structure to your usage. Set the thermostat smarter. Replace the old appliances when they die. Skip everything that sounds like a magazine tip.

That's the order.
