Lower Your Texas Electricity Bill

Last updated: October 18, 2026  ·  9 min read

The conventional advice — change lightbulbs, set the thermostat higher, weather-strip your doors — produces real savings. But it's dwarfed by the impact of being on the right electricity plan for your actual usage. This guide ranks the moves by how much they actually save Texas households, from biggest impact to smallest, with the rough payback math for each.

Move #1 — Switch to the Right Plan (Highest Impact)

Most Texas households are on a plan that didn't match their usage at signup, or that has rolled past its contract end date into a much higher holdover rate. Switching to a current best-fit plan typically saves $10 to $50 a month at zero cost, with no installation and no payback period.

The catch: the cheapest plan on Power to Choose (which sorts by the 1,000 kWh advertised rate) is rarely the cheapest plan for any real household. Most households don't use exactly 1,000 kWh every month. The TexasPowerCost.com ZIP search tool calculates true monthly bills using your real usage by interpolating across all three EFL price points. For most households, the best-fit plan is one or two slots different from the headline-cheapest plan.

Move #2 — Raise Your Cooling Setpoint

The Department of Energy guideline of 78°F when home and 85°F when away is the single most effective free intervention. In a Texas summer, every degree above 72°F saves roughly 6% to 8% on cooling cost. The savings come from reduced compressor runtime and a smaller indoor-to-outdoor temperature differential — the physics driving heat transfer through walls and windows.

Households reluctant to set 78°F can split the difference: 76°F when home, 80°F to 82°F when away, 74°F to 76°F for sleeping. A programmable or smart thermostat handles the schedule automatically.

Move #3 — Install a Smart Thermostat

A smart thermostat (Nest, Ecobee, Honeywell T9, or similar) typically saves 8% to 12% on cooling cost in Texas. The savings come from learned occupancy schedules, pre-cooling before the daily heat peak, and gradual setpoint changes. Most TDUs offer rebates of $50 to $100 toward a qualifying smart thermostat installation, shortening the payback to under two years for most homes.

ERCOT-aware smart thermostats also enroll the household in demand-response programs that pay small bill credits each summer in exchange for brief setpoint adjustments during peak grid events. The Texas Smart Thermostat Program is the largest of these.

Move #4 — Improve Attic Insulation

Attic insulation is the highest-ROI structural upgrade for most older Texas homes. A home built before 1990 commonly has R-19 or less in the attic. Adding blown-in cellulose or fiberglass to reach R-38 or R-49 (current code in most of Texas) reduces summer cooling load by 15% to 25%. Federal energy-efficient home improvement tax credits and TDU rebates can shorten payback to 2 to 4 years.

Combined with a radiant barrier — a foil-faced sheet attached to the underside of the roof deck — attic improvements can reduce attic temperature by 20°F to 30°F in summer, directly reducing the load on ductwork running through that space.

Move #5 — Optimize Pool Pump Scheduling

A residential pool pump is one of the largest single loads in a Texas home, often running 8 to 10 hours a day in summer. Switching from a single-speed to a variable-speed pump cuts that consumption by 50% to 80%. Scheduling the pump to run off-peak (overnight or early morning) reduces strain on the grid and pairs well with a time-of-use plan.

Move #6 — Address Vampire Loads and Standby Power

Standby Load	Annual kWh	Annual Cost (13¢/kWh)
Cable/satellite box (always-on DVR)	250 – 450	$33 – $59
Gaming console (instant-on mode)	100 – 250	$13 – $33
Desktop PC + monitor (always on)	200 – 400	$26 – $52
Phone chargers, plug adapters (10+)	30 – 80	$4 – $10
Whole-house standby total	800 – 1,500	$100 – $200

Smart plugs that cut power to devices when not in use, or switching gaming consoles out of instant-on mode, recover most of these costs without changing usage patterns.

Move #7 — Demand Response and Bill-Credit Programs

Many Texas providers and TDUs run demand-response programs that pay small bill credits to participants. CenterPoint EnergyInsight, the Texas Smart Thermostat Program, TXU Free Pass, and Reliant Truly Free Weekends are examples. Total annual savings from these programs are typically $25 to $150 per household per year, on top of the savings from being on the right plan.

Move #8 — Bill Assistance for Eligible Households

Texas low-income households may qualify for LIHEAP (Low Income Home Energy Assistance Program) and CEAP (Comprehensive Energy Assistance Program), administered through the Texas Department of Housing and Community Affairs. The Weatherization Assistance Program (WAP) covers efficiency upgrades for qualifying homes at no cost. These programs don't show up in most plan-shopping advice but can be transformative for eligible households — apply through your local Community Action Agency.

The Texas-Specific Bottom Line

The highest-leverage bill-lowering moves in Texas are switching to a better-fit plan and reducing cooling load. Smart thermostats, demand-response programs, and pool pump scheduling fill in the next tier. LED conversion and standby-load reduction are smaller but cumulatively meaningful. Solar, batteries, and major HVAC replacement are large capital decisions with multi-year paybacks — useful, but rarely the right starting point. The right sequence is plan first, behavior next, capital last.

Common Questions Texans Ask

What is the single biggest way to lower a Texas electricity bill?

For most Texas households, switching to a better-fit electricity plan saves more in the first month than any efficiency upgrade saves in a year. The plan layer has no installation cost, no payback period, and can change a household's effective per-kWh rate by 1 to 4 cents — worth $10 to $50 a month on typical usage.

What thermostat setting actually saves money in Texas?

The Department of Energy recommends 78°F when home in summer and 85°F when away. Each degree above 72°F saves roughly 6% to 8% on cooling cost. For most Texas households the workable balance is 76°F when home in the afternoon, 80°F to 82°F when away at work, 74°F to 76°F for sleeping.

Are smart thermostats worth it in Texas?

For most Texas households, payback is under two years. A smart thermostat saves 8% to 12% on cooling cost in Texas by learning occupancy schedules, pre-cooling before peak heat, and tuning setpoint changes. Most TDUs offer $50 to $100 rebates that shorten payback further. ERCOT-aware models add small annual bill credits via demand-response programs.

Does attic insulation really pay back in Texas?

Yes — typically within 3 to 5 years for homes with sub-code attic insulation. A Texas home built before 1990 often has R-19 or less in the attic; bringing it to R-38 (current code in most of Texas) reduces summer cooling load by 15% to 25%. Federal tax credits and TDU rebates can shorten the payback further.

Is rooftop solar worth it in Texas?

For most Texas homeowners with a south- or west-facing roof and average-to-high consumption, rooftop solar pays back in 8 to 14 years as of October 2026. The 30% federal Investment Tax Credit and falling panel prices have shortened payback meaningfully since 2020. Pair with a solar buyback plan for best economics.

What is a demand response program?

Demand response is when your provider or TDU pays you small bill credits to reduce electricity use during peak grid events. Texas programs include the Texas Smart Thermostat Program, CenterPoint EnergyInsight, TXU Free Pass, and Reliant Truly Free Weekends. Participants typically earn $25 to $150 in credits each summer.

Is LED lighting still worth converting in Texas?

Yes, but the savings are smaller than they once were because lighting is no longer the biggest residential load. A full LED conversion typically saves 5% to 8% of the total electricity bill — meaningful but not transformative compared to plan switching or HVAC efficiency.

How can I lower my bill if I rent?

Most plan-related actions are available to renters: switching providers (you control the account, not the landlord), thermostat strategy, LED conversion, smart plugs, demand-response enrollment, and pre-cooling. Structural upgrades like insulation and HVAC require landlord approval — but the plan and behavior changes alone routinely save renters $20 to $50 a month.

Does turning off lights really save energy in Texas?

Yes, but less than it used to. Lighting is now a small share of a Texas home's electricity, so switching off lights and using LEDs saves roughly 5 to 8 percent of the bill. It helps, but cooling, heating, and your plan choice move the bill far more than lighting ever will.

What can I unplug to lower my electric bill?

Target always-on vampire loads: phone and laptop chargers, TVs and game consoles, cable and set-top boxes, microwaves, and desktop PCs draw standby power even when off. Unplugging them, or using switched power strips, typically trims 5 to 10 percent off a Texas bill. Entertainment centers and older set-top boxes are the biggest single offenders.

What uses the most electricity in a Texas home?

Air conditioning, by far. In a typical Texas home, cooling is the single largest load and can be close to half of a summer bill. After HVAC come water heating, the pool pump if you have one, electric heating in winter, and the clothes dryer. Lighting and electronics are a small share by comparison.
