The fastest way to lower an electricity bill in Texas is to attack the two biggest cost drivers at once: the rate you pay per kWh and the kWh you use, because cutting only one of them leaves real money on the table.
The average Texas residential customer used 1,176 kWh per month in 2022 and paid an average retail rate of 13.7 cents per kWh, according to the U.S. Energy Information Administration (EIA). That works out to roughly $161 a month before taxes and fees. In summer, when central air conditioners run for eight or more hours a day, that number can climb past $250. The steps below are ranked by typical impact, so readers who have limited time can prioritize.
Step 1: Read Your Bill Correctly Before Doing Anything Else
Most Texas electricity bills blend three separate charges into one confusing total: the energy charge (cents per kWh), the Transmission and Distribution Utility (TDU) delivery charge (set by your local utility, not your retail provider), and fixed monthly fees. The TDU charge is regulated by the Public Utility Commission of Texas (PUCT) and cannot be changed by switching providers. Oncor customers, for example, paid a TDU delivery charge of roughly 3.8 cents per kWh in 2023, plus a fixed monthly charge near $10. Knowing this prevents the common mistake of blaming the retail provider for a charge that no provider can reduce.
Step 2: Compare Plans on Power to Choose
Texas law requires all retail electric providers (REPs) to post standardized Electricity Facts Labels (EFLs) on the PUCT-managed site PowerToChoose.org. The EFL lists the average price at 500 kWh, 1,000 kWh, and 2,000 kWh. Always use the column that matches your actual monthly usage, because many plans include a bill credit that makes the 1,000 kWh price look attractive while the 900 kWh price is significantly higher.
As of mid-2024, competitive fixed-rate 12-month plans from providers such as Rhythm Energy, Chariot Energy, and Gexa Energy have listed rates ranging from roughly 11 cents to 14 cents per kWh at 1,000 kWh (rates vary by TDU territory and change frequently; always verify on the EFL before enrolling). Switching from a month-to-month holdover plan, which can exceed 16 cents per kWh, to a competitive fixed-rate plan at 12 cents saves about $47 per month at average Texas consumption. That is roughly $564 per year for doing nothing more than signing up online.
When not to switch: If a current contract has an early termination fee (ETF) of $150 or more and fewer than three months remain on the contract, it is usually better to wait. The math rarely favors paying a large ETF to save a few cents per kWh.
Step 3: Set the Thermostat to 78°F When Home, 85°F When Away
The Department of Energy estimates that each degree of setback saves approximately 3 percent on cooling costs. Moving from 72°F to 78°F when home reduces cooling energy by roughly 18 percent. A programmable or smart thermostat that automatically raises the setpoint during work hours can cut air conditioning costs by 10 to 15 percent annually, according to ENERGY STAR data. At Texas summer rates, that is $20 to $35 per month during peak cooling season.
Step 4: Change HVAC Filters Every 30 to 90 Days
A clogged filter forces the air handler to work harder, increasing runtime and energy draw. A standard 1-inch filter should be replaced monthly during summer in most Texas homes. Thicker 4-inch media filters can last up to 90 days. Clean filters also extend equipment life, reducing the chance of a compressor failure during a heat wave, when HVAC technicians are booked weeks out.
Step 5: Seal Air Leaks Around Doors and Windows
The EIA reports that air infiltration accounts for 25 to 40 percent of heating and cooling energy use in an average home. Weatherstripping on exterior doors costs roughly $20 to $50 per door and can be installed in under an hour. Caulking around window frames costs less than $5 per window. These are among the highest return-on-investment improvements available to a Texas renter or homeowner.
Step 6: Add Attic Insulation to R-38 or Higher
Texas attics often reach 140°F in summer. The recommended insulation level for most of Texas (IECC climate zones 2 and 3) is R-38 to R-60. Homes built before 1990 frequently have R-11 or less. Adding blown-in insulation to reach R-38 typically costs $1,500 to $2,500 for a 1,500-square-foot attic and can reduce cooling costs by 15 to 20 percent, according to the North American Insulation Manufacturers Association. Many Texas utilities offer rebates of $150 to $500 for attic insulation upgrades; check with the local TDU for current programs.
Step 7: Switch to LED Lighting Throughout the Home
LED bulbs use 75 percent less electricity than incandescent bulbs and last roughly 15 times longer, according to the Department of Energy. Replacing 20 incandescent bulbs with LEDs saves approximately $100 per year in a typical Texas home. The upfront cost has dropped to under $2 per bulb at most hardware stores, meaning payback occurs within weeks.
Step 8: Unplug Vampire Loads
Devices that draw power in standby mode, including televisions, game consoles, cable boxes, and phone chargers, can account for 5 to 10 percent of a home's electricity use, according to the Lawrence Berkeley National Laboratory. Smart power strips that cut power to peripheral devices when a main device is off cost $20 to $40 and eliminate most of this waste automatically.
Step 9: Run Large Appliances Off-Peak If on a Time-of-Use Plan
Some Texas REPs offer time-of-use (TOU) or free-nights plans that charge lower rates between 9 p.m. and 6 a.m. If a household is on one of these plans, shifting dishwasher, washing machine, and dryer loads to off-peak hours can reduce the effective rate paid on those appliances by 30 to 50 percent. However, households that cannot reliably shift usage should avoid TOU plans, because on-peak rates are substantially higher than a standard fixed rate and can increase the bill if usage patterns do not change.
Step 10: Install a Smart Thermostat and Use Its Scheduling Features
Smart thermostats such as the Google Nest or Ecobee cost $150 to $250 and qualify for a $50 federal tax credit under current IRS rules. Their value is not in being smart; it is in enforcing a consistent schedule that most households fail to maintain manually. Studies by Nest found average savings of 10 to 12 percent on heating and 15 percent on cooling, though results vary by climate and prior thermostat habits.
Step 11: Check for Provider Bill Credits and Loyalty Incentives
Some REPs offer bill credits for customers who stay below a certain usage threshold (often 500 kWh or 1,000 kWh). These credits are displayed on the EFL and can make a plan with a higher base rate cheaper in practice for low-usage households. A one-bedroom apartment using 650 kWh per month may pay less on a plan with a $50 bill credit at 1,000 kWh than on a plan with a slightly lower rate and no credit. The arithmetic requires using the EFL, not the advertised headline rate.
Step 12: Request a Free Home Energy Audit
All Texas investor-owned utilities are required by the PUCT to offer free or low-cost home energy audits to residential customers. Oncor, CenterPoint, AEP Texas, and Texas-New Mexico Power all maintain audit programs. A certified auditor will identify insulation gaps, duct leaks, and equipment inefficiencies that are difficult to find without diagnostic tools. Duct leakage alone accounts for 20 to 30 percent of cooling energy loss in many Texas homes, according to ENERGY STAR, and sealing ducts is often a utility-rebated improvement.
The Bottom Line
Lowering a Texas electricity bill does not require a single dramatic action. It requires stacking several modest improvements across both the rate paid and the energy consumed. A household that switches to a competitive fixed-rate plan, adjusts the thermostat schedule, seals air leaks, and replaces incandescent bulbs can realistically cut monthly costs by $60 to $100 without significant capital investment. Larger improvements such as attic insulation and duct sealing push savings higher and persist for years.
