Why Is My Electric Bill So High? A Texas Diagnostic Checklist
A shocking electric bill has exactly two possible causes: you used more electricity, or you paid more per unit. Everything below is a version of one of those. Work through this list in order — each check takes a minute, and one of them is almost certainly your answer.
1. Check the kWh number before anything else
Put this month's bill next to last month's and compare the kWh used, not the dollars. If usage jumped, the mystery is in your house (keep reading). If usage is flat but dollars jumped, the mystery is in your plan (skip to #3). This one comparison cuts the problem in half, and most people never do it.
2. It's summer. It's the air conditioning. It's always the air conditioning
Texas homes routinely use double the electricity in July–September that they use in April. Cooling is half or more of a Texas summer bill, and each degree cooler on the thermostat adds several percent. A $260 August after a $130 April, at the same rate, isn't a billing error — it's 2× the kWh. Compare this month's usage to the same month last year, not to spring, before assuming something's wrong.
3. Your contract expired and nobody made you look
This is the most expensive silent event in Texas electricity. When a fixed-rate contract ends and you do nothing, your provider rolls you onto a month-to-month holdover rate — routinely 30–70% above market. Find your contract end date (it's on the bill, often labeled something like "contract expiration"). If it's in the past, you've found your answer, and the fix is a ten-minute switch. The renewal trap guide explains how to never let this happen again.
4. You missed a bill-credit threshold
If your plan advertises a usage credit ("$100 off at 1,000+ kWh") and your usage came in below the threshold this month, the credit vanished and your bill jumped even though you used less electricity — the signature move of the bill-credit trap. Check the bill for a credit line that appeared last month but not this month.
5. Low usage + base fees = high average price
If you're in a small apartment or were away this month, fixed monthly charges (your plan's base fee plus the delivery utility's fixed charges) get spread over very few kWh, and your effective price per kWh soars. The bill is small but feels outrageous per unit. The fix is choosing plans priced well at your usage level — set the slider to 500 kWh on your city's page and re-rank.
6. You're on a variable rate that's been drifting up
Variable-rate plans can change price every month, and they drift upward far more readily than down. Check your bill for the words "variable" or "month-to-month." Compare the average price you actually paid (total ÷ kWh) against your first bill on the plan. If it's crept up a few cents, that's the drift — and a fixed-rate plan is the exit.
7. Something in the house changed
New EV? Pool pump running longer? Space heater in one cold snap? A failing A/C capacitor making the compressor run constantly? A water heater element stuck on? Usage-based mysteries usually have a culprit with a motor or a heating element. If your provider's app shows daily usage (most do, via smart meter data), find the day the jump started and think about what changed that week. A sudden, sustained, unexplained jump with no lifestyle change is worth an electrician's look.
The permanent fix
Whatever the culprit, the same two habits prevent expensive surprises: know your monthly kWh (glance at the number, every bill), and re-shop your plan at every contract end — because the market's spread between a median and a well-chosen plan is $20–$40 every month at typical usage. Our city pages rank every current plan by estimated bill at your usage; that ranking is the ten-minute cure for most of the diseases on this list.
