Texas summer bills, and what to do about them
A August bill twice the size of an April one, on a plan whose rate never moved, is the most common electricity complaint in Texas — and almost always the plan working exactly as described.
Cooling is most of a Texas summer bill
Air conditioning is the largest single load in most Texas homes, and its consumption does not rise smoothly with temperature. A cooling system holding a house at a set point works progressively harder as the gap between inside and outside grows, so a stretch of unusually hot days costs disproportionately more than a mildly warm month.
That is why a bill can double while a rate stays fixed. The rate is a price per kilowatt-hour; summer changes how many kilowatt-hours there are.
Billing period length adds to the confusion. A 33-day cycle at the same daily usage costs about 18% more than a 28-day one, and consecutive cycles genuinely vary.
What a fixed rate does and does not protect you from
It protects you from your retailer repricing the energy, which is a real and valuable protection in a hot summer when wholesale prices spike. A customer on a month-to-month variable product has no such protection, and a record-demand August is when that difference becomes visible.
It does not protect you from using more electricity, and it does not fix the delivery charges your utility sets. So a fixed-rate customer can and will see a much larger bill in August — just not because their price changed.
What actually helps
Comparing at the right benchmark, before you sign. If your summer usage runs above 2,000 kWh, the 2,000 kWh column on the Electricity Facts Label is your comparison, and a plan chosen on the 1,000 kWh figure may not be the cheaper one for you at all.
Watching for structural charges that behave badly across a swinging year. A minimum-usage fee costs you in the mild months; a bill credit that depends on crossing a threshold pays out in summer and vanishes in spring. Neither is visible in an advertised rate.
And knowing your contract's end date, because rolling onto a default variable rate in June is the version of this problem that is genuinely expensive.
Charges that only show up in some months
Two of the structures named above behave differently in August than in April.
