Divide usage by billing days before judging the spike. A longer bill can hide whether the home actually used more electricity per day.
Long cooling seasons, heat pumps, dehumidifiers, pool pumps, and peak afternoon use are often the first seasonal checks.
Divide the full bill by kWh. If the all-in rate changed, the cause may be supply, delivery, riders, taxes, or fixed charges.
Start with the usage line. If kWh increased, the bill is usually reacting to behavior, weather, appliance runtime, or a longer billing period. If kWh stayed similar, compare the all-in rate, delivery charges, taxes, riders, and fixed customer charges.
For Florida, useful first checks include air conditioning, heat pumps, water heating, longer billing periods, and delivery or fuel riders. The starter electricity rate on the related calculator page is $0.16 per kWh, but the rate printed on your bill is better for a real comparison.

Common reasons include air conditioning, heat pumps, water heating, longer billing periods, and delivery or fuel riders. Compare kWh usage first, then compare the all-in rate and fixed charges.
Compare kWh first. If kWh jumped, usage changed. If kWh stayed flat but dollars rose, rates, delivery, taxes, or fixed charges are more likely.
Yes. A 34-day bill can look much higher than a 28-day bill even when daily usage stayed similar.
