The Florida Power & Light Rate Plan Nobody Talks About
FPL offers different rate structures, and most Port St. Lucie homeowners are on the default flat rate. But switching to time-of-use pricing, combined with a smart thermostat, can save 15-25% on your cooling costs. Here's how.
How Time-of-Use Works With Your AC
Time-of-use pricing charges more during peak demand (typically 2pm-7pm in summer) and less during off-peak hours. A smart thermostat can "pre-cool" your home to 72°F before peak rates kick in, then let it drift to 76°F during expensive hours. Your home stays comfortable because the thermal mass of your house holds the temperature for hours.
The Pre-Cool Strategy
- 11am-2pm: Smart thermostat cools home to 72°F at off-peak rate
- 2pm-7pm: Thermostat raises to 76°F, AC barely runs during expensive peak
- 7pm onwards: Back to normal schedule at off-peak rate
- Result: 60-70% less AC during peak hours = 15-25% monthly savings
Real Port St. Lucie Example
$280/month FPL bill → Switch to time-of-use + ecobee pre-cool scheduling → $195/month. That's $1,020/year saved with zero equipment changes. Add a smart thermostat ($249) and the investment pays back in 3 months.
