Understanding FPL Peak and Off-Peak Rates in Florida
Florida Power & Light (FPL) offers residents the option to switch from standard flat-rate billing to a Time-Of-Use (TOU) rate plan. This structure incentivizes customers to shift their electricity usage away from high-demand hours to lower-demand periods. By understanding how these rates work, Florida homeowners can potentially lower their monthly utility bills significantly.
Use the FPL Peak and Off-Peak Rates Florida Calculator above to estimate your potential savings based on your specific consumption habits.
What Are Peak vs. Off-Peak Hours?
The core concept of the TOU plan is that electricity is more expensive when everyone needs it (Peak) and significantly cheaper when demand is low (Off-Peak). FPL defines these periods differently depending on the season:
Summer Season (April 1 – October 31)
On-Peak Hours: 12:00 PM (Noon) to 9:00 PM, Monday through Friday.
Off-Peak Hours: All other hours, including weekends and holidays (Memorial Day, Independence Day, Labor Day).
Winter Season (November 1 – March 31)
On-Peak Hours: 6:00 AM to 10:00 AM and 6:00 PM to 10:00 PM, Monday through Friday.
Off-Peak Hours: All other hours, including weekends and holidays (Thanksgiving, Christmas, New Year's Day).
Analyzing the Costs
When deciding whether to switch to a Time-Of-Use rider, you must look at the rate differential:
Standard Rate (RS-1): You pay a flat rate (plus fuel charges) for every kilowatt-hour (kWh) you use, regardless of the time of day. This is typically around $0.11 to $0.13 per kWh depending on total usage tiers (first 1,000 kWh vs above 1,000 kWh).
Time-Of-Use Rate (RTR-1):
On-Peak: The rate is significantly higher (often nearly double the standard rate, e.g., $0.20+ per kWh).
Off-Peak: The rate is significantly lower (often half the standard rate, e.g., $0.06 – $0.07 per kWh).
Who Benefits from Time-Of-Use Rates?
Not everyone saves money on this plan. If you work from home and run the air conditioning heavily between 12 PM and 5 PM in July, your bill might actually increase. However, the TOU plan is ideal for:
EV Owners: Electric Vehicle owners who schedule charging for overnight (after 9 PM or midnight) can charge their cars for pennies on the dollar.
Pool Owners: If you have a variable speed pool pump, scheduling it to run exclusively during off-peak hours can result in massive savings.
Flexible Households: If you can delay running the dishwasher, washing machine, and dryer until weekends or late evenings, you will maximize your off-peak percentage.
How to Maximize Savings
To make the math work in your favor, aim for an Off-Peak usage of 85% or higher. You can achieve this by:
"Pre-cooling" your home before noon in the summer and raising the thermostat during peak hours.
Installing a smart thermostat to automate temperature adjustments.
Using timers for water heaters and pool pumps.
Before switching, review your current bill to determine your average monthly kWh usage, then input your estimates into the calculator to see if the switch is financially sound for your household.
