Home batteries on Florida Power & Light

Can I add a home battery on FPL?

Yes. Adding storage means an updated interconnection application with Florida Power & Light, plus backup switching hardware alongside the battery itself. Because net metering already shifts your midday production to the evening, a battery here generally buys resilience during outages rather than a lower bill.

How net metering works here

As an investor-owned utility, FPL offers net metering under Florida PSC Rule 25-6.065. A customer-owned renewable system must be sized so that it is not expected to produce more than 115% of the home’s annual consumption, and the rule also limits generating capacity relative to the service capacity. Exported energy is tracked as a kWh credit that offsets later consumption, with any remaining credit settled annually at the utility’s avoided-cost rate rather than the retail rate.

What adding storage changes

  • You will need an updated interconnection application, because you are changing what is connected to the grid.
  • Backup switching is a separate piece of equipment from the battery itself. Storing energy is not the same as being able to use it in an outage.
  • The battery changes what you export rather than how exports are credited. Where net metering already offsets evening consumption, storage generally buys resilience rather than bill savings.
  • Your existing inverter matters. An AC-coupled battery sits alongside it; a DC-coupled one usually means replacing or reworking it.

Common questions

Does FPL pay me for excess solar?

Not month to month. Exports accrue as kilowatt-hour credits that offset later consumption. Any credit left at the annual settlement is bought out at an avoided-cost rate, which is well below retail — which is why oversizing a system is poor economics.

How large a system can I install on FPL?

Under Florida PSC Rule 25-6.065 the system must not be expected to produce more than 115% of your annual consumption, and generating capacity is also limited relative to your service capacity. Systems of 10 kW or less use the simplest interconnection tier.

Is my address definitely served by FPL?

Check your bill. Florida service territories do not follow city limits, and an address near a boundary can be served by a different utility — which changes both the net-metering terms and the interconnection process.
