The short answer

Florida Public Utilities Company (FPU) is one of four Florida utilities, alongside FPL, Duke Energy and TECO, that the state requires to credit your solar exports at the full retail rate each month under Florida's net metering rule. Only power your system generates beyond what you use over the whole year gets paid at a separate, lower rate, the same pattern FPL and the others follow.

At about 18.0 cents per kWh, one of the higher rates we cover, a $300 monthly bill needs roughly 10 to 13 kW of solar, and a $400 bill needs roughly 13 to 17 kW. FPU serves two separate areas: parts of Jackson, Calhoun and Liberty counties in the Northwest, and Amelia Island in Nassau County in the Northeast.

How FPU's solar credit works

FPU's net metering tariff was approved effective October 1, 2008, and follows Florida's statewide net metering rule for investor-owned utilities.
Each month, the energy your system generates first offsets your usage at the retail rate, the same way FPL, Duke and TECO work.
Only if your delivered generation for the year exceeds what you purchased from FPU does a separate payment rate apply to that excess, similar to FPL's December true-up.
In FPU's own annual filings, that payment rate has historically been in the range of $0.045 to $0.059 per kWh, well below the retail rate, and it differs slightly by division.

The specific $0.05598 (Northeast) and $0.05940 (Northwest) per-kWh figures above are from FPU's compliance filing for calendar year 2009, the most detailed public source we could find. FPU does not publish a current net excess generation rate on its own site, so these numbers show the structure and rough scale, not today's rate. Ask FPU directly before you size a system.

Two divisions, two rate riders

FPU is not one service area. It runs a Northwest Florida Division, serving parts of Jackson, Calhoun and Liberty counties around Marianna, and a Northeast Florida Division, serving Amelia Island in Nassau County near Fernandina Beach. Each division has its own Rate Adjustment Rider for fuel and purchased power costs, which are updated separately and can differ.

What FPU charges

FPU's residential rate (Schedule RS), effective March 20, 2025, is:

Charge	Amount
Customer Facilities Charge	$24.40 a month
Base Energy, up to 1,000 kWh	2.696 cents per kWh
Base Energy, above 1,000 kWh	4.415 cents per kWh

On top of these base charges, the Florida Public Service Commission adjusts FPU's purchased power charge annually, normally each January, and that adjustment is usually the largest part of the bill. Our calculator uses FPU's average residential rate of 18.0 cents per kWh from federal EIA data, which includes that adjustment.

What a monthly FPU bill needs

The sizes below use 18.0 cents per kWh and cover roughly 75 to 95 percent of a year's use. The last two columns come from the PSC's December 2025 figures for FPU, including the $24.40 Customer Facilities Charge, which stays on the bill however much solar you add.

Monthly bill	System size	Savings a year	Bill left each month
$200 a month	6.5 to 8.3 kW	$1,610 to $2,010	$33 to $66
$300 a month	10.0 to 12.6 kW	$2,570 to $3,160	$37 to $86
$400 a month	13.4 to 17.0 kW	$3,520 to $4,310	$41 to $106
$500 a month	16.9 to 21.3 kW	$4,480 to $5,460	$45 to $127

These are planning numbers, not a quote, before taxes and local fees. FPU nets your solar against your use each month at the retail rate; only the yearly leftover is paid at its lower rate.

Common questions

How much solar do I need with Florida Public Utilities (FPU)?

At about 18.0 cents per kWh, one of the higher rates we cover, a $300 monthly bill needs roughly 10 to 13 kW of solar and a $400 bill needs roughly 13 to 17 kW.

Is solar worth it with Florida Public Utilities?

FPU nets your solar against your monthly bill first, so using your own power is worth the full retail rate. Only when your system generates more than you use over the year does FPU's lower payment rate apply, and historically that rate has been well below retail. Compare our estimate, which is a top end at FPU, with each quote. The federal tax credit ended on December 31, 2025.

How does FPU credit solar power sent to the grid?

FPU's net metering tariff, approved effective October 1, 2008, nets the energy your system generates against your monthly usage first, at the retail rate. Only if your delivered generation exceeds what you purchased from FPU over the year does a separate, lower payment rate apply to that excess.

What does FPU pay for net excess solar generation?

In FPU's own compliance filings, the annual payment rate for net excess generation was $0.05598 per kWh for most of the year in the Northeast Florida Division (Fernandina Beach/Amelia Island) and $0.05940 per kWh in the Northwest Florida Division (Marianna). Those figures are historical, since FPU does not publish a current rate on its own site, so ask FPU for today's figure before you size a system.

Does FPU have different rates for Marianna and Fernandina Beach?

FPU serves two separate divisions with their own rate riders: the Northwest Florida Division, covering parts of Jackson, Calhoun and Liberty counties, and the Northeast Florida Division, covering Amelia Island in Nassau County. Its net excess generation payment has historically differed slightly between the two.

What is FPU's residential electric rate?

Under FPU's tariff effective March 20, 2025, residential customers pay a $24.40 monthly Customer Facilities Charge plus a Base Energy Charge of 2.696 cents per kWh for the first 1,000 kWh and 4.415 cents per kWh above that, plus a purchased power charge the Florida Public Service Commission adjusts annually, normally each January.

Who owns Florida Public Utilities Company?

FPU is a subsidiary of Chesapeake Utilities Corporation and also distributes natural gas. Its electric division served about 33,100 customers as of a 2025 Florida Public Service Commission rate case.

How do I connect solar to FPU?

Contact FPU directly for its current interconnection and net metering application, since it is not posted in detail on FPU's public site. Have your contractor confirm your system meets Florida Public Service Commission Rule 25-6.065 before you sign a contract.

Which utility do I have if I live near Marianna or Fernandina Beach?

Your bill names your utility. FPU serves parts of Jackson, Calhoun and Liberty counties in the Northwest, and Amelia Island in Nassau County in the Northeast. Compare every utility we cover at solar by utility.
