Net Metering in Florida: How It Works and What to Expect

Net metering is the billing mechanism that determines how Florida residential and commercial solar customers receive credit for electricity exported to the utility grid. Florida's net metering framework is governed by state statute and administered through rules set by the Florida Public Service Commission (FPSC), making it a foundational element of any grid-tied solar investment in the state. This page covers the full structure of Florida's net metering policy — how credits are calculated, what drives the economics, where classification boundaries fall, and what common misunderstandings affect decision-making.

Definition and Scope

Net metering in Florida is a billing arrangement under which a customer who generates electricity from a qualifying renewable energy system — most commonly photovoltaic solar — receives a kilowatt-hour (kWh) credit for electricity delivered to the utility grid. That credit offsets the customer's electricity consumption drawn from the grid during the same billing cycle or carried forward to future cycles. The governing statute is Florida Statute § 366.91, which directs investor-owned utilities (IOUs) to offer net metering to eligible customers.

Scope and coverage: This page addresses net metering as it applies to Florida's investor-owned utilities regulated by the FPSC, including Florida Power & Light (FPL), Duke Energy Florida, Tampa Electric Company (TECO), and Florida Public Utilities Company (FPUC). Municipal utilities and electric cooperatives operate under separate governance structures and are not required under § 366.91 to offer net metering on the same terms — their net metering policies fall outside the FPSC's direct jurisdiction and are not covered here. Federal tax treatment of solar generation, addressed separately at Federal ITC and Florida Solar Systems, is also outside the scope of this page.

For a broader orientation to how solar systems interact with Florida's grid infrastructure, the conceptual overview of Florida solar energy systems provides foundational context. The full regulatory context for Florida solar energy systems covers the statutory and FPSC rule framework in greater depth.

Core Mechanics or Structure

Under Florida's net metering framework, a bi-directional meter tracks two flows: electricity consumed from the grid (import) and electricity delivered to the grid (export). The utility bills the customer on the net difference between these two figures within each billing period.

Credit rate: Credits for exported electricity are applied at the utility's full retail rate per kWh — the same rate the customer pays for consumption. This retail-rate credit is the defining feature of true net metering and distinguishes it from lower-value "net billing" or "buy-all/sell-all" arrangements that exist in other states.

Rollover and true-up: If a customer exports more than they consume in a given month, the excess kWh credit rolls forward to the next billing cycle. Florida's IOUs conduct an annual true-up (typically on the customer's anniversary date or at a set calendar date), at which point any remaining annual credit balance is either paid out at the utility's avoided-cost rate or forfeited, depending on the utility's specific tariff. The avoided-cost rate is substantially lower than the retail rate — FPSC proceedings have established avoided-cost values that have historically ranged between $0.02 and $0.05 per kWh, compared to retail rates that exceeded $0.12 per kWh for most Florida IOU customers as of FPSC dockets reviewed through 2023.

Interconnection prerequisite: Net metering cannot begin until a system passes the utility's interconnection review and receives Permission to Operate (PTO). The Florida utility interconnection process governs this step. The utility installs or programs the bi-directional meter upon granting PTO.

System size cap: Under FPSC Rule 25-6.065, net metering is available for systems up to 2 megawatts (MW) in nameplate capacity for non-residential customers. Residential systems are effectively capped by practical roof and structural constraints well below that threshold. System sizing considerations are covered in detail at solar system sizing for Florida homes.

Causal Relationships or Drivers

The economics of net metering are driven by the spread between the retail credit rate and the avoided-cost export rate. When a system is sized to offset roughly 100% of annual consumption — a common design target — the customer maximizes the volume of export that is credited at the full retail rate, minimizing the residual annual balance that would be valued at the lower avoided-cost rate.

Several structural factors shape net metering value in Florida:

• Time-of-use (TOU) rate schedules: FPL and Duke Energy Florida offer optional TOU rates. On TOU plans, the value of an exported kWh varies by time of day, which can either increase or decrease net metering credit value depending on when the system generates relative to when the customer consumes. Solar arrays tilted slightly west of south can shift afternoon generation to better match higher-value afternoon peak periods on TOU schedules.
• Tiered consumption rates: Florida IOU residential rates include tiered blocks (e.g., FPL's 1,000 kWh threshold between tiers). A solar system that reduces consumption into a lower tier produces savings at a lower marginal rate per kWh avoided, which affects the financial case for oversizing a system.
• Fixed charges: Monthly fixed customer charges (typically between $6 and $16 per month across Florida IOUs as of recent FPSC tariff filings) are not offset by net metering credits. These charges persist regardless of how much a customer exports.
• Solar irradiance and system production: Florida's average of 5.0 to 5.5 peak sun hours per day (National Renewable Energy Laboratory NSRDB data) means system production calculations are relatively favorable compared to northern states, but seasonal variation still affects monthly credit accrual patterns.

Classification Boundaries

Net metering in Florida encompasses distinct customer classes with different applicable rules:

Community solar programs, addressed separately at community solar programs in Florida, use a virtual net metering credit mechanism distinct from behind-the-meter net metering.

Tradeoffs and Tensions

Retail-rate credit vs. avoided-cost export: The central tension in Florida net metering policy is whether exporting solar electricity to the grid should be credited at the retail rate or at the lower avoided-cost rate. Utility arguments focus on cost-shifting — the claim that net metering customers reduce utility revenue while still using the grid infrastructure, effectively shifting those fixed infrastructure costs to non-solar ratepayers. Solar advocates and the Florida Solar Energy Center (FSEC) at the University of Central Florida have countered that distributed solar generation provides grid-level benefits (reduced transmission losses, deferred peak capacity investments) that offset or exceed the credit value.

The Florida Legislature addressed this tension in House Bill 741 (2022), which initially proposed phasing down net metering credits but was ultimately not enacted in that form. The legislative debate signaled that the retail-rate net metering structure remains contested and subject to future modification — a material consideration for anyone evaluating a solar investment's long-term economics. Monitoring Florida electric utility landscape developments is relevant to tracking this policy risk.

Interconnection timelines: Florida IOUs are required to process interconnection applications within defined timelines under FPSC rules, but processing delays have been reported, extending the period between installation completion and PTO. During this gap, the system cannot legally export, and no net metering credits accrue.

Battery storage interaction: Adding battery storage changes the net metering calculation by enabling customers to self-consume stored energy rather than export, which can reduce the annual credit balance and shift value from net metering credits to avoided consumption. The tradeoffs involved are covered at solar battery storage in Florida.

Common Misconceptions

Misconception: Net metering means the utility pays cash for exported electricity.
Correction: Florida's net metering provides kWh credits, not cash payments, during the billing year. Only the residual annual credit balance at true-up is potentially paid as cash — and at the much lower avoided-cost rate, not the retail rate.

Misconception: Solar panels eliminate the monthly utility bill entirely.
Correction: Fixed monthly customer charges remain on the bill regardless of net metering credit volume. A system that exports enough to zero out energy charges still results in a monthly bill reflecting fixed fees.

Misconception: Exported kWh credits never expire.
Correction: Florida's net metering tariffs include an annual true-up. Credits that remain unused at the true-up date are compensated at avoided-cost rates or forfeited, depending on the utility's tariff language. Month-to-month carryover is unlimited within the year, but annual rollover of full-value credits is not guaranteed.

Misconception: All Florida utilities offer identical net metering terms.
Correction: FPSC rules govern IOUs only. Municipal utilities and cooperatives set their own terms. Even among IOUs, the exact true-up date, avoided-cost rate used, and billing mechanics can differ between FPL, Duke Energy Florida, and TECO tariffs.

Misconception: Homeowners Associations cannot affect net metering.
Correction: HOA rules can restrict panel placement, affecting system orientation and output, which indirectly affects net metering credit volume. Florida Statute § 163.04 limits HOA authority to prohibit solar installations outright, but aesthetic restrictions on placement remain permissible. Details are at homeowners association HOA rules and solar in Florida.

Checklist or Steps

The following sequence describes the phases a Florida property owner traverses to reach active net metering status. This is a descriptive process map, not professional advice.

1. Confirm utility jurisdiction — Identify whether the property is served by an FPSC-regulated IOU, a municipal utility, or a cooperative. Net metering terms differ by entity type.
2. Review current tariff on file — Download the applicable utility's current net metering tariff from the utility's FPSC-filed rate schedule (available through the FPSC website). Confirm credit rate structure, true-up date, and avoided-cost rate.
3. Size the system relative to consumption — Review 12 months of utility bills to establish annual kWh consumption. System design targets annual generation near or below that figure to minimize end-of-year low-value residual credits. See solar energy production estimates for Florida regions.
4. Obtain required permits — Local building permit and FPSC/utility interconnection application are separate processes. Building permits are governed by local authority having jurisdiction (AHJ) and the Florida Building Code. See Florida building code requirements for solar and permitting and inspection concepts.
5. Pass inspections — The AHJ conducts structural and electrical inspections. Passing inspection is a prerequisite to submitting the interconnection completion notice to the utility.
6. Submit interconnection completion notice — After passing all inspections, the contractor or property owner submits the completion notice to the utility. The utility then schedules any final inspection on its end.
7. Receive Permission to Operate (PTO) — The utility issues PTO in writing. Net metering does not begin until PTO is received. The system should not export to the grid before PTO.
8. Monitor bi-directional meter readings — After PTO, verify the meter is recording both import and export registers correctly. Discrepancies should be reported to the utility promptly. Solar monitoring and performance tracking in Florida covers ongoing monitoring tools.
9. Track annual credit balance — Review monthly bills to monitor rolling credit balance. Evaluate system output relative to consumption. Adjust if operational changes (new appliances, EV charging) materially alter consumption patterns.
10. Review true-up statement — At the annual true-up, verify the utility's avoided-cost credit calculation against the applicable FPSC tariff rate. Retain documentation for tax and warranty purposes.
