Why does the demand charge matter so much in Florida?

FPL's GSLD-1 schedule bills the highest per-kW demand charge in the library while its energy rate is comparatively low. For a fast-charging site, the demand charge dominates the bill, so utilization is the single largest economic driver.

Does Florida tax public EV charging per kilowatt-hour?

No per-kWh charging tax is enacted. Two bills — one to add a 6¢/kWh fee, one to exempt charging electricity from sales tax — both failed in committee in 2025 and 2026. Florida's electricity gross-receipts and sales taxes are folded into the modeled FPL rate.

What is the storm cost-recovery rider?

A Public Service Commission-reviewed rider that lets FPL recover grid-hardening and storm-restoration costs on the demand side of commercial bills. It is adjusted annually and has moved by large amounts between filings, making it a variable cost tied to hurricane-season outcomes.

ForgeAsset / Supercharger ROI / Florida

Tesla Supercharger ROI in Florida

Florida is the country's second-largest EV market, and its charging economics are shaped by a bill where the demand charge — not energy — dominates, layered with a storm-hardening cost-recovery rider that moves every year. ForgeAsset models Florida Power & Light's GSLD-1 schedule against Florida's tax stack, with the electricity gross-receipts and sales taxes folded into the rate.

What makes Florida economics distinct

A demand-dominated bill

At FPL, the per-kW demand charge dominates a fast-charging bill rather than the energy rate — the modeled demand charge is the highest in the library, so utilization is the single biggest driver of Florida economics, and the bundled energy rate is comparatively low. Both are shown in the rate table below.

Storm-hardening cost recovery that moves each year

Florida commercial demand bills carry a Storm Protection Plan cost-recovery rider that funds grid hardening and is reviewed annually by the Public Service Commission. It has swung by large amounts filing to filing — a $1.2 billion storm-restoration charge approved in late 2024 came in below projection and triggered a roughly $80 million refund by mid-2026. It is a live cost layer tied to hurricane-season outcomes, folded into the demand side of the rate.

A regulator-built demand-charge relief rider

FPL filed EV-specific schedules (GSD-1EV and GSLD-1EV) designed so low-utilization fast-charging stations are not overwhelmed by peak-demand billing — capping billed demand as a function of energy dispensed. The model omits that cap as a conservative choice, so the modeled demand cost does not reflect the relief a Florida operator could seek.

A large market with no state income tax

Florida has no state personal income tax, and its EV market crossed into incentive-free growth in late 2025 while remaining second nationally in registered EVs. Interstate corridors (I-95, I-75, the Turnpike) double as hurricane evacuation routes, where the state has deployed temporary mobile charging.

Florida tax profile

Sales tax on hardware: 6%
Business personal property tax: 1.69% of equipment value (example rate)
Clean-fuels credit: no program
Per-kWh charging excise: none

Florida tax defaults applied: no clean-fuels credit program exists in Florida (the LCFS revenue line is $0), LLC costs use the $138.75/yr annual report, sales tax uses the 6% state rate (county surtaxes apply only to the first $5,000 per item), and the property-tax default uses the unincorporated Miami-Dade example — county millage varies and both fields are editable in later steps. Florida's 6.95% electricity sales tax and 2.6% gross-receipts tax are already included in the FPL tariff rate. Florida legislative sessions have repeatedly proposed a per-kWh public-charging tax; none is law as of 2026-07.

Florida programs and incentives

FPL EVolution make-ready credit

A utility-side make-ready credit (transformers, switchgear, trenching, conduit) for qualifying Level 2 installs, first-come first-served until the budget is exhausted. DC fast-charging make-ready runs through FPL's rate-case-negotiated program.

FPL GSD-1EV / GSLD-1EV rider (not modeled)

EV-specific schedules that cap billed demand for low-utilization public charging as a function of energy dispensed. The model does not apply the cap, so the modeled demand cost is conservative relative to what these riders can provide.

NEVI (federal, FDOT-administered)

Roughly $198 million over five years for alternative-fuel corridor build-out; each funded station carries at least four 150 kW connectors.

Florida charging market

Florida carries roughly 247 Supercharger stations — the second-largest state footprint — along I-95, I-75, and the Florida Turnpike, corridors that also serve hurricane evacuation. The state's economics are distinguished by a demand-dominated bill and a storm cost-recovery rider that moves with each hurricane season.
